Your UK eSIM – Quick & Easy Setup

Written by Ciara Bellisio

Installing Your UK eSIM

Your UK eSIM is your main CyberTel connection — it gives you your UK number, unlimited calls and texts, and access to EE's 5G network. You'll receive your eSIM instantly by email once your order is complete.

All you need is your QR code and a few minutes to set it up.

Before You Start

Make sure you have:

  • ✅ An unlocked eSIM-compatible phone

  • ✅ A WiFi connection — needed to download the eSIM

  • ✅ Your CyberTel eSIM QR code — emailed to you after checkout

  • ✅ Your device passcode for installation confirmation

Can't find your QR code email? Contact our team and we'll resend it instantly.

iPhone Setup (iOS 16 or later)

  1. Open your CyberTel eSIM email

  2. On your iPhone go to Settings → Mobile Data → Add eSIM

  3. Choose Use QR Code

  4. Scan the QR code from your CyberTel email

  5. Tap Add Mobile Plan when prompted

  6. Label your eSIM — we recommend "CyberTel UK"

  7. Choose your default SIM for calls and data — you can change this later

💬 Once added, your UK number will appear under Settings → Phone → My Number.

Android Setup (Samsung, Google & others)

  1. Open Settings → Network & Internet → SIMs

  2. Tap Add eSIM or Download a SIM instead

  3. Choose Use QR Code

  4. Scan your QR code from your CyberTel email

  5. Confirm and follow the on-screen prompts

💡 Your CyberTel eSIM will activate automatically within a few minutes.

Activation Confirmation

Once installed:

  • Your CyberTel UK number will appear in your SIM settings

  • You'll receive a confirmation SMS from CyberTel

  • You can now make and receive calls, send texts, and use your UK data

If your number doesn't show immediately, don't worry — it can take a short while to update in your phone settings. You can still make and receive calls as normal in the meantime.

If You Ported Your Number

If you transferred your number from another provider via PAC code, the transfer will usually complete within 24 hours Monday to Friday.

After the transfer:

  1. Go to Settings → Phone → My Number (iPhone) or Settings → About Phone → SIM Info (Android)

  2. Check your CyberTel number appears correctly

  3. If your old number still shows, restart your phone

  4. On iPhone go to Settings → Messages → Send & Receive and make sure your new number is selected for iMessage and FaceTime

💬 It can sometimes take up to 7 days for Apple to update iMessage and FaceTime automatically. Contact us and we can refresh it sooner.

Removing an Old SIM

If you've switched from a physical SIM:

  1. Go to Settings → Mobile Data

  2. Tap your old SIM and choose Remove Mobile Plan

  3. Restart your phone

  4. Confirm your CyberTel number shows correctly in settings

This ensures your device uses your CyberTel UK eSIM for all calls, texts, and iMessage and FaceTime services.

FAQs

Q: What if my QR code doesn't scan?
Make sure your screen brightness is high, or try printing the QR code. If it still fails, contact us and we'll reissue one instantly.

Q: Can I install the eSIM on more than one phone?
No — eSIMs are one-time-use per device. Contact our team if you need to move it to a new phone and we'll reissue your QR code.

Q: Do I need to keep the QR code?
Keep it safe until activation completes. You can always request a new one from our team if needed.

Q: Will my CyberTel eSIM work abroad?
Yes — depending on your plan, you'll have roaming access across Zones 1 & 2 (Standard plans), Zones 1–3 (Explorer), or Zones A–D (Global Roaming plans).
