Coverage in Cambodia: what to know
Lonely Planet says Siem Reap's main attractions are well connected, but the Angkor temples vary and even Angkor Thom has sticky spots.
Lonely Planet reports Metfone has the widest rural coverage and Smart the fastest 4G. Some southern islands are very spotty, and multi-day treks in national parks may leave you offline.

Questions people ask about a Siem Reap eSIM
Does a Cambodia eSIM work in Siem Reap?
Yes. A Cambodia eSIM runs on Cambodia’s own networks (Metfone 4G, Cellcard 4G), so the same plan works in Siem Reap and everywhere else those networks reach in the country. There is no separate Siem Reap plan to buy.
How much does an eSIM for Siem Reap cost?
On 3 Nov 2026, Cambodia plans started at $0.89 and went up to $72.59 for the biggest. The shop always shows today’s price, and the price on the pay button is the price you pay.
How much data do I need for Siem Reap?
For a week of maps, rides, messages and photos most people use about 3 GB; for two weeks about 5 GB; for a month of social and video, 10 GB or more.
Will I be online when I land in Siem Reap?
Install the eSIM at home on wifi, then switch the line on as the plane lands at Siem Reap-Angkor International Airport (SAI). You are online walking off the plane, with no SIM counter and no airport wifi.
Why does my eSIM show another carrier’s name?
Many travel eSIMs are issued by one carrier and roam on local networks, so your phone can show the issuing carrier’s name while your data runs on a local network. Keep data roaming on for the eSIM.
Will it work on my phone?
Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.
When do I install it?
At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
Does it come with a phone number?
No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
What if it doesn’t work?
If we can’t issue your eSIM, we refund you in full. If it won’t install or connect, text us and we help you get connected.
