MobiMatter does not provide Guinea eSIM plans that include a local phone number or SMS capability. Only data‑only options are available from this provider for travelers visiting Guinea.
While a phone number and SMS service are absent, you can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging. Since some destinations may restrict or block specific apps or VoIP services, travelers should verify that the platforms they rely on are accessible in Guinea before purchasing an eSIM.
