Of the 21 masts in the commune, 4 masts carry all four networks, and Free Mobile is the only carrier on 7 masts.

By mast count, Romans-sur-Isere is 3rd of the 21 Drôme towns that have five or more. With 21 masts for 33,464 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

3.5 GHz 5G is declared by Free Mobile on 8 of its 11 masts, Orange on 5 of its 10 masts, Bouygues Telecom on 4 of its 9 masts and SFR on 4 of its 9 masts. 67% of the town's masts carry 5G, fewer than across Drôme towns with five or more masts (80%).
