Hello brother, this issue is occurring because you are using an Indian-variant Samsung device. Merely changing the region in settings does not override the core regional lock of Samsung Wallet and the Google Play Store. Here are the solutions to resolve your problem:For Samsung Pay/Wallet: Samsung Wallet availability is hardcoded into the device's original firmware region code (known as CSC). An Indian-variant phone will generally not accept Saudi Arabian bank cards directly. To completely fix this, you would need to change your phone's CSC by flashing the official Saudi Arabia (KSA) firmware using a tool called Odin. However, please note that this process is advanced and carries a risk of data loss.For Google Play Store Apps: To download Saudi-specific apps, your Google Play country must match your current location, which requires adding a local Saudi payment method. The easiest workaround is to create a completely new Gmail account while connected to the local Saudi network. Add this new account to your Play Store, and you will be able to search and install all Saudi-based applications without any issues.
