How to Stay Connected on Your Watch While Traveling

Smartwatch eSIMs are tied to number-sharing plans from your home carrier, so travel data eSIMs can't be installed on the watch. Instead, install a travel eSIM on the paired phone — the watch stays connected through Bluetooth or Wi-Fi and keeps notifications, maps, and apps working abroad.

Frequently Asked Questions

Does the Pixel Watch 3 support eSIM?

Yes — the cellular/LTE model of the Pixel Watch 3 has a built-in eSIM. The Wi-Fi/GPS-only model has no eSIM. The eSIM is provisioned through the paired phone's companion app with a plan from your mobile carrier.

Can I use a travel eSIM on the Pixel Watch 3?

No. Smartwatch eSIMs only work with number-sharing plans from your home carrier — travel data eSIMs like MyeSIM's cannot be installed on a watch. Install the travel eSIM on your phone instead; the watch will use data via Bluetooth/Wi-Fi from the phone while you travel.
