I want to buy a mobile router wifi hotspot so my husband can use his iPad in Puerto Vallarta. (Our hotel has very expensive, unreliable wifi.) Telcel lists two on their website but no prices. Can anyone suggest a good place to buy this (along with a chunk of data for a two week period)? Does anyone have an idea of what they cost in Puerto Vallarta? I also have the option of buying an unlocked one in the U.S. and just getting a sim card in Mexico. I'm not a techie person and will need help setting up either option and my Spanish is limited.
