My Rutx 14 does not want to roam with my work KPN sim cards. working on site at the german border, it keeps wanting to connect to the weak home signal, instead of a strong german signal.
I checked with the provider and they say there is no limitation on the simcard, I should seek help from Teltonika.
Some things I've tried so far:
1. Tried to use a different sim, with my tele 2 sim it roams without any problem, depending on provider.
2. I put the sim from the modem in my mobile phone, In the phone all sims are able to roam without any problems.
3. I tried manually switching to a foreign provider but it does not register.
4. Deny roaming is switched off, Volte auto, service mode auto and band selection auto.
I read somewhere that you should switch autoAPN off, however I can not find any apn settings.
