Problem

Custom SMS messages that are longer than 160 characters (or 70 characters if UCS encoding) are missing a link to the full text message. If confirmation is enabled in the message, the limit is 120 characters so that the confirmation link can be included in the message. (Notifications > + New Notification).

Root Cause

This issue occurs if you enable the Use custom SMS message option in a notification and do not check the Add Web Page Message option in the Message template.

Solution

When creating a custom SMS message using the Use custom SMS message parameter, a link to the remainder of the message in the form of a custom Web page can be appended to the SMS message by checking the Add Web Page Message parameter in the Message template.
