Can I take an unlocked phone from TMobile to Verizon?

more options

From now on have 4 months remaining on TMobile contract w/ 4 phones.

    girlfriend gets NO coverage (not even emergency only calls) on her college campus; phones work in our house about 8% of time. Plan was to sit tight till contract expired and switch to Verizon. But two phones now experiencing problems with keyboard and want to act sooner. Cancellation penalty is $400.
    Can I buy an unlocked phone, use it on TMobile for duration of contract, then bring it to Verizon? i choose this NO.1 S7 phone on www.234buy.com .someone talk about difference in technology between the two, but more current posts speculate that problem may no longer exist. HELP!

Verizon (CDMA) and T-Mobile (GSM )use two entirely different network technology. GSM uses a SIM card where CDMA doesn't; that type of memory is internal and nor removable.

AT&T uses GSM like T-Mobile does, so that's you best alternative.
