An A13 Bionic 7-nanometer chip and a third-generation Neural Engine are found inside the iPhone 11. Apple claimed at the time of its release that the A13 Bionic was the fastest chip ever in a smartphone, having a 20% faster CPU and GPU than the A12. The A13’s Machine Learning Accelerators enable the CPU to perform over 1 trillion operations per second, and the Neural Engine is quicker than previous chips for real-time photo and video analysis.

An Intel modem chip with Gigabit-class LTE, 2×2 MIMO, and LAA, Wi-Fi 6 compatibility (802.11ax) with 2×2 MIMO, Bluetooth 5.0, Dual-SIM with eSIM, and an Apple-designed U1 Ultra Wideband chip that enhances spatial awareness and enables for improved indoor tracking are all included in the iPhone 11.

Unlock your T-Mobile phone without Account

1. Using a Hardware Unlock Solution

unlock your T-Mobile phone

Unlocking a T-Mobile phone without a T-Mobile account is possible via adjusting the phone’s hardware. There are numerous techniques you may take with this strategy, but you’ll almost always need to contact a specialist to handle it, or you can use a sim card and a module that can be installed into your phone if it is an iPhone. The chip inside the hardware will bypass the carrier lock when you set the ICCID Code in ICCID mode.

But you should also know that messing around with phone hardware in any way will void your warranty. It’s not a permanent solution and you can’t unlock blacklisted phones.

Hardware unlock method is far riskier than most of the other options.

Each year Apple releases a new iPhone series, we know that it only gets more expensive. However, this year is an exception. This year’s entry-level iPhone 13 in the series is priced just the same as the iPhone 12 and iPhone 12 Mini, and Apple dropped heir prices dropped so people are encouraged to buy the latest iPhones this year. 

That should make you think just how fast the iPhone depreciates in value. The iPhone 12 and iPhone 13 only differ by $100, which makes the latter, being the latest, the more viable option for many. But is it really? 

Before you upgrade to the iPhone 13, let’s take a look at what you’re actually buying and discuss any new features or new design upgrades versus the iPhones before it and the flagship Android devices within its price range.


  • Ceramic Shield for better protection 
  • IP68 water and dust resistance 
  • Updated 6-Core CPU and Chipset 
  • Added new camera sensors 
  • Better Camera stabilizers 
  • Long battery life 


  • The design didn’t change from last year’s iPhones 
  • The new camera alignment didn’t offer any new value 
  • No power brick in the box
  • No plastic shrink wrap for added protection 
  • The camera bump is still there and thicker
  • It is heavier than the iPhone 12 

Unlocking iPhone 13: Design and Build Quality

There is a good reason why the iPhone 13’s price is just the same as the iPhone 12’s. It’s because they hardly changed anything on the outside. The design of the phone is just the same as the iPhone 12, even the build materials used are the same. 

Can be argued, but we dare say the iPhone 13’s design is recycled from that of the iPhone 12.   

Moreover, the aluminum frame and the corning glass front and back cover are just the same. Apple says there is a 1mm difference between the two, but you can hardly see that when both are laid flat on a surface. 

The notorious camera bump in the back is still there, albeit with a little difference in the arrangement.  The cameras are of the same quality.

There is a substantial difference in the weight of the two phones because the iPhone 13 packs a bigger battery than that of the iPhone 12, which of course, explains why the iPhone 13 has longer battery life. The iPhone 13 has 3,227 mAh.

On the other hand, the iPhone 13 is sitting on Apple’s fastest and latest chipset and with a faster RAM and bigger internal memory.

Fix sim not provisioned mm2 ATT Verizon Straight Talk

The sim card is the chip that came with the phone and it not only saves data from texts or calls you received or made, it helps your phone connect to your carrier’s network. Sim not provisioned MM2 error is common among android phones. 

But don’t worry, this error is not difficult to fix. As long as you know what the reason for the error is, you’ll be able to fix it. And in this article, we’ll show you quick and easy troubleshooting tests that you can do to fix sim not provisioned mm2 or sim not provisioned error. 

What does sim not provisioned mm2 mean?

