Hello Monika, instead of answering your question, i advise you to search "internet" on the link below:

You will get all topics about the discussions of all ISP in Geneva.

Based on my personal experience I would not recommend them. Box takes 2-4 weeks to arrive, based on the demand, they will not commit on a date. You need to setup everything yourself. Their customer service is a nightmare, gianormous waiting times and lots of mistakes in 4 years. They continued to send me invoices after I canceled the subscription and are still chasing me to pay them almost one year after. Service is ok, but I never reached their advertised speed.

Look into Cablecom if it's available at your address, they have a bunch of offers right now including free wifi router. With them I always get slightly more than the advertised speed at any time of day.

In my limited experience of dealing with them I once signed up for a trial 3 month contract with them in which they offered free national phone calls and set tariffs for international calls. At the end of the 3 months I declined a permanent contract and they charged me CHF 100 to void the contract even though it was meant to be a free trial and there had been absolutely no mention of this fee at any point in signing the documentation, verbally nor in writing. I then found out that they are known for scamming customers and that they are involved in plenty of litigation. So personally I am biased against them and would advise you to make sure you know exactly what you are getting into first.

I had for a bit more than 1 year the usb/takeaway internet, and reception at my apt was just shit (mind, i live in paquis, not in the middle of avully or chancy). I never EVER got a decent signal. When i finally decided to end the contract, surprise, it was automatically renewed for 1 more year cause not cancelled before. Well, my own mistake here, as i did not read properly the contract, though now i just pay 10 bucks per month for the same (shitttyyy) internet. 

OMG, why people still use sunrise or orange.

I used Orange for two years and totally regretted there connection, service was useless. and then one year with Sunrise was only a step up /better. Was like quality from shyt to mud.

if you want good quailty and reliable internet connection, use Cablecom or Swisscom. they give you plenty of help, support and extra. Yeah you pay but you get what you pay for. and is the time lost worst worth it.

Thanks everyone! This was very helpful, and I'll rather go for Cablecom now
