I have just signed up with the Simple Choice North America Plan,and I will be using my phone mostly in the Puerto Vallarta area. Which Mexican companies (all owned by Slim, so does it really matter - yes, because they all have their own cell towers) does T-Mobile partner with in order for their clients to have coverage here in Mexico?

The primary roaming partner seems to be Telcel but people have gotten Movistar to work if Telcel failed. Always a good idea to have a backup plan when traveling internationally.
