0000  GSM 7 bit default alphabet; message preceded by language indication

    the first 3 characters of the mssage are a two-character representation of the language encoded according to ISO 639, followed by a CR characters. The CR character is then followed by 90 characters of text.

0001  UCS2; message preceded by language indication

    The message starts with a two GSM 7 bit default alphabet character representation of the language encoded according to ISO 639. This is padded to the octet boundary with two bits set to 0 and then followed by 40 characters of UCS2 encoded message.

    An MS not supporting UCS2 coding will present the two character language indentifier followed by improperly interpreted user data.

If Bit 5 = 0, the text is uncompressed

If Bit 5 = 1, the text is compressed using the compression algorithm defined in 3GPP TS 23.042

If Bit 4 = 0, indicate that bits 1 to 0 are reserved and have no message class meaning

If Bit 4 = 1, indicate that bits 1 to 0 have a message class meaning
