I also don't need to ask... Should I contact you on WhatsApp, FB, Wechat, Hangouts, Twitter or whatever the shiny thing of the day is. Just give me your phone number.
Indeed. It also works reliably internationally. China has blocked Facebook and WhatsApp, but SMS still works.
Doesn't iMessage work internationally? iMessage just works. It's beautiful, especially when everyone you know has an iPhone. And I'd say China blocking some services is more China's fault than that of WhatsApp (terrible name).
Yes, it works internationally. .. As long as you have a data connection.
