Quick answer

It syncs over Wi-Fi or your paired phone's data. If that phone uses Openline, your Watch syncs seamlessly.

What to do while abroad

  1. Keep your Watch paired to your phone (Bluetooth on).
  2. Set Openline as your phone's Cellular Data line.
  3. All Watch traffic that would normally cost cellular data now goes through Openline.

What won't work

  • Making phone calls directly from the Watch when your phone is out of Bluetooth range.
  • Standalone Watch-only cellular data.
