Key facts

South Korea 3GB/day, 1 day: what you get

Price per GB at full speed: $2.50 per GB
After 3GB in a day: Slows to 1 Mbps for the rest of the day.
When the 1 day starts: On first connection in South Korea; buy up to 180 days ahead.
Network speed: 5G where the network offers it, otherwise 4G or 3G
Hotspot: Yes. Share data with a laptop, tablet or another phone. Shared devices use the same daily allowance.
Internet location: Singapore
What this means
Your eSIM connects to local networks in South Korea, but your data joins the internet in Singapore. Apps and websites see a connection from Singapore, so some may show that country’s language, prices or content.
Maps, GPS and taxi apps still know where you really are, because they use your phone’s location, not your internet location.
Websites open as they would in Singapore, which helps if a site or app isn’t available where you are. Your bank may ask you to confirm a login from Singapore; that’s normal.

Questions about this plan

Is 3GB a day enough in South Korea?

Yes, with room for daily video streaming or sharing a hotspot with a laptop.

What happens after 3GB in a day?

1 Mbps still handles messages, maps and most web pages, but video is slow. For more full-speed data the same day, buy another day pass.

Is a bigger South Korea plan better value?

The next size up, 5GB a day for 1 day, is $14.75: $2.95 per GB of full-speed data, more per GB than the 3GB a day plan, so it only pays if you need the extra data.
