Mobile data is not working (shows.‘limited connectivity’. Imho it can be related to the mnc setting for the service provider, since mobile vikings changed already 3 times the carrier network they use. And as I look into /system/etc/apns-conf.xml the mnc seems to be from the previous carrier network.
However correcting this didn’t solve the connection issue.
Apn is correctly configered in the interface, but mnc values cannot be changed there.
Were can I correct the apn settings on the device and putting the right mnc.
