Hello,
The logs indicate that either the SIM is not inserted, or the modem is hung up and it does not appear to be connected to any operator.
I also see that Network -> Mobile -> Operator networks has manual operator setting. Could you change it to Auto?
In addition, could you try updating your device's firmware to 7.04.1, which can be downloaded here. If possible, update with Keep settings option set to off, but keep in mind that this will clear your configuration.
Best regards,
