How this map is built
Coverage map generated on October 15, 2026.
Antenna sites, heights, azimuths and frequency bands come from the French spectrum agency (ANFR) public register, updated monthly.
100% of the sites have known antenna azimuths: their coverage is drawn as sectors, the others as circles.
100% of the sites have a published antenna height; the model assumes 35 m elsewhere.
Terrain comes from IGN's BD ALTI® 25 m digital terrain model (sea and foreign areas filled with GEDTM30). For every antenna we compute which ground cells are in line of sight: a hill or a ridge between you and the antenna removes the coverage behind it, instead of drawing a full circle.
The GHS-SMOD settlement grid of the European Commission's Joint Research Centre classifies every square kilometre as dense urban, urban or rural. The propagation model uses that class around each antenna: the same transmitter reaches much farther in open country than between buildings.

Frequently asked questions about TELCO OI coverage
Does TELCO OI have good coverage in Mayotte?
Coverage changes from one street to the next, so the answer depends on where you are. Search your own address on the map above to see the TELCO OI signal there.
Does TELCO OI offer 5G in Mayotte?
Yes. TELCO OI runs 5G from 32 of its sites. Switch the map to 5G to see the covered areas.
Is the TELCO OI map up to date?
The map is built from antenna data dated October 2026, and the TELCO OI network facts were last verified on October 2, 2026. Sogudo does not resell TELCO OI data. Coverage accounts for each antenna's sectors, the terrain between you and the antenna, and the density of the built environment around it.
Is Sogudo affiliated with TELCO OI?
No. Sogudo is independent and computes coverage from public antenna data.
