Question about Digitec iot Data Flat

Both: In the notebook or pad, as well as in the router, you can use it for internet...

Thank you very much for your answers. The 10Mbit would be more than what the DSL line gives at the moment. To be exact, it's double the download speed and 5 times the upload speed. Current provider: 5Mbit/1Mbit around 40 per month.
So for 110 per year with the speed offered, this alternative is an absolute upgrade for me. The idea is that it will really only be used as a fallback alternative. Thank you very much.

10 Mbit/s is absolutely unsuitable for operating a router, especially not with several clients. This modest speed is certainly sufficient for Internet of Things applications, but for more than a little data exchange back and forth, that is so modest, I would never do that to myself. In April 2023, a major provider will offer a SIM solution for 20 francs per month for 2 years, which is also suitable for routers, and that for 5G and up to 2 Gbit/s (2000 Mbit/s). This will cost more per year, but you will have a much better connection to the internet.
