English technical guide: Google One Downgrade Cancel Over Storage Limit

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

  1. Separate device storage from cloud-account quota.
  2. Check Trash/Recently Deleted and ownership before assuming deletion freed quota.
  3. Confirm whether sync mirrors deletions across devices.
  4. Protect local originals before disabling sync or removing an account.
  5. Re-check quota after the service finishes processing deletions or plan changes.

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.
