Maybe, however lots of SMSCs use TON/NPIs which have no correlation to the source number format you are using (BT Cellnet/O2 being one of them). In this case the TON/NPI is manually overloaded (hence why I added the code to do that) and the source address can be what ever they tell you it should be.
In normal operation the TOP/NPI are calculated AUTOMATICALLY based on the source address you set. Therefore unless the automatic code is wrong, or you aren't manually forcing you're TON/NPIs where you need to, then the Source Address is wrong.
