3.5 GHz 5G is declared by Bouygues Telecom on 2 of its 3 masts, SFR on 2 of its 3 masts and Orange on 1 of its 3 masts. Free Mobile only has 5G on 700 MHz — longer reach, lower speed. 67% of the town's masts carry 5G, fewer than across Seine-Maritime towns with five or more masts (88%).

2023 was the busiest year, with 16 new systems, most of them 5G. Free Mobile switched on the first 5G here in December 2020; Orange followed in February 2023, SFR followed in August 2023. The oldest transmitter still listed here goes back to 1995.

Approved additions not yet in service are pending on 4 existing masts, for example Bouygues Telecom (2G 900 MHz) at Le Cabaret, Free Mobile (5G 3.5 GHz) at Mont Blanc and Orange (5G, including 5G at 3.5 GHz) at Plaine de Flocques. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Of the 6 masts in the commune, Orange is the only carrier on 3 masts.

By mast count, Criel-sur-Mer is 26th of the 30 Seine-Maritime towns that have five or more. With 6 masts for 2,527 residents, or 24 per 10,000, it has more masts per inhabitant than the median for those towns (8).

Supports leave a gap of about 1.8 km to the north-east of the centre.

Nearby, Le Treport (6.6 km to the north-east) has 6 masts declared.
