為什麼外國版iPhone只有eSIM？香港與內地版會跟進嗎？

Why do iPhones in foreign markets only have eSIM? Will Hong Kong and mainland China versions follow suit?

In recent years, "eSIM iPhone" has become a hot product in the global mobile phone market. Many consumers have noticed that iPhones purchased in the US or certain overseas regions have removed the physical SIM card slot (nano SIM) and fully adopted eSIM. What is the reason behind this change? Will the Hong Kong and mainland China versions follow suit? This article provides an in-depth analysis.

Why did foreign iPhone versions switch to eSIM?

Since iPhone 14, the US version has fully adopted an "eSIM only" design, no longer providing a physical SIM card slot. This is mainly due to the following reasons:

1. Enhanced security and convenience

eSIM is an embedded chip and cannot be removed like a physical SIM, offering greater security if the phone is lost. At the same time, users can directly download data plans without needing to change cards.

2. Support for multiple numbers and travel needs

An iPhone can store multiple eSIMs and switch between them at any time, which is particularly convenient for frequent travelers.

3. Space saving inside the device

Removing the SIM card slot helps make the internal design of the phone more streamlined, for example, by providing more space for the battery or other hardware. This is also one of the important factors driven by Apple.

Why do Hong Kong and mainland China still retain physical SIMs?

Although eSIM technology is mature, the market situation in Hong Kong and mainland China is more unique:

1. Telecommunication provider support is not yet fully widespread

Currently, not all regional telecommunication providers fully support eSIM, especially in some Asian markets where physical SIMs are still mainstream.

2. Mainland China policy restrictions

iPhones in mainland China have long not supported eSIM functionality, mainly due to real-name registration and regulatory policies.

3. Hong Kong market still prefers dual physical SIMs

Hong Kong versions of iPhone mostly adopt a "dual physical SIM" design to meet the needs of business and cross-border users.

Will there be a complete switch to eSIM in the future?

Based on market trends, the answer is "possibly, but not very quickly":

  • Apple has gradually expanded eSIM-only design to more countries.
  • New devices (such as the iPhone 17 series) are rumored to further remove the SIM card slot.
  • However, the Chinese market is still limited by policies and infrastructure, making a complete shift unlikely in the short term.

In other words, global eSIM adoption is a trend, but regional differences still exist.

What are the advantages of eSIM for travelers?

For frequent travelers or data card users, eSIM offers clear benefits:

  • Instant activation, no card insertion required
  • 1worldsim.com supports data plans for countries worldwide
  • Can use local number + travel data card simultaneously

This is why "travel eSIM / international internet card recommendations" has become a highly searched keyword in recent years.

Conclusion: Choose eSIM or physical SIM?

If you are considering purchasing a foreign version of the iPhone, please note:

  • US version: eSIM only
  • UK / European version: eSIM + physical SIM
  • Hong Kong / Chinese version: Primarily physical SIM

For users who prioritize convenience and travel frequently, eSIM is undoubtedly the future mainstream choice; however, if you still rely on local physical cards or have regional restrictions, you need to choose your phone model carefully.
