How to Activate UK eSIM on iPhone & Android – Step by Step

After you buy a UK eSIM from BuyUKeSim and receive the QR code, activation is simple. On iPhone: go to Settings > Cellular > Add Cellular Plan, then scan the QR code. Follow the prompts to label and set the line (e.g. as default for data or only for calls/SMS). On Android: go to Settings > Network & Internet > SIMs (or similar), tap Add eSIM or Scan QR, then scan the code. Once the eSIM is installed, your phone will have a second number – your UK +44 line. Use it for WhatsApp, banking, or any app that asks for a UK number.

Tips

Keep the QR code safe until the eSIM is installed; some providers allow only one scan. If your phone supports dual SIM, you can keep your primary SIM and use the UK eSIM for the +44 number. For "activate UK eSIM" or "install eSIM iPhone/Android", this is the general process; BuyUKeSim delivers the QR right after payment so you can activate immediately.
