Wim

Wim is the digital eSIM brand from AT&T, offering regional plans across 170+ countries with a focus on frictionless activation via QR code. Since they're backed by a major US carrier, domestic coverage in North America integrates cleanly, and you get the reliability assurances that come with a carrier-run service rather than a third-party MVNO.

Best for AT&T customers or US travelers who want a single eSIM handling both domestic and regional international needs. Wim's carrier pedigree and long history since 2018 appeal to users who prefer dealing with a known brand rather than smaller regional providers.
