How byOne works
Learn what an eSIM is, what you need before you start, and how to get connected with byOne while traveling.
International mobile data, without swapping your SIM
byOne provides prepaid travel eSIM packages for local, regional, and global coverage. Some plans are data-only, while others may include voice or text where supported by the catalogue.
