If you are Verizon user traveling to Puerto Rico, you will not have cellular service. I'm in the most populated city, San Juan. I've only been able to text, use data, etc when I have access to my hotel's wifi. T-mobile and AT&T users have strong coverage without additional fees. I contacted Vetixon prior to my trip and they ensured me I would not have additional roaming charges and that coverage would be strong. Verizon cellular coverage maps indicate that coverage is strong throughout much of the island. This is inaccurate. Your phone will indicate that you have "Exteneded" coverage (essentially you are borrowing service from another provider), but you will not have service.
