Guinea-Bissau: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →Guinea-Bissau has two major mobile network operators: MTN and Orange. Both networks commercially offer 3G and 4G/LTE services. Roaming users on these networks are likely to connect via LTE Band 3 (1800 MHz) and Band 8 (900 MHz), which appear to be the key frequency bands deployed in the country.
Regarding eSIM availability, local carrier support for eSIM technology in Guinea-Bissau is currently being verified and cannot be confirmed at this time. Given the low confidence level in the available information, travelers and potential users should contact the operators directly for current details on eSIM issuance and other service specifics.

Compiled from public-record telecom facts (the MNO roster, commercially-launched 3G/4G/5G generations, deployed travel-relevant bands and local-eSIM support) and verified June 2026; see the source we compile this country from. Local-eSIM availability checked July 2026 against the major carriers' own pages. This country's connectivity row is low-confidence (small / island / single-operator / fast-changing market): some details could not be confirmed from official sources in our July 2026 check, so treat the carrier, band and 5G specifics as a starting point.