If the SIM card is not properly inserted, if it was damaged, or if it was not activated on your network, you will not be able to make or receive calls or texts, and you will see errors on your phone such as ‘sim not provisioned’, ‘phone not allowed for voice’, or ‘sim not provisioned mm2’. 

Other reasons for the sim not provisioned error to pop up are: 

  • You are no longer in your carrier’s coverage area and not activated for roaming. 

If you are indeed “roaming” or outside your carrier’s coverage area, you have to insert a SIM card from other carriers that are servicing the area you’re in. 

On the other hand, for this to work, you must ensure that your phone is not locked to your carrier. Otherwise, using another carrier’s sim card will not work. 

Removing the carrier lock on your phone is an easy and straightforward process and if your carrier won’t or can’t do it for you, you can do it safely with UnlockBase. Go here: https://www.unlockbase.com/unlock-phone/

  • You are using a new sim card that was not activated together with your device. 

If you have a new SIM card, it might take 24-48 hours before it’s fully activated by the carrier. 

How to fix SIM not provisioned error: 5 Ways

Sim not provisioned 
What does sim not provisioned mean
how to fix Phone not allowed for voice

What do you do when you see the sim not provisioned for voice error pop up? 

Identifying the reason why this error appears in the first place is the first step to fixing it. Let’s start with the simplest, most obvious reason and that is the appearance of the sim card. 

  1. Check SIM card for possible damages. 
  • Take the sim card out. Are there dents, damage, or possible scratches? 
  • Are you properly inserting the sim card to the sim slot? 
  • Is it the right sim card size? 
  • Is there dirt in the sim card or the sim card slot? 

You have to make sure the sim card and the sim card slot have no damage or dirt in them before you start using your phone. If this is the case, then you’ll have to replace the SIM card with one from your carrier. 

If you are using postpaid or you want to use the same phone number on your new SIM card, you have to activate the new sim card together with your device. They will ask you to provide the SIM card’s ICCID and your phone’s IMEI, both are the serial numbers assigned to them. 

If you have an older phone model, the sim card might be located at the back, below the battery. You have to remove the battery to access the sim card slot. Newer phones have a sim card slot on the side. 

  1. Re-insert and restart your phone. 

If the SIM card and the sim card slot (caddy) is not showing any physical signs of damage or dirt, try refreshing your phone’s system with a restart. 

Sometimes, a simple restart can fix SIM card not provisioned error. 

This error could have happened because the phone took longer than usual to connect with your sim card or just hiccups in its system that’s not too big to be worried about. 

  1. Enable Airplane Mode 

If restarting your device is not fixing it, you may try putting your phone on Airplane mode. Airplane mode disconnects your phone from any network. Tap Airplane mode again to enable your phone to reconnect. 

If you still see Sim not provisioned mm2 or sim not provisioned for voice error on the phone, your SIM card might not be activated. 

  1. Try the SIM card on another phone. 

This is an option if you are not sure whether it’s the SIM card or the sim card slot that’s malfunctioning. If you have a spare phone that’s working, you can try inserting the SIM card you have on that phone. 

But if it is detected by the other device, then it means the SIM card itself is functioning. If it’s not detected and it’s a new sim card or there’s no damage on the outside, then it’s likely that the SIM card is not activated by your carrier. 

NOTE: If you are inserting the sim card on a postpaid phone that uses a different carrier, your sim card will not work and you will see an error that would say ‘SIM not valid’ or ‘SIM not supported”. 

Related: How to fix sim not supported error 

  1. Activate your SIM card by contacting your carrier. 

Is your SIM card new? Are you using an old SIM card on a new phone? 

As we mentioned earlier in this article, it takes 24-48 hours to activate a new SIM card. If this is the case for you, all you need to do is wait for the time allotted for the SIM or phone to be activated. 

If you are using an old SIM card on a new phone, you have to inform your carrier that you wish to use the old SIM so they can ‘register’ and have it activated together with the new phone. 

Usually, new phones come with a new SIM card as well and that comes pre-registered with the phone. Also, you have to make sure your phone is compatible with your old SIM card. 

Conclusion: Troubleshoot  SIM not provisioned MM2 in under 5 minutes 

We hope the steps above helped you fix SIM not provisioned MM2 error. They will help know in under 5 minutes what the problem is and how to fix it. 

