Korean 010 Number for Tourists: Waitlists, Verification and 012 Numbers (2026)
The tablet at the restaurant door wants a 010 number. What a tourist voice SIM really unlocks in Korea, why 012 numbers get rejected, and when a data-only eSIM is all you need.
Quick answer: Tourists can get a Korean 010 number only from a carrier SIM or eSIM that includes voice, and it works after you verify your passport in Korea; it passes SMS checks for restaurant and taxi apps but not identity verification for banking or government services. A data-only eSIM, including Fizen's, gives no Korean number at all, so it suits travellers who can live without waitlist texts.
Key takeaways
- 010 is the normal Korean mobile prefix. Waitlists and loyalty sign-ups expect it, and 012 numbers often fail those forms.
- Voice and SMS start only after passport verification. SKT runs it online from 8 AM to 10 PM after immigration, or at an airport roaming centre.
- A tourist 010 number is not a Korean identity. LG U+ says its voice SIM passes restaurant and taxi app SMS checks, not banking or government identity checks.
- Data-only means no number. Fine for maps, Kakao T on your home number and messaging; not for waitlist texts.
Seongsu, Saturday, 12:40. The bakery has a tablet by the door instead of a queue, and it wants your phone number for the text that says your table is ready. Your home number will not go in, and the Korean eSIM you bought online shows a number starting 012, which the form refuses too. Here is what a tourist can and cannot get in Korea in 2026, from carrier pages and the travellers who asked first.
Why do Korean waitlists and apps ask for a 010 number?
In Korea, 010 is the standard mobile prefix, and many sign-up forms only accept it. A traveller on the South Korea forum listed the two places it bites: restaurant waitlists that text you when your table is ready, and loyalty or point programmes you cannot join without a Korean number.
The 012 prefix is a different thing. A Korean poster explained that 012 numbers are issued for second devices such as smartwatches, LTE routers and cars, so some forms simply refuse them. Another traveller who used a KT eSIM noted that it came with a 012 number when delivered by email, and with a standard 010 number when collected at the airport (KT's terms may have changed since, so check before you order).
How does a tourist get a working 010 number?
Buy a carrier SIM or eSIM that includes voice, then verify your passport in Korea. SKT's rules, read on 26 October 2026:
- After immigration only. Passport verification opens once you have cleared Korean immigration.
- Online from 8 AM to 10 PM, through the QR code in the voucher; outside those hours, at the airport roaming centre.
- Incoming calls and texts work after verification; outgoing ones need credit added.
- Foreign passports and stays of up to 90 days only.
LG U+ sells a data-and-voice SIM with a 010 number, with voice enabled after passport verification at the airport counter. Its own notice is the honest limit: SMS verification for restaurant and taxi reservation apps works, identity verification for banking or government services does not.
What people who have done it say
- Pick the delivery that gives 010. One traveller happily used an email-delivered eSIM with a 012 number and said to collect at the airport only if you need a standard 010.
- Verify at the airport if you land late. The online check closes at 10 PM, so a night arrival means the roaming centre or waiting until morning.
- A number for texts is not an identity. One poster wanted a permanent 010 for waitlists and point cards; the only reply pointed to an eSIM with a Korean number that cannot pass identity verification.
- Many travellers never need it. Posters on data-only plans used messaging apps and their home number for app sign-ups.
When is a data-only eSIM enough in Korea?
When your plan is maps, Naver or Kakao Map, messaging, translation and taxi apps registered with your home number. A Fizen travel eSIM is data-only: it gives no Korean number, no 010 and no 012, and it will not get you onto a waitlist that insists on a Korean text. Keep your home SIM on for bank codes and app sign-ups.
In the Fizen catalogue on 26 October 2026, the Korea country plans run on LG U+ 4G and 5G. Fixed-data plans slow to 128 kbps once used up; the unlimited plan states no speed cap. A verified Fizen-side fault gets a free 1-for-1 replacement for the trip, handled by a real person in chat.
Which setup should you pick?
| Your trip | What to get |
|---|---|
| Restaurants with waitlists, pop-up stores, loyalty sign-ups | A carrier voice SIM or eSIM with a 010 number, verified after landing |
| Maps, messaging, taxis on your home number | A data-only eSIM installed at home |
| Both, on an eSIM phone | A voice line for the 010 number and a data eSIM alongside, if your phone holds both |
| Korean banking or government apps | Neither works; these need resident identity |
Changed plans? An unused, not-yet-installed eSIM can usually be taken back; eligibility depends on the plan, check Package details or ask chat.
