Tello Mobile

Tello Mobile preserves your existing US phone number when traveling internationally, avoiding the hassle of number porting or managing separate lines. You get a monthly allowance of 100 calling minutes, unlimited text messages, and the ability to place calls over WiFi when cellular isn't available. The approach lets family and colleagues dial your real number without learning a new contact.

It works best for US residents taking extended trips who want to stay reachable on their home number without expensive international roaming charges. The 100-minute quota suits people who primarily text and use data while abroad, with calls reserved for important conversations. WiFi calling bridges gaps in cellular coverage.
