📱 Essential for K-Pass Users! Don’t Forget to Re-register After SIM Change

Special considerations exclusively for T-money and iZel mobile card users (+ tips for re-registration)

🔍 Why is re-registration necessary for T-money and iZel?

There’s a trend of changing SKT SIM cards these days. I received my new SIM yesterday and happily switched it… but to my horror, K-Pass payments declined! 😱 I found out that T-money and iZel mobile cards use the unique number of the SIM chip as an identifier. So when the SIM is changed, it’s like getting a completely new card!

A friend of mine didn’t know this and went over a month without using K-Pass, only to find out later. 😢 (That’s like throwing away 50,000 won every month…) Meanwhile, I was envious that KakaoPay or NaverPay don’t require re-registration.

📝 Essential procedures for K-Pass re-registration after SIM change

Let me share the re-registration process that I went through! It’s surprisingly simple! ✨

1. Access the K-Pass website or app
2. Click on My Info > Manage Payment Methods
3. Delete the previously registered T-money/iZel card
4. Re-register the card issued with the new SIM
5. Check for normal operation after 1-2 minutes!

In my case, I fixed it in just 3 minutes while in the restroom during lunch (although I was initially stressed when the app kept crashing…)

💳 Additional precautions for mobile pay users

If you’re using Samsung Pay or Apple Pay with your transit card, this isn’t the end! 🚨 When you change your SIM, the transit card registered on your mobile pay also resets!

Let me share my experience. I completed the K-Pass re-registration, but after not re-registering on Samsung Pay, I got caught off guard when the subway showed a “Insufficient Balance” message! 😅 So, make sure to check these two things:

1. K-Pass re-registration complete
2. Mobile Pay re-registration complete

✅ Services that do not require re-registration?

I thought everyone had to re-register, but that’s not the case! The following services can continue to function even after changing SIM:

• KakaoPay mobile card
• NaverPay transit card
• iM One Pass
• Rail Plus

It turns out that these services use the app’s unique number instead of the SIM number. I had no idea the technological difference was this significant! (I felt like an expert, haha)

💡 Re-registration tip that takes only 1 minute

Let me share some pro tips based on my failed experience!

• Wait 10 minutes after inserting the new SIM before re-registering → the system needs time to recognize it!
• Proceed in a Wi-Fi environment → unstable data can lead to registration failure
• Check that the card issuer’s app is updated to the latest version → errors might occur on outdated versions

Initially, I tried to re-register right after inserting the new SIM and failed three times… It was quite a test of patience! 😭

❓ K-Pass re-registration Q&A

Q. How soon should I re-register after changing SIM?

A. As soon as possible! Try to handle it on the same day to avoid situations where K-Pass doesn’t work on your commute the following day. (Advice from an experienced person…)

Q. What happens to my existing balance after re-registration?

A. Don’t worry! Balances are automatically transferred. However, it may take 1-2 hours, so proceed with some leeway.

Q. Is there a limit to the number of re-registrations?

A. As far as I know, you can do it up to 5 times a month. For more than that, you need to contact customer service.

Q. Does the card number keep changing if I change the SIM multiple times?

A. Yes! T-money and iZel receive a new card number each time the SIM is changed. Isn’t that interesting?

📖 A story of not being able to use K-Pass after changing SIM (review)

Let me share a true story from last week. I received a new SIM and happily changed it, but… the next day on my commute, K-Pass wouldn’t work! I hurriedly paid with a regular transit card but was upset about missing out on the 50% discount. 😢

Upon returning home, I learned that re-registration was necessary. I wrote this article hoping you won’t make the same mistake I did! (Honestly, while writing this, I double-checked myself, haha)

Don’t forget to re-register your K-Pass after a SIM change! I hope you have a comfortable bus ride on your way to work tonight! 🚌💨
