Most cell phones come locked to a specific network. For instance, if you bought your phone from T-Mobile, it will only work on T-Mobile’s network. The same goes for the other cell phone carriers. Once you get it unlocked, you can take your device to any carrier of your choice (assuming its compatible). This guide will walk you through the unlocking process.

Eligibility Requirements

T-Mobile will give you the needed codes to unlock your phone for free. However, there are a few criteria you need to meet before they give you the code:

  • You haven’t requested more than two unlock codes on the same line in one year. T-Mobile will only allow two devices per phone line to be unlocked each year.

In addition to this list, there is another set of eligibility requirements depending on the type of phone you have.

If you’re in the military with an account in good standing, you will receive a T-Mobile unlock code with proof of deployment. There may also be exceptions to unlock your phone if you have a business or government account. Those are decided on a case-by-case basis and you’ll need to contact T-Mobile customer service for more information.

If you aren’t a T-Mobile customer but have a network phone, you can request a T-Mobile unlock code through customer service. However, T-Mobile won’t unlock the phone if it has been reported lost or stolen.

When you call T-Mobile and get the unlock code, they will also give you directions to input the code. Once you do that your phone should be unlocked.

You will know your phone is unlocked because T-Mobile will follow up in 48 hours with a confirmation email. After that email, you may have to wait another 24 hours for your phone to be officially unlocked. To make sure it’s unlocked, you can insert a SIM card from another carrier. If you receive service through that card, your phone is unlocked.
