The iPhone 16 series makes eSIM installation faster than any previous iPhone — and in the USA, there is no physical SIM slot at all. Here is the complete 2026 guide for all four models.
iPhone 16 eSIM Specifications
| Model | eSIM Profiles | Active Simultaneously | Physical SIM |
|---|---|---|---|
| iPhone 16 (USA) | 8 stored | 2 active | ❌ eSIM only |
| iPhone 16 (International) | 8 stored | 2 active | ✅ 1 nano-SIM + eSIM |
| iPhone 16 Pro / Pro Max | 8 stored | 2 active | International: nano + eSIM |
With 8 stored eSIM profiles, you can pre-install eSIMs for Japan, Europe, USA, Thailand, Australia, China, Korea, and UAE — all ready to activate without re-scanning when you visit each destination.
Step-by-Step iPhone 16 eSIM Installation
Step 1 — Confirm Phone is Unlocked
Settings > General > About > Carrier Lock. Must show No SIM Restrictions.
Step 2 — Get QR Code on Second Screen
Display your purchase email QR code on a laptop or tablet. You cannot scan a code shown on the same phone you are installing to.
Step 3 — Open Settings > Cellular
Settings > Cellular > Add eSIM
Step 4 — Tap Use QR Code and Scan
Camera opens automatically. Scan the QR code in 1-2 seconds. iPhone 16 camera sensor makes this the fastest QR scan of any iPhone model.
Step 5 — Confirm and Name
Confirm the plan details shown. Name the line (Japan, Europe, etc.). Tap Done.
Step 6 — Set Cellular Data to Travel eSIM
Settings > Cellular > Cellular Data > select your travel eSIM line
Step 7 — Enable Data Roaming on Travel eSIM
Settings > Cellular > tap travel eSIM line name > Data Roaming > ON
Without this step, the eSIM installs but will not connect to foreign networks.
iPhone 16 Exclusive Feature: eSIM Quick Transfer
iPhone 16 supports eSIM Quick Transfer — moving an eSIM from your old iPhone to your new iPhone 16 without contacting your carrier. This works for your main carrier eSIM. Travel eSIMs purchased from us do not need this — they install via QR code directly.
