Text messages seem like a sure thing, right? We tend to send them off without thinking twice about their status or delivery order. We expect them to be delivered moments after we sent them exactly as they were authored. As it turns out, SMS isn't so simple under the hood. So in this article we're going to discuss steps you can take to troubleshoot common SMS issues.
Texts are split into a series of messages at the carrier level when they exceed their character limit (160 characters for messages that contain only the GSM character set; 70 characters for messages containing one or more non-GSM characters, like emojis 👍). Here's a tool you can use to determine whether or not your message will be split, and how many segments it will be split into.
Once a message is split, it's at risk of being received out of order. For example, if the last segment in the series is smaller than the first two, it may get to the end user first since the shorter message is sent the fastest. You can get around this by pre-splitting your messages in your flows and applying a label to indicate the order in which they should be read.
