text messaging was the most widely used mobile data service, with 74% of all mobile phone users worldwide, or 2.4 billion out of 3.3 billion phone subscribers, at the end of 2007 being active users of the Short Message Service.In countries such as Finland, Sweden and Norway, over 85% of the population use SMS.This was part of ISDN (Integrated Services Digital Network) and since GSM is based on this, made its way to the mobile phone.
and three large cable-TV companies, owned 49 percent of APC. One factor in the slow take-up of SMS was that operators were slow to set up charging systems, especially for prepaid subscribers, and to eliminate billing fraud, which was possible by changing SMSC settings on individual handsets to use the SMSCs of other operators.
The Sprint venture was the largest single buyer at a government-run spectrum auction that raised $7.7 billion in 2005 for PCS licenses. SMS is available on a wide range of networks, including 3G networks.
Hence there is no "development" in the US in mobile messaging service.
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.
Governmental and non-governmental organizations use text messaging for communication between colleagues.
