Is there another service provider with prepay that I can use with this phone? I'm out of contract very soon and Verizon has been terrible and expensive for me.
No.
Verizon's 4S is locked and can only be unlocked for international gsm use.
Not domestic gsm carriers.
I remember my Verizon BB 9930 was a world phone like the 4S and I was able to unlock it and toss in a TM sim and I was on their network, but it was edge. The 4S also has this capability.
What your bb9930 or any other cellphone can do is not relevant to this question.
But anyway, you don't have to believe me. Just go for it. Put a TM sim in and see how far you get![]()
You can use a gevey sim to get on TM. Also if your phone is jailbroken you can edit some plist files and disable the CDMA radio so it always defaults to the Gsm.
It's not easy to get it to work on TM, but its not impossible either.
