Total size of an SMS

[ricky001]

Hi,

I want to build up a storage for storing two SMS. So I need to know the maximal size of an SMS. By "SMS" I mean a 140 byte-long Payload.
When I read through the specification I can not see such statements.
What I have until now would be:
- Payload: 140 bytes
- header-byte: 1 byte
- number: 14 bytes (stored as String)
- arrival date: 20 bytes (stored as String)

did I miss something here?

Hi, Ricky.
It seems that you have missed several parameters

TP-Protocol-Identifier - 1 byte
TP-Data-Coding-Scheme - 1 byte
TP-User-Data-Length - integer

Then, regarding number - in fact you have two numbers, originator number (TP-OA), which is 2-12 bytes including length and type, and SMSC address (RP-OA).
And timestamp is 7 bytes, not 20.

I hope this was helpful,
Nina

P.S. For more information please check 3GPP TS 23.040.

Thanks for telling me the specifications ( I didn't know about that ETSI-site)
