Two low-cost providers on the Salt network: GoMo, the online arm of Salt with one radically simple unlimited plan, and spusu, known for transparency, fair terms and a free eSIM. Same network, two approaches.
GoMo has the lowest permanent unlimited price in Switzerland, but its base plan comes without roaming and, per our data, without 5G. For travel, GoMo offers a separate Europe plan. spusu in turn includes EU roaming data in every plan, a free eSIM, 5G on selected tariffs and very good customer satisfaction (Peer Score above). If you only use data in Switzerland and want to save as much as possible, take GoMo. If you want roaming included and top service, spusu is the better fit. Both are on the Salt network and cancellable monthly.
