How this map is built
Antenna sites, heights, azimuths and frequency bands come from the French spectrum agency (ANFR) public register, updated monthly.
99% of the sites have known antenna azimuths: their coverage is drawn as sectors, the others as circles.
99% of the sites have a published antenna height; the model assumes 35 m elsewhere.

Frequently asked questions about SFR coverage
Does SFR have good coverage in France?
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 SFR signal there.
Does SFR offer 5G in France?
Yes. SFR runs 5G from 17,202 of its sites. Switch the map to 5G to see the covered areas.
Is the SFR map up to date?
The map is built from antenna data dated October 2026, and the SFR network facts were last verified on August 17, 2026. Sogudo does not resell SFR 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 SFR?
No. Sogudo is independent and computes coverage from public antenna data.
