English technical guide: Android Private DNS Custom Hostname No Internet

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. Record the current network state before changing settings.
  2. Test once with VPN/Private Relay/custom DNS disabled to isolate the network layer.
  3. Check whether the issue occurs on Wi-Fi, cellular, or both.
  4. Review per-app exclusions, carrier apps and tethering restrictions separately.
  5. Restore one setting at a time so the cause remains identifiable.

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.
