Hello everyone, I am in dilemma for choosing prepaid or postpaid . hope someone could help me out . (prefer digi, if hotlink or maxis got good plan good price can change too) . also let me know which plan is best for me to choose , thanks in advance for all recommendations

Now I am using prepaid for years and I found that the call rate is extremely high (I am using easy prepaid, but not really utilising it...).

My requirements :
1) 3G data but 50-500mb should be enough, just using whatsapp and search LYN when not at home WiFi.

2) Decent call rate (maybe 15sen/s or 12sen/s or any better one??).
And let me know which plan of telco have best call rate to others telco: Ie: Digi to Maxis , Maxis to Digi .

3) Decent SMS rate to other telco . (maybe 10sen/msg ??)

I will also taking the free talktime and free SMS (like 100 or 200 free) into consider .so plz do let me know also. And is this free call and SMS can be applied on other telco ??

Sorry for lengthy question . thanks in advance for everyone that would help me out
