Wireless phones which receive their signals from towers. A cell is typically the area (several miles) around a tower in which a signal can be received.
Cell phones provide an incredible array of functions. Depending on the cell-phone model, you can:
• Store contact information
• Make task or to-do lists
• Keep track of appointments and set reminders
• Use the built-in calculator for simple math
• Send or receive e-mail
• Get information (news, entertainment, stock quotes) from the internet
• Play games
• Watch TV
• Send text messages
• Integrate other devices such as PDAs, MP3 players and GPS receivers
A cell phone is a full-duplex device. That means that you use one frequency for talking and a second, separate frequency for listening. Both people on the call can talk at once.
Division of a city into small cells allows extensive frequency reuse across a city, so that millions of people can use cell phones simultaneously.
Cell phones operate within cells, and they can switch cells as they move around. Cells give cell phones incredible range. Someone using a cell phone can drive hundreds of miles and maintain a conversation the entire time because of the cellular approach. Each cell has a base station that consists of a tower and a small building containing the radio equipment.

The Twitter account uses data compiled by researchers known as MalwareTech and 2sec4u, who have been mapping the spread of the malware ever since it was found responsible for a record-breaking DDoS attack against the website of cybersecurity reporter Brian Krebs. Following that attack, a hacker named Anna-senpai released the malware source code for free through a criminal hacking forum, presumably to cover their tracks as the attacks began making headlines. The malware is designed to scan for security cameras and other internet-connected “smart” devices that are still using their default passwords.
It’s still unclear who is behind the attacks, and several distinct Mirai botnets have emerged since the malware’s release. According to the researchers, the botnets have even been observed attacking one another, in some kind of bizarre cyber-dystopian turf war.
In any case, it’s probably a good idea to change the passwords on all your Internet of Things devices—or preferably keep them offline altogether.

Loads of people have much larger texting service than Data and iMessage uses WiFi first then Data while texting uses just the texting service.
The answer is so simple it may shock you. Turn off iMessage then everything goes on the texting service. It fools you because if you turn off FaceTime it is off. iMessage off just sends everything on the texting service instead of using Data service.
