Does eSIM work on iPhone bought in Japan?
iPhones sold in Japan (SIM-free or unlocked models) support eSIM normally. SoftBank, KDDI/au, and NTT DOCOMO locked iPhones from Japan may have restrictions on adding third-party eSIM profiles for voice — however, Japan Wireless is a data-only eSIM and does not use the voice/SMS slot. Data-only eSIMs generally work even on carrier-locked Japanese iPhones.
Can I have dual SIM with a Japan eSIM on iPhone?
Yes. iPhone supports Dual SIM with your physical SIM (home carrier) + eSIM (Japan Wireless). Your home number receives calls and SMS via the physical SIM. Japan Wireless eSIM handles all data. In Settings → Cellular, set 'Cellular Data' to Japan Wireless and 'Default Voice Line' to your home SIM. This way you can still be reached on your home number without paying roaming data charges.
What if my iPhone shows 'No Service' after installing the Japan eSIM?
First, confirm the Japan Wireless eSIM is set as the Cellular Data source: Settings → Cellular → Cellular Data → select Japan Wireless plan. Then toggle Airplane Mode on and off to force the phone to re-register with a local tower. If still no service, check that Data Roaming is turned on for the Japan Wireless plan (Settings → Cellular → Japan Wireless plan → turn on Data Roaming). Contact [email protected] if the issue persists.
