MTX Connect

A common headache for a small business sending two or three people on the same trip, or one employee carrying both a phone and a mobile hotspot, is ending up with separate data plans that can't share an allowance. MTX Connect, based in Bettembourg, Luxembourg, and operating since roughly 2012, addresses that directly by letting a single prepaid balance cover both a physical SIM and an eSIM at once, so unused data on one device is still available to the other.

Coverage runs to 160-plus countries with Europe as its clear strength, sold as fixed-GB packages from 350MB up to 10GB with validity from 1 to 365 days, priced from around €3.80. On top of the base data plan, an optional add-on called MTX Number, priced around €60 a year, provides a real phone number for calls and texts, useful for a small team that wants a consistent way to reach each other or clients while traveling. Support hours have drawn some recent criticism in customer reviews, worth checking against your own timezone needs. It's a reasonable pick for a small team or a two-device traveler who wants pooled data over separate individual plans.
