[Q] Samsung galaxy camera voice call in singapore

view story

http://forum.xda-developers.com – Hi, im new to this forum and im kind of desperate as i lost my phone tomorrow, so in need of a phone asap. i stumbled upon this samsung galaxy camera yesterday but the salesperson told me it does not have voice call function unless you use skype and stuff. but skype is not being used frequently in singapore. so is there any apps which i can use to make normal voice calls in singapore? i read through the forum, there are apps like GrooveIP but when i check on it, it only supports in US or Canada. thus need some advice on any apps that i can use for normal voice calls. thank you (HowTos)
