Why travellers use an eSIM in Guinea-Bissau
A Guinea-Bissau travel eSIM lets you add a local/partner data line without swapping plastic SIMs. Keep your home number for calls and messages while mobile data runs on the travel profile.
Order from Layer 9, receive a QR instantly, and install on Wi‑Fi before you leave. That way you are not hunting airport kiosks after a long flight.
- Instant QR delivery after purchase
- Keep your primary SIM installed
- Fixed plan pricing before you travel
- UK-based Layer 9 support

FAQ
Do you offer eSIM plans for Guinea-Bissau?
Browse the live catalogue on the plans page and filter for Guinea-Bissau. Destination pages stay published so travellers can find setup guidance even as packages change.
My Guinea-Bissau eSIM is installed but I have no data — why?
Almost always Data Roaming is still OFF on the travel eSIM line. Turn it ON for that line only, and make sure mobile data is assigned to the eSIM.
Will this charge my home carrier?
Not if home-SIM Data Roaming stays OFF and mobile data uses the travel eSIM.
