@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.
