The iPhone 16 and its SIM card setup are key points of interest for buyers, especially those who frequently switch carriers or travel internationally. If you buy your iPhone 16 in the US, it will be eSIM-only, but if you get an iPhone elsewhere in the world, it will have a SIM card slot.
With Apple increasingly shifting toward eSIM technology, many are wondering if the iPhone 16 still supports a physical SIM card or if it follows the trend set by its predecessors of being eSIM-only. In fact, eSIM-only iPhones are sold only in the USA, while iPhones elsewhere in the world still have a physical SIM card slot. But what about the iPhone 16? Apple has been gradually phasing out physical SIM card slots in the US, starting with the iPhone 14. We’ll explain a little about that in this guide, alongside explaining whether the iPhone 16 lineup is expected to follow a similar pattern.
For users who prefer a physical SIM card, there are still options that may exist through international models or carrier specific versions. So, here’s everything you need to know about the iPhone 16 SIM card slot.
The iPhone 16 SIM card slot setup varies depending on the region, continuing Apple’s shift toward eSIM technology. In the US market, Apple has adopted an eSIM-only approach, which means the iPhone 16 will continue the trend and won’t have a slot for a physical SIM card.
However, in other regions such as Europe, Asia, and parts of South America, iPhone 16 models still come with a dual SIM setup, offering one nano-SIM card slot alongside eSIM capabilities.
As a result, users can toggle between the data plan from their carrier’s physical SIM card and a different carrier using an eSIM installed on the same device.
Apple started introducing eSIM functionality in iPhones from the XS and XR models. The feature has since become a standard across the latest iPhone releases. Below is a complete list of eSIM-compatible iPhone models:
Any of these phones can use an eSIM, but models outside the US also have a physical SIM card slot. It’s worth checking whether your device offers dual SIM or dual-eSIM functionality.
The iPhone 16 SIM options vary depending on the region, with Apple offering different configurations to accommodate local carrier networks. While the US models are eSIM-only, other regions still include nano-SIM slots alongside eSIM support.
| Region | SIM configuration |
| United States | Dual eSIM (no physical SIM slot) |
| Canada | Dual eSIM or nano-SIM + eSIM |
| Europe | Dual eSIM or nano-SIM + eSIM |
| United Kingdom | Dual eSIM or nano-SIM + eSIM |
| China | Dual nano-SIM (no eSIM support) |
| Hong Kong | Dual nano-SIM (no eSIM support) |
| Japan | Dual eSIM or nano-SIM + eSIM |
| Australia | Dual eSIM or nano-SIM + eSIM |
| India | Dual eSIM or nano-SIM + eSIM |
| Middle East | Nano-SIM + eSIM (some carriers may restrict eSIM use) |
| Latin America | Dual eSIM or nano-SIM + eSIM (varies by carrier) |
If you want to use an eSIM and a SIM together, dual SIM setup ensures that you can use different carriers for data and calls. This is great for traveling, but also for separating work and personal phone lines.
It might seem like a disadvantage, then, that US iPhones don’t have a SIM card slot. However, the dual-eSIM setup means that you can install multiple eSIM profiles on the same device and use them in the same way.
If you want to buy the iPhone 16, you can do so anywhere in the world that Apple operates. However, keep in mind that the SIM configuration varies depending on where you buy it.
In the United States, Apple has fully transitioned to eSIM-only iPhones. So, if you purchase an iPhone 16 from Apple or other authorized retailers, you will not receive a physical SIM card slot. This means that, if you have a physical SIM card right now, you’ll need to purchase a new line to continue using your calls and data with an eSIM, rather than just switching your SIM to a new phone.
This shift to eSIM allows for easier activation, better security, and the ability to use multiple carriers on the same device. However, it can be a drawback for users who frequently swap SIM cards or prefer the flexibility of physical SIMs.
If you’re buying the iPhone 16 outside of the US, you have more SIM options. Depending on the region, you can find models with dual nano-SIM, nano-SIM + eSIM, or dual eSIM.
However, before purchasing an iPhone 16 from a different country, make sure its fully compatible with your local network. iPhones are designed to support specific cellular frequency bands, and buying a model from a different region could result in network issues, reduced coverage, or missing 5G support.
If you frequently travel or plan to use your device internationally, you should also check band compatibility with your local carrier.
Yes, you can purchase an iPhone 16 from another region and use it in the US with a SIM card, but there are some important factors to consider.
First, the iPhone must be unlocked to work with US carriers. Many phones sold outside the US may be carrier-locked or SIM-locked, meaning they only work with specific networks in the country of purchase. To use the device in the US, you’ll need to make sure it is unlocked or request an unlock from the original carrier. That way, you can insert a new SIM.
Additionally, network compatibility is crucial. Some international iPhone models may not support all US carrier bands, which could result in weaker signal strength or missing 5G support. Before purchasing, check the frequency bands of the iPhone model to ensure it will work with your preferred US carrier.
The iPhone 16 supports both physical SIM and eSIM, but your options depend on the region where you purchase the device. While eSIM technology is the future, some users may still prefer the traditional physical SIM card for various reasons.
| SIM Type | Advantages | Disadvantages |
| Physical SIM | Easy to switch between devices by swapping the SIM cardCompatible with most carriers worldwideCan use a SIM card from a local provider when traveling | Requires a physical SIM slot (not available in the US)Risk of damage or lossInconvenient if switching networks often |
| eSIM | No need for a physical SIM cardSupports multiple numbers and carriers on the same deviceMore secure (can’t be removed if the phone is lost or stolen)Easier activation, often without visiting a carrier store | Not all carriers support eSIMCan be more difficult to transfer to a new deviceSome users prefer a physical SIM for flexibility |
Apple has already taken a major step toward fully adopting eSIM technology by removing the physical SIM tray from iPhones sold in the US. After the iPhone 14, Apple signaled its commitment to future-proofing their devices, but only in the US. Whether this will happen globally remains uncertain.
While Apple is pushing for an eSIM-only future, the transition depends on carrier support and regional market demands. Some countries still lack widespread eSIM adoption, making it unlikely that Apple will remove the SIM tray worldwide in the immediate future. In regions where eSIM infrastructure is not well developed, Apple will likely continue offering iPhones with physical SIM slots alongside eSIM compatibility.
That said, as more carriers worldwide adopt eSIM technology, it's highly possible that future iPhones will become fully eSIM devices everywhere. This would allow for simpler device designs, better security, and easier carrier switching, aligning with Apple’s trend toward minimalistic hardware and digital-first solutions.
But don’t expect this to happen soon; it’s likely going to be a slow transition over the next several years.
The iPhone 16 Pro follows Apple’s recent trend of eSIM-only models in the United States, meaning it does not have a physical SIM card slot. However, in some international markets, Apple still offers models with dual SIM slots or a combination of physical SIM and eSIM.
Apple is gradually moving toward a fully eSIM-based ecosystem, starting with eSIM-only iPhones in the US. While physical SIM trays are still available in other countries, it’s likely that future iPhones will eventually eliminate SIM card slots globally as eSIM adoption increases. However, this is likely to be a slow transition.
Yes, if your iPhone 16 only supports eSIM, switching to an eSIM is necessary. eSIM offers seamless carrier switching, better security, and no need for a physical SIM card. But before switching, make sure your carrier supports eSIM and offers compatible data plans. If you’re a frequent traveler, an international eSIM provider can help you stay connected without expensive roaming fees.
