Diri Mobile Telephone Service

Hola.
I use TelCel amigo sin limite. 200 pesos for 30 days. 3GB data plus unlimited calls anywhere in Mexico, the USA and Canada. More data is available for more pesos, don't know how much
I have never run out of data for my use

That's a pretty darned good deal. Thanks for the tip. May I ask which mobile phone you use with this service? OnePlus (sp?) phones seem to be very popular in Mexico.

If you have a Google account, you can use Google Voice and a Virtual Private Network (VPN) to make calls in the U.S. and Canada using Voice Over Internet Protocol (VOIP) providing your Internet service is not very slow. It works pretty darned well. You can also make international calls for very reasonable rates. Google Voice is still free but they could start charging anytime.
