Dual Card Dual Standby Single Pass (dual-SIM devices only)
Your device supports only dual card dual standby single pass, which means you cannot use both SIM cards for calls or data services simultaneously.
- When you are on a call using SIM card 1, SIM card 2 cannot be used to make or answer calls. If someone calls SIM card 2, the caller will hear a voice message similar to "The subscriber you dialed is out of the service area" or "The subscriber you dialed cannot be connected for the moment, please try again later." The actual message will vary by service provider.
- When you are using SIM card 1's data service, SIM card 2's data service will be disabled.

You can go to Settings > Wireless & networks > Dual SIM settings, and enable Enable call forwarding between SIMs to avoid the conflicts mentioned above.
