The point of the text message: brevity.
Our recommendation is to always pare down information in scripts so that the interaction can carry a lot of the intention: real conversations with real people. On top of that, carriers can actually enforce a text limit when sending information out, based on the amount of characters they allocate as 'text length'.
While some of the largest carriers in the country are able to maintain cohesive messages even when we get a little wordy, be aware that some will break your message up if you exceed the recommendations below. This would most commonly look like 2+ messages being sent out in reverse order than intended, like so:
Using emojis makes this even more difficult because it changes the amount of allowed characters just by existing in a sentence.
Basic text character count before carriers split the message: 160 characters
Text messages with emoji before carriers split the message: 70 characters
If you’re worried the message will be split, the best practice is always to check on how many characters you’re at as you’re composing with an online character counter, such as this one.
