Why this rule existsrationale

Every segment is billed and delivered separately, and long concatenated messages are reassembled unreliably across carriers — so a ten-segment message costs ten times as much and is the most likely thing in your programme to arrive broken. Reviewers read extreme length as a sender who does not understand the channel.

How to fix itremediation

Shorten the message and move detail behind a link on your own domain. Aim for one or two segments — 160 GSM characters per segment, or 70 if the message contains any non-GSM character.
