Issue
When the Remote Alarm Manager (RAM) sends an SMS message via GSM modem to a mobile phone, the message is truncated—the end portion of the message is missing.

Cause
The issue occurs due to the length of the message being sent. SMS messages have a character limit of 160 characters. If the message exceeds this limit, it may be truncated or not delivered in full, depending on the mobile carrier and device.
This is especially common when:
- The message type is set to Long Message (multi-line descriptive format).
- The Index Title or Point Title used in the message is excessively long.
Resolution
To prevent message truncation, consider the following actions:
-
Use Shorter Message Types:
- Change the message type from Long Message to Normal or Short Message.
-
Shorten Titles:
- Abbreviate long Index or Point Titles.
- Example: Change
"Temperatures"to"Temps".
-
Review Message Content:
- Ensure the total message length does not exceed 160 characters.
