Rating meaning: “Strongest fit” generally indicates the original selling carrier or direct primary-source support. “Major-band fit” means key radio bands are present, but it does not prove VoLTE/IMS, SMS, emergency calling, carrier aggregation, 5G SA or support eligibility.

Safe order when moving this phone to another carrier

  1. Confirm the model number. Check Settings/About or the regulatory label. Do not rely on the product name alone.
  2. Confirm the SIM path. Verify physical SIM versus eSIM support before ordering or reissuing a line.
  3. Check the target carrier's key LTE bands. Missing a low-band coverage layer can affect indoor and rural usability even if service connects in some locations.
  4. Provision the line. For eSIM, add and enable the carrier-issued profile first. APN values are not eSIM activation credentials.
  5. Check data, voice and SMS separately. Data working does not prove VoLTE/IMS voice support.
  6. Check 5G last. Verify n77/n78/n79, plan eligibility, coverage and NSA/SA conditions after LTE is stable.

Japan vs overseas model boundary

See the Japanese source record for the exact wording. Technical markers: 3516 eSIM SIM.

When importing or reusing an overseas model in Japan, also verify the exact regional model, Japan regulatory compliance/technical conformity, emergency-call behavior and carrier support. Do not infer these from a visually identical model sold in another market.
