Can an ATT LG Optimus G Pro be unlocked and used with Tmobile network?

[AC Question]

Hi, I'm new to this whole device unlocking thing. We are unsatisfied with the cost of ATT & would like to switch to tmobile. 2 of our 3 devices are compatible for sure but I have questions about the LG Optimus G Pro. Can that be unlocked & used on Tmobile's network>?

If it's an AT&T phone, yes it can be. Ask them to unlock it. If they won't, look around for an inexpensive unlocking service.
