What Cambodia data actually costs
Cambodia travel eSIM prices look random until you convert every plan to one number: the real cost per gigabyte. Here is what that reveals right now.
The cheapest plan at each size, 30 days
| Data | Cheapest provider | Total | Price per GB | |
|---|---|---|---|---|
| 50 GB | Airalo | $49 | $0.98/GB | Get plan ↗ |
| 25 GB | Ubigi | $39 | $1.56/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 20 GB | Sim Local | $26.25 | $1.31/GB | Get plan ↗🏷 10% off with code ATESIM |
| 10 GB | Sim Local | $16 | $1.60/GB | Get plan ↗🏷 10% off with code ATESIM |
| 5 GB | Sim Local | $10.75 | $2.15/GB | Get plan ↗🏷 10% off with code ATESIM |
| 1 GB | Yesim | $4.61 | $4.61/GB | Get plan ↗🏷 15% off with code TRAVELCITY |
Cost per GB rises from $0.98/GB at 50 GB to $4.61/GB at 1 GB. Buying a little more data than you expect to use is almost always cheaper per gigabyte than buying exactly what you need.
The "unlimited" trap
The same words, unlimited for 30 days, cover a wide price range, and most plans slow down after a daily threshold that the label hides.
| Provider | Unlimited, 30 days | Fair-use cap | |
|---|---|---|---|
| Maya | $49.99 | 3 GB/day, then 10 Mbps source | Get plan ↗🏷 10% off with code ATESIM |
| Ubigi | $66 | Not published | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| Airalo | $72.50 | 3 GB/day, then 1 Mbps source | Get plan ↗ |
| GigSky | $74.99 | 2.5 GB/day, then reduced, but not below 100 kbps source | Get plan ↗🏷 15% off with code ATESIM |
Unlimited 30 day plans run from $49.99 to $74.99, a spread of about 50 percent, for a label that means the same thing on paper. Check the daily cap before you buy, especially if you plan to tether a laptop.
Do not overpay for coverage you will not use
If your whole trip is in Cambodia, a Cambodia only plan is far cheaper per gigabyte than a Asia or global plan carrying the same data. Same provider (Sim Local), same 20 GB, 30 days:
| Sim Local plan | Price | Price per GB | |
|---|---|---|---|
| Cambodia only | $26.25 | $1.31/GB | Get plan ↗🏷 10% off with code ATESIM |
| Asia | $35 | $1.75/GB | Get plan ↗🏷 10% off with code ATESIM |
| Global | $35 | $1.75/GB | Get plan ↗🏷 10% off with code ATESIM |
A Cambodia only plan costs much less per gigabyte than a regional or global plan with the same data. Only pay for the wider plan if you are actually crossing borders on this trip.
Which network does your Cambodia eSIM use?
This is the question that decides your real signal, and almost no comparison site answers it. Your travel eSIM connects to one or more local networks as a visitor, and that choice matters the moment you leave the big cities, because rural coverage varies a lot between them.
| Provider | Host network | Status |
|---|---|---|
| Airalo | Smart Axiata | Confirmed |
| GigSky | Not publicly disclosed | Confirming |
| Ubigi | Metfone | Confirmed |
| Nomad | Not publicly disclosed | Confirming |
| Saily | Not publicly disclosed | Confirming |
| Yesim | Smart Axiata, Cellcard, Metfone (provider-listed) | Confirmed |
Ubigi names Metfone on a published operator page and field tests show Airalo connecting to Smart Axiata; Yesim lists all three national carriers without stating which one your eSIM attaches to, while GigSky, Nomad and Saily do not disclose their Cambodian host network.
Coverage by where you are going
- Phnom Penh has the strongest signal, with field tests on Smart showing around 73 Mbps download on 4G and 5G live since January 1, 2026.
- Siem Reap town holds steady LTE, but signal drops at the Angkor Wat temple complex and on the road out to Banteay Srei no matter which provider you use.
- Sihanoukville and the southern coast get 4G, with 5G added in the January 2026 rollout that reached 21 cities and provinces within the first month.
- Smart Axiata and Metfone have the widest national reach, and Cellcard also covers the country but is used less often by travel eSIMs.
- Rural stretches such as Kampong Cham can fall back to slow EDGE, so coverage is not uniform once you leave the main towns.
