Ensuring SMS within the Character Limit

As a mobile user, we tend to check our SMS inbox every day to explore the latest messages waiting for us. SMS is a convenient communication tool that allows us to connect with people regardless of their location and without facing internet barriers.

Compared to other communication tools, SMS is highly effective, with a 98% open rate, and it is also cost-effective. By using a text messaging service to send business SMS and MMS, we can efficiently broadcast messages to hundreds of customers at once.

What is the character limit for SMS?

The length of a text pattern is 160 characters, including spaces, numbers, letters, and punctuation marks. An SMS can certainly exceed 160 characters; it will, however, become a'multi-part message’ and each message may be charged separately depending on your mobile carrier's pricing plan.

When your message gets longer and becomes a multi-part message, the character limit changes from 160 to 153 characters per part. This is because additional data is required to create a sequence of messages. The remaining seven characters are used for invisible headers and footers.

The text message body limit is 5000 characters, which creates 33 ‘parts’

The character limit for Unicode messages

Customers would like to experience the look and feel of their language. Unicode SMS allows you to send messages in any foreign or regional language other than English. Unicode can represent any character in SMS but occupies more characters than English. As such, Unicode messages are limited to 70 characters and 2000 characters after concatenation.

(Example, Word: hello

Unicode encoded:00000068000000650000006c0000006c0000006f)

The best practice to keep SMS character limits

1) Use a tiny URL instead of a long URL.

Maximum uses tiny, short URLs in message content rather than full, complete URLs. A complicated URL will lead to exceeding the character limit, but we can convert the same URL to tiny or shortened, which is the same as the full URL.

2) Put an eye while copy-pasting

It's best not to copy message content directly from a word processor because it may contain hidden Unicode characters that could cause issues. Instead, copy the content from a plain text editor before pasting it into the Hub. This will ensure that any unwanted Unicode characters are removed.

3)Effective use of templated messages

Rather than using the copied message, creating a predefined template with effective short words will help to communicate with customers within the character limit and avoid using junk characters.
