iPhone eSIM Storage — Official Limits
Apple doesn’t officially publish exact eSIM storage numbers, but practical testing and documentation reveals:
| iPhone Model | Max Stored eSIMs | Max Active Simultaneously | Physical SIM |
|---|---|---|---|
| iPhone XS/XR | ~8 eSIMs | 1 active | 1 nano-SIM |
| iPhone 11/12 | ~8-12 eSIMs | 1 active | 1 nano-SIM |
| iPhone 13/14 (international) | ~8-12 eSIMs | 2 active | 1 nano-SIM |
| iPhone 14 (US) | ~8-12 eSIMs | 2 active | eSIM only (no physical SIM) |
| iPhone 15 series | ~8 eSIMs | 2 active | 1 nano-SIM (outside US) |
| iPhone 16 series | ~8 eSIMs | 2 active | 1 nano-SIM (outside US) |
iPhone 16 — Key Facts
- Max stored eSIMs: Approximately 8 (practical limit may be slightly higher)
- Active simultaneously: 2 eSIMs active at the same time
- Physical SIM: Still included on international models (UK, EU, Asia)
- US model: eSIM-only — up to 2 eSIMs active from stored profiles
What Counts Toward the eSIM Limit?
Every installed eSIM profile counts — even expired, deactivated, or unused plans. Your iPhone accumulates them until you manually delete old ones.
For frequent travellers: after 8-12 countries, you may be prompted to delete an eSIM before adding a new one.
Managing eSIM Storage on iPhone 16
See all stored eSIMs:
Settings → Cellular
You’ll see all stored eSIM profiles listed below your primary lines. Each is labelled (often by the eSIM provider’s name — e.g., “Airalo – Thailand”).
Delete old eSIMs:
Settings → Cellular → [eSIM name] → Delete eSIM
Annual eSIM cleanup: Delete expired travel plans to maintain storage space.

Renaming eSIMs for Easy Management
Default eSIM names are often generic. Rename for clarity:
Settings → Cellular → [eSIM name] → tap the name at top to edit
Suggested naming convention:
- “Airalo – Thailand – Apr 2025”
- “Airalo – Asia Regional – May 2025”
- “Home – UK EE”
Clear naming makes it easy to identify which plan to activate when you arrive in a new country.
Using 2 eSIMs Simultaneously on iPhone 16
With 2 eSIMs active, you can set:
- Primary line: For cellular calls and default mobile data
- Secondary line: Active but using secondary data settings
Best travel setup:
- Line 1: Home SIM (physical or eSIM) — for home calls/SMS
- Line 2: Airalo travel eSIM — for local 4G data
Set the Airalo eSIM as Default for Mobile Data to use local rates rather than expensive home roaming.
Can iPhone 16 Store More Than 8 eSIMs?
Practically, some users report storing 12-15 eSIMs before hitting any limit. The ~8 figure is conservative. Apple likely has a firmware limit higher than commonly cited. Until you get a “cannot add eSIM” prompt, continue adding — then delete old plans.
