GoeSIM (goesim.asia) is a Thai site that helps travellers pick a travel eSIM. We compare plans by destination, trip length and data, show prices in Thai baht (with US dollars on the English pages), and write guides on the questions travellers actually run into.
Who runs this site
GoeSIM is run by a small team in Thailand. We write the guides, check the prices and look after the site ourselves, and we also answer travel eSIM questions on the Thai forum Pantip. Every article on the site is written by the GoeSIM team.
How we check prices
- Every plan's prices and options (days, data, speed) come from Vacay's website.
- We check them against the live site every week. When a price or plan changes, we update the destination page and the related articles.
- Every destination page shows the date its prices were last checked, under the plan picker.
- Networks, when the days start counting, hotspot sharing and phone numbers come from Vacay's plan pages. Where two sources disagree, we follow the plan page and say so.
- The seller's price can change before we update. The price you see at checkout is the one that counts.
How we pick the recommended plans
- The recommended data size assumes typical use of about 1.5 GB a day (maps, chat, social media and some video).
- For Unlimited plans we show whether the speed is 10 Mbps or full speed, and any daily full-speed allowance.
- Where a local carrier's SIM is cheaper or better than a roaming plan, we include it with its limits, such as no balance check or days that start at once.
- We say plainly when a plan is data only, with no phone number.
Why every buy button goes to Vacay
GoeSIM is an affiliate partner of Vacay. When you buy through our links, Vacay pays us a commission and you pay the same price. So the comparisons here are between plans sold by Vacay, not every seller on the market.
Vacay sells its own roaming plans and local carriers' SIMs, such as KDDI in Japan, AT&T in the USA, Orange in Europe and Wintel in Vietnam, so several kinds can be compared in one place. Prices are in baht, and the QR code arrives by email right after payment.
The commission rate is the same for every plan and carrier, so we have no reason to push one over another, and we recommend the cheapest plan that covers the trip.
