Find the identifiers
Open Settings, General, About. The value beside Model Number is the part number. Tap it to display the A-number, such as A2633. Apple explains this switch in its model-number guide. Keep the full part number on the lot list as the unit’s recorded identifier, but use the A-number for the checks below.
Check each offered unit
- Record both identifiers. In Settings > General > About, record the part number, then tap it to reveal the A-number.
- Match the A-number. Use Apple’s Identify your iPhone model page to find the countries or regions associated with that hardware.
- Check the SIM type. Use Apple’s current SIM guide and its China mainland, Hong Kong, and Macao exceptions. Match the exact model and purchase market.
- Check cellular bands. Use Apple’s cellular page for the exact A-number, then confirm the required bands and eSIM activation with the destination carrier.
