The maximum single text message size is either 160 7-bit characters, 140 8-bit characters, or 70 16-bit characters. Characters in languages such as Arabic, Chinese, Korean, Japanese or Slavic languages (e.g., Russian) must be encoded using the 16-bit UCS-2 character encoding (see Unicode).

Larger content (Concatenated SMS, multipart or segmented SMS or “long sms”) can be sent using multiple messages, in which case each message will start with a user data header (UDH) containing segmentation information. Since UDH is inside the payload, the number of characters per segment is lower: 153 for 7-bit encoding, 134 for 8-bit encoding and 67 for 16-bit encoding. The receiving handset is then responsible for reassembling the message and presenting it to the user as one long message. While the standard theoretically permits up to 255 segments, 6 to 8 segment messages are the practical maximum, and long messages are often billed as equivalent to multiple SMS messages. See Concatenated SMS for more information.

WAP Push is a method of sending personalised, interactive messaging or advertising to a WAP Push enabled device.

There are two efficient means of proactively sending (”pushing”) content to a mobile device: by the Short Message Service (SMS) or by the mobile device maintaining a permanent GPRS (mobile originated) session with the content server.

There are two types of WAP Push message – Service Loading (SL) and Service Indication (SI), and the experience encountered when receiving a WAP Push message varies considerably for each type, depending on the mobile device:

an SL Push message could initiate a WAP session to download additional information (such as a WAP page with images or an application) without user interaction (as long as the mobile device settings are set to enable such actions).

SL Push message functionality is technically very similar to MMS – the first the user may know is after the content has been downloaded.

a SI Push message could consist of a simple WAP page with an action that will require user interaction (e.g. a link to a page on a Web server).
(Note that no session will have been established with the WAP gateway until the user makes an action.)

The following diagram shows the transaction flow of a SI Push message.
