eSIM for iPhone: UK Setup Guide, Compatible Models & Activation (2026)

Most iPhones from the iPhone XR and newer support eSIM, including all iPhone 11, 12, 13, 14, 15, and 16 series models.

To confirm eSIM support, go to Settings → Mobile Service (or Cellular) — if you see an "Add eSIM" option, your device is compatible.

To activate, tap Add eSIM, then scan your provider's QR code or log into your provider's app. The process takes under five minutes and requires a Wi-Fi connection.

eSIM availability may vary depending on region, carrier, and iPhone model.

In short:

• iPhone XR and newer → eSIM supported

• Check in Settings → Mobile Service (or Cellular) → Add eSIM

• Activate via QR code or provider app

An eSIM (embedded SIM) is a digital SIM card built directly into your iPhone. Unlike a physical nano-SIM that you insert into a tray, an eSIM is activated entirely through software — no card, no store visit required.

On most iPhones, eSIM works alongside a physical SIM slot, giving you true dual SIM capability — two active numbers or plans on a single device.

For a full breakdown of how the technology works, see our guide on what is eSIM.

Here's a clean breakdown of every iPhone that supports eSIM, grouped by generation.

According to Apple, eSIM support may vary depending on region, carrier, and iPhone model.

Latest iPhones with eSIM (2022–2026)

Mid-Range Supported Models (2018–2022)

Devices That Do NOT Support eSIM

⚠️ Important Notes:

• US iPhone 14 and newer — these models are eSIM-only. There is no physical SIM tray. They support dual eSIM (two eSIM profiles active at once).

• Mainland China models — iPhones sold in mainland China typically do not support eSIM due to regional regulations.

• Carrier-locked devices — if your iPhone is locked to a specific carrier, eSIM functionality may be restricted. Check via Settings → General → About → Carrier Lock.

Does the iPhone 11 Support eSIM?

Yes. The iPhone 11, 11 Pro, and 11 Pro Max all support eSIM. These models feature a dual SIM setup — one physical nano-SIM and one eSIM — allowing two active lines simultaneously.

Does the iPhone SE Support eSIM?

Yes — but only the 2nd generation (2020) and 3rd generation (2022) models. The original iPhone SE from 2016 does not support eSIM. If you have a newer SE, go to Settings → Cellular → Add eSIM to confirm availability on your carrier.

Does the iPhone 14 Have a Physical SIM Card Slot?

No — not in the United States. US models of the iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max are eSIM-only. The physical SIM tray has been removed entirely. International models sold outside the US retain a physical nano-SIM tray alongside eSIM support.

Does the iPhone 13 Support eSIM?

Yes. All iPhone 13 models — including the mini, Pro, and Pro Max — support eSIM alongside a physical SIM slot. US models can run dual eSIM; international models support one physical SIM and one eSIM.

Does the iPhone 12 mini Support eSIM?

Yes. The iPhone 12 mini supports eSIM, along with the full iPhone 12 lineup. It runs a physical nano-SIM and one eSIM simultaneously for dual SIM capability.

Activating an eSIM on iPhone is straightforward. Here are both methods clearly laid out.

For UK travellers, roaming charges can quickly add up when using your home network abroad, especially across Europe and international destinations. A travel eSIM offers a much more cost-effective alternative.

This is where iPhone eSIM delivers its greatest value. Instead of paying expensive roaming fees or scrambling for a local SIM at the airport, a travel eSIM gives you instant connectivity before you even board.

Why a travel eSIM beats roaming every time:

• No roaming charges — home carrier roaming can cost £5–£15 per day. A travel eSIM gives you local data rates at a fraction of the cost.

• Works in 200+ countries — regional and global eSIM plans cover Europe, Asia, the Americas, and beyond with a single plan.

• Activate before you fly — set up your travel eSIM from home and land with data already running. No airport queues, no SIM kiosks.

• Keep your home number active — with dual SIM, your primary number stays live for calls and texts while your travel eSIM handles data.

• Instant activation — most travel eSIM plans go live within seconds of installation.

A travel eSIM is one of the easiest ways to stay connected abroad without changing your number or relying on expensive roaming plans.

How to switch between eSIM profiles: Go to Settings → Cellular, tap the plan you want to use, and toggle it on. Set your preferred line for Mobile Data, calls, and messages separately.

How to rename an eSIM: Go to Settings → Mobile Service (or Cellular) → [Your eSIM] → Cellular (or Mobile) Plan Label and assign a custom name like "Work" or "Europe Travel."

How to remove an eSIM: Go to Settings → Mobile Service (or Cellular)→ [Your eSIM] → Delete eSIM. Note: removing an eSIM may require your provider to reissue it before reinstalling.

Transferring eSIM to a new iPhone: Use eSIM Quick Transfer during iPhone setup — place your new iPhone near your old one and follow the Quick Start prompts. Alternatively, log into your provider account and reinstall directly.

Warning: Always remove your eSIM profiles before selling your iPhone to protect your personal data and plan access.
