Thanks everybody for the comments and info. When she was on Verizon there was no charge, She did call US Cellular and they were less than sympathic. But knowing that Sprint and Tracfone also work in San Juan will give us some options and bargining power when she returns home. We will be visiting the store, I sure hope it is ignorance and not out and out lying, we shall see. How they respond may well determine if she returns to Verizon or tries Sprint or tracfone. Good tip to look at coverage at the web site, we didn't think of that just took their word for it. We will be checking the web this time.
Love this site. All kinds of good information here
