A:AnswerNo, it won't work with Sprint currently. I was previously on Sprint before I switched to this phone, but I had to switch to T-Mobile. Depending on your area, T-Mobile and AT&T are great carriers, just check the coverage map for your area first.
A:AnswerYes and No. Yes, with google apps like Hangouts Dialer with your google phone number or Skype. It does not give enhanced AT&T wifi calling like on the iPhone. Keep in mind this phone was designed to work with AT&T but not designed for AT&T.
A:AnswerIt is an unlocked phone and yes it should work with international sim cards. I would confirm with the manufacturer before heading out to Philippines just to be sure.
