I've been a Verizon user for almost ten years, and I'm almost ready to make the jump to do something else. Even though this is probably an easy question, here it is: Is what carrier Straight Talk uses based on the SIM that you buy? For example, I assume if I buy an AT&T Straight Talk micro-SIM card, then I will be running of AT&Ts towers, right? T-Mobile is horrible in my area and I just wanted to make sure I get to pick which towers I'm running off of.
Thanks in advance.
