Travel eSIM vs Firsty
Firsty is a travel eSIM provider; we sell on the website with no app, and support in Thai, English and Chinese.

What is Firsty?
Firsty is a travel eSIM provider: it sells data plans you install on a phone to get internet while travelling, without buying a SIM at the destination. Beyond that we do not state facts about Firsty, because plans, prices and terms change. Check Firsty's official channels directly.

How to compare Firsty fairly with any other eSIM
Before reading any review or comparison, this page included, start from your own trip rather than a brand name: which country, how many days, and how much maps, video or hotspot sharing you will do. Then compare each provider against those answers on the day you buy.
- Destination: is there a plan for the exact country you are visiting?
- Purchase channel: web or app, and does it need an account?
- Refunds: when are they possible and on what terms?
- Support language: can you get help in a language you are comfortable in?
- Live price: look on the day you buy, not at figures from old reviews

If you would rather not install an app
A travel eSIM from esimonline.asia is bought on the website: pay, receive the QR code by email, and install it from your phone's settings with no app. Support is in Thai, English and Chinese.
Before buying an eSIM from anyone
Confirm that your phone supports eSIM and is carrier-unlocked. Our data-only eSIM has no phone number or SMS, so if you need SMS verification codes, keep your primary SIM active, and install the profile ahead of time on Wi-Fi.
