Ok this is kind of a stupid question, but here goes. I just got tmobile for the first time with a Nokia Lumia 521. If I buy a HTC One and put my sim card in it, will everything be set and ready?
I have a 4g plan and everything. I'm not wondering about photos, music and stuff, just if my account will work simplly by putting my SIM card in another phone (specifically the HTC one)
