Hello,
This is the intended behaviour. When a specific event occurs, it triggers a SIM switch. Once the SIM switch is triggered, an SMS/Email notification is sent. The device then switches to a different SIM card and attempts to establish a mobile connection with the operator, which might take some time.
If you prefer to receive SMS/Email notifications only when the device successfully establishes a data connection with the operator after the SIM switch, you can set up an event reporting rule with the type: mobile data and subtype: connected. This rule will be triggered when the mobile data connection is established. You can customize the notification message by adding additional information, such as the current SIM being used, the operator’s name, etc.
Kind Regards,
