Are you flying to Mexico City and wondering if you can buy a prepaid SIM card at Mexico City Airport? I recently arrived at Mexico City International Airport and explored the tourist SIM card options myself, including AT&T, Movistar and Telcel.

The short answer is: yes, you can buy a SIM card at Mexico City Airport, but it is not the easiest or most convenient place to get connected. There are some options inside the airport, mostly through convenience stores and small phone shops, but the setup can be confusing if you have to do it yourself.

My recommendation is very clear: if you want to buy a local prepaid SIM card in Mexico, focus on Telcel. AT&T and Movistar can be cheaper, but Telcel has by far the best mobile network in Mexico. For tourists, especially those traveling beyond Mexico City, Telcel is the safest choice.
