Texting is also used to communicate very brief messages, such as informing someone that you will be late or reminding a friend or colleague about a meeting.
As with e-mail, informality and brevity have become an accepted part of text messaging.
The GSM in the US had to use a frequency allocated for private communication services (PCS) – what the ITU frequency régime had blocked for DECT – Digital Enhanced Cordless Telecommunications – 1000-feet range picocell, but survived.
American Personal Communications (APC), the first GSM carrier in America, provided the first text-messaging service in the United States.
This was part of ISDN (Integrated Services Digital Network) and since GSM is based on this, made its way to the mobile phone.Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone.The possibility of doing something is one thing, implementing it another, but systems existed from 1988 that sent SMS messages to mobile phones usually messaging from one mobile phone to another mobile phone.As with emailing, in the 2010s, the sending of short informal messages has become an accepted part of many cultures.This makes texting a quick and easy way to communicate with friends and colleagues, including in contexts where a call would be impolite or inappropriate (e.g., calling very late at night or when one knows the other person is busy with family or work activities).
