Prices are converted to SGD at indicative daily exchange rates (updated 2026-10-10); you pay in the brand's checkout currency, so the final amount can differ slightly. Cost per GB = price ÷ total data; unlimited plans are compared on price and cost per day. Plan details are collected automatically from each brand's site every week: confirm before you buy.

Frequently asked questions

What is the cheapest travel eSIM for South Korea?

Right now the lowest cost per GB is BNESIM's 20GB / 30-day plan at S$12.90 (about S$0.64 per GB). The cheapest plan overall for a typical trip is Instabridge's 1GB / 7-day plan at S$2.56. Prices change, so check the table above, which is updated weekly.

How much data do I need for South Korea?

As a rough guide, maps and messaging use around 0.3 to 0.5GB a day, while social media and some video can use 1 to 2GB a day. Multiply by the days of your trip and add a buffer; unlimited plans suit heavy users and tethering.

Is a travel eSIM better than roaming in South Korea?

A travel eSIM usually costs less than daily roaming passes and avoids swapping SIM cards, but it depends on your home plan's roaming charges. Compare the price per day here with your telco's roaming pass, and make sure your phone is unlocked and supports eSIM.

Does a travel eSIM come with a phone number?

Most travel eSIMs are data-only: you use WhatsApp, iMessage or other apps for calls and messages. A few brands include a phone number or voice and SMS; the table on this page shows which, using the 'Phone number' and 'Voice / SMS' columns.

How is the cost per GB calculated?

Price divided by the total data in the plan, after converting the brand's price into your currency at indicative daily exchange rates. Unlimited plans are compared on price and cost per day instead.

Can I use an eSIM instead of a physical SIM?

Many recent phones support eSIM, and several providers offer it for new lines. Check that your phone is unlocked and eSIM-capable, then ask the provider for eSIM activation. Search PlanSifu for 'eSIM' to find plans that mention it.

How does PlanSifu pick the 'best' plans?

Automatically, from the prices and specs we collect from provider websites every night: for example price per GB, speed or contract terms. Plans limited to an age group are left out of the headline picks. We may earn a commission if you apply through our links, but that does not change the ranking.
