Question 1

Will my eSIM work on the Seoul subway and the KTX trains?

Accepted Answer

Yes, superbly. Korea's networks cover the entire subway, including deep tunnels, and the KTX high-speed line, so you can navigate, stream and translate without interruption between stops.

Question 2

Do I need a Korean ID or T-money registration to use it?

Accepted Answer

No. There's no ID requirement and no local registration — you scan the QR code, enable the eSIM on arrival and you're online, while your T-money transit card is bought separately at any convenience store.

Question 3

What is an eSIM?

Accepted Answer

An eSIM is a digital SIM card built into your phone. No physical card needed — just scan a QR code from your email or My eSIMs section to activate your plan instantly.

Question 4

Is my phone eSIM compatible?

Accepted Answer

iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+ and most phones from 2018 onwards support eSIM. Go to Settings → About — if you see an EID number, you are compatible.

Question 5

Can I keep my regular number?

Accepted Answer

Yes — our plans are data only. Your regular SIM stays active for calls and SMS. You stay reachable on your usual number while your eSIM handles data abroad.

Question 6

How many eSIMs can I have?

Accepted Answer

Most phones store up to 5-10 eSIM profiles but only one can be active for data at a time. You can switch between them anytime in your phone settings.

Question 7

How do I install my eSIM?

Accepted Answer

After purchase, find your QR code in your confirmation email or in My eSIMs. Go to Settings → Mobile Data → Add eSIM → Scan QR code. You need WiFi for installation.

Question 8

When should I activate my eSIM?

Accepted Answer

Install it before you leave — it only needs WiFi. Switch it as your data line only when you arrive at your destination. Your plan starts automatically at first local network connection.

Question 9

Do I need to enable data roaming?

Accepted Answer

Yes — enable data roaming for your eSIM Agora line in Settings → Mobile Data → select your eSIM → Data Roaming on. Without this, your eSIM cannot connect to local networks abroad.

Question 10

What if my QR code does not work?

Accepted Answer

Make sure you are on WiFi. Each QR code works only once — if already scanned, go to My eSIMs to reinstall. Still not working? Contact us at support@esimagora.com and we will fix it quickly.

Question 11

When does my data plan start?

Accepted Answer

Your plan starts at your first network connection at destination — not at purchase. Install at home, travel freely, your days only count when you actually use it abroad.

Question 12

Is hotspot included?

Accepted Answer

Yes — all our plans include hotspot at no extra cost. Share your connection with your laptop or tablet directly from your phone settings.

Question 13

Can I use my eSIM in multiple countries?

Accepted Answer

Single country plans work in one country only. If you visit multiple destinations, check our regional plans — Europe covers 33 countries, Asia 20, Worldwide 118 and more.

Question 14

Can I top up my plan?

Accepted Answer

Yes — you can top up your plan at any time from My eSIMs. Important: top up before your plan expires, as top-ups cannot be applied to expired plans.

Question 15

What is an Unlimited plan?

Accepted Answer

You get a set amount of high-speed data each day (e.g. 1 GB/day). Once you've used that daily quota, you keep browsing at reduced speed (1 Mbps) — never cut off. Every day, your high speed starts fresh.

Question 16

What's the difference between Unlimited and fixed GB plans?

Accepted Answer

Fixed (e.g. 5 GB/30 days): one total amount of data to manage over the whole period, at full speed until it runs out. Unlimited: a daily quota that renews, so you're never completely out. Ideal if you'd rather not track your usage, or if you're staying a while.

Question 17

What happens after I use my daily high-speed data?

Accepted Answer

You switch to 1 Mbps (enough for WhatsApp, maps and browsing, but not HD streaming). It goes back to full speed the next day.

Question 18

When does my daily data reset?

Accepted Answer

About every 24 h after your first connection (it can vary by carrier — not necessarily at midnight).

Question 19

Can I extend my Unlimited plan?

Accepted Answer

Yes — via "Add days" while it's still active (not expired). It adds days, not extra daily data.

Question 20

Unlimited or fixed — which is better for me?

Accepted Answer

Unlimited if: long stay, unpredictable usage, you want peace of mind. Fixed if: short stay, light or precise usage, you want the best value.

Question 21

What payment methods do you accept?

Accepted Answer

We accept Visa, Mastercard, American Express and Google Pay. All payments are processed securely by Stripe.

Question 22

Is my payment secure?

Accepted Answer

Completely — Stripe handles all payments and is PCI DSS Level 1 certified. We never store your card details. Every transaction is SSL encrypted.

Question 23

What if my eSIM does not work?

Accepted Answer

First check: is data roaming enabled? Is the right eSIM selected for data? If yes and still not working, email us at support@esimagora.com — we respond within 24 hours.
