from my understanding, Verizon Galaxy s5 comes factory unlocked as well as all other verizon LTE phones, although, my t mobile SIM is not working for the phone, i cannot contact verizon as it is on the blacklist for them, i tested with AT&T SIM and the phone does work for GSM so why doesnt it work for my t mobile sim? is it a faulty SIM? i have contacted samsung and t mobile about this and they were no help
[Q] Verizon S5 not working with T-Mobile SIM
- Thread starter jtd930
- Start date
There's now a IMEI blacklist that of the major U.S. carriers all share (Verizon, AT&T, T-Mobile, Sprint, as well as some regional carriers). That means blacklisted Verizon phones may not work on T-Mobile or AT&T (in the past, it only meant they wouldn't work on Verizon). Perhaps AT&T hasn't updated their system with the most recent info to include the phone you have while T-Mobile has.
There's always a chance that it's something else, but I have no problems with my S5 (which isn't blacklisted anywhere) on T-Mobile's network with an active T-Mobile SIM.
turn off phone insert tmobile sim
press and hold vol UP + home button+ pwr when you see blue recovery text in corner let go of pwr

if nothing happens you may have a broken simslot or your simcard is junky try other simcard before you make this a solid idea tho
