Will my iPhone 4 work in Mexico? I have AT&T?

Just curious what will I be able to use and not use.

Yes you have to get it unlocked though, if you get a factory unlock you can change your service but if you call AT&T and ask the to da an international unlock, you can use it on a different SIM card but there are extra charges and fees

Get your iPhone 4 factory unlocked and it will work fine in Mexico as AT&T is GSM and all Mexican carriers are GSM too. Check online for factory unlocking the iPhone 4.

  • Would the iphone 5s work in Mexico? I have an aunt that wants the iphone 5s and she lives in Mexico so I call apple store to see if they have the iphone 5s unlocked and they said that is coming out in a month and I was looking at the tmobile one but I want to know if that one would work in Mexico? Or the Verizon?
  • Will my iPhone work in Mexico? Well my iPhone has been blacklisted by my parents and since its unlocked I was wondering since I'm going to Mexico for vacation would it work there with a Telcel sim since its only blacklisted in the US
  • Will my iPhone work in Mexico with Telcel Sim? Well my iPhone has been blacklisted by my parents and since its unlocked I was wondering since I'm going to Mexico for vacation would it work there with a Telcel sim (It's an AT&T iPhone) or is it blacklisted by AT&T globally?
  • Will my iPhone 4s work in Mexico? I understand it is a 2g network there. I'm staying there for 5 months and will need my phone to contact people. Should I not bother with the 4s and just buy a phone there?
