Message Centre Number

Hey there people.... I was just wondering if anyone knew any way of finding out the message centre number of an incoming message... I mean an sms or something...? Coz when i go to view the messag details the message centre number soesn't appear...
Cheers

Easy, you just have to know what's the operator of who sent you the message. Call them and ask for it! Or ask directly to your friend! There's no other way of knowing it!
