How this map is built
82% of the sites have known antenna azimuths: their coverage is drawn as sectors, the others as circles.
82% of the sites have a published antenna height; the model assumes 35 m elsewhere.

Frequently asked questions about Algar coverage
Does Algar have good coverage in Brazil?
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 Algar signal there.
Does Algar offer 5G in Brazil?
Yes. Algar runs 5G from 198 of its sites. Switch the map to 5G to see the covered areas.
Is the Algar map up to date?
The map is built from antenna data dated October 2026, and the Algar network facts were last verified on August 14, 2026. Sogudo does not resell Algar 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 Algar?
No. Sogudo is independent and computes coverage from public antenna data.
