New Year 2027 eSIM: when to buy for a 5–7 day trip

In short

Buy early, but not too early: most plans must be activated within 60 days of purchase. Flying on 28 December? Buy from early November on.
Maps, chat and social media for 5–7 days: by the GB is cheapest, from ฿109 (≈ $3.60)
Live video, countdown clips or sharing with the family: unlimited at 10 Mbps

Prices are from Vacay, the eSIM store GoeSIM partners with, on 21 Oct 2026, in baht. Check the current price before you buy.

By the GB

Destination · plan	5 days	7 days
Japan · DoCoMo 5GB	฿109≈ $3.60	฿119≈ $3.93
Korea · Best Korea 5GB	฿109≈ $3.60	฿119≈ $3.93
Taiwan · Best Taiwan 5GB	฿119≈ $3.93	฿129≈ $4.26
Europe · Europe Special 10GB	฿179≈ $5.91	฿189≈ $6.24

Most people use about 1GB a day or less for maps and social media. Europe trips tend to be longer, with more train days, so 10GB is the safer pick there.

Unlimited at 10 Mbps

Destination · plan	5 days	7 days
Japan · KDDI Unlimited	฿269≈ $8.88	฿369≈ $12.18
Korea · Best Korea Unlimited	฿329≈ $10.86	฿449≈ $14.82
Europe · Europe Special Unlimited	฿329≈ $10.86	฿449≈ $14.82
Taiwan · Best Taiwan Unlimited	฿379≈ $12.51	฿519≈ $17.13

10 Mbps handles video, video calls and stories. For long live streams or big uploads, see the full-speed options in each country guide.

When to buy

Most plans start counting when you arrive, so you can buy and install in Thailand without losing days.

But they must be activated within 60 days of purchase, counted from the day you buy to the day you land.

Example: flying on 28 December, anything bought from about 29 October is inside 60 days. Buying a few days before you fly is safer if plans might change.

New Year is busy: buy at least 2–3 days ahead so there's time to contact support if the QR code is slow to arrive.

Countdown night

Countdown spots are packed, and every network can slow down or fail to send photos around midnight. Agree on a meeting point and screenshot the route back to your hotel.

KDDI's Japan plans roll over to a new day at midnight Japan time (22:00 in Thailand); most others run in 24-hour cycles from first use. Land late and KDDI's first day is short.

Families: one unlimited plan with a hotspot works while you stay together, but in countdown crowds separate plans are safer.

Keep your Thai SIM on for bank codes: see how to get Thai bank OTP codes abroad.
