PH8 network selection with roamed network | Telit Cinterion IoT Developer Community

I have many devices with PH8 FW 03.320.
All are suffering from network selection issue with roamed networks.Everything is okay when I'm using regular SIM cards from homeland operators.
But when I'm using SIM cards from roamers operators, the PH8 is always changing from one roamed network to another one (about every minute), doing +CREG 5 (PLMN A), +CREG 2, +CREG 5 (PLMN B), +CREG 2, +CREG 5 (PLMN C), +CREG 2, +CREG 5 (PLMN A) ... and so on.
It is not possible to attach a roamed network and stay on it.
Added Note: Requesting AT+CREG? makes the modem attach correctly for about 10 to 20 minutes, but switches networks again after that.
