T-Mobile phones can unlock 

SamKEY TMO is special software for Unlock T-Mobile, MetroPCS, Verizon and Sprint operator locked phones!
Which do NOT ASKING FOR NETWORK UNLOCK CODE, and just say: Invalid SIM Card (APP UNLOCK)

Few major clarifications:

* Only USB cable is required for unlock
* This solution makes Phone PERMANENT UNLOCK so even after updating firmware also the phone will stay unlocked
* Software will be locked on one pc with fingerprint
* Software will work only when you have the phone in hand (means USB sharing will not work)

Supported Models so far
G930T, G930T1, G930P, G930V
G935T, G935T1, G935P, G935V
