Countries in Worldwide

Malaysia, Bulgaria, Thailand and Greece are where Worldwide eSIM choice is strongest; the region’s vast reach and many island territories leave availability much thinner elsewhere. That can suit an itinerary built around the major markets, but a stop in Tuvalu, for example, may have far fewer options than the label suggests. Availability varies between plans, so check each destination’s country page before relying on a Worldwide package for a multi-country trip.
