Best Data Worldwide

My wife and I do a lot of foreign vacations around Europe, Mexico and the eastern Med. In the past high speed data has always been spotty. The combination of convenience (virtual SIM card) and low data package cost here has changed all that. This cruise we visited 5 countries around the Med and had flawless high speed internet in every port. I’ll never travel without it again!
