New rules: How to unlock your smartphone

Preston Gralla | Feb. 16, 2015
Computerworld has put together everything you need to know about unlocking your phone, including how to find out if your phone is eligible for unlocking, how to unlock it with the major carriers, and how to move your phone from one carrier to another.

So before unlocking, check with your new carrier and make sure your phone will work with it.

You won't pay a cent for the service...

How much will this cost you? Nothing — you should pay zilch. The FCC has banned service providers from charging for unlocking your phone.

...although there are exceptions

If you're not a customer of the carrier that the phone is locked to, you might be charged a fee. You'll have to check with the carrier for details. Also, if you use a third-party unlocking service such as a kiosk, it might charge you a fee.

Make sure you understand how to unlock your phone

The exact process of unlocking phones can vary from carrier to carrier. In some instances, you may be provided with an unlock code, or it can be done with a software update. Some providers might require that you come to a store to unlock your phone, while others will do it remotely.

Here are the specifics for the four major carriers:


With AT&T, you fill out a Web form on the company's Consumer Device Unlock Portal to ask that your phone be unlocked. Make sure that you have your phone's IMEI number (a 15-digit number). How you find that number can vary from model to model, but on just about any phone, you can find it by typing in this sequence: *#06#. You probably won't have to tap the Send or Call button. The number will likely simply appear.

You can unlock your device from Sprint either by calling 888-211-4727 or via a Web chat. In some instances, for "devices launched after February 2015," in Sprint's words, your phone will be automatically unlocked as soon as it's eligible. Check out Sprint's general information about its unlocking policy and FAQ for more details.


Call 877-746-0909 or launch a Web chat to do it. For more information about unlocking your phone on T-Mobile, check out its unlock policy and details about how to go about unlocking.

Verizon Wireless

If you have a Verizon phone, it may already be unlocked. Verizon's online documentation for unlocking says that it doesn't lock most of its phones or tablets. It notes, "We do not lock our 4G LTE devices, and no code is needed to program them for use with another carrier. We do not lock our 3G devices, other than our non-iPhone Global Ready 3G phones." If you do have a Verizon phone that's locked, call 800-711-8300 and ask for a SIM unlock.
