Apple watch radomly drops cell service

We understand the importance of being able to connect with your children, @chasndav04. 

We have a few questions we'd like you to answer to help us get to the bottom of things: 

• Are they losing service in one specific location or is this happening every time they're away from your home's network? Sharing this will let us know if they're traveling in a low coverage area. 
• What's the signal strength on the devices? The network signal strength is displayed in the Control Center as green dots. The more the better. Depending on the network connection, the apple watch may be unable to receive calls. 

Since you've already tried power cycling/resetting the devices, the next step would be to perform a factory data reset. This will reset all settings to their defaults and erase all data stored on the devices, including the contacts, messages, and music. When you perform a factory data reset, a backup of the watch will be stored on the paired iPhone.

• From the clock screen, press the Digital Crown/Home button then select the Settings app.
• Select General, then scroll to and select Reset. 
• Select Erase All Content and Settings, then scroll to and select Erase All to confirm.

Keep us updated on how this information helps! We're here for you.
