Supera link does not provide a Cameroon eSIM that includes a local phone number or SMS capability. The only eSIM offerings from Supera link for Cameroon are data‑only plans, so there is no telephone dialing (dialing code, inbound or outbound voice) or inbound/outbound SMS support.
If you need to communicate while traveling in Cameroon, you can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. These applications allow voice and text communication without a local phone number or SMS.
