yaySIM does not offer an Isle of Man eSIM plan that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from yaySIM for the Isle of Man. While a phone number is not provided, users can still make calls and send messages through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, the availability of these services can vary, so travelers should verify that the apps they rely on work in the Isle of Man before buying a plan.
