I was 9 PM and off to the UK the next day.
Suitcase packed, passport at the ready but then the realization dawned.
No SIM card. No international plan. No roaming agreement.
I had two choices:
- Purchase a local SIM at Heathrow
- Use public Wi-Fi and hope
That’s when I recalled hearing about something called an eSIM.

The 5-Minute Fix: Finding eSIM
I searched Google for “Best UK eSIM for travelers” and discovered WorldSIM’s eSIM page.
I was dubious at first. But the advantages were obvious:
- No SIM card required
- Instant activation
- Works in 190+ nations
By 9:10 PM, I had my eSIM card activated with a data plan installed.
Touchdown in the UK: Easy Going
The moment the plane touched down, I switched out of airplane mode.
Boom instant connectivity.
No lines, no searching for kiosks, no expensive airport SIMs.
With my UK eSIM, I had:
- Google Maps to locate my hotel
- WhatsApp for check-in notifications
- Uber reserved in mere seconds
Next Stop: Hong Kong
A week later, I needed to travel to Hong Kong for a conference.
Normally, I’d worry again about connectivity.
But this time, I just opened https://www.worldsim.com/data-esim, chose a Hong Kong data pack, and clicked “Buy Now”, scanned QR & activated.
Within a few minutes, I had arrived at high-speed internet.

FAQs About eSIMs in the UK
What’s the difference between an eSIM and a physical SIM in the UK?
A physical SIM is a removable plastic card. An eSIM is built into your phone and works digitally. You don’t need to insert anything. Just scan a code and connect. It’s quicker, cleaner, and easier to manage.
Can I use my number with an eSIM?
Yes. Your original number stays active even while using an eSIM for data. That means you can still receive calls and texts on your usual number while using your eSIM to get online.
Do I need Wi-Fi to activate an eSIM?
Yes, you’ll need a basic Wi-Fi connection for setup. Once your QR code is scanned and your plan is active, you’re ready to go. No Wi-Fi needed after that unless you want to switch plans.
What if I delete my eSIM accidentally?
If that happens, just reach out to support. They can resend your QR code so you can reinstall it. It’s a quick fix, but try not to delete it unless you’re sure you’re done with it.
Can I use an eSIM for WhatsApp, FaceTime or iMessage?
Definitely. WhatsApp stays connected to your original number, and iMessage and FaceTime work just like normal. You won’t lose access to any of your go-to apps.
