Hello, It has been a week now that I have an android phone. I love this nifty phone with android apps. Please tell me which android apps are best for VOIP calls which is stable and has good call clarity. I am planning to tell me friends who live abroad to download the same app so that we can call each other frequently. Before the android app, I was using Skype for desktop. For some reasons my phone cannot download Skype app, it says I have restriction, weird. Your help will be greatly appreciated.
