    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?

    • Gowtham April 6, 2012, 1:40 pm

    • Gowtham May 2, 2012, 4:12 am

      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.

      After Buying Huawei data card, you can use any sim card service which has a better 3G Reception in your area.I am using Airtel and Aircel SIM in my datacard.
      You can choose any plan like 1Gb or 2Gb according to your need.Contact Customer care for details.
