          Check whether its connected in the 2g only or WCDMA network.This might solve the problem.

      Hai Nitin, Try uninstalling the Mobile partner and re-install again or use the Airtel net connect software to connect to internet.

    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…

      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.

      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

      You can choose any plan like 1Gb or 2Gb according to your need.Contact Customer care for details.

      Make sure that the huawei e303s aircel driver is installed properly.If not download the driver and install it again.
      If the problem is not solved you can download the original huawei e303s firmware and try it again.
