I have earlier shared details about Huawei E5377, which is available in Romania through Orange network.
Today, I have unlocked one device successfully, which was locked to Ooredoo network in Kuwait. Unlocking is the one-time job and after unlocking the device, you can use any another network provider SIM, as well as default SIM.
Currently, sub-models Huawei E5377Bs-605 and E5377s-32 are also available in various countries. Optus of Australia is also providing this device, dubbed as Huawei E5377 WiFi modem.

3. After changing the another network providers SIM on your Huawei WiFi / MiFi, switch on it. It will display “Invalid SIM” because you have used another network providers SIM.
4. Now just establish a WiFi connection to Huawei E5377 mobile WiFi router to PC / IPAD / iPhone / Android device.

Open the Settings – Dial-up – Unlock SIM card – Enter 8 digits unlock code in your Huawei E5377 router. Click OK and the device will reboot to display the new network.

Note: Don’t try to insert any free/wrong codes into your Huawei E5377 WiFi router, otherwise it will be locked permanently.
