While I wait for a new phone from TMobile - back ordered with a month wait - I am going to buy a cheap junk Samsung S4 and try to run that for a few weeks on TMobile's network, until the real phone arrives. The phone I purchased is a Verizon locked phone. How do I convert a Verizon Samsung S4 to be either unlocked or alternately to program it with an OS that is locked to TMobile? Which is likely to be more reliable with a TMobile SIM card?
Can't you force a firmware version onto the phone that will change it to either unlocked or TMobile?

The inability to use TMobile frequencies is more problematic.

What would be a very cheap phone I could buy used and use perfectly with TMobile's network? I am going to be using this phone under one month.
You really need to get a carrier unlocked phone instead for this, or just get carrier-locked T-Mobile model.
Flashing a different carrier's firmware only occasionally works, and when it does there's an added issue on whether everything will be fully functional.
