Flash & Prio SMS

Flash SMS and Prio SMS+

These are special types of SMS text messages which are displayed directly in the home screen of the recipient’s cellphone. PrioSMS+ is announced with a double ring tone and is sent as higher priority to maximize attention.


Text-to-Speech SMS

eCall converts written text messages into speech. The system calls up the recipient and “reads” the message text. If a message is not called up the first time, it is sent twice more at five-minute intervals.
