Moto G 2014 dual SIM weak signal

I own a XT1068 Moto G 2014. I use 2 SIMs with it, both in the 900/1800 MHz band in Europe (GSM).

Since day 1 I have had trouble with this phone. In fact, I even returned it to the store (Amazon) and got a replacement. Same problems: first SIM will have weak signal, or completely lose it. A phone reboot is required to return to normal.

If I remove the second SIM, then first SIM works fine: no more signal loss or weak signal.

Is anyone experiencing this problem too?

Both devices have always been running Lollipop, so I cannot say what happens with Kit Kat.
