Why do reading text messages and reading e-books generate traffic?

Reading short messages will generate traffic because: mobile phones often receive some short messages, which will include some Internet addresses. If you click on these addresses, the mobile phone will connect to the network and visit these websites, thus generating traffic (when mobile data is turned on). If you use your mobile phone to surf the Internet, watch e-books, videos, or listen to songs online, traffic will be generated. It is recommended that you download and save related e-books, videos, songs and other files on your mobile phone in advance, and then watch or listen offline on your mobile phone (without surfing the Internet), so as not to generate traffic.
