WhatsApp is better than calling and texting because:<p>1. Audio quality is great<p>2. Messaging is more rich and can send files<p>3. No roaming - it works everywhere.<p>And if WhatsApp gave you a real USA phone number (instead of registering with your current, carrier-provided number) it would have benefits like:<p>1. A phone that works anywhere - with Wifi or mobile data. No roaming<p>2. You could call/text anyone with or without WhatsApp (because you have a real number)<p>3. It's just a better messaging experience: multi-device, send files, richer functions<p>... Would you cancel your expensive wireless plan and use (or port your number to) WhatsApp as your primary number?<p>If not - what would be your concerns?
been doing that just fine for some 10years. have a few minutes early on just for emergencies out of 3g data coverage. but now its only data.<p>you can do that today and without whatsapp/facebook if you learn to do very basic online research and read a couple pages.
