These are the two cheapest unlimited plans in Switzerland and only a few centimes separate them. Digital Republic Flat Swiss on the Sunrise network against GoMo on the Salt network. The price is almost the same, the package is not.
GoMo is nominally a few centimes cheaper, but has no roaming and, per the data, no 5G. Digital Republic Flat Swiss offers 2 GB of EU/USA/UK roaming and 5G for practically the same price, on the Sunrise network. Anyone who is even occasionally abroad or wants 5G is clearly better served by Digital Republic. Anyone who never travels and prefers the Salt network saves a minimal amount with GoMo.
