I don't quite get your question.
I'm gonna assume that you need help setting up your phone to make 3G(Video) Calls and also to browse WAP and WEB sites via 3G.
If that's your gripe, then all you need to do is this:
Find out your phone model
and
log on to: www.maxis.com.my -> Choose "MAXIS 3G"(top right tab) ->"All About 3G"->"3G Phone Configuration"
Choose your phone, input number, choose service: e.g. MAXIS 3G WAP GPRS & MMS
You should get the settings pushed to your phone. Accept, let it install, and viola.....You're 3G enabled.
