"Only the Specified SIM/USIM can be used on this device" on Huawei E173 bu-1 Airtel

[mvmkandan]

Hi Experts,

I bought Huawei E173 bu-1 Airtel 3g Model on last week and its working for airtel Sim, I tried to unlock the dongle by using dc-unclok and frameware

After that When I see the status in DC-Unlocker client, the status shows as

Model : Huawei E1731
IMEI : 86XXXXXXXXXXXX
Voice feature : enabled
SIM Lock status : [B]UnLocked [/B]
Wrong codes entered : 10 (unlock attempts left : 0)

But When I insert Tata Docomo GSM 2g SIM on the dongle, it shows "Only the Specified SIM/USIM can be used on this device" error occurs..

Any one please let me know whether my modem has unlocked? Whats the solution to use another SIM?

Thanks
Veera

What sim was inside modem when you detected it on dc-unlocker? To get correct lock status there must be not airtel sim inside the modem during detection.
