• Dual Standby vs. Dual Active: Some devices support dual standby (only one SIM active at a time), while others support dual active (both SIMs active simultaneously).

Security and Tracking

• Device Tracking: In case of theft or loss, knowing the IMEI numbers of both slots can help in tracking the device.
• Blacklisting: If a device is blacklisted, both IMEI numbers can be reported to prevent unauthorized use.

Troubleshooting
