The Official Android Mobile Device Unlock App

To make the unlock process easier, the Mobile Device Unlock app had been pre-installed by two major carriers in the US, T- Mobile and MetroPCS. Through this app, we are now able to remotely register any IMEI as “Eligible” in your carrier’s database without the need for an unlock code. However, this only works on compatible devices, please visit list at the bottom.

Good news! Turn around is less than 2 business days!

How does it work?

How to use android official mobile device unlock app

You need not visit any T-Mobile or MetroPCS store to get your device unlocked. The Mobile Device Unlock app allows an unlock request right where you are at the moment.

 

However, please note the following preconditions for us to successfully unlock your device:
1. The Mobile Device Unlock app works only with MetroPCS and T-Mobile devices. Any device from another carrier will not unlock using this process.
2. Make sure your phone is “clean”; not blacklisted nor reported as lost or stolen. We don’t have any blacklist “cleaning” service and there’s no refund if your phone is blacklisted.
3. Before you order, make sure that the error you are getting when trying to use the app for unlocking is, “Unlock Failed: This mobile wireless device is not eligible for unlocking. For Device Unlock eligibility details, please go online or contact Customer Care.
4. If you are getting a different error, please check troubleshooting steps before you order any unlock from us. We will not be able to fulfill any unlock request unless your other phone issues are fixed.
5. Make sure you are ordering the right unlock service for your phone/device, choose your carrier correctly.
6. Make sure your phone can communicate with “Device Unlock App” server BEFORE you make any unlock order from us. If you are getting a “Serving not responding, please try again later” error, it means that your phone isn’t communicating with your carrier’s server. Check troubleshooting steps for more.
7. Make sure your phone is with its original software and IMEI. If you installed a custom software prior to your unlock order, it will not be possible for the app to work. Also, make sure that your phone has the latest software. There’s no refund for unsupported software fault.
8. Before starting the unlock process on your mobile phone, make sure that you have an active 3G/ 4G/ LTE or wifi connection. If your internet connection isn’t reliable, there’s a possibility that the unlock will be unsuccessful. We can’t retract the process, so we need to do it right the first time. There’s no refund for an unreliable internet or data fault.
9. Once you receive an email notification from us, make sure you follow all the necessary instructions or order prerequisites, take note that it varies per carrier, but we always ask everyone to try to unlock their device using the app before proceeding with their order. This way we will know the exact error that you are getting for us to know whether your device can be unlocked with us.
10. If in case, you have not followed all the instructions or have withheld important information from us that caused the unlock process to be unsuccessful, we will be unable to provide any refund.
11. Make sure your device memory is managed properly, and clear all cache.
12. Always restart your device after the unlock process. You’ll have to see a pop up every now and then.

Why should you unlock your phone?

  1. It is legal.
  2. It is free from international charges.
  3. There is no security loss.
  4. You get to fully utilize your phone and enjoy its features.

 

 

Unlocking Phone is Legal

 

“If I would unlock my phone, is it legal?” This particular question has been going around among smartphone users – and some couldn’t even get a decent answer, hence, enduring the restrictions over their phones. Not being able to enjoy the perks that your phone offers may be frustrating especially when you are constantly traveling overseas.

To be able to clarify this matter, here are a few things you should know with regards to unlocking your phone and why you should do so.

 

 

is unlocking my phone legal

Is Unlocking My Phone Legal?

For most users, the common misconception of unlocking phones is that it is purely illegal. Thing is, every three years, the Library of Congress reviews the rules of the Digital Millennium Copyright Act (DMCA) and makes particular exemptions allowed under the rule of law. Way back in 2006, the Library allowed unlocking to be exempted from the DMCA. However, that exemption was short lived until 2012 as the Library did not renew the exemption. The change was due to the reason being the firmware that your phone has is copyrighted and cannot be changed without violating the law.

But that is the history of unlocking being illegal, once.

On 2014, US President Barack Obama signed a law stating that “…each smartphone owner has the right to unlock their devices and use them on other networks,” reversing the previously stated law on unlocking phones. This law comes with a few hoops like AT&T allowing you to unlock your device only when your contract has expired.

 

 

why should I unlock my phone

Why Should I Unlock My Phone?

You may be asking yourself, why should I? For the most part, it isn’t mandatory. However, you could be missing a lot of things if you don’t. To help you with this matter, here are the key reasons why you should unlock your phone.

 

1.  Free from international charges

For most people, the use of unlocking your phone is not to change a network – rather, to be able to use your phone overseas without paying too much. When you purchase from a carrier, the front charge would be lower. However, as you would know, the device will be locked by that same carrier and will only work on their network. Furthermore, when you travel overseas, you will need to pay that particular carrier with the international charges so you can use your phone. Meaning, replacing your existing SIM card with another wouldn’t work. For this matter, unfortunately, buying a SIM card is much cheaper than paying those charges, and you wouldn’t have any other choice as your device is locked.

 

2.  Change carriers

Being in a contract makes you restricted from availing better deals from a different carrier. While it is true that carriers aren’t all great, they still update their plans to provide better service offers. In such case, you may find the plan that would work best for you in another carrier while you are tied to a contract with another, which means you wouldn’t be able to avail your preferred plan.

 

3.  No security loss

Most times, people worry that unlocking your phone may cause the device to be vulnerable to security issues. However, this is yet another misconception. Unlocking does not affect your phone’s security, jailbreaking does. That’s two different matters – as jailbreaking your smartphone means downloading unauthorized apps which could affect your device’s security, while unlocking means allowing your phone to work with another service provider.

 

 

Key Takeaway

Unlocking your phone simply means a right – a right to use your phone with another service provider, especially when your device is not being fully utilized due to being locked. Given this point, these fairly good reasons, and the fact that unlocking is legal, why should you not?

Mobile Device Unlock App (Android) - Troubleshooting

Device Unlock is an Android app that allows you to request and apply a mobile device unlock directly from the device.

When your phone is locked with “Mobile Device Unlock” it’s totally useless to order an unlock code.
