All modem devices support 2 types of SMS message format – Text & PDU (Protocol Data Unit). Depending on what SMS message forma is set, the AT command format to send and read SMS messages will vary. Text format is straight forward to use. PDU format gives more control over the content of the message such as encoding type (other language character set), how long the message is valid, protocol identifier (fax, voice etc),
\nreply path etc.<\/p>\n
