I have a site with a RUT240 on a roaming data-only SIM. It has been working for several months but has recently become unreliable. I have just made a site visit and have found that the RUT240 is connecting to the mobile network fine, has a signal level of -53dBm which is more than adequate for a reliable 4G connection, but is stating that the data connection is disconnected. I have talked to the SIM provider and they can't see a problem at their end. They suggested that I put the SIM into another mobile device. Putting it into my smart phone I could get the data connection to work fairly easily. As soon as I put it back into the RUT240 it doesn't connect.

I have checked the event logs and can see that it is not getting a WAN IP address from the mobile network provider, yet it does when I use my smart phone. I can see that it does get an IP address sometimes but only one time out of about 40 times at best. I am struggling to understand why it isn't getting a WAN IP address. I have checked the APN configuration with the SIM supplier and it is setup correctly. I have also looked at Teltonika guides, FAQs and other community forum posts, and can see nothing obvious to suggest why there is this problem.

I have run the Troubleshooting file creation process which can be provided if required.

If you could provide the troubleshoot file and send it to me via private message that would be really helpful.
