Two Christmases ago, I went with their mobile tarrif, and am still on it. They only act as the middleman for the initial transaction, then all the billing and customer care is done through Sunrise.
The deal is real good, all inclusive withing Swiss plus EU/US calls and roaming.
I heard their network is quite good in cities, a bit less in the mountains or countryside.
The city has some good and bad areas but it's generally ok. You only have to go a little way out of the city in certain directions though and it is awful.
I think it's pretty good in the major towns and cities so if that's where you'll be using it most it will probably be fine. It's also a couple of years now since I ditched them so they may have improved now.
A belated massive thanks for posting this deal, I've been on the Freedom SuperMax at 55chf/month for 6 months now with no complaints at all. Good LTE coverage down here in Ticino, and no problems roaming on our many foreign trips.
Sunrise just sent another sim card for free so the other half can use it in a dual sim phone for roaming data, we had big problems getting Lyca roaming to work on a recent London trip. Plus Sunrise just a text saying roaming data is going up to 2GB from next month.
Only downside is roaming in Italy it will sometimes not give data unless you manually set it to 3G only in the settings.
