The new Siem Reap Angkor International Airport (SAI) changed the arrival math for temple visitors. It opened in October 2023 and sits about 45 km from town, far out beyond the temples, unlike the old airport that was a ten-minute hop from Pub Street. That means a ride of close to an hour before you reach your hotel, and it is exactly the stretch where you want data working to track the route and settle a fare. The simplest fix is to install a Cambodia eSIM before you travel, so you land connected and walk straight to a shuttle or a Grab. SAI does have Smart, Metfone, and Cellcard kiosks in arrivals and free terminal WiFi, but all of those still mean stopping and queuing while a tired driver waits.

SIM and eSIM Options at Siem Reap Airport
SAI is a single modern terminal, so connectivity options are easy to find once you clear immigration and collect your bag. The mobile carriers cluster their kiosks in the arrivals hall, right where you walk out.
Quick Arrivals Summary
All three Cambodian networks (Smart, Metfone, and Cellcard) run SIM kiosks in the main arrivals hall past baggage claim. A tourist SIM with 30 GB or more runs about 3 to 5 US dollars, the same as in town. Metfone's counter is often staffed 24 hours, while Smart and Cellcard typically run roughly 6:00 to 23:00, so a very late flight may find only Metfone open.
Carrier SIM Kiosks
Each kiosk sells prepaid tourist bundles and registers the SIM to your passport on the spot, which is a legal requirement in Cambodia. Smart's Traveller SIM is the popular pick for its large data allowance, Metfone is the choice if your plans reach out to the remote temples, and Cellcard suits anyone chasing the fastest city speeds. Prices at SAI are refreshingly close to street prices, so unlike many airports you are not heavily penalised for buying on arrival.
eSIM
There is no eSIM vending machine at SAI, but you do not need one. If your phone supports eSIM you can buy and install a Cambodia plan online over the airport WiFi the moment you land, or better still set it up at home before departure. That is the same purchase you could make in your living room, which is why sorting it before you fly is the cleanest route through arrivals.
Free WiFi at Siem Reap Airport
SAI offers free wireless throughout the terminal, which matters because it lets you activate an eSIM or buy a plan online the second you arrive.
Find the network
On your phone's WiFi screen, select the network named SAI AIRPORT FREE WIFI. No password is needed to join.
Accept and connect
A short portal page appears; agree to the terms to go online. When the WiFi icon shows a live connection you are set.
Use it with no clock running
The airport WiFi has no time limit, so you can take as long as you need to activate an eSIM, message your hotel, or book a ride before heading out.
Why the terminal WiFi is only a starting point
The signal covers the terminal, but your ride into Siem Reap is a 45 km run through open countryside, and the WiFi cannot follow you there. That hour on the road is precisely when you want maps and a ride app live. Use SAI AIRPORT FREE WIFI to confirm your eSIM is working, then rely on your own mobile data for the journey and the rest of the trip.
Siem Reap Airport to Town: Transit and Data En Route
Because SAI sits roughly 45 km southeast of Siem Reap, the transfer is a real journey of about an hour, not the quick hop the old airport allowed. Working mobile data over that stretch keeps your map live, lets you message your guesthouse, and helps you hold a driver to the agreed fare. Here are the main options.
| Option | Where it goes | Time | Fare (one way) |
|---|---|---|---|
| Official airport shuttle bus | 7 Makara Road, near Wat Bo and Pub Street | About 1 hour | Around 8 USD per person |
| Private taxi | Direct to your hotel | About 45 to 60 min | Roughly 25 to 35 USD (1 to 3 people) |
| Remork (tuk-tuk) | Direct to your hotel | About 60 to 90 min | Roughly 15 to 25 USD (up to 4 people) |
| Grab / PassApp | Direct to your hotel | About 45 to 60 min | From around 25 USD, app-metered |
The official shuttle bus is the budget pick at about 8 US dollars, running roughly every hour or two through the day and dropping near the Wat Bo and Pub Street areas, though it makes stops and is slower than a direct car. A private taxi or a remork takes you straight to your door, and the ride-hailing apps Grab and PassApp give you a metered price that removes the haggling, provided your phone is online to book.
