hi @Filip9679 !
yes you will be able to change it later, you can always end your starterkit project and create another one with a different type, and if you have any issue doing that you can write me here and i will do it for you 😉
I suggest you to chose the option “Via webhooks and off-the-internet”, so that you will be able to use iotcreators services later if you like.
If you only plan to only connect to public ip addresses though, registration is not even mandatory, you cna just insert it in your device and start using it.
You will have to setup the correct apn to work with public or iotcreators services.
To connect to public ip addresses, use apn internet.gma.iot
To connect to iotcreators services, use apn scs.telekom.tma.iot
Sim card works in many different countries, you can see a list here: https://docs.iotcreators.com/docs/roaming-mobile-iot-networks
Hope this helps!
