yaySIM does not currently provide Gambia eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for travel to Gambia from this provider.
With a data‑only plan, travelers can still make voice calls and send messages using popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so users should verify that the applications they rely on are accessible in Gambia before purchasing.
