Getting a smartphone unlocked has traditionally been a frustrating and tedious process that usually begins with a call to your carrier and ends with either a lengthy support call that involves delving deep into the settings on your device… or more often, a trip in to a store to have it done for you. Thankfully, T-Mobile is pioneering a new way of doing things: self-serve and simple by way of using an app on your smartphone.
There aren’t a lot of details known yet regarding exactly how the app works, but the understanding is that you can request and apply an unlock code that can then be used directly on your device. It also appears that there are two types of unlocks: temporary (good for overseas trips) and permanent (available once your device is paid for in full).
Getting excited for this app may be a bit premature as it only works on a limited number of T-Mobile phones, but try to think of it more as a proof of concept that is likely to be adopted by all carriers for all phones in time.
