GigSky does not offer an eSIM plan for Gambia that includes a phone number or SMS capability. Only data‑only eSIM plans are available, so travelers will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. Some destinations may block or restrict access to these services, so users should verify that the apps they depend on are accessible in Gambia before purchasing a plan.
