Ubigi does not offer an eSIM for Guinea‑Bissau that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider in that country.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, because some destinations may block or restrict access to certain apps or services, it is advisable to confirm that the applications relied upon work in Guinea‑Bissau before purchasing a plan.
