App Rejected – iPhone-Only App Using SIM Binding (SMS) Being Tested on iPad

We are facing an issue with App Store review and would appreciate some guidance.

Our application is designed strictly for iPhone devices only. The app includes a SIM binding mechanism that requires sending an SMS from the registered mobile number for device verification. This functionality depends on the physical SIM capabilities available only on iPhone devices.

However, during the review process, Apple is testing the app on an iPad device. Since iPads generally do not support sending SMS from a physical SIM (especially Wi-Fi models), the SIM binding process fails, which is resulting in app rejection.

We have:

Configured the app deployment target for iPhone only.

Set the device family to iPhone in Xcode.
