Hello everyone,
I have some questions concerning IoT SIM cards used in cars.

Many vehicles in European market are now equipped with IoT SIM cards, and the European Union has a mobile roaming policy known as “Roaming like at home,” According to this policy, SIM cards obtained in one European country would not incur roaming charges when traveling to other countries. We want to figure out whether the “Roaming like at home” policy applies to IoT SIM cards, or it only applies to phone SIM cards.

As far as we know, when the driver uses smart devices in the car, he or she needs not to conduct real-name registration, but when someone in the car uses vehicle WIFI (hotspot), he or she must conduct real-name registration. We want to figure out which regulation in Europe requests this.

Thank you for your time and we greatly appreciate your expertise in this area.

Best Regards,
Grace

Hello @Mariusz2482

you are very welcome. I am glad to hear you got it working to your liking.

Thanks
Felix

Hi @Wolfgang6177 ,
If you have a DT tariff that includes LTE/4G, then you may also access our LTE-M network. Yet for NB-IoT, you need a dedicated Multi-Mode tariff and SIM-card (Global SIM).
Please follow this link for more details.
Kind regards, Ronan

@Mikael-Guenais If you order a free starterkit (incl. 1 SIM) you should be able to do the order process directly in the standard order flow. If you want to buy SIM cards, please reach out to support@iotcreators.com and we will help you out with your order. Sorry for the inconvience.

Hi @uta, thanks for the tip. You’re right, I was using the wrong APN for the type of SIM I have. I have an easy connect SIM, and for that the APN should be just “iot.t-mobile.nl” it turns out (without the CDP bit). Now the UE attaches & registers to the network perfectly fine 😃

And it works ! I could register my SIM card, and after starting my FiPy test program it connected within 30 seconds. Thank you.

@florian-duecker That’s great. Thanks!

@Cher Hi, looking at your screenshot, I think there is a bug in the modem firmware. If you look at the logs on the right you can see:

+CPIN: RE DY

This means the sim card is detected and ready. However, one letter is missing. This is supposed to be +CPIN READY. So I think the serial tool is therefore failing to interpet the correct string.

Can you query the CCID/IMSI? If it returns a number then the sim card is for sure working. You can also try updating the firmware

Hi,

currently it is not possible to query the IMSI of a device via the API.

BUT
the IMSI is delivered along with the lifecycle event when the device registeres it self.
In this case you get forwarded to your configured application url a payload like this.

{ "reports": [ { "serialNumber": "IMEI:123456789012345", "timestamp": 1623278710492, "subscriptionId": "63b07b01-4c14-4bba-8bc4-f3a89b3c94ff", "resourcePath": "uplinkMsg/0/data", "value": "500a060800101a181", "customAttributes": {} } ], "registrations": [ { "deviceType": "device", "serialNumber": "IMEI:123456789012345", "timestamp": 1623278710457, "make": "Generic", "model": "Sensor", "groupName": "TMNL.PROFESSIONAL.CON_0000001204", "imsi": "N/A", "protocol": "HTTP", "tags": "N/A", "subscriptionId": "cc48f3fa-7147-4b6d-9fe7-fe5b108e50dc", "deviceProps": { "device/0/imsi": "IMSI:123456789012346", "device/0/model": "Sensor", "uplinkMsg/0/data": "500a060800101a181", "device/0/manufacturer": "Generic", "connectivity/0/port": "62509", "connectivity/0/mncmcc": "", "location/0/longitude": "", "connectivity/0/cellid": "", "connectivity/0/ip": "10.0.5.183", "location/0/radius": "", "connectivity/0/rat": "", "location/0/latitude": "", "connectivity/0/apn": "" }, "customAttributes": {} } ], "deregistrations": [], "updates": [], "expirations": [], "responses": [] }

You can see the IMEI in the IoT Creators portal because we did some implementation regarding this 🙂

Hope this helps a bit.

Regards, Roland

Yes, the SIM cards that we as IoT Creators send out are always activated when you get them delivered.
And our SIM can connect to the 4G network using our publick APN: m2m.public.nl
You can check our “roaming” page to read about operators and bands that you need for LTE-M at your location, please note that LTE-M is not necessarily available everywhere where you’ve got 4G coverage.
If all this seems to be fine on your end and you still can’t connect please tell us the details where you got stuck. (AT commands and module logs)

Hi @MeneerJacco
please send me your ICCID or IMSI in a private message via the forum chat tool and I’m going to look at your tariff.
Thanks,
Uta

Hi,

I’ve checked and everything seems to be fine on our side. However, of course I cannot see if the SIM card itself got some physical damage. Did you try the other SIM cards that you have?

Florian

For NB-IoT we have an UDP adapter. So with NB-IoT you’ll need to use APN cdp.iot.t-mobile.nl which will allow you to send device data to 172.27.131.100.

To retrieve the device data in your back-end/cloud server/iot platform, you’ll need to create an HTTP integration.

If you use the sim-card for LTE-M or 2G, you’ll need another APN: m2m.public.nl. By doing this, the device will get a public IP address just like any other device on the open internet. This means that you can send device data directly to your own server while using LTE-M or 2G.

Hope this helps!

Good morning @afzal_m, is it possible this Sim requires 3v? This would explain weird behavior when the module provides only 1.8v

@Malte-Neumann Hi Malte, please send the 10 ICCIDs to support@iotcreators.com . I will check them .

Please use as PLMN IDs from page https://docs.iotcreators.com/docs/telekom-iot-networks-in-europe

Regards, Roland

Hi Petr,

if I understood you right I see the following challenges:

find a location with NB IoT coverage. attach your device to the NB-IoT network of T-Mobile Czech. send messages via UDP to Cloud of Things decode the payload of your UDP message and integrate it with Cloud of Things

Please let us get directly in contact, that we can speak about it (roland.baldin@t-systems.com).

Regards, Roland

@afzal_m Hallo Afzal. Ik weet niet zo snel hoe ik een DM naar jou toe moet sturen. Maar heb het nummer van de SIM in een Chat met jou doorgegeven.
En natuurlijk zal ik doorgeven wat het resultaat is van de test 😉

Unfortunately it didn’t work out, what we tried yesterday. Please follow this topic for new updates.

Strange! I’ve just sent you an e-mail.

I received this question a lot these days. I still need to understand why. Is our document library (getting) too complex maybe? Please let me know 🙂

However, if you ordered your NB-IoT simcard at iot.t-mobile.nl, I can assure you that your simcard is already active.

We want to save you from the simcard hassle as much as possible. All our NB-IoT simcards have the same configuration. To make sure that you can simply keep one single stock for all your different use cases/projects,

Just register the IMEI number of your module in one of your projects. Configure your module with the right settings, put your simcard in it and it should work right away.
