Regardless the etymology of the word phone, nowadays calling and sending sms is not the main usage of the device. Most people only make calls on emergencies only. In fact, calling when you don’t need something urgently is often considered rude. Anyway, that can also be done with FaceTime, WhatsApp, telegram, Skype, etc. Internet is far more important. When people make contracts with carriers most often than not they choose it based on the data and not minutes or sms. If you pay attention to ads by the carriers you’ll see that data is always the highlight, that’s what phones are actually used for these days.
