Hello,
The files attached are corrupted and cannot be viewed.
Could you please tell me which firmware version are you using?
One thing you could do is try set the APN manually on your router.
To do this go to WebUI -> Network -> Interfaces click on MOB1A1S1 interface edit button, disable Auto APN and then either select an APN from the list if there is one available or try to search which APNs are used by the operator.
