I’ve recently been using the Raspberry Pi Hat along with the CORE dashboard. The system that was deployed is no longer needed and I would like to remove the asset and disable the SIM and stop all billing. Can you provide instructions for how to accomplish these tasks.
There is no option to remove assets. When you inactive your SIMs, there will be no cellular data usage, and no monthly fees will be charged for inactive SIMs, so you will not be billed in any way. In short, inactivating all of your SIMs will suffice for your needs.
