BC68 and BC68GV connectivity in Sweden

Hi,

Our devices using BC68 and BC68GV are working fine across multiple countries in Europe.

When our device is in Sweden on Tele2 or Telenor they do not connect to the network.
This happens with both BC68 and BC68GV.
As the device is remote and offline there is no functionality to diagnose the issue at the moment.

Does anyone have similar experience in Sweden and share any insights in solving this? This would be appreciated. Thanks!
