Using international SMSCs
I get a lot of questions from users using a GSM operator without an UCP SMSC. To use other international SMSCs you have to use your telcos normal international prefix for the call, not the + prefix you usually use on international calls on your phone. E.g. to use Telias SMSC at +46740930000 (Sweden), use 0046740930000 if 00 is your operators international prefix.

The same goes for the reciever of the message, but here you have to use the SMSC operator's international prefix. For the SMSC above that is 00, so to send a message to an UK phone use 0044 and the phone number. The number you want as sender you pass the normal way, the message will be recieved with no changes on this number.
