MTX Connect does not provide Gambia eSIM plans that include a phone number or SMS capability. The available eSIMs from this provider for Gambia are data‑only, so travelers will need to use VoIP services—such as WhatsApp, Telegram, or iMessage—over the data connection for voice and messaging. However, some destinations may block or restrict certain VoIP apps, so travelers should verify that the apps they rely on are accessible in Gambia before purchasing a plan.
