What is a good sim card that you can use on an Unlocked Iphone 4S?

When i say good i mean one that has fast internet and that gets good service most of the time because right now I have a T-mobile sim card on my Unlocked Iphone 4s and I don't like that service because the internet is slow most of the time and I loose service most of the time.

Net10 and Straight Talk. Net10 and Straight Talk use AT&T and T-Mobile towers for service with the bring your own phone program. So you have a 50/50 chance of having T-Mobile service under Net10 or Straight Talk.

  • Can you use a regular Straight Talk SIM card in an unlocked AT&T iPhone 4? So I have an unlocked iphone 4 that has GSM and all that jazz that you need to be able to utilize striahgt talks phone services. My problem is is that I knew I needed a Straight Talk sim card to put in the iphone. I went online on Straight Talks website and selected the simcard they had available. Little did I know that apparently I need a micro sim and the one they gave me is a regular sim I'm guessing since it's too big to fit. My question is, can I cut the sim card and use it?
