Hi Iain, We have found that we have 154 chars per SMS when using concatenation.
So far the only answer I've received to explain why we can get 154 chars per SMS and not 153 chars per SMS is, if you are connecting directly to the SMSC, they may not keep to the spec exactly and some SMSCs allow more chars per concatenated SMS. We are using the Kannel variable concatenation = true and max-messages and its working well. So I'd be interested to know for your Mobile Operators if you can get 154 chars per concatenated SMS or just 153 chars? Rgds
