What is imessage?

In Apple's iOS5 mobile operating system, there is a new function and term, which is iMessage. For Apple Empire, some devices have GSM communication function, such as iphone, which can send short messages through telecom operators, or send and receive short messages through GPRS data connection through third-party apps such as WeChat and Whatsapp. The latter, because it is based on data connection technology, you don't charge according to the amount of data you use, just like SMS. For today's smart phones, many people add the option of data packets when accessing the network, so that they can get at least 2-30MB of free data traffic every month, which is the so-called "free" SMS (unless sending pictures or audio files, sending information generally requires 1KB, while 65433).

For Apple, because some devices don't have GSM function, such as iPad or iPod, such devices can still connect to the Internet through Wi-Fi, thus having data interaction ability. At this time, it can communicate with others through WeChat or Whatsapp. Apple has also seen this. It hopes to provide a functional software built into the iOS operating system, so that future Macs, IPhone, iPad, iPod and even all Apple devices can communicate with each other as long as they can connect to the Internet. Therefore, iMessage was born. If you want to understand it well, you can think of it as a WeChat that can't send voice messages.

However, iMessage is slightly different from WeChat. IMessage can only be used on Apple devices. In other words, if you are currently using a Windows computer, an Android phone or a WP phone, you cannot use this function. In the foreseeable future, closed Apple seems to have no intention of migrating iMessage to other platforms.