Did we miss anything here? Have you had this error before? How did you fix it? Let us know in the comments!

A device with a locked SIM can’t make or receive calls and may not be able to receive text messages as well. If you wish to unlock your SIM card, you can contact your carrier since all cellular providers are required by law to unlock SIM cards for free, assuming your contract has ended.

If that is not possible, this guide will show you what it means to have a sprint sim card locked and how to fix it.

Why would a SIM card be locked?

SIM cards are installed on most cell phones. They are memory chips used in mobile devices to store information such as your account number, phone book, texts, and other data. Carriers often ‘lock’ the phones that you purchase from them because they want to ensure you will continually use their services.

On the other hand, you will also see a Sprint sim card locked error if you are switching to a new phone or device using a sim from your old phone. That is because your phone’s serial number (IMEI) and the SIM card’s unique identifying number (ICCID) must be registered together. If they don’t match in your carrier’s system, you will see this error.

If you have been given a new phone for a replacement and you wish to use the same SIM card from your previous device, you have to call your carrier and have them register that SIM card together with your new phone.

What does Sprint SIM card locked error mean?

sim not valid and sprint sim card locked are common errors you see on carrier locked phones

Like any other mobile service provider, Sprint also ‘locks’ the phone that you get from them. If your phone is ‘locked’ or if you see a Sprint SIM card locked error, it means you’re not going to be able to use their current Sprint-branded handset on another carrier’s network unless your device is unlocked.

Moreover, a locked phone is subject to roaming charges when taken outside of Sprint’s service area and network because the phone is programmed to work only with Sprint’s SIM card. If you are using your phone overseas where the Sprint network is not available, you have to pay for roaming charges to use your phone for calls, texts, or data when you’re not connected to WiFi.

A locked cellphone usually comes with a disclaimer about using it on other carriers. If you previously used Sprint and unlock your phone through UnlockBase, the phone itself is no longer tied to Sprint or any specific carrier.

Trying to use an unlock app from untrusted sources could brick your phone by sending incorrect commands to your device. Unlocking Sprint phones should be done either through your service provider or through reputable services such as UnlockBase.

According to Sprint’s Unlocking FAQs, your account will be examined for eligibility first. If you are indeed eligible for unlocking, you have to wait 2 days before they unlock the phone for you.

ERROR: Sprint SIM Card Locked. Please Power Cycle

sprint sim card locked error message on phone

This is the same error as the Sprint SIM card has locked and as mentioned earlier, SIM will lock if either the device MEID or SIM ICCID doesn’t match what is on your account. If you would like to fix this, then you can go to your carrier and ask them whether they’ll unlock the phone you’re currently using on their network, especially if it’s a phone that was bought as new as there is nothing wrong with doing so as long as your account with them is in good standing.

To unlock your Sprint phone, you have to prove that you are a customer who is owed a refund or has an account in good standing. You can not unlock a device that is still under contract, and it may take up to 10 days for your handset to be completely unlocked before it can be used on other networks.

It will also apply if you cancel your account with Sprint early by way of cancellation fees. However, as mentioned before, there are now ways around this, so you don’t have to wait any longer than necessary after canceling. Third-party providers such as UnlockBase offer unlocking services at reasonable rates so customers can enjoy their devices without limitations and the warranty they’re entitled to.

Fix Sprint SIM card locked error through UnlockBase

If you are not eligible for unlocking through Sprint, you may use the UnlockBase service. Unlocking your device with us will not break your device’s warranty if it’s still covered, and you don’t have to go through complex processes to get it done.

To unlock Apple devices such as iPhones and iPad, all we need would be your IMEI or the phone’s serial number. We also need just your IMEI number to unlock any type of Android phone.


You should know that if your account isn’t in good standing or you haven’t paid off the remainder of what you owe for the device, Sprint won’t grant your request for an unlocking code.

Unlocking Sprint phones can be done straight from the manufacturer or service providers since they know how these devices work. We hope the information mentioned above gave you an idea of how to fix the Sprint sim card locked issue.

Wondering if you have a blacklisted iPhone? Unsure if you could use or sell it? If you’re stuck with a blacklisted iPhone, don’t worry, we’ll help you figure out how to activate and unlock it in this article.

