Sendroid Ultimate uses the same standards as your mobile phone while calculating SMS page counts.
A standard SMS message has a maximum of 160 characters. Longer messages are definitely possible, however please be aware that exceeding 160 characters will constitute a ?second? message. The end user will see this as 1 long message on their handset.
When a message is longer than 160 characters, this is referred to as a multi-part message as it contains multiple messages (or multiple-parts). The total SMS limit then becomes 153 characters per ?part? as the 7 characters are used up by invisible headers and footers which denote which part of the message is being sent (i.e. Part 1 of 2). For example: If a message is longer than 6 message parts, it will be truncated (see below).
A message can be classified as 2 types:
Standard message - contains characters from the GSM Basic Character Set (see below)
