I think each of these questions have been discussed to death on this forum and you could just read the last couple of threads in this subsection of the forum.
- Swisscom prices are a bad joke, both new as well as old.
- Sunrise and Salt both have decent networks these days, but Swisscom still has a (tiny) edge according to rather good annual tests by Connect.
- that online storage sounds like the worst sales argument ever. How much are you currently paying for your online storage? How much of it do you need?
