Hi can anyone help me to decode this SMS? Or to describe what each of the hexa numbers means. I know that this SMS was send to 700 (PDU 07F0) via SMSC 421905303303 (PDU 249150033330), but what are all the other?... Any ideas?

The SMS PDU format is documented in ETSI GSM 03.40 specification, which can be downloaded from http://www.etsi.org.

If you want to take a few minutes to read that spec, and attempt a decode by yourself ... I'd be happy to answer questions.