We’ll discuss how to know if you own a blacklisted iPhone, how to unlock it, and how to sell it legally.

What exactly is a blacklisted iPhone?

A blacklisted iPhone is an iPhone that has been reported as stolen, lost, or outside of the carrier’s coverage area. There are only two reasons why an iPhone is blacklisted: (1) it was reported lost or stolen, and (2) it was canceled due to non-payment. With the first one, you’re likely stuck with an illegally sold iPhone that you can’t use, but if your case is the latter, then there’s definitely a way to use the iPhone again.

Who controls the blacklist?

You might believe that Apple can blacklist an iPhone, but only the wireless carriers are in charge of doing so. Wireless carriers create their databases using the iPhone’s IMEI (International Mobile Equipment Identity) number. A stolen or lost iPhone can result in the device being placed on the blacklist using this unique IMEI or serial number.

And as earlier mentioned, blacklisting can also happen if the owner of a device is unable to pay their contract or if it was acquired fraudulently.

How to Know if Your iPhone is Blacklisted

How do you know whether or not you have a blacklisted iPhone if you don’t know its origin? An easy way to find out whether your iPhone is blacklisted is by purchasing an IMEI check or Apple Network Check (GSX). We offer this service and you can get the results in as fast as 5 minutes.

Through our Apple Network Check, you will know your iPhone’s complete origin details such as the carrier/network and country where it came from. And you will need this information, later on, to proceed with the unlock process.

Suppose you receive confirmation that there isn’t anything wrong with your iPhone, then great! But what should happen when your device comes back as being on the blacklist? You don’t have to worry because there are ways around this.

How to activate or unlock a blacklisted iPhone?

If there is an issue such as someone reporting the phone lost/stolen, any wireless company won’t activate your device. And although we can unlock blacklisted iPhones, we don’t do it for lost or stolen ones.

There are two parts to activating and unlocking a blacklisted iPhone: (1) we get your iPhone’s origin information, and (2) we unlock it remotely using its IMEI.

In order for us to know whether your device can be unlocked, we need to know the ‘Blacklist Status’ and ‘Current Owner Info’ from Apple’s database, and it is something that our Apple GSX Check Service can do for you.

To permanently unlock your iPhone, all we need is the iPhone’s carrier and country of origin, and the IMEI number. Once it is unlocked, you can use your phone on any carrier that supports it!

How to Sell Blacklisted iPhone Legally

Selling an iPhone that is blacklisted can be a tough decision to make, especially since it has the potential of coming back on you in some way. If your device is still under warranty, Apple may refuse to service it if they find out you are the current owner, but what about when this isn’t an option? Don’t worry because you still have options!

One thing worth noting here is that while iPhones are typically sold through third-party channels (such as eBay or Craigslist), certain services are available that will allow you to sell your phone directly to them without having any issues with blacklisting. These companies specialize in buying used devices and reselling them at retail prices for profit, so they don’t care whether or not yours is blacklisted-they just want to sell it quickly.

While there are many reputable services out there, be sure that you do your research before committing any transactions so you can avoid being scammed. Always check the company’s background and customer reviews online if possible and their refund policy if things don’t go according to plan.

For this service provider to purchase your device from you without issues, they will usually need more information than what is provided on an IMEI number alone. In some cases, all that may be needed is a photo or scan of both sides of the phone and its serial or IMEI number, which will allow them to determine whether or not the iPhone can be legally sold.


Purchasing a used iPhone is an excellent option to save money on the most recent Apple devices. Even though your iPhone is blacklisted, it doesn’t mean that you can’t use it. Blacklist removal services are sought by people who want to use an iPhone that is blacklisted but there’s no guarantee.

If you can’t unlock it or want to save the effort, you can still sell the locked iPhone. However, you won’t make as much cash from a locked iPhone compared to an unlocked one.

You are here because you got a new iPhone but can’t use it. The moment you try to enter a sim card it keeps saying ‘Sim not valid’  or ‘Sim not supported, and now you’re stuck with a phone that you can’t use at all, at least for voice calling. In this article, we’ll walk you through why you get this error and the possible ways and workarounds on how to fix this kind of error. 

Sim not supported iphone error – what does it mean? 

