HI,

I purchased parallel imported galaxy s3 16g and I'm new to android phone.
Everything is working fine but s voice. After some googling, I found out that 
it often happens if it is unlocked or sim-free phone. Well, it is unlocked parallel imported product 
and the suggested solution is to go to settings>more settings>Mobile networks>Access Point Names>then select XXX(service provider in my case vodafone nz) internet. 
I followed the instruction and still get the same error message when I run s voice app.
Is there any more solutions to this problem?

Thanks.
