How to find if a user changes his SIM card from his phone(iPhone). we can find “mobileCountryCode,isoCountryCode,mobileCountryCode and mobileNetworkCode” through programatically these are not specific to particular SIM, these are specific to operator, is there any way to identify when user changes his SIM card from his iPhone.
Please any one help me on this.
Thanks in advance.
You are able to sign up for a notification using
subscriberCellularProviderDidUpdateNotifierinCTTelephonyNetworkInfo
However you will only be notified if the swap occurs while your app is running. You will still be unable to detect if the user changes the SIM to another SIM from the same operator when your app is not running.
