With other SIMs it will work fine. <br> <br> The modem is a SIM7600G.<br> <br> Here is a log with --debug enabled <a href="https://sprunge.us/UR3gvX">https://sprunge.us/UR3gvX</a><br> <br> Sometimes the problematic SIM will work and connect the device to the internet, but I have not found a way to reliably recreate this scenario.<br> <br> Cheers,<br> <br> Daniel Edwards<br> Q Yachts Oy<br> <br> Technical Engineer<br> <br> <br> </div> </div> </body> </html>
