Help with activation NB-IOT on production device
I have a starterkit with NB-IOT sim, and am trying to install this in a device from Digital Matter which is equipped with an U-Blox SARA R410. I’m not allowed to send AT commands, but can configure the device via a back end server.
It looks like the sim is not working and I’m not able to connect the device.
How can I check if the sim is OK, since it’s not visible as sim in my portal?
Your sim is active with the correct profile. Can you check if the solution in this topic https://forum.iot.t-mobile.nl/topic/317/geen-at-response-met-sim-kaart/5 will solve your problem?
