There are several reasons why your message could be stuck on S:
- The person you're messaging isn’t connected to Kik (their phone could be turned off). However, your message will be delivered once they turn their phone on or sign into their account and reconnect to Kik.
- You or the person you're messaging is experiencing connection issues. Kik uses your existing data plan or Wi-Fi to send and receive messages so you'll need a good connection to be able to use Kik. You can learn how to troubleshoot your connection here.
