This list ranks the countries of the world by the number of mobile phone numbers in use. As an important caveat, this list does not provide the number of mobile phones in use. It is common for each SIM card has a separate phone number, so phones with multiple SIM cards will have multiple phone numbers. As another caveat, some mobile phone numbers may be used by machines as a modem, such as intrusion detection systems, home automation, or leak detection, and some numbers may be used as a local micro-cell.
