How this map is built
87% 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.

Frequently asked questions about A1 coverage
Does A1 have good coverage in Croatia?
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 A1 signal there.
Does A1 offer 5G in Croatia?
Yes. A1 runs 5G from 1,601 of its sites. Switch the map to 5G to see the covered areas.
Is the A1 map up to date?
The map is built from antenna data dated October 2026, and the A1 network facts were last verified on August 14, 2026. Sogudo does not resell A1 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 A1?
No. Sogudo is independent and computes coverage from public antenna data.
