Two online providers on the Sunrise network: Galaxus Mobile from the Galaxus ecosystem with three lean tiers, and Digital Republic, a transparent discounter with fixed permanent prices and a free eSIM. Same network, different packages.
Digital Republic offers the unlimited Switzerland plan for less than Galaxus and adds roaming data from the base plan, a free eSIM and a clearly higher Peer Score. Galaxus Mobile is interesting if a small data allowance is enough for you, or if you want to manage the plan inside your Galaxus account. For heavy roaming, Galaxus has a dedicated international plan. Both run on the Sunrise network and are cancellable monthly, but the gap in customer satisfaction is large, see the table above.
