It will be blacklisted, and carriers share black list, so once black listed, you won't be able to use it on tmobile.Hello all, I have a VZW Note 3, it's still under my 2 year contract with Verizon. Anyways I am thinking about just not paying my bill and using a tmobile sim. My question is if I don't pay my bill and they blacklist it for non payment can I still use a tmobile sim on it? Also does anyone know if a VZW Galaxy S4 in the same situation can be used on tmobile as well after being blacklisted for nonpayment?