Data on the road in
The route to town runs on National Road and open country, and the Cambodian networks cover it well, with Metfone the steadiest across the rural stretch. With your own eSIM or SIM live, your map, your driver chat, and your ride app all keep working the whole way in. That is far more dependable than hoping for WiFi on a bus, and it is the difference between watching your route and guessing where you are.
Why Sort Your Connection Before You Land
Given the long ride into town, there is a strong case for having data ready the instant you step off the plane rather than sorting it in the terminal.
eSIM set up in advance
Buying at the airport
The easy way to do it
Buy a Cambodia eSIM online before you leave home and add the profile while you still have your usual internet. When you touch down at SAI, switch the eSIM line on in settings and you have a Smart or Metfone signal within a minute, no airport WiFi login required. For the full network and plan rundown, see our Cambodia eSIM guide.
SAI Kiosk Prices vs an eSIM
Cambodia is unusual because the airport SIM is genuinely cheap, so the choice is more about convenience than avoiding a rip-off. Here is how the numbers compare in 2026.
| Where | Typical plan | Price |
|---|---|---|
| SAI arrivals kiosk (Smart) | ~30 GB, 15 days, with call minutes | About 5 USD |
| SAI arrivals kiosk (Metfone) | Large data bundle | About 3 to 10 USD |
| Online eSIM | Short temple stay, capped data | From about 4 USD |
| Online eSIM | Larger bucket or unlimited for a week | Around 10 to 15 USD |
The honest picture: on price alone the local SIM is hard to beat, since about 5 US dollars buys a huge Smart bundle with calls thrown in, and airport prices here match the town. The eSIM costs a touch more but earns it on convenience, arriving already online with no passport queue and no counter stop after a long flight. For a data-only traveler who wants to walk straight to a ride, that convenience is usually worth the small premium.
The verdict
Set up a Cambodia eSIM before you fly and use SAI AIRPORT FREE WIFI only to confirm it is live. Keep the arrivals kiosks in mind as a cheap backup if your phone does not support eSIM, or if you want a local number and calls. Not sure which plan suits your temple trip? Run the eSIM Finder.
Frequently Asked Questions
Can I get a SIM card in the arrivals hall at Siem Reap airport?
Yes. Smart, Metfone, and Cellcard all run kiosks in the SAI arrivals hall just past baggage claim, selling tourist SIMs with 30 GB or more for about 3 to 5 US dollars and registering them to your passport on the spot. Metfone's counter is often open 24 hours, while Smart and Cellcard typically run from around 6:00 to 23:00, so a very late arrival may find only Metfone staffed.
What is the free WiFi network at Siem Reap airport?
Look for SAI AIRPORT FREE WIFI on your phone's WiFi list. It needs no password; you just accept the terms on a short portal page to get online, and there is no time limit. It covers the terminal and is the easy way to activate an eSIM or book a ride the moment you land, but it cannot follow you on the long drive into town.
How far is the new Siem Reap airport from town, and how do I get in?
SAI is about 45 km from central Siem Reap, roughly an hour away, much farther than the old airport it replaced in 2023. Options are the official shuttle bus at about 8 US dollars per person, a private taxi at roughly 25 to 35 dollars, a remork tuk-tuk at about 15 to 25 dollars, or a Grab or PassApp car from around 25 dollars. The apps need your phone online to book.
Will I have a signal on the drive from SAI into Siem Reap?
Yes, the Cambodian networks cover the route well, with Metfone the steadiest across the rural stretch. With your own eSIM or SIM active, your map, driver messages, and ride app keep working for the full hour into town. That is far more reliable than counting on WiFi aboard a shuttle, which is patchy at best, so having your own data makes the transfer much smoother.
Is it cheaper to buy a SIM at SAI or use an eSIM?
On raw price the airport SIM wins, because about 5 US dollars buys a big Smart bundle with calls and SAI charges close to town prices. An eSIM runs a little more, from around 4 dollars for a small plan up to 10 to 15 for a larger or unlimited week. What the eSIM buys you is arriving already connected with no kiosk queue and no passport step, which many travelers happily pay a small premium for.
