Declared locations include Le Bettex D'en Haut, Le Bionnay, Le Fayet, Panloup, 995 rue du Mont Joly and Le Bois des Nants.

ANFR has approved 3 new sites that are not live yet, plus additions on 2 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at Le Chosal, Bouygues Telecom (3G and 4G) at Le Plane Sud and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Sous le Bois. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2017 was the busiest year, with 33 new systems, most of them 4G. Free Mobile switched on the first 5G here in January 2021; SFR followed in September 2021, Bouygues Telecom followed in October 2021. The oldest transmitter still listed here goes back to 1996.

The highest support stands 36 m at Le Bois des Nants (pylon). The median height of measured supports is 24 m.

Of the 10 masts in the commune, only one mast carries all four networks, and Orange is the only carrier on 3 masts.

3.5 GHz 5G is declared by Bouygues Telecom on 3 of its 5 masts, Orange on 3 of its 6 masts, SFR on 3 of its 5 masts and Free Mobile on 1 of its 3 masts.

Supports leave a gap of about 2.6 km to the south-west of the centre.

Passy lies 3.9 km to the north-west and has a camouflaged "tree" pylon among its supports.

By mast count, Saint-Gervais-les-Bains is 9th of the 33 Haute-Savoie towns that have five or more. With 10 masts for 5,755 residents, or 17 per 10,000, it has more masts per inhabitant than the median for those towns (10).

Most of the town's 10 masts are pylons (5).
