Enter your address and you see which line is recorded there, what speed is possible and which providers have their own network. The basis is the official data of the Federal Office of Communications, not an estimate.
Only providers with their own line on site are listed. Those missing often still sell there, most of them additionally rent wholesale access.

Enter your address above. The lookup reads the OFCOM broadband map and shows three things: which connection types are recorded, what speed is possible, and which providers own a line there.
It is the same official source the providers rely on when they build their own availability checkers. The difference is that here every provider appears, not just one.
Not that they do not sell there. The map lists only providers with their own line.
Most of them additionally rent wholesale access and sell far beyond their own network. GGA Maur appears in only a few places in this layer and still sells fibre across Switzerland. Concluding from absence that a connection is unavailable is wrong in most cases.
By the upload. Fibre carries data equally fast in both directions, DSL does not.
An offer with 1 Gbit/s download and 100 Mbit/s upload runs over copper, even if the product name says Fiber. The second clue is the modem: fibre needs an optical socket on the wall rather than a telephone socket.
The socket in the flat where the fibre ends. Often called an OTO, for Optical Telecommunication Outlet.
A thin optical cable runs from there to the modem. The socket is installed during the rollout and belongs to the building, not to the provider. When you switch provider it stays, at most the modem is exchanged.
Yes. Ten gigabits are available over fibre only.
Cable in Switzerland currently reaches up to 2.5 Gbit/s, copper considerably less. According to the OFCOM telecommunications statistics, 73.7 per cent of fibre connections already run at the 10 Gbit tier, and the number of optical lines grew by 11.3 per cent in 2024 while copper lines fell by 5.8 per cent.
