Avoid.
I have replaced 3 of them with Euronasat. A few comments from customers who had Quantis:

At present I am using http://www.speedtest.net/ and getting speeds of
200kps so it looks like you were right about the Quantis internet :-(


Quantis is the lemon you suggested it was!

I have just been told by Quantis they will charge 900 euros if I cancel the service and although I was told they guarantee 80% speed and 80% up time by Fortec, which quantis is saying is rubbish as they have no guarantees and the service although at 1mb in afternoon and evening speeds are normal to be around 300k!

If you come across anyone else thinking of using quantis let them know of the hidden catch of crap speed when you actually want to use it! Or even point them in my direction and I will warn them.

I'm having a hard time With quantis, its very unreliable solution, they mostly only offer 0.1- 0.3 Mb download

And upload is just not working.

Since I'm using this conection for my work I'm actually f...Ed..
