SMS character limit

A single SMS has a character limit of 160, this is a standard limit across all UK mobile phone providers.

If your SMS template exceeds 160 characters, it will be split into separate messages. For example, an SMS with a character count of 161 will be split into 2 messages, the first containing 153 characters and the second containing 8 characters.

We'd recommend using a free character counter 🔗️ to ensure your SMS template suits your preferences. Tags in SMS templates also need to be considered, for example, a tag for a customer name will differ per SMS depending on the length of the name.
