Hi, I just received my nRF9160DK and I have been following the guide to getting it online. I'm at the stage where I am trying to activate my SIM card that came with the kit on the nrfCloud website, but I keep getting the following error after giving my user info on the registration form: "There was an error submitting your user information. This SIM cannot be activated". I looked at other questions on this site, but other users were in countries without LTE-M, which is not the case for me. Could someone help me figure this out so I can get started with this kit?
