Does iPhone 16 Support eSIM?

Yes -- all four iPhone 16 models support eSIM: the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max. Apple has included eSIM as standard across the entire iPhone lineup since the iPhone XS and XR in 2018, and the iPhone 16 series is fully compatible with all major travel eSIM providers including LimitFlex.

iPhone 16 eSIM specifications

• All four iPhone 16 models (16, 16 Plus, 16 Pro, 16 Pro Max) support eSIM
• UK and international models: physical nano-SIM tray plus eSIM (dual SIM)
• USA models: eSIM-only (no physical SIM tray) since iPhone 14
• Multiple eSIM profiles: Up to 8 eSIM profiles can be stored; two can be active simultaneously on supported models
• 5G: All iPhone 16 models support 5G on both physical SIM and eSIM

How to install eSIM on iPhone 16

• Open Settings on your iPhone 16
• Tap Cellular (or Mobile Data in the UK)
• Tap Add eSIM
• Tap Use QR Code
• Point the camera at your LimitFlex QR code (or enter the details manually)
• Tap Continue and then Add Cellular Plan to confirm
• Label the eSIM (e.g. 'Holiday Data') and set it up as your data line

Setting up dual SIM on iPhone 16 for travel

In Settings → Cellular, you can set which SIM handles calls, texts, and data independently. For travel, set your UK physical SIM as 'Default Voice Line' (so your UK number stays active for incoming calls) and set your LimitFlex eSIM as 'Cellular Data' to use local data rates. Turn on Data Roaming for the travel eSIM.

Does iPhone 16 support two eSIMs simultaneously?

Yes. iPhone 16 models can have two eSIMs active simultaneously (Dual eSIM mode). In practice, most travellers use one physical SIM plus one eSIM -- the standard dual SIM configuration. Dual eSIM allows two eSIM profiles to be active at the same time without a physical SIM at all.

iPhone 16 eSIM for travel: what to expect

The iPhone 16's eSIM experience is seamless. Once your LimitFlex eSIM is installed, it will connect automatically to local networks as you travel. In countries with 5G networks, the iPhone 16 will connect to 5G automatically for faster speeds. Coverage and speed depend on the destination network rather than the phone.
