Thailand eSIM
Thailand eSIM
Thailand runs through a phone: the BTS gate, the Grab to the pier, the ferry time that moved. The plan rides TrueMove inside Thailand, and the same profile keeps working if the trip carries on into Malaysia or Singapore.

How to set up your Olysim travel eSIM in 3 steps
Choose a plan, scan the QR code that lands in your email, and switch the line on when you arrive. Install it on wi-fi before you travel - data only starts counting once you connect at the destination.
Why buy a Thailand travel eSIM from Olysim
Pick the size that fits the trip
A long weekend and a month in Thailand need very different plans, so you choose the data and the days. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
Set it up at home, land connected
The QR code arrives by email seconds after payment. Scan it on wi-fi before you leave, and the Thailand line comes alive on its own once you land and switch it on.
Someone answers, any hour
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
What is an eSIM and how does a travel eSIM work?
A SIM built into the phone
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a travel plan writes it to that slot, and your everyday SIM stays where it is.
The QR code is the plan
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.
Skip the arrivals counter
Buying a local SIM at arrivals usually means a passport, a form and a queue, in a language you may not read. An eSIM is already on the phone when the wheels touch down.

Thailand eSIM: frequently asked questions
TrueMove inside Thailand. The same profile also carries Singtel in Singapore and Maxis, Celcom and Digi in Malaysia, which is why one plan covers a Bangkok, KL and Singapore run.
The islands and the ferry ports sit inside TrueMove's national footprint, so the plan reaches them as a Thai SIM would. Mid-crossing, out of sight of either shore, reach depends on the network.
Yes. This profile spans all three on local networks, so you install once before Bangkok and stay on the same plan through KL and Singapore.
Any carrier-unlocked phone with eSIM support: iPhone XS or later, Pixel 3 or later, most Android flagships from 2019 on. Check for Add eSIM in network settings first.
Install at home on wi-fi and leave the line switched off, because it only starts when you turn it on. The arrival paperwork, the Grab app and the hotel map then work from the moment you clear immigration.
Yes. Top up from the Olysim app and it lands on the eSIM you already installed, so the profile stays put.
