The latest US version iPhone 17 is eSIM only. How to use it when returning to China?

On September 17, 2025, Apple's latest iPhone 17 officially launched, continuing the US version's pure eSIM design—featuring a smooth body with no physical SIM card slot.

According to multiple tech media reports, Apple is accelerating its eSIM-only strategy. Since the iPhone 14, US models have eliminated the physical SIM slot; with the iPhone 17 series, this design will extend to more countries and regions, making "slotless iPhones" a potential global trend in the future.

While this aims for a cleaner communication experience, for those frequently traveling between China and the US, bringing a US version iPhone 17 back to China means the eSIM-only design instantly turns the phone into a "brick," leaving you disconnected the moment you step off the plane.

Why Does the US Version iPhone 17 Lose Connection in China?

● Carrier Incompatibility: China's three major carriers do not yet fully support eSIM functionality, making it impossible to activate a local Chinese number on the iPhone 17.

● Physical Limitation: Phones without SIM slots cannot use physical SIM cards, rendering the traditional communication solution for returning home ineffective.

● Service Disruption: Without a local Chinese number, you cannot receive bank/payment verification codes, use WeChat Pay or Alipay, or book rides and meals.

● The Burden of a Backup Phone: The conventional solutions of "carrying a backup phone" or "buying an Android phone upon arrival" are not only troublesome but also offer a poor experience.

So the question is, how can you use the iPhone 17 in China? Don't worry, there are now smart and seamless solutions that completely bypass the eSIM-only limitation.

Solution 1: iTalkBB Prime App - Dual US & China Numbers, Perfectly Bypassing Physical Limits

The iTalkBB Prime App lets your phone have both US and Chinese numbers simultaneously—no SIM card needed, no slot required—making it perfectly compatible with the US version iPhone 17. You can use it daily in the US and switch seamlessly when back in China, no longer worrying about your phone becoming useless.

Solution 2: iTalkBB China Connect eSIM Data Plan—Say Goodbye to Costly Roaming Fees

Besides communication, internet access in China is equally essential. Many overseas Chinese prefer their US carrier's international roaming when visiting home, but the high bills are often shocking (Reference: 《$120 Roaming Bill in China?

If you're only returning for a short visit, vacation, or business trip, the iTalkBB China Connect eSIM data plan is an ideal supplement. Designed specifically for eSIM-only phones, get connected immediately upon landing, and it's more affordable than international roaming.

As the comparison shows, with the iPhone 17's eSIM-only design becoming a trend, traditional Chinese SIM card solutions are becoming obsolete. Using the iTalkBB Prime App for communication and iTalkBB China Connect for internet is the optimal combination for US version iPhone 17 users returning to China!
