The iPhone 16 series can store eight or more eSIMs, but can only have two active eSIMs simultaneously.
No, it depends on where you buy your iPhone 16 device. The iPhone 16 is NOT exclusively eSIM-only for all markets worldwide. Apple has adopted a region-specific approach to SIM technology in the iPhone 16 series.
Here is a detailed explanation of the SIM configurations for the iPhone 16 across different regions:
In the United States, all iPhone 16 models are indeed eSIM-only, with no slot for a physical SIM Card. iPhone users in the U.S need to use eSIM technology to connect to mobile networks. These devices can support multiple eSIMs, allowing users to switch between carriers digitally.
In most countries, including Canada, Mexico, and European countries, etc. iPhone 16 models come with both options: a slot for a physical SIM card and also support eSIM.
Users can utilize dual SIM functionality with one eSIM and one physical SIM, or two eSIMs.
The iPhone 16 sold in mainland China, Hong Kong, and Macau come with two slots for physical SIM cards and do not support eSIM at all.
We summarize the differences in iPhone 16 SIM configuration in the table below:
| Region | eSIM support | Physical SIM slot | Dual SIM Capability |
| United States | Yes | 0 | Yes (dual eSIM) |
| Mainland China, Hong Kong, Macau | No | 2 | Yes (Dual physical) |
| Rest of the world | Yes | 1 | Yes (both) |
