Discover everything about the iPhone 16 SIM card slot, including regional differences, eSIM support, how to insert or remove a SIM, and tips for activation and travel.
Wondering where the SIM card slot is on the iPhone 16 or whether it even has one? With Apple’s shift toward eSIM technology, the physical SIM slot situation on the iPhone 16 series can be confusing — especially if you’re comparing models bought in different countries. This comprehensive guide breaks down the latest, accurate information so you know exactly what to expect for your iPhone 16 in 2026.
Overview: Does iPhone 16 Have a SIM Card Slot?
The presence of a physical SIM card slot on the iPhone 16 depends on where the phone was purchased — it’s not the same worldwide:
- United States models: eSIM-only (no physical SIM card tray).
- International models (outside the US): Include a physical nano-SIM slot and support eSIM.
- Chinese models: Some support dual physical SIM slots without eSIM, depending on region.
This regional variation aligns with Apple’s broader strategy to adopt eSIM while keeping flexibility for markets where physical SIMs remain standard.
What Is a SIM Card Slot — and Why It Matters?
A SIM (Subscriber Identity Module) card slot holds the physical chip that identifies you to your carrier’s network. For decades, these slots allowed users to easily swap phone numbers between devices. But as technology evolves, physical SIMs are increasingly replaced by eSIMs — digital SIMs embedded directly in the phone that can be activated via software.
Physical SIM Card vs eSIM: Key Differences
| Feature | Physical SIM Card Slot | eSIM (Embedded SIM) |
|---|---|---|
| Physical card | Required | Not required |
| Carrier switching | Manual swap | Software download |
| Security | Card can be removed | Cannot be removed |
| Travel flexibility | Easy to swap in new SIM | Must provision via eSIM support |
| Dual SIM | Physical + eSIM (in international units) | Dual eSIM (US and many regions) |
Regional iPhone 16 SIM Configurations Explained
United States — eSIM-Only (No Physical Slot)
In the United States, Apple continued a trend started with the iPhone 14 and iPhone 15: no physical SIM card slot at all. All iPhone 16 models sold in this region rely entirely on eSIM technology for cellular connectivity.

The benefit is simplified connectivity and added security; eSIMs cannot be physically removed, reducing the risk of someone misusing your SIM if your device is lost or stolen. But it also means carriers must support eSIM provisioning for activation.
International Markets — Physical SIM + eSIM
Most iPhone 16 phones sold outside the U.S. still include a nano-SIM card tray alongside eSIM support. If you buy an iPhone 16 in countries like the UK, Canada, Australia, Japan, or many parts of Europe, you’ll find a physical slot for a SIM card plus the option to activate an eSIM.
Having both options offers flexibility — you can use a physical SIM for one line and an eSIM for a second, or choose two eSIM profiles if your carrier supports it.
China and Select Markets — Dual Physical SIM
In some regions, particularly China, Hong Kong, and Macau, the iPhone 16 models may ship with dual physical SIM slots, often without eSIM support. This caters to carriers and user preferences in those markets where eSIM adoption lags behind.
Where Is the SIM Card Slot on Your iPhone 16?
For models with a physical SIM tray, the location is consistent:
- The SIM slot is located on the right-hand side of the phone (facing screen up), slightly below the volume and power buttons.
- The tray is a thin, rectangular slot that you open using the included SIM eject tool (or a small paperclip).
Tip: Power off your iPhone before inserting or removing a SIM card to avoid service issues.
How to Insert or Remove a SIM Card (Physical)
If your iPhone 16 has a physical slot, here’s how to use it:
- Turn off your iPhone.
- Insert the SIM eject tool into the small hole next to the tray.
- Press gently until the tray pops out.
- Place your nano-SIM card in the tray with the gold contacts facing down.
- Slide the tray back into the phone until it’s flush.
You’ll know the SIM is properly seated when your carrier name and signal bars appear in the status bar after powering the phone back on.
Using eSIM on iPhone 16
For phones without a physical SIM slot — or as a second line — iPhone 16 supports eSIM. eSIM lets you activate your plan digitally without inserting a physical card.
How to Activate an eSIM
- Go to Settings → Cellular.
- Tap Add Cellular Plan.
- Scan the QR code provided by your carrier or enter activation details manually.
- Follow on-screen steps to finish setup.
Since eSIM provisioning requires support from your carrier, make sure they offer eSIM plans before buying an eSIM-only model.
Dual SIM Functionality: What You Can Do
Depending on your model and region:
- International models: One physical SIM + one eSIM — great for personal and work lines.
- US models: Support dual eSIM profiles — you can have two eSIM numbers on the same device.
- China models: Dual physical SIMs — helpful in markets where eSIM isn’t widely supported.
This dual capability means you can switch easily between carriers or use two plans at once for travel, business, or data optimization.
Traveling With Your iPhone 16
If Your iPhone Has a Physical SIM Slot
You can swap your home SIM for a local one when arriving in a new country. This can be cheaper than roaming and gives you a local phone number.

If Your iPhone Is eSIM-Only
You can download local eSIM plans on arrival — most carriers worldwide support eSIM activation. This eliminates the need to physically swap SIMs, but ensure carriers at your destination support eSIM ahead of time.
The Future of SIM Technology
Apple has been progressively moving toward eSIM technology — first with U.S. models starting with the iPhone 14, and now with expanding support in newer models. Experts predict that as eSIM adoption grows globally, future iPhones (like the upcoming iPhone 17 and beyond) may eliminate physical SIM slots in more regions.
eSIMs offer:
- Improved security
- Easier carrier switching
- Ability to store multiple plans digitally
However, adoption varies by region, carrier, and regulatory environment. For now, Apple’s hybrid approach with both physical SIMs and eSIM ensures global usability.
Before purchasing your iPhone 16, check your region’s specific configuration — whether it includes a physical SIM card slot or eSIM only — to ensure compatibility with your carrier and travel needs.
Summary: iPhone 16 SIM Card Slot Key Points
- US models: eSIM only; no physical SIM tray.
- International markets: Physical SIM tray + eSIM support.
- China models: Dual physical SIMs in many cases.
- eSIM activation is done digitally via settings and QR codes.
Understanding these differences helps you choose the right iPhone 16 configuration and ensures you stay connected wherever you go.
Conclusion
The iPhone 16 SIM card slot isn’t a simple yes-or-no question — it depends on how and where you buy the phone. Apple’s push toward eSIM technology reflects an industry trend, but physical slots remain in many regions to cater to traditional users and markets with slower eSIM adoption.
Whether you’re using a physical nano-SIM, an eSIM, or both, the iPhone 16 gives you flexible connectivity options tailored to your lifestyle. As always, confirm the exact specs of the model you’re purchasing, especially if carrier compatibility or travel is important to you.
