Google voice is only in the USA right now. But the next time you visit the USA (if you ever do) use a Wi-Fi connection and sign up for Google voice claiming you live in the USA. Since the service checks where you actually are, you cannot just claim you are in the USA now. Once you go back to Mexico, you will have a USA number you can call from using programs like Groove IP, and the Google voice app to get voice mail, plus to send and receive text as though they were in the USA. I have helped some of my old neighbors set it up so they could keep in contact with their family in Mexico without paying international rates for calls or text. You have to have a pretty fast internet connection for groove IP to work well though.
Not I do not know if have someone you know in the USA now signing up for you then giving you the Google username and password will work or not. Also it was several years ago that I did this for my neighbors. Google may of change it so this does not work anymore. Ask around to see if anyone else has tried it.
I have never been to Mexico but where I live there are many Mexican areas. Good food. Nothing like taco bell, LOL.
