I travel overseas quite a bit. If this works, it will work well for me.

I will divert my primary mobile number to the Yes Life, so incoming calls are free. I can call out with this so it's a local call.

I just need to register or buy a prepaid 3G data sim card when I am overseas.

Tested it for 1 day.

Phone calls don't always come through to me. some of my sms'es also don't get through to the other person.

In my opinion, it's not good enough as a primary phone. It is stupid to pay RM 30 monthly for this service. YTL will be stupid to insist on a monthly commitment since it's a good service, just not good enough yet.
