Who is a good provider for mobile internet in Switzerland?

It is not correct that you cannot buy a SIM Card if you are not Swiss. You can, and many do every day.

The best coverage in Switzerland is offered by Swisscom (especially in more remote areas). Sunrise has good coverage as well.

With Sunrise you can get a PAYG SIM for free, and then you pay CHF 1.20 per day for internet.

Note that a bandwidth of 10 Gbit/s is something that is only achievable with fiber optics at the moment. You are probably confusing bandwidth with data volume.

Depending on your german provider, you can get a roaming package for Switzerland.

As far as I know, Telekom includes Switzerland in der general roaming package. Other providers offer additional roaming packages for all parts of the world. They are often marketed as travel packages and are valid for a week or a month. Getting such a package for a few weeks is probably easier and cheaper than getting a Swiss SIM card.

This is what I use, living in Germany close to the Swiss boarder and traveling there frequently for work.

Whoever told you you can't buy a SIM card as a foreigner was lying to you.

Swisscom has unequivocally the best coverage, so if you're going to be staying somewhere away from major cities/ places, I'd go with Swisscom. Sunrise is second best in terms of coverage, and they're a little more expensive but offer better benefits. And lastly you have Salt, they have the worst coverage, are as expensive as Swisscom base and internet will cost you a pretty penny.

Here's a short comparison:

• Swisscom (prepaid info here)

  • 2 CHF per day to surf the internet with up 10 Mbit/s download and 2 Mbit/s upload up to 10 GB where the speeds drop
  • 0.29 CHF per minute for calls
  • 0.15 CHF per SMS within Switzerland and abroad

• Sunrise (prepaid info here)

  • 2.50 CHF per day to surf the internet with up to 300 Mbit/s download and 150 Mbit/s upload
  • Unlimited calls and SMS to all Swiss landline and mobile networks, but 0.25 CHF per SMS going abroad
  • 20 CHF activation fee for the SIM card, but it includes a free credit of 25 CHF on your prepaid plan

There is also the option of going with something like Lycamobile, Migros M-Budget prepaid or Coop prepaid, but I personally cannot recommend any of them as I haven't any experience with their service

For my Swiss sim I use lyca mobile. Its easy to get hold of and buy packs that give you a certain amount gb for the month.

I basically never phone people so it fit me perfectly as all I wanted was internet. I believe you can order it before even going to Switzerland. It can also be bought in papershops in Switzerland.

IIRC there was a little bit of work at first having to fill in a form and get someone in a shop to register it for me, but overall a much better option than paying 40 francs a month for swiss com or the others.

Stear clear of proper mobile phone shops and look to the little immigrant focussed papershops and you'll be sorted. A foreign ID is fine.

Also worth looking into are lebara mobile, who do basically the same thing. There may be one or two others too.

One thing to keep in mind: Only Salt, Sunrise and Swisscom have an actual mobile network, all other providers use one of those.

A good place to look for mobile phone products is Comparis, it allows to find good offerings based on your call/data profile.

I use Lebara, though there are several other providers which offer a prepaid service. You can buy a SIM at any post office, you will need to present some form of identification (Ausweis). The basic SIM costs under CHF 20. You can get a monthly data plan for CHF 15 or so. The procedure is painless. Some post offices even carry inexpensive (CHF 20-50) phones locked to one or another prepaid service. I have a lot of cheap phones I use to connect to free WLAN services (SBB, Migros, Coop, etc.)

You do not need to be Swiss, nor a resident. I used Lebara before I was a Swiss citizen.

To top off, I normally do it at the ticket machine at an SBB railway station. Here you simply enter the telephone number +76 .... and the amount you wish to add (say CHF 20). It might not work with a credit card, it will not work with a REKA card.

Lastly, the Lebara here is incompatible with Lebara UK or Lebara DK.
