nRF9160DK not connecting to the cellular network after several failures to connect

Hello,

I have a problem regarding the connection to the cellular network of the nRF9160DK.

When I boot up the device and I have uploaded a code to connect to the network, the device has no problems.

But when I remove the SIM card to try to connect again it only connects if I put the SIM back immediately and it connects on the first try.

If I wait several times to try to connect without a SIM and then I connect it it just says that is is changing cells and stops there and does nothing else.

I have to restart the whole device in order to make it work again. And just the reset button or flashing the code again doesn't work, it has to be disconnected from the power.

As a code for that I am using the nRF9160: AWS IoT sample code.

Thank you for the help!
