Device-specific technical record
| Device | Google Pixel Watch 4 LTE |
|---|---|
| Model | GWSQ2 / G1KAW (NTT Docomo-supported model number) |
| SIM/eSIM | Built-in eSIM |
| LTE | Google Japan specification does not publish an individual LTE-band list on the cited page. |
| 5G | 5G not supported (official spec lists 4G LTE / UMTS) |

For special-purpose devices such as kids phones, feature phones, routers, tablets and watches, SIM recognition, APN, voice/SMS, number-sharing services and vendor-specific features must be evaluated separately.
English technical guide: Pixel Watch LTE Carrier Number Share
This page is the English companion to the corresponding SolQvia Japan guide. It preserves the diagnostic boundary used by the Japanese article: distinguish device settings, carrier/account conditions, radio compatibility and service provisioning instead of treating them as one problem.
Recommended diagnostic order
- Identify the exact device, OS version, carrier/plan and the condition that triggers the symptom.
- Check the lowest-impact settings first and change only one variable at a time.
- Separate device settings from carrier/account-side restrictions.
- Retest data, voice, SMS and 5G independently where relevant.
- Use destructive actions such as reset, SIM deletion or account removal only after confirming the recovery path.
Important boundary
Do not treat a single successful check as proof of full compatibility. SIM recognition, mobile data, voice, SMS, eSIM provisioning, APN and 5G can succeed or fail independently. Preserve a known-good state before factory reset, eSIM deletion or account removal.