Sim not supported iPhone error only appears for two reasons: (1) your phone is locked to its carrier, or (2) you’re having software issues. But the most common reason would be the first one, your phone is locked to its carrier. 

You might be wondering, ‘why would my carrier lock my device, when I already paid for it?’ This is a common misconception among many postpaid users, but your phone is locked to them simply because they want you to keep using their service whilst your phone is still not fully paid.

When you get a new iPhone from T-Mobile, AT&T, or any other service provider for postpaid service, you are essentially paying for the subsidized price of the phone added to your monthly bill. 

When you are done paying your phone, it will NOT be automatically unlocked, you have to request from your service provider/carrier that you want to use the phone elsewhere or you’re moving to another network. Some carriers offer it free, but in most cases, you still have to pay them a service fee for unlocking your phone. 

On the other hand, if the phone is still locked into them (usually 24-36 months), they might deny your request for unlocking unless of course, you are willing to pay for the remaining subsidized price of the phone. 

The only way to know whether or not the ‘sim not valid’ or ‘sim not supported’ error on your phone is caused by your carrier is to check its settings. Here’s how to do it: 

Go to Settings > About > Carrier Lock > No SIM restrictions 

If that is what it says then your phone is already unlocked- otherwise, it is still locked to its carrier.

Unlocked iPhone: How To Bypass Sim Not Supported Error 

The ‘sim invalid’ error on already unlocked iPhones is easier to deal with because the issue can be easily solved without much technical knowledge. Oftentimes, the issue can be solved by a simple iOS update or a restart.

Here are the possible fixes you can do:

  • Confirm if your SIM card is activated by your new carrier.

If it’s not activated on their end, that’s the reason why you get that error. Make sure to have the SIM card and your phone number activated on your new carrier.

  • If it is activated on their end, try to restart your iPhone.
  • If that doesn’t work, try to eject and re-inject the sim card on your iPhone.
  • Try calling emergency numbers on it.
  • Try updating your iPhone’s iOS.

Although it is rare, bugs on older iOS versions could be the reason why you are getting that error on your phone. But it is always a standard procedure in troubleshooting to update the iOS.

  • Try to reset all settings.

Some changes in the firmware or a possible hiccup in the software could be the reason why your phone is not accepting the SIM card. Resetting the settings on your iPhone will refresh the system settings

Fix SIM not supported iphone error by unlock

The easiest, most convenient way for you to get it unlocked is through an unlocking service provider like UnlockBase. No codes, no device settings tweaks, and no hassle. Our process of unlocking iPhones only needs its IMEI number.

The process does NOT involve you tweaking some settings or even taking out multiple sim cards. We’ll show you how it’s done below. 

Unlock an iPhone with Unknown Carrier

One of our qualifying questions before unlocking a phone is the carrier name and location. If you are not sure where your iPhone came from, you have to check first if it’s ‘ clean ‘ and not blacklisted/stolen. We do not unlock blacklisted and stolen iPhones. To get your iPhone’s full data instantly you may try our trusted Apple Network Check. All we need is your IMEI. 

The easiest way to get the IMEI is to simply dial *#06#

Unlock an iPhone with Known Carrier

If you already know where your phone came from or its original carrier/network service provider, then you’re ready for the unlock process. 

Step 1: Go to https://www.unlockbase.com/unlock-phone/iphone/

Choose Apple, then choose your iPhone’s model number. 

Step 2: Next, enter your iPhone’s IMEI number and Email. Then choose the country and the carrier where it came from.


Step 3: Wait for an email confirmation from us that your phone is unlocked. 

Step 4: And finally, once you receive the confirmation email, all you have to do is ensure you have the latest versions of iOS and iTunes on your phone. Insert a compatible sim card from the carrier you want to use, and then connect your phone to your computer using its original USB cable. 

Launch iTunes and wait for your iPhone to be detected by it, disconnect and reconnect after 10 seconds and voila! Your iPhone is now unlocked!

Released August last year, the Samsung Galaxy Note20 Ultra 5G is aimed at serving a very specific target market. Perfect for those who take ‘work’ wherever they go or for content creators who record or make content in the most random moments, this phablet is everything you need for a portable ‘studio’.

If you’re considering buying this specific model from the Samsung cosmos, let’s take a look and unlock its features.

