Korea eSIM FAQs, answered clearly

Answers about your LG U+ plan, setup and travel in Korea.

Is the data really unlimited?

Yes. This LG U+ plan has no daily data cap or usage-based slowdown. Use unlimited data throughout your selected plan, with no fair-use data threshold.

How fast is the LG U+ eSIM?

LG U+ measured peak 5G speeds of 960 Mbps. Your actual speed depends on coverage, your device and network conditions. The eSIM also connects to 4G LTE where 5G is unavailable.

Can I share data through a hotspot?

Yes. Hotspot is unlimited, with no separate data allowance. Share your connection with a laptop, tablet or travel partner throughout your plan.

Which network and IP address will I use?

You connect to LG U+'s local 5G and 4G LTE network with a Korean IP address.

Does this eSIM include calls or SMS?

No. This is a data-only eSIM with no phone number. Use WhatsApp, KakaoTalk or FaceTime over mobile data.

If you need calls and SMS, see our Korea eSIM with a Korean number.

Do I need to register my passport?

No passport registration is required for this LG U+ data plan. Install your eSIM before departure, then switch it on when you arrive in Korea.

Will this eSIM work on my phone?

Your phone must support eSIM and be carrier-unlocked. Check your exact model and regional version on the compatible device list before buying.

When does my plan start? Can I install it early?

Your plan starts with your first data use in Korea, and each day lasts a full 24 hours. A late arrival does not cost you a day.

On Wi-Fi, install before you fly using the ByteSIM App or your emailed QR code. Keep the eSIM off until you arrive. Installation alone does not start your plan.

Can I extend or top up this plan?

This plan cannot be topped up or extended. Choose 1 to 90 days when ordering. If your trip runs longer, buy a new plan for the extra days.

Can I reinstall or download the eSIM again?

Once enabled on a device, the eSIM cannot be reinstalled or downloaded again. Keep it installed while your plan is active.

For help, contact our 24/7 support team on WhatsApp or email.

What should I do if I cannot connect in Korea?

Check that your ByteSIM eSIM is turned on and selected for mobile data. Turn airplane mode on and off, then restart your phone if needed.

Still offline? Connect to Wi-Fi and contact our 24/7 team on WhatsApp or email. Keep the eSIM installed so we can help troubleshoot.

Can I get a refund if my plans change?

An eligible unused eSIM may qualify for a full refund if requested within 180 days of purchase. Eligibility depends on installation, activation, usage and the reason for your request.

For connection issues, contact support while your plan is valid. See the full refund policy.
