How to get your nuSIM dev-kit online?


  • Deutsche Telekom IoT

    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! 😃



  • @afzal_m very exciting topic:) I haven’t got nusim devkit, but I’m very interested in the topic. Would it work on some specific modules, if yes on which ones? And when would we expect availability?
    Thanks!

    @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



  • Hi Afzal,

    Following your guide to get my T-Mobile nuSIM kit online, but run into some issues with the AT+CGDCONT and AT+COPS commands. Also I noticed standard commands like ATE1 and ATI don’t seems to work, but that might be a ‘feature’ of the custom nuSIM firmware(?).

    Thanks in advance for your feedback!

    Here’s a log of my terminal:
