What travelers say
“Used the 7-day eSIM for a week in Bangkok and Chiang Mai. Setup was straightforward on my iPhone, signal was strong almost everywhere, and the price was noticeably cheaper than Airalo. Got the QR code instantly after paying. Would buy again.”

Real-world speed
This is what your phone actually does all day
Full bars, even where Wi-Fi gives up
The best eSIM for Thailand is the one that connects where you are. Yours rides TrueMove and DTAC's 5G, the same towers locals use, so you're covered from Bangkok's BTS platforms to the island bar whose Wi-Fi password nobody actually knows.

Wondering about a physical SIM instead? Read our Thailand SIM card guide
Before you fly
An eSIM is a digital SIM built into your phone. You install a data plan with a QR code instead of swapping a physical card.
Most phones from the last few years do, including recent iPhones, Pixels, and Samsung Galaxy devices. We'll help you check before you buy.
No. eSIMs are built into modern phones by the manufacturer, so installing one doesn't touch your hardware or your existing physical SIM, and both keep working independently.
After checkout, you'll get a QR code by email. Scan it in your phone's eSIM settings to install it, and do this before you fly. When you land, turn on the eSIM and enable data roaming, and you're connected. Full step-by-step instructions come with your order.
A Thai eSIM does everything a prepaid, physical Thailand SIM card does, including unlimited data and no calls or texts needed for most tourists, but installs digitally via QR code instead of a kiosk swap. It's the easier option for most travelers: no airport queue, no lost card, and your home SIM stays active alongside it.
Yes. You can buy one of our eSIMs for Thailand online from the UK, or anywhere else, before you fly. Pay, then scan the QR code we email you in your phone's eSIM settings while you're still at home. When you land in Thailand, turn on the eSIM and enable data roaming and you're connected. Your phone needs to support eSIM and be unlocked.
Using your eSIM
You choose. Install before you fly and activate the moment you land, or start it right away if you need data sooner.
Yes. Your eSIM runs alongside your existing SIM, so calls and texts on your home number keep working as normal.
You're never cut off. Speed drops to 384kbps for the rest of that day, then resets to full speed the next day, with no top-ups needed.
Yes, tethering works. Share your MiloAway data with a laptop or another device just like you would with a regular SIM.
If plans change
No problem, you don't have to activate right away. Every plan has a 90-day window from purchase, so you can buy now to lock in the price, then activate whenever your trip actually happens.
Yes. Coverage runs across Thailand's main networks, not just the capital, from city centres to the islands. Check exact coverage for your route before you buy.
You can request a full refund within 1 hour of purchase, handy if you picked the wrong plan or changed your mind. We'll also refund you fully for an incompatible or locked device, or offer a full or partial refund if your eSIM has genuine connection issues on our end.
No. Once installed, it's locked to that device and can't be moved. You can reinstall up to 10 times on the same phone, but switching phones means a new plan.
