Can i use H2O wireless on iphone 5 from AT&T?

I just got iphone 5 and want to use my h2o wireless sim card on the iphone but the sim card for iphone 5 is really small compared to h2o wireless. Anyway to shrink the sim card? Remember h2o wireless sims work on at&t phones! Now i have iphone 3gs locked for at&t but use h2o wireless

Go to some store they are gonna cut it for you just for $5

You have to cut your SIM. You can buy SIM cutters but it's quicker and cheaper to do it yourself. You can download and print SIM templates and trace them prior to cutting. Use VERY sharp scissors.

  • Will my AT&T iPhone LOCKED work for h2o? This is my second time asking this question! And I have not gotten the answers that I'm looking for. I have a AT&T iPhone 4.It is running IOS 6.It is not unlocked to other phone companies. I know that I have to unlock it to use simple mobile. But what about h2o do I have to unlock it? Or can I just pop the sim card in & call it a day?
  • Verizon Wireless vs Cricket Wireless? On Friday I'm going to get the iPhone 5 and I have an option between those two carriers. So which is better. Please give information about both.
  • Sprint iPhone on h2o, simple mobile? Is it possible to have h2o service running on my sprint iPhone 4s? Or even simple mobile, virgin mobile, straight talk, or anything else? My phone isn't jail broken and not unlocked. Can I still have any of these services? If so, how can I go about getting this done?
  • Is H2O wireless a good company? Will it work on a unlocked iphone 5c? I'm trying to get an unlocked iphone 5c, i have metro pcs right now but they are service is so bad i want to switch but i can't afford a good company like ATT or Verizon. I heard a lot of good things about H2O but i don't want to waste my money, you know? I have unlimited minutes, texting and data right now with metro can i get the same with h2o? I use my phone A LOT so i need something that works well for me Please Help
