SMSC number stands for Short Messaging Service Center Number. When a user sends any SMS, this SMS goes through a SMS service center before it is finally diverted to its destination. Think of SMS service centre as a gas station service stop on your way to your final destination. Since, SMS service centres are different for each service provider, service center number for each service provider will be different. If this number does not match with what you may see on the screen, one will have to contact customer/tech support to get the dialing sequence to set their SMSC number. One does not need the SMSC number set up to receive SMS. Without this SMSC number, one will not be able to send a single SMS!
