Korean Phone Number Guide 2026: Tourist SIMs & Face ID Rules

So you want to order fried chicken to the Han River or queue for that viral bagel spot in Gangnam? You are going to need a local "010" number.

The question of "Can I get a Korean phone number on a tourist SIM?" is the million-won question for travelers in 2026. The short answer is YES, but there are some strings attached that you really need to understand before you land. While you can easily buy a prepaid SIM card (or eSIM) that comes with a local 010 number, doing so without an Alien Registration Card (ARC) means you are playing "Korea on Hard Mode" regarding identity verification.

This guide covers exactly how to get a number without an ARC, how to navigate the new 2026 facial recognition rules like a pro, and why you desperately need a number to avoid being a digital ghost during your trip.

The Background Story: Why It's So Strict

To understand why getting a SIM card in Korea feels like applying for a security clearance, we have to look at the history. Back in the early 2010s, Korea had a massive problem with "Voice Phishing" and burner phones used for crimes. The government cracked down hard, introducing the "Real Name Verification System," making it illegal to own a SIM card that isn't tied to a verified identity.

Fast forward to 2026, and things have gotten even stricter. As of December 2025, the Ministry of Science and ICT piloted a new rule that became mandatory in March 2026: Facial Recognition.

Because criminals were finding ways to activate SIMs with stolen passport scans, the government now requires a live facial scan when you activate a new SIM card. Whether you are at Incheon Airport or a 7-Eleven in Hongdae, the activation process now involves a tablet scanning your face to match it against your passport photo in real-time. It feels a bit sci-fi, but it’s the new reality. This security paranoia is also why your tourist SIM dies the moment your visa expires—everything is tightly linked to immigration data.

Breaking Down Your Options

Now that you know the rules, let's look at how to actually buy one. You essentially have three paths, and the price difference is massive.

Option A: The "Big 3" Roaming Desks (SKT, KT, LG U+)

If money is no object and you just want convenience, this is it. These are the official carrier desks right in the arrival hall.

• The Vibe: Reliable, fast, English-speaking staff.
• The Cost: Expensive. Expect to pay around ₩71,500 ($53) for a 30-day unlimited data plan with a number.
• Best For: Business travelers or short-term tourists who don't care about saving $20.

Option B: The "Budget Kings" (Chingu Mobile / Woori Mobile)

These are Mobile Virtual Network Operators (MVNOs). They use the exact same towers (usually KT or SKT networks) but charge way less.

• The Vibe: Scrappy but efficient. You usually pre-order these online (via Trazy/Creatrip) and pick them up at a specific counter or bookstore at the airport.
• The Cost: Much better. A 30-day plan here is often around ₩35,000–₩40,000 ($26–$30). That's nearly half price.
• Best For: Students, budget travelers, or anyone staying longer than a week.

Option C: Data-Only eSIMs (Airalo, Nomad, etc.)

These are super convenient because you can install them while still in your home country.

• The Catch: Most of these are DATA ONLY. No phone number.
• The Problem: You save money, but then you arrive at "London Bagel Museum," realize you need a Korean number to join the digital queue, and cry silent tears of regret. Only choose this if you have a friend with a Korean number who can queue for you.

Pros and Cons of MVNOs (Recommended Option)

We generally recommend the MVNO route (Option B) for most travelers. Here is why, along with the honest downsides.

The Complete How-To Guide

Let’s walk through the exact process for 2026, assuming you want the smart option (Option B: MVNO with a number).

The Stuff Nobody Tells You

Even with your shiny new 010 number, you are a second-class digital citizen. You cannot order delivery on the main "Yogiyo" or "Baemin" apps easily because they require "Identity Verification" (linking your number to a Resident ID). This is a common pain point for digital nomads. If you are struggling with banking or verification, check out our guide on NH vs Hana Bank 2026 for long-term solutions.

The Restaurant Queue Hack

Many trendy spots use a tablet at the door where you input your phone number to queue. You input your new 010 tourist number, but you must watch your phone like a hawk. Some systems send a KakaoTalk message; others send a regular SMS. If you miss the notification, they skip you instantly.

The Recycling of Numbers

Korean phone numbers are recycled aggressively. You might get a SIM and immediately start receiving texts for "Mr. Kim's dental appointment." It's annoying but normal. Just ignore them. Also, once your SIM expires (e.g., after 30 days), if you don't top up within 3-7 days, that number is gone.

Warnings and Tips

Download "CatchTable Global" BEFORE you arrive. While the local version of CatchTable (restaurant reservation app) requires a verified number, the Global version allows you to book with an email. However, for "Remote Queuing" (waiting in line virtually), you often need the local number. Having the app ready saves stress.

No Korean Phone/ARC? Here's What To Do If you are stuck without a number or verification:

1. Taxi: Use KakaoT but swipe to "General Taxi" (Blue/Smart call won't work) and select "Pay to Driver" as the payment method. You don't need a card registered in the app.
2. Food: Use Shuttle Delivery (fully English, takes foreign cards). Or, use the Baemin app, select "Meet and Pay Card/Cash" if available (becoming rarer), or use a concierge service like Help Me Emo.

Conclusion

Don't overthink it, but don't cheap out either. Your action plan is simple: Do not settle for a data-only eSIM unless you are on a strict budget and hate convenience. Pre-order a SIM with a 010 number from a provider like Chingu or Woori Mobile via Trazy or Creatrip before you fly. It’s the best balance of price and utility.

Prepare for the face scan—it’s the new normal in 2026. Having that 010 number is the difference between feeling like a helpless tourist and feeling like a savvy traveler who can actually participate in the local culture. Trust me, when you're 45 minutes deep in a waiting list for black pork BBQ and your phone actually buzzes to let you in, you'll be glad you spent the extra few dollars.
