SMSC and its protocols
SMSC is short for "Short Message Services Center". The European Telecommunication Standards Institute (ETSI) has approved four (4) protocols. SMPP is the most widely spread protocol in the business. However we have listed all four approved protocols below:

SMPP: SMPP is a protocol created by SmsForum.net.
UCP/EMI: UCP/EMI is a protocol created by LogicaCMG
CIMD2: CIMD is a protocol created by Nokia
OIS: OIS is a protocol created by SEMA



Please note that it's not necessary to connect directly to an SMSC to send your messages. Almost all SMS-providers offers simplified protocols, for example via:

HTTP GET/POST: By just making an HTTP GET or HTTP POST request to the provider you can send an SMS. This is the easiest technique to implement to existing websites.

SOAP: SOAP is short for "Simple Object Access Protocol" and is a common protocol used for more then just mobile messaging. Basically it's a lightweight XML-protocol.
