Two retailer brands on the Swisscom network: Migros Mobile with fixed permanent prices and Cumulus points, Coop Mobile with lifetime promo prices and payment in Superpunkte. Same network, different pricing model.
Migros Mobile convinces with fixed, transparent permanent prices and no small print, which makes it the simpler deal. Coop Mobile can work out cheaper if you catch a running promotion, because the promo price then stays valid long term, but its regular base prices are high and there is an activation fee. Both use the same Swisscom network, so network quality is identical. For collectors the loyalty programme decides: Cumulus at Migros, Superpunkte at Coop.
