AdventureSIMs eSIM Data Plans for Guinea-Bissau

AdventureSIMs does not provide an unlimited data eSIM for Guinea‑Bissau.

The available plans are fixed‑data options, for example a 20GB plan with 30 days validity costing $71.97 USD and a 10GB plan for 30 days costing $40.78 USD. Choosing a fixed‑data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer.

AdventureSIMs does not provide an eSIM for Guinea‑Bissau that includes a local phone number or SMS capability. The only plans available for this destination from the provider are data‑only options.

Travelers who need to make voice calls or send messages can rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm that these services work in Guinea‑Bissau before purchasing an eSIM.

AdventureSIMs provides five multi‑country data plans that cover Guinea‑Bissau, all of which are available across a range of pricing from about nine dollars to eighty‑six dollars, with data caps that vary from one gigabyte to twenty gigabytes. The plans run for anywhere between seven and thirty days, and tethering is permitted on many of the plans.
