If the phone can be unlocked successfully (Not directly from Verizon), then you can use on any gsm network.
Any GSM network other than those in the good ol' USA... those are LOCKED even if the GSM side of a Verizon iPhone has been unlocked. One could get a GSM sim from a provider in Canada or Mexico and "roam" in the US on those providers' roaming partners.
Your wrong and right. I never asked about roaming to a diffrent country. My question swas if I could use the 4s with tmobile.
To answer my own question i did get it working. i unlocked my phone and put a tmobile sim card in my 4s and it worked. Only thing I had to do is go into settings-network and swith it over to tmobile. I cant use both networks at once
Problem solved close thread
Can you tell me how to change the network-setting? I couldn't find it. Thanks.
I have a Verizon iPhone 4s 5.1.1 bsbnd 2.0.12, right. Well I unlocked with Gevey Ultra S CDMA/WCDMA, and everything is working perfect, except the pic messaging and Cellular Data. How did you get them to work? I even followed this link, 4 times all the way through!
NOTE: Also, when turning on the phone after reboot, it searches for signal, comes up and says you been unlocked like normal then it picks up AT&T instead of T Mobile, and if you turn off Auto Network under Carrier, next time I reboot, Auto switches back on
Alright folks! In order to put a Sprint/Verizon 4s on Tmobile, you simply get a sim unlock chip (I used AIO unlock because it is updatable). There are others like GPP, Gevey Sim, etc.. They run 18-30 USD, and it is simple as buy insert and viola. (some chips require programing like mine. I am able to get 2g and 3g i believe in spots!
