Actually, no. If you have unlimited calling and unlimited messaging on your plan, you will not be billed additional fees to call or text someone who has a Puerto Rican phone number. That is because Puerto Rican phone numbers are actually considered U.S. phone numbers, as far as Verizon Wireless is concerned.
Thank you for reaching out. We want to make sure that you can stay in touch with your co-worker. Calls and texts to Puerto Rico are part of your domestic calling plan. This means that you will not be charged when you call or text each other. Does this information help?
