That’s odd. This is the first time that I hear about this problem.

CFUN=1 means switchting on the radio module.

Maybe a capacity or power issue on the device?

Hey Sergey,

We do not have IMSI - IMEI lock configured. All our simcards should be able to work in mutiple devices. I double checked your sim-card configuration as well.

We do have some users who connected the nrf9160 via UDP…

@Eric-Barten (but he’s offline this week) and @Stefan-de-Lange

Thanks for the insight!

I’ll send you a new sim-card then.

Thanks! Just checked your sim-card settings and, everything looks fine from here.

Can you try it like this:

AT+COPS=1,2,"20416",9

I have to admit, I have no clue what the ‘9’ does. However, this is how @Roalnd-Baldin wrote it here in our doclib.

Hmm maybe! Can you send me the ICCID or IMSI via DM here?

Usually this really means that there 's still something wrong with reading the sim.

Can you please try what happens after removing and replacing the simcard in the card-holder?

I think that you did everything right. Something has changed at All Things Talk’s end. We received more complaints about integrations with ATT.

@Eric-Barten already contacted them, but I will give it another try next week.

@Sergey-Vladimirov thx for your enthusiasm!

For now only Quectel and Telit are “nuSIM - ready”. But soon more module vendors will be ready as well.

PS. you also sent an e-mail with another question and we’re trying to get back to you but it looks like your inbox is not accepting new messages

Spain confirmed!

If you’re one of the lucky ones who received a nuSIM dev-kit from my colleagues Mona Parsa and Stefan Kaliner, you’re at the right place to find out how to get this super cool dev-kit online without a plastic simcard!

STEP 1: GET YOUR STARTERKIT PROJECT
Before using the dev-kit, you’ll need a starterkit project environment.

• Sign-up for it by using this link.
• When you’re asked about where to send the simcard select the checkbox of I already have simcards

STEP 2: GET YOUR DEV-KIT ONLINE

• Go to your project
• Register the IMEI of your device
• Attach to the network by using cdp.iot.t-mobile.nl as APN and 172.27.131.100 as gateway for a ping test or to send your uplink messages
• Your uplink payload should appear in the ‘device management’ tab of your project page
• If you do not know how to attach to the network, check out the AT-commands below

AT-COMMANDS TO ATTACH TO THE NETWORK

Switch-off the radio module

AT+CFUN=0

Configure basic connectivity parameters

AT+NCONFIG="AUTOCONNECT","TRUE"
AT+NCONFIG="CR_0354_0338_SCRAMBLING","TRUE"
AT+NCONFIG="CR_0859_SI_AVOID","TRUE"

Set the APN

AT+CGDCONT=0,"IP","cdp.iot.t-mobile.nl"

Set the band

AT+NBAND=8,20

Select the Operator

AT+COPS=1,2,"26201"

Telekom Germany = 26201
T-Mobile Netherlands = 20416
T-Mobile Poland = 26002
Or use the PLMN ID of any other operator within our NB-IoT roaming footprint

Switch-on the radio module

AT+CFUN=1

After not more than 30 seconds, your device should be attached to the network.
Now you can proceed with registering the IMEI number of the module in your starterkit-project and send your Hello World uplink message!

To follow the AT-commands below, it is important that you register the IMEI as UDP.

AT-COMMANDS TO SEND YOUR UPLINK

Open local UDP-socket

AT+NSOCR="DGRAM",17,7000,1

Send your uplink-message (2x)

AT+NSOST=0,"172.27.131.100",15683,11,"48656c6c6f20576f726c64"

Make sure to send it twice, in order to see your message in your starterkit project.

That’s it!

Feel free to reach out in case of any questions!
