Skip home-carrier data roaming, SIM swaps, contracts, airport kiosk queues and ID checks. You need only an eSIM-capable, carrier-unlocked phone, with no physical SIM to collect before you start exploring.
Keep your existing number while the eSIM handles data only. Your own SIM stays in your phone for calls, SMS and bank codes, while WhatsApp keeps your existing number.
Choose a short plan for a Seoul city break exploring palaces and markets. Longer plans suit travellers linking Seoul with Gyeongju, Busan and a separate flight to Jeju.
Get your data profile ready before departure by installing it at home. On arrival, you can connect without hunting for airport Wi-Fi, including before passport control where a connection is available.
What it is not: a phone number. For a local number to receive sign-up codes or bookings, add a virtual number next to the data plan.
How it works
Land in South Korea already online
Set it up on Wi-Fi the night before. The eSIM waits quietly until you arrive.
2
Pay and scan the QR code
Pay from your balance and get the QR code at once.
3
Turn it on when you land
Turn on data roaming and it finds a network itself.

What customers say
Best virtual number website
Using this site from more than 1 month and everything works perfect till now.. no problem faced.. UI is simple and easy to understand, buying number is fast.. numbers are always fresh and otp comes instantly no waiting time.. I really suggest them best site in 2026
Worked as intended
Well, it worked as intended. It was very easy to use the service, so I can only recommend it. Wish there were help desk to check some questions but regardless it was a satisfactory purchase.
Excellent service. So happy I found it
Excellent service. Works when it works and replaced when it doesnt. Fair pricing and good perks as well.
It definitely works
It definitely works, but it can be confusing if you are not aware of what some of the services do to prevent having multiple numbers. WhatsApp will try to prevent you from making a new number on the same phone. Just have to use another phone to create the account and then you can sign in properly. I was confused why I kept going through so many numbers not working, but it was because I was using the same device that I recently had an account on. I deleted my previous account, but WhatsApp saves your device info for 30 days.
Much more reliable
SMS a little more expensive than other pages, but they are much more reliable, and work.
My experience has been great
My experience has been great because 1001sms has made my job so effortless and a 10 man task feel like a job for just 1.
Great service
Great service, absolute amazin for 3rd Countries who cant use amaing services without phone numbers
I have used number from this site and it's good
I have used number from this site and it worked perfectly. 1001sms is a good choice when it comes to getting number from any country and any service
Good to know
