Login Based on SIM Card Info

We are developing an iOS app where users can log in and access the application. If the user closes the app on the same device, they will remain logged in the next time they open the app. However, if the user changes the SIM card on the same device and then tries to access the application, the app should prompt the user to log in again due to the SIM card change.

Please let us know the best solution to achieve this requirement and whether it is feasible to manage the login state based on the SIM card information.

No, I don't think this is feasible. iOS apps don't have enough accessess to this kind of information.
