Brother driftmeister, I am happy for you now that you had decided to opt for YES. I am sure if you compare the voice rates with other telcos like Maxis, Digi, Celcom [you pay through your nose], it's definately the cheapest rate in whole Malaysia. As for the wireless, it's still very fast & cheap too & you still get the rebates.
