Cambodia eSIM
Cambodia is reachable by air and overland, and most itineraries pair Phnom Penh with Siem Reap. Data matters here for hailing a tuk-tuk through an app, buying the Angkor pass ahead of time and messaging accommodation, which is mostly done over chat. Arrival formalities now also start with an online traveller registration before you reach the checkpoint.

What happens when your GB runs out
A GB plan is a fixed amount of data. When it is used up, data on that eSIM stops and nothing is charged automatically, but you can top up the same eSIM without a new QR code, and check what is left any time from your order page.

How much data you actually need
Around 800MB–1.5GB a day covers maps, chat and photos. If you film at Angkor and upload each evening, budget nearer 2GB a day.
When you land
By air you arrive at Phnom Penh (PNH), Siem Reap–Angkor (SAI) or Sihanoukville (KOS). Overland from Thailand the main crossing is Aranyaprathet–Poipet, with Hat Lek–Koh Kong further south, while travellers from Vietnam usually cross at Bavet. Allow time at the border and have your line running before you reach the checkpoint.
Where coverage changes
Phnom Penh and Siem Reap are covered across town, and the main Angkor temple circuit works. Outlying temples such as Beng Mealea and Koh Ker thin out. The Cardamom Mountains, Ratanakiri and Mondulkiri provinces, and the islands of Koh Rong and Koh Rong Sanloem are uneven and slow in many spots.
Cities travellers ask about
- Phnom Penh — Covered city-wide and along the riverfront; app rides work easily.
- Siem Reap — Good in town and on the main temple circuit; outer ruins drop off.
- Battambang — Fine in the town centre, sparser on the roads out into the countryside.
- Kampot and Kep — Usable by the river and crab market; patchy up on Bokor mountain.
- Koh Rong — Passable on the main beach; the quiet side and interior have almost none.

Apps to install before you fly

- PassApp, the tuk-tuk hailing app locals use most
- Cambodia's online arrival registration for travellers
- Google Maps with offline areas for the provincial routes

FAQ
Will the signal switch over automatically at the Poipet border?+
In practice your phone may hold on to a Thai tower for a while, because the signal carries across the border. The reliable fix is to toggle flight mode once after you clear the checkpoint, forcing the handset to search for a network again, and to confirm data roaming is enabled on the eSIM line.
Does data work throughout the Angkor complex?+
The main circuit — Angkor Wat, Bayon and Ta Prohm — works normally, since it sits close to Siem Reap town. Head out to distant temples such as Beng Mealea or Koh Ker and the signal drops off sharply. Download the route map and save your driver's number before you leave your accommodation in the morning.
Do I need to complete the online arrival registration first?+
Cambodia now has travellers submit arrival details online and show the result at the checkpoint. Complete it while you still have Wi-Fi and screenshot the confirmation, because filling it in at a busy land crossing wastes a lot of time. Check the current requirements shortly before you travel, as the process has changed more than once.
How should I prepare for Koh Rong?+
Book the boat and your stay while you are still in Sihanoukville, and screenshot the confirmations and the address. On the island the signal is decent only around the main beach; the quiet side and the inland paths have almost nothing, and the last boat back leaves earlier than most people expect.
When does a Cambodia eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
