MobiMatter eSIM Data Plans for Guinea-Bissau

MobiMatter does not provide an unlimited‑data eSIM for Guinea‑Bissau. Travelers who need data there can choose from MobiMatter’s fixed‑data plans. For example, the Best World 25GB plan gives 25 GB of data for 90 days at $69.99 USD, while the Best World 10GB plan offers 10 GB for 30 days at $39.99 USD. Fixed‑data plans can be more cost‑effective for most users, unless a passenger is an extremely heavy data consumer.

MobiMatter does not provide Guinea‑Bissau eSIM plans that include a local phone number or SMS capability. Only data‑only eSIM offers are available from this provider for the country. Travelers who need voice or text may use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Guinea‑Bissau before purchasing.

MobiMatter offers four multi‑country data plans that include Guinea‑Bissau. The plans provide between 1 GB and 25 GB of data and are priced from $8.99 to $64.99, with validity periods ranging from 30 to 90 days. All plans allow tethering, giving travelers flexibility to share the connection with other devices.