- There is no metro or subway in Cambodia, and on intercity roads you generally keep 4G along the major routes between Phnom Penh, Siem Reap and the coast.
Travel eSIM vs a local Cambodia SIM
A travel eSIM is the simplest option for a short trip because it activates before you land and needs no passport registration. Airalo's Connect Cambodia runs from about $4 for 1 GB up to $49 for 50 GB over 30 days, and its unlimited 30-day plan is $72.50 with a 3 GB daily cap. Saily's Cambodia 10 GB for 30 days is around $24, and Ubigi sells 10 GB for 30 days at $20. Prices are higher per gigabyte than a local SIM, but you skip the queue and keep your usual number active for messaging.
A local prepaid SIM from Smart, Metfone or Cellcard is cheaper if you use a lot of data and do not mind registering. Tourist packages are sold at Phnom Penh and Siem Reap airports and at phone shops in town, often bundling several gigabytes for a few dollars. Cambodian rules require every SIM to be registered against a passport or national ID, so bring your passport. This route makes most sense for longer stays or heavy data use.
Quick rule: For a trip under two weeks use an eSIM; for a longer stay or heavy streaming buy a local Smart or Metfone SIM.
Cambodia's networks are Smart Axiata, Metfone and Cellcard, all SIM cards must be registered with a passport or ID, and tourist SIMs are sold at the international airports and city phone shops.
How a Cambodia travel eSIM works
A travel eSIM replaces expensive roaming with a cheap local data plan you activate in seconds. There is no plastic SIM and no airport queue. Roaming with your home carrier can run 6 to 12 dollars a day, so a week easily tops 50 to 80 dollars for service you already pay for at home.
Three things to get right:
- Check your phone supports eSIM before you buy.
- Install the eSIM at home over WiFi, but wait to activate it until you land, because the validity period usually starts on activation.
- Keep your physical SIM in the phone for calls and texts on your normal number.
How we rank Cambodia eSIMs
Every plan on this page is sorted by real price per GB (total price divided by included data, normalised to USD), so a cheap-looking 1 GB plan cannot outrank a better-value 10 GB one. We refresh prices daily and only list providers with a track record of activating on arrival. We earn a small affiliate commission when you buy through our links. It funds the price tracking and never changes the order you see.
Cambodia travel eSIM FAQ
Which local network do these eSIMs use in Cambodia?
Ubigi connects to Metfone, which it lists on its published operator page. Field tests of Airalo show it connecting to Smart Axiata. GigSky, Nomad and Saily do not publicly name their Cambodian host network, and Yesim lists all three national carriers on its site without saying which one your eSIM attaches to.
Is 5G available in Cambodia?
Yes. Cambodia switched on commercial 5G across all three operators on January 1, 2026, starting in Phnom Penh and parts of Siem Reap and other provinces. Smart Axiata expanded from 283 to more than 600 sites across 21 cities and provinces within the first month. You need a plan and phone that support 5G to use it, and 4G remains the norm in most rural areas.
Will my eSIM work at the Angkor Wat temples?
Coverage in Siem Reap town is reliable, but signal weakens inside the Angkor Archaeological Park and on the road to Banteay Srei, and this happens on every provider. Download offline maps and any tickets or guides before you go. Once you are back in town, LTE returns to full strength.
Are the unlimited plans genuinely unlimited?
Not without limits. Airalo throttles to 1 Mbps after 3 GB per day and GigSky slows down after 2.5 GB per day. Saily's unlimited plan gives 30 GB across the 30 days before dropping to 1 Mbps, and Yesim applies a fair usage policy that it does not spell out by the gigabyte for Cambodia. Ubigi and Nomad do not sell an unlimited Cambodia plan.
Is an eSIM or a local SIM cheaper?
A local Smart or Metfone SIM is cheaper per gigabyte and better for heavy use, but it requires passport registration at a shop or airport counter. An eSIM costs a little more yet activates instantly and keeps your home number reachable for messaging. For a short holiday the eSIM convenience usually outweighs the price difference.
Can I use a Cambodia eSIM in Thailand, Vietnam or Laos?
A single-country Cambodia plan works only in Cambodia. If you are crossing into Thailand, Vietnam or Laos on the same trip, choose a regional Asia plan instead, which Airalo, Nomad, Ubigi and Saily all offer. Check the plan's country list before buying so your data keeps working after the border.
