DT85M failed to communicate via SIM with message: "Modem will retry [SIM problem]".
SIM was removed and reinserted and slide catch engaged and checked that was fully engaged.

SIM had been working for a number of years without problem then the issue started a couple of weeks ago when emails containing data ceased.

Hi houghje,

We apologize for the late response due to an issue in our backend server.
It is possible the infrastructure to support the service may get reduced especially when you use a 3G network. Please check modem diagnostic P56=16 to get a detailed response from the network.

We recommend you start the migration to 4G using an external 4G router.

Best regards,
