If you're going to Todos Santos again, I can tell you that both Telcel and Movistar have service there, with Telcel having better coverage - at least
when I was last there in January. Before switching to Google's ProjectFi network, which has fairly seamless coverage in Mexico, I bought a Telcel SIM
card for my unlocked HTC One phone and it worked well. I'm not sure that's an option for you and your phone, so a cheap phone with a pay-as-you-go
plan might suit your needs best. |
