Hi Bruno, I have some troubles with concatenated SMS (very long messages). Long SMS (8 bit) are used by Alcatel and Siemens phones: there are messages up to 40 SMS, but I have troubles also with messages of 13 SMS. I tested two Alcatel ringtones, the first composed by 3 SMS, the second composed by 13 SMS. First ringtone is received correctly, second ringtone is not received. I don't know where is the matter. I also tried to let kannel split the message and I tried splitting the message and using splitted messages in kannel (waiting 30/60 seconds before every message sent). The message wasn't received correctly in both cases. I used these PDU with my Nokia 7110 and message is always received, so I think there are no bug in Alcatel phones. The answer is: why 3 messages are sent correctly and 13 messages no? And why it's all ok with Nokia 7110 (using same PDU) ? thx
