I bought an unlocked Sprint Galaxy S7 from woot.com. I installed a TMO SIM card and everything works fine except for data.
TMO tech support said it was probably not completely unlocked by Sprint.
Sprint will not unlock it since I don't what phone number (account) the phone was with on Sprint.
A local phone shop will flash it to TMO for $75.
Has anyone heard of this problem (everything works except data)?
Also, if I try to flash it myself, I want to use base android OS. Will this fix my problem?
