Who I have the same questioned this topic

I am going to Costa Rica. I have a Samsung S-4 with a U.S. number and U.S. billing address.  I am looking at Verizon's International Plans, specifically "International Travel 100 Talk, Text, and Data."   While in Costa Rica, I want to be able to phone a local number, like a restaurant.   Would this be treated as a  local call or an international call?

I also want to call my family back in the US. Will this type of call be a local call or an international call?

Thank you, Nancyoscar
