Need a second phone number without carrying two phones? A UK eSIM from BuyUKeSim works as a dual SIM setup: keep your existing SIM card for personal use, and add a UK +44 number as a second line for verifications, business, or privacy.
How dual SIM works with UK eSIM
Modern phones support two SIMs simultaneously: one physical SIM + one eSIM (or two eSIMs). When you install a BuyUKeSim UK eSIM, your phone gets a second number. You choose which SIM to use for calls, SMS, and data — or set the UK number for SMS only.
Setup on iPhone
- Your main SIM stays in the physical slot (or as primary eSIM).
- Scan the BuyUKeSim QR code to add the UK eSIM.
- Label it "UK +44" in Settings → Cellular.
- Set it as the line for specific contacts or for SMS verification.
Setup on Android
- Keep your primary SIM in the SIM tray.
- Add the UK eSIM via Settings → Network → Add eSIM.
- Toggle which SIM handles calls, SMS, and data.
Use cases for a UK second number
- App verification — WhatsApp, Telegram, Instagram, Revolut/Wise
- Privacy — keep your real number private, give out +44 instead.
- Business — separate UK line for UK clients.
- Travel — receive UK SMS abroad without roaming on your main line.
