Navegator: At one time you had to have a residence and pay a big up front fee. No longer. Many RV'rs that live in parks have a phone line. We had the first phone in an RV park. BUT I had to pay about $200 up front. I only got that line as I was a Telmx shareholder and my broker had me send a letter to Carlos Slim. Of course he never saw the letter but one of his underlings contacted the head of Telmex in Sonora. They even put in a pole in front of our RV space! I tried to get the Internet en Su Casa service. It is great. But you need to sign a 2 year contract and they want a TP or RP. I gave up but may return and try to get them to accept my FMM and a copy of my Telmex bill. The rules are not the same everywhere. I have a Telcel Amiga phone and never showed any ID. Others have said they needed proof of a residence. Google that Internet en Su Casa. They state that after you use so much data they throttle the speed but users tell me they can still stream. At 399 pesos a month it is a bargain.
