Regional differences
| Model | Market | eSIM | Physical SIM | Storage | Evidence by field |
|---|
Model/market mapping and specifications use the verification evidence listed for each field. A market with no local evidence reads as pending — never another market's configuration.
Cellular bands by model
Bands and sales regions are proved by Apple's worldwide mapping page. That does not prove carrier compatibility in any market.
Verified offers
No current verified offer is available.
How do I identify my model?
- Check model information in Settings or on the original box.
- Match the hardware model code, not only the product name.
- For imported phones, check the original market. No IMEI or serial number is required.
Will this phone work in your country?
Band and SIM support alone do not prove carrier compatibility. Verify 5G, VoLTE, eSIM activation and lock conditions for the exact model.
