Device Unlock is an Android app that allows you to request and apply a mobile device unlock directly from the device. This allows you to automatically apply Mobile Device Unlock to the device without using a manual code. When your phone is locked with “Mobile Device Unlock” it’s totally useless to order an unlock code.

Only supported devices (see below) may download the app or have it pre-installed. Supported devices may download the app from: Google Play.

It’s very important to order the unlock service of your Cell Phone using the correct service.

How to apply a “Mobile Device Unlock”

1. From that Application list, tap Device Unlock.
2. Tap Continue.
3. Choose the desired device unlock type: Permanent Unlock
4. If successful, restart the device to apply the settings.

Note: If you do not restart the device, you will have a persistent alert in the notification tray.

Troubleshooting “Mobile Device Unlock” app

1. Check that you have an active data connection.
2. Clear the application cache.
3. Check that the device memory is properly managed.
4. Restart the device and try again.

If you receive an error, review the following table for troubleshooting:

1. Make sure you use the original Stock ROM (no custom Firmware like CyanogenMod, or Unbranded ROM).
2. Make sure you’re using the latest version of Firmware for your Cell Phone.
3. Finally (after upgrade) perform a Hard Reset on your Cell Phone.
4. Turn off 3G/LTE and force the use of a local WiFi Hotspot.
5. Make sure you use home Wifi (and not a public/company WiFi since they might limit somehow your internet usage).

Even on a quiet day here at UnlockBase we receive around 600 emails asking a wide variety of questions about the many aspects of unlocking cellphones. A question that has been asked a lot lately is what is the difference between Android FRP Lock and Samsung Reactivation Lock? Well, many of the most recent Android Phones including models from Samsung, HTC, and Sony can become stuck on activation screen requesting for your ID and password, while others are requesting your Google Account. Samsung phones will ask for a Reactivation Lock ID & password, so that people can be identified along the same lines as apple iCloud Lock. To clarify things, here we provide detailed information on the difference between the two.

What is Factory Reset Protection (FRP) Lock ?

Android Factory Reset Protection (FRP) is a new feature designed to protect your device. It has been added to several Samsung devices that are running Android OS 5.1 or higher.

This feature enables you to set up your device to prevent other people from using it in the event that it has been reset to factory settings without your permission.  For example, if your device is lost, stolen, flashed, or wiped, only someone with your Google account or screen lock information can perform a factory data reset and use the device.

When a device is factory reset, the device will not be able to be setup without the user entering the Google Account associated with the device (for hard reset) or screen lock information (for reset in Settings menu). It’s essential that you set up a Google account in order to use the FRP feature.  It is also highly recommended that you set a secure screen lock on your device.

What is Reactivation lock and how do I use it on my Samsung?

Similar to FRP, Reactivation lock lets you use your Samsung account to prevent others from activating your device if ever it is lost or stolen. With Reactivation lock turned on, you will be required to enter your Samsung account credentials (sCloud) prior to performing a factory reset on the device, so your Samsung account login should be something you can easily remember.

Every week, no, make that every day, at UnlockBase, we get customers writing in with a variety of problems relating to any number of different cellphones. In this article we look at a problem that occurs most often with Samsung phones but can apply to other Android phones in general. First, to acquaint you with the problem, here is a typical customer complaint:

“We kept getting the ‘Not registered on Network’ message when trying to make calls. Many times the network connection was lost for a while. Then we realized by trying to make a call that for a period of time people were unable to get a hold of us or send text messages. We tried everything to try to resolve the issue, and ultimately we replaced our phones with another Samsung Galaxy S5. Guess what, the issue is still there and we still get ‘Not registered on network’ errors. Is this an Android issue or an Android issue? It’s no surprise that Google said that it’s a T-Mobile issue and not an Android issue. Please help!”

  The ‘not registered on network’ error

This annoying problem is often found in Samsung Galaxy devices,   particularly when users update their Galaxy phone to the latest Android   version and something went wrong. Please take note of the following   models:

• Galaxy S7 Edge
• Galaxy S7
• Galaxy S6 Edge
• Galaxy S6
• Galaxy S5
• Galaxy S4
• Galaxy S3
• Galaxy Note 5
• Galaxy Note 4
• Galaxy Note 3
• Galaxy Note 2

What Does Not Registered on Network Error Mean? 

The reason why you see Not Registered on Network error is because your SIM card is unable to connect to your carrier’s network. And when you can’t connect to the network, you won’t be able to make or receive calls and text messages. Aside from Samsung, this is a common issue among Android phones, regardless of who your carrier is or your phone’s make and model.

What causes Not Registered on Network error?

Based on the customer’s experience above, their device is unable to detect the network and up comes the “Not Registered on Network” message. There are many ways this can happen, and below are the reasons why: 

1. The IMEI number was changed. This usually occurs after getting an update and the device IMEI number (serial number) is changed to “SN 0000″ and it shows that your device SN number has been broken and need to be fixed.
   
   
2. You’re APN or network settings are not properly set up. Another reason is when you try to use the SIM Card from a new Network Provider and your Samsung fails to keep up when you’re trying to switch networks and needs a little help from you involving manually providing the new APN settings / Networks name in order to fix it.
   
   
3. Your device has been blacklisted. Another reason for this error is if unfortunately your device has been Blacklisted, and by that we mean if your phone is reported as “Lost” or “Stolen” in the national blacklist database in your country. In this situation you have no choice but to take the following steps :
   
   
   • Go to the police and report the scam,
     
     
   • Try to get your money back from the seller,
     
     
   • Change the IMEI of your Phone (which is illegal),
     
     
   • Sell your cellphone overseas.
     
     

If the problem was the APN or network settings, the ‘Not registered on network’ error will show itself when you attempt to make a call or text. This occurs because your Service Provider is simply NOT notified of your IMEI number so on the screen you will see “Not registered on Network“. They even have the cheek to supply an OK button for you to press which does nothing to solve your problem at all! Frustrating, but don’t worry, we can solve this issue.

First you should be aware that your phone is already unlocked. It’s not the case that you have to unlock your device in order to remove the ‘Not registered on Network’ error.

For everybody else here are the four ways to fix this problem and finally have use of your cellphone.

Most Android phones are quite simple to navigate.  Best of all, they feature access to a variety of apps that you can use to simply your life.  But what happens if you need to unlock your phone from your network carrier?  The best answer is to contact UnlockBase for an unlock code.  Whether you’re traveling overseas and need your phone unlocked or you simply want to switch carriers, UnlockBase simplifies the process of making your phone compatible with other networks.

“SIM Network Unlock Pin Means” You Need an Unlock Code

When you go to unlock your phone, all you need to do is insert a SIM card from the carrier you want to switch to.  If your phone is locked, it will likely display the message SIM Network Unlock PIN.  This means that you’ll need to buy an unlock code from a reputable service provider.

You’ll Need Your IMEI Number to get an Unlock Code

Keep in mind that you’ll need your phone’s IMEI number to buy the unlock code.  On most phones, you can easily identify your IMEI number by typing *#06# and hitting the send or call button.  You’ll receive a message with the IMEI number.

Unlocking Your Phone is Simple

After giving your IMEI number to an unlock code service provider and receiving the code, you’ll enter it into your phone and hit the unlock button.  It’s as simple as that.  If for some reason the unlock code doesn’t work, this most likely means there have been too many failed attempts.  To overcome this problem, you’ll need to do a full reset on your phone.  You’ll also want to make sure that your new SIM card is valid.  For more information on how to unlock your phone, simply contact us today.

The Takeaway
