My Apple Watch sports model paires with my iPhone 6 running iOS 8.3 successfully and I am able to receive messages from my friends. However, when i try to send and respond SMS (green messages), it is not working at all. The green bar goes across, and just hangs over there. The process won’t completes and then failes to send message. I notice that all received SMS are not stored in my list of messages. Any way to fix the issues?
If you can’t send or receive SMS with the apple watch and the messages are stuck, try any of those tips to resolve it.
1. toggling the Send as SMS and restarting the watch.
In Settings/Messages, Send as SMS as this is already on. Toggle this option to off and then restart your wearable device.
2. From the Phone settings, go to switch the SMS to be on.
3. If you are using 2-step verification, that should cause the issue. You need to re-generate the key for iMessage and FaceTime, and type it when the watch promptes you for the iCloud password.
4. Another method
The first step is to unpair your apple watch.
Within the iPhone settings, go to messages > send and receive, make sure that you have ticked your mobile number.
Finally pairing two devices again.
5. Disable the iMessage completely on your phone
On your iPhone, toggling iMessage to off to disable it, then send and receive some test SMS on Apple Watch to check if it is fine.
