Buying a Mexican SIM Card

Last year I bought a Telcel Amigo plan SIM at the Oxxo store at the airport in Mexico City. Popped it in and it worked immediately. I think that I paid C$15 for 5 GB. Dirt cheap.

I've been using Telcel Amigo for years. It is inexpensive. You can call anywhere in between Mexico, Canada and the USA for as long as you want for no extra fees. I have never run out of data but If you are a heavy data user you can add more for a nominal fee. The only drawback that I can see is if you are a heavy phone user and you are in Canada or the USA , return calls are charged long distance rates. You can get around that by not accepting the call, but call them back immediately. Makes you wonder how one of the richest men in the world, Carlos Sim can charge so little for a wonderful plan when all the Canadian and USA firms are charging a fortune especially for roaming fees.
