Ubigi

Backed by Transatel, Ubigi reaches 190-plus countries with data, but the voice and SMS bundles with local phone numbers are selective. You'll find this combo available in major markets like the US and France, making it solid for frequent visitors to those regions.

The broad country coverage is the draw here, even if the full voice bundle isn't everywhere. Travelers who hop between many destinations and only occasionally need a local number appreciate the option where it's available.
