Which Older iPhone Models Support eSIM?

Apple began integrating eSIM technology into its phones in 2018. This means not all iPhones can use this feature. If your phone model is older than 2018 (e.g., iPhone 8, iPhone 7, or earlier models), it will not support eSIM and can only use traditional physical nano-SIM cards.

List of iPhone Models Supporting eSIM:

  • 2018 Models: iPhone XR, iPhone XS, iPhone XS Max
  • 2019 Models: iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max
  • 2020 Models: iPhone SE (2nd generation), iPhone 12 series
  • 2021 and Beyond: iPhone 13 series, iPhone 14 series, iPhone 15 series, and subsequent models like iPhone 16, iPhone 17 fully support eSIM.

Special Note: Starting with the iPhone 13 series, Apple introduced "dual eSIM" functionality, allowing you to activate two eSIM plans simultaneously; older models (such as iPhone XS to iPhone 12) typically maintain a "one physical card + one eSIM" configuration.

Two Important Fact Checks Before Purchasing an eSIM

Even if your iPhone model is on the supported list, you still need to confirm the following two key points to ensure successful activation of travel data:

  1. Regional Restrictions (China, Hong Kong, Macau versions): iPhones sold in mainland China (except for individual models like iPhone Air) mostly do not support eSIM, offering only dual physical SIM card slots.

    As for iPhones sold in Hong Kong and Macau, besides iPhone XS, iPhone SE (2nd/3rd generation), and iPhone 12/13 mini which support eSIM, most larger screen models are physical dual-SIM versions. It is recommended to check the model code by going to "Settings" > "General" > "About".

  2. Carrier Lock: If your phone is a contract phone or a carrier-specific discounted phone, it might have a carrier lock. Please ensure your phone is unlocked (showing "No SIM restrictions"), otherwise you will not be able to install eSIM plans from other service providers.

How to Quickly Check if Your Phone Supports eSIM?

If you are unsure of your model, you can check it yourself with these simple steps:

  1. Go to "Settings" > "Mobile Data" (Cellular).
  2. Look for the option to "Add eSIM" or "Add Cellular Plan".
  3. Alternatively, dial *#06#. If an EID barcode appears on the screen, it means the device has eSIM hardware capabilities.

Advantages of Using eSIM on Older iPhones

Using an eSIM not only eliminates the hassle of changing physical cards and the worry of losing your original card, but for older iPhone users, it is also the best way to achieve "dual SIM dual standby." You can keep your original Hong Kong phone number to receive SMS messages while using the affordable travel data provided by the eSIM.
