Check your exact Google Pixel Watch 4 LTE
A model name can cover different regional hardware and connectivity variants. This two-minute check confirms your exact device.
- 1
Open Settings on the device or its companion app.
- 2
Open the cellular, mobile network, connections, or SIM menu.
- 3
Look for Add eSIM, Add cellular plan, or a similar option.
- 4
Open About or device status and look for an EID. If the device supports dialling, *#06# may also show it.
What confirms compatibility
If Add eSIM is visible and an EID is present, the device has an eSIM module. You should still confirm that it accepts plans from other carriers.
Carrier unlock is a separate check
An eSIM-capable device can still be locked to the carrier that sold it. Ask that carrier to confirm the device is unlocked before installing a travel eSIM.
Regional and carrier exceptions
Manufacturers note that eSIM service can vary by country, carrier, and model variant. Always check the exact device before purchasing.
Only LTE models support eSIM. The watch must be activated with a compatible carrier; full talk, text, and data service may require the same carrier as the paired Android phone.
