GigSky does not offer a Cameroon eSIM that includes a phone number or SMS capability. The provider’s eSIM options for Cameroon are data‑only plans, so travelers can use internet‑based voice and messaging services such as WhatsApp, Telegram or iMessage over the data connection. Some destinations may restrict certain VoIP services, so it is advisable to check whether the apps you rely on are accessible in Cameroon before purchasing an eSIM.
