Instinct solar disconnects from iPhone when there is no phone signal, have difficulty connecting again.

Hello JAG5151

I am sorry to hear you are having trouble getting the watch paired with the phone. For this, I would recommend the following steps: 

1. Ensure the phone's OS is on the latest version
2. Uninstall the Connect Mobile app
3. Clear the phone cache and history (Settings, Safari, Clear browsing history and website data)
4. Ensure the watch does not appear in the phone's Bluetooth menu. If it is, please remove the device
5. Powercycle the watch and phone. To do this, hold the Light button until this shuts off. Then power on again
6. Reinstall the Connect Mobile app
7. Try the pairing again ( Be sure there are no other Bluetooth enabled device nearby)
8. When pairing, sign into the app, and allow this to walk you through the pairing
