The best eSIM for Thailand—the brand I love as a professional full-time travel writer

Since eSIMs exploded onto the market, staying connected while travelling has never been easier, bypassing the hassle of finding a physical SIM and the oftentimes sketchy connections that can come with it. But with over 200 brands competing for sales, it’s not always easy to decide which one to go for. As a backpacker at heart, I adored travelling the globe off-grid, without a plan and a phone, in my younger years, but now, as a professional full-time travel writer, I can’t be without strong internet—it’s essential for my work. Based now in Sri Lanka, where I love seeking out Colombo’s top restaurants and impressive Geoffrey Bawa-designed hotels, I luckily get to travel to other Asian countries a lot more, including Thailand, India, and Malaysia, all of which require a different eSIM. And after much research, I’ve concluded that when looking for the best eSIM for Thailand, Yesim is the clear winner.

What’s the best eSIM for Thailand?

I’ve tried a variety of eSIMs over the years, and some are definitely easier to use than others. When looking for the best eSIM for Thailand, Yesim stands out thanks to its solid and speedy connections, which instantly switch to the fastest network available, including 5G. It also works well across the entirety of the vibrant country, from the bustling metropolis of Bangkok and the idyllic islands of Koh Lipe and Koh Lanta, to the untamed wilderness where elephants roam.

I also really like that Yesim provides round-the-clock support should you need any assistance, and for Thailand, prices start from as little as $0.54 (£0.40) a day. 

How to decide which Yesim Thailand plan to get?

As soon as you know you’re heading to Thailand, it’s really simple to buy and activate an eSIM. Yesim’s Thailand eSIMs range from fixed plans starting at 500MB for one day, increasing to 30-day 50GB plans. And the Yesim unlimited plans start from one day, increasing to 30 days. Plus, if you’re travelling with a companion, a 10 percent discount is applied when purchasing two or more eSIMs.

There’s also a very cool Pay&Fly option, which you simply top up whenever you travel. All you need to do is purchase the plan, activate it as soon as you travel, and top it up whenever you need. It’s available for use in over 170 countries and starts from $20 (£15). This plan never expires and works on a pay-as-you-go model, meaning once you’ve purchased it, you’re good to go forever. 

How to use Yesim for Thailand?

If you’re not super au fait with technology, using an eSIM can seem a tad daunting, but it’s really very easy if you follow Yesim’s simple steps. Simply choose your preferred plan, check out, tap and install.

Typically, users are instructed to go to mobile data settings, turn on the Yesim mobile line, activate data roaming, and choose Yesim as the main connection; it really is super simple.

Is it possible to combine Thailand with other countries?

Often when I’m on a work assignment, I have to visit a handful of countries in one go, and that’s where Yesim’s Unlimited Day Pass comes in. I haven’t seen many other eSIM operators offering this option, but it’s incredibly useful if you travel a lot to many different countries and/or continents. All you need to do is pick a pack, starting from 10 days for $58.80 (£43.50) and rising to 80 days, and activate the eSIM whenever you travel. Unused days stay in your account, making it easy to activate just before you hop on the plane, bus, boat, or train to your next country.

My verdict when looking for the best eSIM for Thailand

For anyone needing to stay connected for work reasons, Yesim is the ideal eSIM for Thailand and beyond, thanks to its fast, strong, and reliable access that automatically switches to the strongest network, whatever country you’re travelling to.
