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 @Ivan4172

according to the datasheet PON_TRIG is pulled down to GND by default. So I would not expect any difference in module behavior if you connect PON_TRIG to GND, but it seems to be unnecessary.

Yes, it is my understanding that if PON_TRIG is left alone (using the internal pull-down) that the module works normally and should not reset.

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

Does anyone have experience using RAI (Release Assistance Indication) with LwM2M?

I can think of three cases when this is useful:

Observe notifications (both CON and NON) LwM2M 1.1 Send operation Close connection (de-register and after bootstrap-finish)

In other cases the device does not know if the server wants to send more.

@Kevin-van-Bakel-0 you can absolutely still experiment with the T-Mobile NB-IoT network with those SIM cards, but they are part of a different service and are not usable in conjunction with IoT Creators. We have our own SIM cards with a specific profile that allows us to authenticate the SIMs and manage connections. IoT Easy Connect Start is pure connectivity and does not offer access to IoT Creators’ data-as-a-service, so you can still connect to the internet with the card via the APN “iot.t-mobile.nl” (specification), but if you want to try out IoT Creators’ platform, then you will have to get a SIM from us.

If you are still interested in using IoT Creators and not a public APN for pure connectivity, just get in touch with us and we’ll get you a SIM for your Starter plan. We offer the Starter plan with one SIM for free when you register, so you can test everything and if you have already created an account with it, but skipped the SIM ordering, because you thought that your IoT Easy Connect Start SIM would work for it, then we can easily manually send a SIM to your preferred address for use with IoT Creators. I just need a short ping from your end what you would like to do and you address.

@Lauwie007

There are legal limitations imposed on us what we can commercially offer - but that might change in the future. However, then we also probably need to change the commercial offering of the public APN, because it’s basically raw connectivity what you would source from us.

As said the public APN is for TESTING ONLY. We are not planning on closing it down any time soon, but maybe we might at one point. So we cannot guarantee a continuity of this APN forever. Most likely it would change if we can commercially offer it at one point! Maybe it make sense if we have a quick call about it so I understand your requirements a bit better.

We have a partnership for NB-IoT with A1 Slovenija in Sovenia, so this was not intentional and will be fixed.
My previous suggestion unfortunately does not work properly, so contacting us directly is the best way to order in this case.
Sorry for the confusion.

Should be fixed now!

@florian-duecker I’ve revolved the issue by using the off the shelf OpenVPN option T-Mobile offers: Summarized for others&future:
The IoT Easy Connect LTE-M connectivity assings a private IP-range (in my case 10.42.242.0/24) to the sim-cards.
The IoT Easy Connect Portal>Settings>OpenVPN describes how to setup an OpenVPN connection to T-Mobile.
Activating this tunnel on my server enabled me to ping the devices and to carry out various connectivity test.

@Lucas05: I’m sorry, but I don’t really understand the question. What do you want to know? Are you asking if LoRa and Sigfox are the same? The answer to this is: no, not at all. Yes, both are providing LPWAN connectivity, but the technology and business models behind it are quite different.

If you are interested to learn more about this, you can find a detailed comparison of the technologies (+ NB-IoT) here: https://iot.telekom.com/resource/blob/data/492968/e396f72b831b0602724ef71056af5045/mobile-iot-network-comparison-nb-iot-lorawan-sigfox.pdf

I hope that helps 🙂

Florian

@florian-duecker That’s great. Thanks!
