Huawei has released new MiFi hotspot router dubbed as E5573. It is available in the U.K. and other countries locked to a particular network.

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.

Now your Huawei E5573 Mobile WiFi Router is unlocked forever.

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.

Some of the devices which I have already unlocked:

  1. E5573s-320 (MTN Uganda)
  2. E5573Bs-320 (TMN Portugal)
  3. E5573s-320 (Lao Laos & IRAN MCI)
  4. E5573s-320 (Smart Philippines) with Firmware 21.316.03.00.238
  5. E5573s-508 (Personal Argentina)
  6. Orange France 4G Airbox Huawei E5573
  7. Orange Poland E5573s-320
  8. E5573s-856 (MTN Ivory Coast) firmware
  9. Idea E5573
  10. E5573s-606 Spectranet Nigeria
  11. E5573s-320 EE (UK) and Optus (Australia)

You can reach me at with solution and your service charge details. Would e best if you can do it for me using VNC or TeamViewer. Await to hear from you soon. Thanks !

  28. Hi,

    I have the E5573s – 320 device. Currently locked to Airtel Nigeria.

    WHen I insert another network sim, it show:

    “The device has been locked. Contact your ISP to obtain the SIMLOCK code. Enter the correct SIMLOCK code to unlock the device. If the remaining number of unlock attempts is 0, the device will be permanently locked.”

    How do I unlock this?

  29. Hi Kamlesh,

    I’ve a Optus E5573s-606 wifi router.
    Can this be unlocked ? If yes, how do I unlock it ?
    How much do I have to pay for the unlock code ?

  30. Hi Kamlesh,

    I followed the instruction in your link.
    In step 3, ie “Firmware code you can generate from Universal Master Code tool or comment with model and IMEI to get it”, I ran the code tool, but only generated unlock & flash code. How do I get the firmware code ?
    Btw, I’m currently not in Australia, can I still unlock the router ?

  31. Hi. I also have a MIFI from HUAWEI E5573 which I purchased for full price from THREE in Ireland, but now I am in another EU country, trying to use it with THREE provider of this country. It does not work. 🙁 I read that the THREE in Ireland locks it without any reason. Could you pls help to unlock it. If you could help with the unlock code, that would be great.
    My version of the MIFI is as this:
    Model: E5573s- 320
    IMEI: 866162025707325
    Thanks a lot again.

  32. First I tried to install web partner for Windows 8 from your site. It did noT find the port. Then I tried to update with Download Huawei E5573s-320 Firmware (Normal). It did not work out either. It says, network change has detected. no connection. And error message says, Error 10- did not find the port.
    Could you pls advice what other steps I should take to resolve the problem?

  33. hi again. i wrote here before, maybe it did not pass through.i kinda unlocked the mifi, through the code you provided, meaning now it can see the new sim, but the problem is that it now requires an unlock code for sim. i tried again the code you gave me. it did not pass through. no matter what number i put in, it requires a code to unlock the sim ( the sim are all unlocked, i can use them with different devices). it means it is still mifi which needs to get unlocked. thanks.

      • Unlock device
        This device is locked . To obtain the SIMLOCK code, please contact your network operator.
        After the correct password is entered, the device will reset automatically.
        However, if a wrong password is entered for ten times, the device will be locked permanently.

        SIMLOCK code:

        Remaining attempts: 7

        • Three attempts were for the code you gave, and pin and puk codes of the sim ( the last 2 ones were in vain though, the code has nothing to do with the sim, its device need to be unlocked.).

          • I think I changed the firmware. Sorry I am not really very good at it. What I did is that I downloaded Huawei_E5573s-320_Firmware_21. something and plugged the router to the computer with Irish number. That way it started rthe upgrade process of the MIFi and requested code from me, and used the firmware code you gave. and it later said upgrade done successfully. Then I installed my new number and again connected the MIFI to the comp. Now it requests sim unlock code.

                It seems I did not the change the firmware afterall. But it did conduct upgrade, and afterwards it started to see my new coverage, but requests unlock code. But after upgrade it also stopped working with its Irish number. As I said before now it asks for unlock sim code, no matter what number I insert in it.
