In the U.S.A, the main technical barrier which can come when it comes to the unlocking a phone is the difference between GSM and CDMA. Carriers like AT&T and T-Mobile generally operate in GSM network and at the same time carriers like Sprint and Verizon do have a working principle based on GSM standards. Therefore, if you want to switch to Verizon from the T-Mobile, then it won’t be possible. But if you have AT&T and you want to switch to T-Mobile, then it is compatible and you won’t face any kind of major problems.

On the same contrast, it can be said that CDMA phones are more conservative. Because, if you have a Verizon phone and you are looking to switch it to Sprint mobile, then it won’t be possible for you. Therefore, the first thing you have to make sure before switching to another carrier is, your phone is compatible with that carrier.

Apart from the restrictions between GSM and CDMA standards, there are also few technical barriers in switching your carrier. There are few carriers who lock the phones. Therefore, when your phone is locked by a carrier you can’t move to another carrier irrespective of their working principle. For example, if T-Mobile has locked a particular phone, then you can’t replace the T-Mobile carrier with the AT&T. It does not matter if both of them are GSM phones. At this moment, the T-Mobile phones, only accept the T-Mobile SIM cards and it will reject SIM cards from any other carrier.
