Hi,
I’m following the Getting Started guide but have had no success establishing a cellular network connection.
I’m using a prepaid SIM from Super (Telia) in Estonia. The SIM card is activated and works well on an Android phone. However, when I use the same SIM on the Sixfab 5G modem kit, I can’t establish a cellular connection.

As a newbie to cellular networks, I would appreciate some guidance for further debugging.
Thank you!
