I use 3BB VDSL as a primary connection for VoIP and I'm in need of a backup connection.
So I'm thinking about using a 4G internet dongle with AIS, DTAC or True.
If you are using such a dongle, could you please provide me with speed test results, including jitter, for a host located in Zurich, Switzerland.
Here is one webpage that does this:

be sure to select another host, and choose one located in Zurich, Switzerland.
thank you
