Can I use my iPhone 4s in Mexico?

My plan it AT&T and my sister doesn't want to get that thing where you pay to use internet or something.So I was wondering, can I use safari/tumblr/Facebook on my phone without it? I /think/ I remember using it two years ago when I went but I can't be sure. And I already know it will add to the bill, but again, can I use those apps and the internet on my phone there?

Technically you can but like you said, you would be charged money. I used to go to Mexico with my phone and I'd get charged a lot, so I turned off roaming on the settings. I didn't have AT&T but it seems like you wouldn't get service over there.Therefore, you can't use those apps unless you want to be charged money or if you connect to Wi-Fi there.

Turn Cellular Data and and roaming settings off.

This makes it a Wi-Fi only device so you can use Safari, iMessage, Facetime, web based stuff only that way. No big bills. Best luck.

  • Will Verizon charge me more if I use my iPhone in Mexico? I live in the US, but will be traveling to Mexico within the next month. Will Verizon charge me if I go onto Twitter or Instagram or Facebook while in Mexico?
  • 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?
  • Will my iPhone 4 (Verizon) work in Mexico? I have an iPhone 4 and Verizon service. I will be going to Mexico soon on vacation. The guy at the Verizon store told me my phone won't work there because it doesn't have a sim card? And that I would have to upgrade to an iPhone 5. I called Verizon and they told me the phone WOULD work in Mexico. Does anyone have any experience using an iPhone 4 through Verizon in Mexico?
