Hi everyone,
I’m trying to activate LTE on my Galaxy Watch 6 Classic LTE from my Pixel running GrapheneOS and keep running into errors.
Current setup:
Device: Pixel 8 with GrapheneOS (latest stable)
Profile: Owner profile (main)
Accounts: No Google account signed in
Installed apps: Galaxy Wearable, Galaxy Watch 6 Manager (plugin), Samsung Accessory Service — all installed in the Owner profile
Goal: Activate the LTE / mobile plan on the watch without linking Google or Samsung accounts to my device
What happens:
When I try to set up the mobile plan in Galaxy Wearable, the process fails.
Initially I got Error code 0 (connection/provisioning failure).
After some retries and adjustments, I got Error code 4001 (server/operator rejected the LTE activation).
What I’ve learned so far:
The carrier must whitelist both the watch’s IMEI and the device initiating the provisioning. If not, Error 4001 occurs.
My current configuration (Owner profile, no accounts, no Play Services) means I may fail Samsung’s validation and the carrier’s provisioning checks.
Question:
Has anyone here successfully activated LTE on a Samsung Galaxy Watch LTE model with GrapheneOS?
If so, did you:
Use Play Services in sandbox mode?
Activate LTE on another certified Android phone first, then pair the watch with GrapheneOS afterwards?
I’m looking for a privacy-friendly method, but right now it seems LTE provisioning for Samsung watches is tightly locked to certified devices and accounts.
Thanks for any insight!
