The “00” value here lets the phone set the message reference number itself. When this alphabet is used, eight characters of the message are packed in seven octets, and the message can consist of up to characters instead of characters in 8-bit data coding.
Although spefification changes are ancient version 6. Partners Contact us Sitemap. The number itself must always start with a country code and must be formatted exactly according to the E. Using the unknown format i. Setting the TP-RP bits turns on a feature which allows to send a reply for a message using the same path as the original message.

This octet specificatiln optional, see bits 4 and 3 of the first octet. You will then need to enter the destination number for the SMS message.
The following 3 octets contain a relative validity period in hours, minutes and seconds as the 3rd to 5th octet of time format.
However, a GSM Message Waiting Indication group of DCS values can set or reset flags of indicating presence of unread voicemailfaxe-mail or other messages. Support Knowledge base Technical support. This behaviour was designed ssms older mobile phones which don’t understand UDH; such mobile phones might display the UDH as a jumble of strange characters; if the first character after UDH was S,s Return CRthe mobile phone would rewrite the mess with the rest of the message.
Alphabet indication Unspecified message handling at the MS Default alphabet 7 bit data coding in the User Data reserved. The length of the phone number is odd 11therefore a trailing F has been added, as if the phone number were “F”.
The value of 1 in the bit 7 of the first octet indicates that TP-VP functionality indicator extends to another octet. In this case the number must adhere to the mobile operator’s dial planwhich means that international numbers must have the international prefix 00 in most countries, but in the USA before the country code and numbers for long-distance calls must start with the trunk prefix 0 in most countries, 1 in the USA followed by a trunk speciffication.

Treat this as any previous element in the sequence, hex 82 represents specifcation The Validity Period parameter value indicates the time period for which the short message is valid, i. User data length, length of message.

In time the Class 2 is supported, if you choose Class 1 or Class 3 the short message is treated the same way as a Class 2 message. In the first case, the representation of time is as follows:.
The content of the message its text when the message specifciation not a binary one is carried in the TP-UD field. The following octet is a relative validity period as described in the Relative Validity Period Values table.
The phone is now ready for sending and receiving SMS.
How to do the transformation from 7bit septets into octets is shown here.