Top-level Overview


  • The brightest AMOLED Screen so far 
  • Sharp Space Zoom cameras 
  • Long battery life 
  • Powerful new features 
  • The gaming experience is amazing
  • The S Pen has become much more intuitive


  • Very expensive 
  • Less memory capacity compared to previous Note models 
  • The curved display is aesthetically pleasing but annoying at times. 
  • Fingerprint resistant finish 
  • The camera bulges too much and it’s too bulky

Design and Build Quality

What you’ll like: 

If you’re buying a Note for the first time, you’ll definitely fall in love with the Note20 Ultra. It is a beautiful phablet (phone and tablet) with a matte bronze finish standing 6.9 inches tall. The weight of the phone is just about right, it is substantial enough to assert itself as a premium flagship device, but not too heavy that it feels like it’s made with cheap materials. 

The whole phone is made of Gorilla Glass both front and back and has a stainless steel frame. It is fingerprint resistant so you don’t have no need to wipe it too often. 

And if you’re feeling like taking your phone underwater to take incredible beach pictures, have no fear, because this flagship can stay submerged in up to 1.5m underwater for 30 minutes (IP68 dust/water resistant ). For sure you’ll have been able to take a lot of pictures by then.

What you won’t like: 

Design-wise, there are many things you wouldn’t like about the Note20 if you were to compare it with other flagships. Just like its predecessors, the Note20 Ultra has a curved display, although Samsung has managed to keep the apps away from the edges, it does cause accidental screen taps. 

The cameras at the back bulge off the back too much that the phone can’t lay flat on a surface. It makes the phone rock when you lay it down and because they hit the surface first, they are prone to breakage. Good to remember if you’re a butterfinger. 

It does make up for its 5X optical zoom ability which is very stable even up to 20x. You can zoom up to 50x and still get a decent photo, but it might be a bit too shaky for some. And if you’re not a leftie, you probably wouldn’t appreciate how they have moved the S-pen to the left hand side in this series. 

Lastly, this flagship is very, very expensive. From T-Mobile, the full price is $1299.99 when bought

The Note20 Ultra has an advanced chipset and operating system making it one of the fastest phones today. 

What’s in the box:


The cameras at the back may look unsightly but it captures way better than the Note20 5G. It has a dedicated autofocus sensor at the back that helps ensure your images are steady and sharp even when you zoom in up to 50x. 

It can be a preference type of issue, but the Note20 Ultra cameras make faces washed out or too ‘filtered’. 

If you’re a filmmaker or video content creator that takes a lot of raw videos, the Pro Video Mode is an absolute treat for you. You have the ability to tweak anything from the exposure to the white balance. Moreover, you can choose your bluetooth earbuds as the audio source so when you’re recording videos or vlogging outside, you can effectively reduce the background noise.

The S-pen.

Whether you’re taking notes or drawing, the S-Pen is your companion for your day-to-day work. It feels natural and smooth, and you will love how it came with new intuitive features. 

Samsung added new air gestures for the S-Pen and it’s a fast shortcut for when you’re in a hurry or multi-tasking between apps. You can even take screenshots you can write on or annotate! 


Whether you play small or play big, the Note20 Ultra is able to keep up with your needs. You can use DeX Mode and play on a 4K TV and you can stream XBox games and play with no lags. 

Aside from gaming, you can cast your Note20 Ultra screen on a TV and open multiple apps. You can also show your whole Note20 Ultra screen on a laptop or PC and be able to take calls, or run multiple apps side by side. 

With its 4500 mAh battery which can last a day on normal use, with music or video streaming, gaming, calling and more. 


In conclusion, we can say that the Samsung Galaxy Note20 Ultra 5G is the ultimate dream phone for content creators who take their craft seriously, and a great phone for multi-taskers who take work everywhere they go. 

Is it worth its hefty price? 

For all the features it offers and the quality of the build, it is every bit worth its thousand dollar price tag. 

Compared to other flagship manufacturers within the same price point, the Note20 Ultra boasts superior features than the rest- moreover, with so many trade-in discounts nowadays, you will still be able to slash off a good amount from the original price making this phablet a steal. 

That’s it for our review of the Samsung Galaxy Note20 Ultra 5G, we hope this helped!
