If you're not planning to use some SIM cards immediately, you can easily suspend those SIMs. From the following month, you will not get charged a monthly invoice for the suspended SIMs.
When you are planning to use your SIM, you can activate it using the SAP IoT Connect 365 UI.
Refer to the article: Suspending and Activating a SIM for details of how to suspend and activate SIMs.
