If I have a V3C razr from Verizon and my family is switching to T-Mobile, will I be able to use the V3C?

Question

I'm just wondering, about what the difference is in the software. Will my V3C be compatible with T-Mobile who uses V3T? Also, if I want to buy a faceplate for my phone what is the difference in the size? I can find tons of cute faceplates for my V3C, but when I look for V3T there's hardly any.
Thanks a bunch ♥

No. Software on the phone won't matter. The hardware is not compatible between the two carriers. Verizon's phones and network are CDMA, which doesn't use sim cards. T-Mobile's phones and network are GSM, which requires sim cards in order to work. They are two completely different technologies and are not compatible with each other.
