LG L3 (E430) VOIP app abroad?

[missmouse3]

im going to Thailand in a couple of weeks & was thinking about downloading a VOIP app such as Tango to help keep costs down while im away. Anyone recommend a good one?
Ideally Id like to be able to set up a way to call my landline answer machine while im abroad for free to pick up any messages. My phone is unlocked so I can also get a local sim but then nobody will have my number?

There are a whole lot of good ones but my favorite is viber because you can change the call and message tones (helps me hear incoming calls and messages)


Other good ones you can try are: ICQ, kakao talk and line.
