Please forgive me if this has been asked already multiple times, but I can't seem to find any recent answers that help.
I currently have Verizon for service and my wife and I each have the Verizon S3 phones.
A few days ago she had gone to the Tmobile website and saw the cheaper rates and ordered 2 sim cards for Tmobile service and signed up to have our numbers ported. Since then, our phones are not working and Verizon says once they get notified that you are cancelling your account, they automatically shut your phones off and then completely cancel you once the billing period is up, leaving us with no phones at all (we have no landline).
Our Sim cards are set to be delivered Tuesday and I need to know what, if any can be done to at the very least be able to get voice service with the Tmobile cards.
I can find older posts from 2013 about how to dial *#197328640# and go through an unlock procedure, but since my phone was bought August 2013 and now has Android 4.3 running I am also finding answers of people saying basically if you have 4.3 you are out of luck.
I am not new to flashing Roms or anything, I just need to be pointed in the right direction on what can and can't be done, like do I need to load a 4.1 Rom? I'm trying to at least have voice service until I can buy Tmobile phones if needed.
Thank you in advance for any information that can help.
