E176 Voice Unlocking

[inflock]

Hello;

I am using Huawei E176 and i tried to unlock voice feature in my modem. So i followed this thread which saying we can freely unlock our modem's voice feature. But it is saying everytime that you have insufficient credits while it has to be free. Any body can help about this.. If it is not free to enable voice feature how many credits should i buy for this.

Thanks for your assistance.

Voice activation is only free if modem unlocked by dc-unlocker.
If not, activation needs 4 credits.
