Before You Go

Cell Phone Use In Baja

If you're using your cell phone in Baja, chances are that you have one of the four main US wireless services: T-Mobile, AT&T (Cingular), Sprint or Verizon. You may have an easier time calling throughout Mexico with T-Mobile or AT&T, since they cover a lot more territory.

All of the major wireless networks will charge you extra to roam internationally, from as little as $0.59 to $1.49 per minute plus a monthly flat fee. More importantly, most plans require you to activate the international roaming service before you even leave the United States. To be safe, it is a good idea to check with your own wireless carrier before you leave for Baja to make sure that your phone has been activated for international roaming.

Once you are in Mexico with a successfully activated phone, you should have no trouble calling either locally or home to the United States.
