Hi VykintasKuzma
> RUT240 does select operators based on connection quality at the moment.
I don't think that is the case. I did a number a power cycles, and without any changes to settings or hardware, the RUT240 went through various operator/cells:
- Vodafone -> Three -> EE (Cell A) -> O2 -> EE (Cell B) -> Vodafone -> EE (Cell C)-> ...
The different carriers (and to a lesser extent the different EE cells) have quite different signal strength at the location of testing! Here are the outputs of gsmctl --serving after each power cycle & some settling time:

As you can see from the last 5 columns (<rsrp>,<rsrq>,<rssi>,<sinr>,- according to this forum posting ) the signal strength varies quite a bit.
So how is the RUT picking the cell?
