11 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 6 existing masts. New: Bouygues Telecom (4G and 5G) at 55 rue de Normandie and SFR (4G and 5G) at 55 rue de Normandie. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Of the 12 masts in the commune, only one mast carries all four networks, and Orange is the only carrier on 6 masts.

By mast count, Saint-Lo is 2nd of the 15 Manche towns that have five or more. With 12 masts for 19,471 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (14).

3.5 GHz 5G is declared by Orange on 6 of its 8 masts, Free Mobile on all 4 masts, Bouygues Telecom on 2 of its 3 masts and SFR on 2 of its 3 masts.
