There are a couple of reasons why your messages may not be sending and are stuck on S:
- The person you're messaging isn’t connected to Kik (maybe their phone is off). 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 some connection problems. Kik uses your existing data plan or Wi-Fi to send and receive messages. You'll need a good connection to be able to use Kik. You can refresh your connection by toggling your Wi-Fi and data connections off and on in your phone settings.
