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).Messages could be sent and received on ISDN phones, and these can send SMS to any GSM phone.
When Radiolinja's domestic competitor, Telecom Finland (now part of Telia Sonera) also launched SMS text messaging in 1995 and the two networks offered cross-network SMS functionality, Finland became the first nation where SMS text messaging was offered on a competitive as well as on a commercial basis.
GSM was allowed in the United States and the radio frequencies were blocked and awarded to US "Carriers" to use US technology.
Hence there is no "development" in the US in mobile messaging service.
All messages and content sent via the services are automatically turned into "dust" after 24 hours.
If you want a more immediate expiration of messages, you can set content to delete as soon as it's been opened and read.
