Nowadays, the most used technology to perform phone calls by advanced mobile operators and phone service providers over the Internet, such as Skype, is Voice over IP ( VoIP? ), also called Internet Telephony, which transforms voice into data packets that travel through the Internet to its destination. Given this, it is technically possible that we do not need mobile network operators to process our phone calls if we can be connected to a giant Wi-Fi network and have Wi-Fi enabled mobile devices. |
