i am developing a software application to send sms. I have been successfull in sending small sms. but when comes to large sms (i.e)larger than 160 characters i have to break sms in segments. But i am not finding what segment codes to insert in each segment of the original sms so that it can be reassembeled at destination handset.

I will be thankfull to any reply.

1 solution

You would need to add an user data header (UDH) to the sms to do this. Have a look at these links:[^][^]

Another solution could be to send it as an MMS instead of an SMS if the message is over 160 characters. This might even be cheaper because you send a single message.

Good luck!

Yes, by my knowledge it is necessary to have a gsm modem or some sort of sms server/gateway that delivers this service.
