English technical guide: Android New Phone RCS Not Receiving Old Device Disable

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. Identify the exact device, OS version, carrier/plan and the condition that triggers the symptom.
  2. Check the lowest-impact settings first and change only one variable at a time.
  3. Separate device settings from carrier/account-side restrictions.
  4. Retest data, voice, SMS and 5G independently where relevant.
  5. 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.
