AdventureSIMs eSIM Data Plans for Guinea-Bissau

AdventureSIMs does not offer an unlimited data eSIM plan for Guinea‑Bissau. Their catalogue for the country consists of fixed‑data plans. For instance, a 20GB plan is available for 30 days at a price of $86.86 USD, while a 10GB plan for the same validity costs $49.12 USD and a 5GB plan is priced at $26.34 USD.

Because no unlimited option exists, travelers who anticipate very high data usage may find the fixed plans less ideal. For most users, however, a fixed‑data plan can be more cost‑effective unless the usage is exceptionally heavy.

AdventureSIMs does not provide an eSIM for Guinea‑Bissau that includes a local phone number or SMS functionality; only data‑only plans are available. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging purposes.

AdventureSIMs provides five multi‑country plans that include Guinea‑Bissau, but no single‑country plans are available. Each plan offers a fixed data allotment ranging from 1 GB to 20 GB, with validity periods between 7 and 30 days. Prices span from approximately $9.96 to $86.86 USD. All of the plans allow tethering.
