Mobile phones, called mobile phones or wireless phones, are usually called mobile phones. At first, they were just a communication tool. In the early days, they were commonly known as "mobile phones" and can be used in a wide range of portable telephone terminals. They were first developed from battlefield mobile phones manufactured by Bell Laboratories in 20 12.

Mobile phones are divided into smart phones and non-smart phones. Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones. Most non-smart phones and smart phones use the CPU of British ARM company.
