Unlocking Airtel Huawei E173u USB Data Card Modem Online Without Software


First of all I’d like to apologize for not posting the trick to unlocking Airtel Huawei USB E173u Data Card Modem before now as most readers of this blog have been inquiring how and I have always promised to post it, hope am not late and hope you will forgive me for not posting it in time.

Please do not get bothered with the term ‘data card‘ its same thing with the word ‘modem‘. More so, the basic reason why I will be using the Airtel E173u modem here as the case study is because that’s actually the kind of modem I use and I only post tips I have tried out successfully and am currently using my cracked E173 USB data card on my PC with other Sim without any problem.

Requirement To Unlocking Airtel Huawei E173 Modem

Like I have stated in the title of this post, this tip doesn’t require you using any software rather it requires you unlocking it online.

Like I have earlier stated in a post I wrote regarding unlocking most huawei modems, you just need to get the unlock code via the USB Modem’s IMEI number unlike zte modems that require softwares like DC-Unlocker and sorts.


1. Your Airtel E173u IMEI number
2. Internet Connection On Your PC or Mobile Device
3. A Laptop Or Personal Computer.

  • First, insert your modem into the USB port Of Your PC with another network sim card in it.
  • Wait for the interface to come up and you will be asked to enter the unlock code, Airtel E173 data card usually gives a trial code of 10.

  • Next, visit Huawei Data-card Unlocking Page here and Enter your USB Modem’s IMEI Number(15 digits) in the imei input box provided and click Calculate.

  • Copy the unlock code(8 digits) because that’s basically what you will be needing.
  • Navigate back to your Airtel data card interface and type in that unlock code and click Unlock.

You have successfully unlocked your Airtel E173u modem without paying a single dime.

Can this tip work in Unlocking Other Models Of Airtel USB data cards?

Well, like I earlier stated, I use the above kind of modem(E173u-2)and the above tip was how I unlocked mine, whether or not this tip can unlock other models like E172, E1731, E173cs-1, E1150 etc is what I really cannot ascertain but I would advice you give this tip a try, if its same huawei type of modem then it should work and at same time I would love to hear your feedback via the comment form.

    Good day, I visited the HUAWEI MODEM UNLOCK CODE CALCULATOR and i got the needed codes. But while i inserted the Airtel Huawei E173u-2 Modem, it gave me the following comment “INVALID SIM DETECTED. PLEASE CONTACT CUSTOMER CARE.”

    1. Adeniyi Samuel says

      In this case you will be needing a DC-Unlocker account with credit to be able to unlock that because that modem is obviously a new one from airtel unlike mine that am still using now and unlocked for totally free using the above tutorial.

  3. JAson statham says

    It’s true Bamidele, All these kind of techniques are not successful they can provide temporary results but not permanent, There are many unlocking experts available on the internet, They can provide you best solution.
