It's not the same network. There are three providers in Switzerland. From my own experience the most expensive one (Swisscom, by whom this article is) has much better coverage in the mountaineous areas compared to the other two.

Might be a case of decoy effect in action. Swisscom (the expensive option) gets more customers by introducing a cheaper option with worse support.

Well, thanks for telling me that!
I went swisscom-> mbudget on my fixed line but it seems wingo offers the full 1gbs up/dow for less than I pay now for mbudget mini. Guess I'll change soon
