Have you heard of Fring.com? Skype is the most famous years ago but after some comparison the rate is more expensive than Fring.com.
Call to Singapore cost about 4sen (EUR0.9 x RM4.4 per Euro)... as low as Telekom Fixed Line call charges in Malaysia.
Just download the apps into your iPhone or Smartphone or Andriod phones, buy credit with credit card and start calling.

Google Voice also a good choice for those who likes Google's product, the rate is better than Skype and Fring, it also support calling from mobile BUT unfortunately Malaysia is not supported for "calling from Mobile", you can only call from computer by install the Voice within Gmail.
