SMS Message Sending Guidelines

SMS Message Length

SMS messages have a character limit, which restricts the amount of information that can be sent in a single message. Historically, one SMS message was limited to around 150 characters, with messages exceeding this limit being sent in separate parts. Case Manager allows you to send messages exceeding 150 characters in multiple parts, but there is still an overall length restriction. One SMS part equates to roughly 150 characters, and sending more parts will require more credits.

How Big Can My SMS Messages Be?

If you are uncertain about the permissible size of your SMS messages, you can inquire with the IIZUKA Support Desk or the designated support contact in your organisation.

Checking Message Length

Automatically generated SMS messages by the system are designed with the length limitation in mind and hence, will not exceed the part limit. However, if you modify the content of the SMS, you might need to verify the length of your message. Currently, there is no built-in function in the system for this, so you will need to check the size of your message outside the system.

Content of SMS Messages

SMS messages are encoded using a character set known as GSM. This set includes all numbers, letters, and most standard punctuation.

Supported Characters in SMS

• Letters: A-Z, a-z
• Numbers: 0-9
• Punctuation: !, #, ', ", %, &, \, (, ), *, ., ?, +, -, /, ;, :, <, =, >, ¡, ¿, _, @, ,
• Currency: $, £, ¥

Avoiding Unwanted Characters

Characters not included in the GSM character set can cause the SMS part limit to be halved. To prevent this, follow these steps:

• Enter your message directly into the system
• Refrain from copying and pasting content from other applications like Microsoft Word
• If you need to copy and paste content from other applications, first paste it into Notepad to remove any unusual characters.
