Hi,
I have a RUT240 with FW ver.: RUT2XX_R_00.01.03.5. Using a prepaid SIM, operator Tre (Three) in Sweden, works fine. But when using a contract SIM from the same operator AND with additional service "static IP" it fails. After a lot of "trial end error" I got it to work: added "option proto 'dhcp'" in /etc/config/network section "interface 'wan'" and changing "option proto 'qmi2'" to "option proto 'wwan'" in /etc/config/network section "interface 'wan'" and /etc/config/simcard section "sim1 'sim1'". (I also removed "option profile '238'" from /etc/config/simcard section "sim1 'sim1'").
I actually don't have enough knowledge how to do this type of configuring, please tell me if it's correct or how it should be!
I propose you add testing of contract SIM cards from this operator (Tre, in Sweden) both with additional service "static IP" and without that service. Also, add it to your mobile setup wizard (APN "bredband.tre.se" for no static IP and APN "static.tre.se" for static IP).
