Make sure your E5578 router is connected to a constant power supply / fully charged.
2. Just insert a nonacceptable Network sim (other than default) on your E5578.
3. Now, switch ON the device, it will display “Invalid SIM” because you have used another network provider's SIM.
4. Now just establish a WiFi connection with Huawei E5578 to PC / iPad/ iPhone / smartphone / tablet (I prefer to use Windows PC).
5. After establishing the WiFi connection with E5578 and PC, log in to your device’s dashboard using the admin username and password. Go to Advanced Settings – SIM Settings – Unlock Device – Unlock Code / SIM Lock / NCK.
6. Enter the correct code which is provided by modemsolution.com.
