Hi!
stable 8.2.1.0, SIM1 is the one used for data.
In SIM settings - SIM 1 menu I can choose the preferred network type (4G/3G/2G), but this option is not present in SIM 2 menu! If I manually choose a 2G operator (in my case Vodafone) for SIM2, in a minute or two it goes back to Vodafone 3G without asking. Furthermore, if I select 2G as preferred network type for SIM1, SIM2 still connects on 3G.
On stable 8.1.9, if I manually selected a 2G operator for Sim2, it stayed on 2G until reboot... that's strange!

Is there any way to keep Sim2 "locked" on a 2G operator, in order to drain less battery? I seldom use it for receiving calls, and never for data!

Thanks in advance!
