What is smsc?

SMSC, which stands for Short Message Service Center, is a network element in the mobile telecommunications infrastructure that is responsible for the routing, forwarding, and delivery of SMS messages between mobile devices. The SMSC also stores messages when the recipient device is unavailable, before attempting delivery again at a later time.

SMSCs play a crucial role in enabling SMS communication between mobile subscribers, as they ensure that messages are delivered accurately and efficiently. They also handle message encoding and decoding, as well as message format conversions when necessary.

Additionally, SMSCs play a vital role in managing the delivery of bulk SMS messages, which are often used by businesses for marketing, customer communication, and other purposes.

Overall, the SMSC is a critical component of the SMS ecosystem and is essential for the reliable and timely delivery of text messages between mobile devices.
