@MarcoPeli Thank you, this was the problem.

Hello,
I’m trying to send a downlink message to our device.

I’m calling the following endpoint:
https://api.scs.iot.telekom.com/m2m/endpoints/IMEI:<our_device_serial_number>/downlinkMsg/0/data

but I receive an HTTP “403 Forbidden” status response, with body:
{
“msg”: “Unauthorized”,
“code”: 1001
}

I added an “Authorization” header with a Basic format value, which seems correct because a call to the end point “https://api.scs.iot.telekom.com/rest/device” works.

The application “Callback URL” is configured.

Could you please help me finding what’s missing or wrong ?

Hello,
Do you confirm that NB-IOT roaming in France is not yet available, or it is now available ? I am trying to connect without success.

Hello, when I enter the form with the number of SIM Card, Address, etc… there is an error when I click on the Submit button. “There has been an error please try again”. (It looks like the error message is “401 unauthorized”

Hello, it is possible in NB-IoT with your SIM for the device to send UDP data to a IP on Internet, and also in Downlink it is possible to have a fixed IP so that an Internet Server can send data to the device (in UDP) ?
