I have ordered several easyconnect SIM cards from T-Mobile and want connect a MKR NB 1500 via LTE-M to an azure IOT-HUB. I have this now working for two devices wich I have configured a few months ago. But now I have a problem with the registration for the rest of the devices. The response that I got from the modem is stated below. It looks if the cards are not registered in the portal but I don’t no how to fix this. Ik hope the @Afzal-Afzal or @Eric-Barten can help me to solve this problem.
