Common Uses of Dual-SIM Devices:
- Personal and Business Numbers: Use one SIM for personal calls and the other for business.
- Different Network Providers: Use one SIM for better coverage and the other for cheaper rates.
- Travel: Use a local SIM card for better rates while keeping a home SIM card active.
SIM slot 1 is a critical component in mobile devices, especially in dual-SIM configurations.
