Simsima does not provide an unlimited‑data eSIM plan for travelers going to Guinea‑Bissau. The provider offers fixed‑data eSIMs instead. Popular options include a 20 GB plan valid for 30 days and a 10 GB plan also valid for 30 days, both supporting 5G connectivity. These fixed‑data plans can be a more cost‑effective choice unless a user needs very high sustained data usage.
Simsima does not provide an eSIM that includes a local phone number or SMS support for Guinea‑Bissau. The only plans available for this destination are data‑only eSIMs, so travelers will not receive voice or SMS capabilities tied to a local number.
Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage to make calls and send messages over the data connection, since those services work through the internet rather than the mobile network.
The provider offers a total of 12 multi‑country plans for Guinea‑Bissau, with prices ranging from about $5.63 to $80 and data caps between 1 GB and 20 GB, while validity periods vary from 5 to 180 days.
