Wait After Boot
A delay is often necessary to ensure that the radio and telephone modules are fully activated before the app starts. Typical values range from **10 to 40 seconds**, although some devices may operate with zero delay. If your Dual SIM device does not block calls effectively, consider increasing this wait time.
The Submode setting allows control over the hardware features of the device. It's crucial to select the appropriate submode to ensure network functionality remains intact after a reboot. Reboot your device whenever a submode change occurs.
For smartphones using an MTK chipset, select Submode 1.
You can check the current status of services in the "About" section of the settings menu; a green indicator for SIM1/SIM2 means everything is functioning correctly.
