We can understand your concern regarding the notification of charges to Puerto Rico. Please allow us the opportunity to look into this. Can you please send us a Private Message?
The issue is with Wi-Fi calling. I get that message too and I was told to just ignore it. Doesn't seem like a great solution..... Apparnetly there are some really old plans that charge long distance when calling to PR but any other plan shouldn't including current ones.
Our goal is to ensure that you get the best and most accurate answer about your WiFi Calling concerns (https://www.verizon.com/support/wifi-calling-faqs/), chrispr. You are correct about how the plan you have may impact your calling rates. What is the name of our calling plan? We'll be happy to check this issue further for you. -Antonio
