It is a dedicated number that is responsible for the delivery of message sent on a mobile phone, just like APN (Access Point Name) is responsible for the uploading and downloading of packet data. Without configuring the APN on an internet-enabled smartphone one cannot browse the internet. The message center number (SMSC) likewise if not configured properly will hamper text messages sent from delivering.

Actually, no one would change it. But in case, you should check it when you meet text messages not sending.
