Existing plan

[DEVO3386]

I thought that my wife and I have a plan that enables us to have talk, text and data anywhere in North America?  I literally was just in Florida for one week and had data while driving to Florida but had issues texting friends and family even with us all having I phones, after a few days in Florida I lost my data and was not able to text anyone or get any data?  I could not use Google Maps and had no idea where I was going as my friends are less tech savy than I am!  My calling option appeared to work as was able to call my wife but I literally only used it to call once.  Can you verify the plan that we have and why I wasn't able to get data and texting while in Florida?

My big concern is that we are leaving for Mexico Saturday morning and absolutely need data, texting and calling while there!

PM has 3 roaming providers in US and 3 in Mexico 

While the phone usually can sort it out for you can choose the best network, but you might need to manually try others if one failed 

In US, T-Mobile or AT&T or Verizon

In Mex, AT&T or Telcel or Movistar 

So, when it has problem, change network mode to Manual and try each one

Of course, remember to turn on Roaming Data on your phone
