hello, I'm a bit noobish, so sorry if the question is a bit lame. I'm considering getting nexus 4 directly from google. I'm currently on t-mobile pay-as-you-go (prepaid minutes). Will I be able to plug in my sim card from my old phone into the nexus 4? Will I be able to use it as a regular pay-as-you-go phone, without data plan, while being able to use wi-fi? thanks in advance.
