eSIM availability may vary by country or region. Some devices originally sold in mainland China and certain other markets may have different SIM configurations. Verify that Settings → Cellular/Mobile Data contains “Add eSIM.”

Which plan it supports

Standard is single-network coverage; Max Coverage is the broader multi-network option (see pricing for the difference). Based on iPhone XS Max’s cellular bands (model A1920/A1921):

Bands verified against https://support.apple.com/en-us/111880 on 2026-08-16. This confirms hardware capability, not whether a specific unit is unlocked or blacklisted — always confirm with your carrier’s own IMEI compatibility check before buying a plan.

Software support

iPhone XS Max is capped at iOS 18 (confirmed 2026-08-16) — the manufacturer has moved on to newer OS versions for other devices.

Still receives security-only patches on iOS 18 (e.g. iOS 18.7.9, released 2026-05-11) even though it will not receive iOS 26 or later.

Before you buy
