Mexican SIM Card

We use the Telcel SIM card and an app called Talkatone it is a free (or paid) VOIP app that works great with Telcel data
it gives you a CND or US phone number to call or text with and you can forward your regular cell phone number to your Talkatone number it will work anywhere you have data or wifi.

Cool! Google Voice is very similar. You get a Canadian or US phone number and can make free calls using WiFi to the US and Canada. There are per minute charges for calls to other countries based on the country. It sounds as if Talkatone is similar, yes? Let's see ... hmmm, there is no mention of other countries and the website says that most Canada and US calls are free while others are "low cost." Bit sketchy.
