i have unlocked my data card. Have set new profile in apn also. but my reliance sim is connecting only on 2g it shows edge not 3g and the speed is also pathetic.
Check whether its connected in the 2g only or WCDMA network.This might solve the problem.
thanks a lot Gowtham !
worked like a charm 🙂
I am glad this post was helpful . Welcome.
Hi, is this same trick can be applied on MTS MBLaze ZTE model – AC2746. Please do le me know thanks.
hey, i am trying to unlock my AIRTEL 3g data card. i could unlock the different network SIM but not able to install “Huawei E-173 Firmware” downloaded from the link u provided.
can u tell me what could be the problem?
I have unlocked Huawei EC150. I have updated firmware also and installed new mobile partner. But mobile partner does not detect my device (it is not showing device in choose device…)
Please help…
Hai Nitin, Try uninstalling the Mobile partner and re-install again or use the Airtel net connect software to connect to internet.
Hay after unlocking can i use airtel net conecting software with other sim cards. can I?
Ya you can use it with other sim cards.
Install Modem Drivers Manually…u will find in c/programfiles/mobile partner/drivers
Hi Gowtham, I think first I need to enable the Sim slot of the device. EC150 is CDMA device so we can not use Airtel…
Can you please tell me how to enable sim slot?
my e173u-1safaricom customized modem won’t be updated by the Huawei E-173 Firmware. if fails at the ‘downloading program part’, giving an error message—”updated failed”. any other option please?
The same message came for me too.Try removing the data card and then insert it and quit any programs using it and then try updating the E Firmware.Hope this helps.
Hi, i generate the unlock code then entered it. but it seem to be wrong code. i have only 8 attempts left. i am using E173.
I unlocked my modem only by trying more than 10 times,i also had my sim locked.We can unlock the SIM if we know the PUK number.Make sure you have entered the serial no of your modem correctly and the type is chosen a huawaii in the options tab.Do contact us for further help via fb http://www.facebook.com/mytechshoutfans

Hi Gowtham, is this the latest dashboard for E173U-2, if not where can I find it?
second, is this the latest firmware update for the E173U-2?
Thanks
when i am installing firmware it is asking for password.what should i put it there
When asked for password try typing your unlock code generated or try to enter the pin lock code number of your sim card if it din’t work.Enter Firmware unlock code in the password field,it will be the best choice.
Thanks

i want to unlock my e1731 huawei airtel data card…
am not getting satisfying comment from this post.. will this surely works?/

I unlocked it using this method successfully without any problems.Even if you cannot unlock it , your 3g modem will be usable. If you get any errors just try another unlocker that might work.You can unlock it easily with this tutorial , just be sure you are using the correct firmware update and code generator.
Thanks
Hey Gowtham,

can i know which is the best 3g modem among huawei,micromax and zte and which can be unlocked easily from aircel.
I have unlocked my huawei modem easily.It will be a better option to buy a huawei 3G wireless modem separately and buy a sim you want and use it.. 🙂
but in india unlocked modems are available in micromax,,huawei 3g modems are always locked with a particular operator isnt it?
and the cost of locked 3g modems is less compared to unlocked modems…
Huawei unlocked modems are also available in india.If not available in your area you can go for Micromax 3g datacard or other brands.Thanks
