This type of communication, like SMS, is probably familiar to every modern message, and everyone knows about the disadvantages of this. The fact is that each text message costs money, and by no means the smallest, and this message itself has a limit on the number of characters, so writing in Russian more than one sentence is unlikely to succeed. This type of connection, which, obviously, is already very outdated, and now everyone can see this. This became possible due to Google, which launched a free “killer” of the usual SMS. This is a new technology, and is called such RCS (Rich Communication Services). With its help, you can once and for all forget about any restrictions when using this type of communication, even during trips around the world.
The American corporation Google understands better than others that it is impossible to continue using SMS as one of the main types of communication, as this significantly slows down technological progress. Against the background of all this, in order to solve such a problem, the “search giant” considered it necessary to develop an alternative to the usual text messages, which he did. So, in particular, the “killer” of SMS familiar to everyone turned out to be launched, which can be used without any charge. To use RCS messages, support for such should be implemented at the level of the operator’s equipment, and many of them have already implemented it. All of them allow their customers, including when roaming, to use this type of communication for free. 
Cellular operators earn money by providing other services, because many now consider the support of the RCS protocol to be an advantage for which it is worth using the services of a telecommunication company. It is already possible to use the new method of communication, instead of SMS, on phones running the “green robot”, but you just need to download it from Google Play or update it using an application called Android Messages. Following this, you will need to run this program and agree to use the new protocol. Then, after that, everything will work automatically, and everything will work even without an Internet connection, including Wi-Fi. This makes the new form of communication as affordable as SMS, but it also contains a number of important advantages.
So, in particular, users can receive reading reports, due to which it is easy and simple to understand whether the interlocutor has read the message or not. In addition, there are no restrictions on the length of RCS messages, which favorably distinguishes them from SMS, because this allows you to send at least whole texts, and for all this you will not have to pay a single penny. One of the features of the new technology is that it requires much less resources from the telecom operator for its work, and that is why it is much cheaper and easier to send such messages than regular text SMS. It is expected that over the next two years, more than five dozen telecom operators will implement support for RCS (Rich Communication Services).
Google previously banned popular Android apps that millions of people use.
