As you might already aware that without unlocking, you can not use any another carrier SIM. Unlocking is one-time work and after unlocking the Huawei E5573 4G mobile WiFi router, you are free to use any SIM.
How to Unlock Huawei E5573 4G Mobile WiFi Router to Use Another SIM?
1. Make sure your Huawei E5573 Mobile WiFi Router is fully charged.
2. Just insert a nonacceptable Network sim card on your Huawei E5573 WiFi router . (You have to use another network provider sim, which is currently locked to).
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 E5573 gateway with your PC / IPAD / IPHONE / Android smartphone.
5. Connect your device with PC and login to the device’s dashboard and go to Advanced Settings – SIM Settings – Unlock Device – Enter Unlock Code – Click on Apply.
Open up E5573 router Settings – Dial-up – Unlock SIM card – Enter 8 digits unlock code. Click OK and the device will reboot to display the new network.

Note : Don’t try to insert any free codes into your Huawei E5573, otherwise your it will be locked permanently. Unlock code of E5573 can not be generated by IMEI, means you need to change the firmware with universal firmware then only SIMlock can be generated. Furthermore, unlocking process is different for submodels of E5573. Hence, we have covered separate post for each.
