Why should activate services again after switching SIM cards?

1. After switching SIM cards, you need to activate Find device, Mi Message, and Xiaomi Cloud sync again.
2. The services we provide work normally only when the SIM card they are associated with is in service. New SIM cards need to be verified in order for the services to become available again. To verify your SIM card, Xiaomi needs to send 1 or 2 paid messages to your carrier.
