Tekstiviestikeskus

Tekstiviestikeskus, also known as the Text Message Center, is a service provided by mobile network operators in Finland to facilitate the sending and receiving of text messages (SMS) to and from landline phones. The service was introduced to address the growing popularity of mobile phones and the need for communication between mobile and landline users.

The Text Message Center operates by converting text messages into a format that can be transmitted over the public switched telephone network (PSTN), which is the traditional landline network. When a mobile phone user sends a text message to a landline number, the message is routed through the mobile network to the Text Message Center. The center then converts the message into a format suitable for transmission over the PSTN and delivers it to the recipient's landline phone.

Conversely, when a landline user sends a text message to a mobile phone number, the message is routed through the PSTN to the Text Message Center. The center converts the message into a format suitable for transmission over the mobile network and delivers it to the recipient's mobile phone.

The Text Message Center service is widely used in Finland, with millions of text messages sent and received each day. It has become an essential part of the country's telecommunications infrastructure, enabling seamless communication between mobile and landline users. The service is provided by all major mobile network operators in Finland, ensuring widespread availability and reliability.
