Cell towers in Issoire (Puy-de-Dôme)

Antennas are listed at Pré des Clos, Avenue du Docteur Bienfait, 233 Chemin de la Chaux, La Safournière, 11 rue Muratore and Rue du 19 Mars.

Over the past 12 months ANFR recorded 27 new systems here. ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 106 Rue de Bizaleix and SFR (4G and 5G, including 5G at 3.5 GHz) at 106 Rue de Bizaleix. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (6 of 10), so heights stay modest; the tallest support is 46 m at Pré des Clos.

Systems from 1998 are still on the register. Free Mobile opened 5G here in December 2020; SFR followed in August 2021, Bouygues Telecom followed in September 2021. 2018 was the busiest year, with 22 new systems, most of them 4G.

6 supports carry only Orange.

Among the 25 Puy-de-Dôme towns with at least five masts, Issoire ranks 10th by mast count. With 10 masts for 15,115 residents, or 7 per 10,000, it has fewer masts per inhabitant than the median for those towns (14).

On 3.5 GHz, the fastest 5G band: Orange on all 6 masts, Bouygues Telecom on all 4 masts, SFR on all 4 masts and Free Mobile on 1 of its 2 masts. 5G is on 100% of masts here, against 88% across Puy-de-Dôme towns with five or more masts.

22 km to the north, neighbouring Cournon-d'Auvergne has 22 masts, more than here.

Supports split between 6 buildings and 4 pylons.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
