eSIM plans · AsiaCambodia eSIM: How Much Data You Need (2026)
HelloRoam bills in 31 currencies. Airalo, Holafly, Nomad and Saily bill US dollars. 11 GB covers 7 days in Cambodia at 1.5 GB a day, which is the 20 GB tier at $28.80, on a published list naming Cellcard and Metfone. Airalo lists 200+ destinations against HelloRoam's 186.
Your Cambodia data plan starts with one number: 11GB. That covers 7 days of maps, messaging and social media at 1.5GB a day on the local network your handset finds. At $28.80, the 20GB plan gives you 9GB beyond your 11GB daily total. Video callers and streamers pay $3.66/day for uncapped data on the local network your handset finds instead of guessing a GB total.
The published attachment list for Cambodia holds 2 operators: Cellcard or Metfone.
Usage varies a lot by traveler type for a 7-day trip. Light users on email and maps sit on the published 0.5 GB light band, so 4GB total. Moderate users (social media and navigation) need 1.5GB per day, so 11GB total. Heavy users (video calls and streaming) consume 3GB per day, so 21GB total. Cambodia carries 1 operator on 4G LTE with 6 plan sizes to match each tier.
Each traveler type maps to a specific plan in Cambodia. If you only use email and maps, the 5GB plan at $11.49 matches your 4GB target. Moderate travelers pay $11.49 for 5GB and get the best balance between data size and per-GB cost ($2.30/GB). If you stream video or run hotspot sessions, unlimited data at $3.66/day on the local network your handset finds is the direct answer.

Heavy use, 10 GB and up
Streaming and video calls · A full remote work day · Laptop hotspot
Working from Cambodia or streaming most nights? The match score puts Holafly first here, 96 to HelloRoam's 66. It holds the cheapest gigabyte too, $1.00 at 3 GB a day. The provider our rubric puts first scores 66 here, which is not enough. No daily-unlimited plan exists at Saily and Nomad, so a heavy trip is one large purchase. A 10 GB plan for Cambodia runs $18.90, and unlimited runs $3.66 a day.

The rate column is each provider's published entry price, worked out per gigabyte at the tier's daily usage. That is the only way a daily plan and a per-GB plan land on one scale. Published entry rates: Airalo $4.50/GB, Saily $3.99/GB, Holafly $2.99/day, Nomad $3.00/GB, HelloRoam $3.50/GB. Those are catalogue floors, not prices for Cambodia. Only one of the five publishes prices we can read per destination, and that is HelloRoam, so every Cambodia plan price above is HelloRoam's. The rest get their published floor and no destination quote.
How trip length changes your Cambodia plan
Short trips and extended stays need different data strategies. Find your trip length below.
Short trip (1-3 days)
For a weekend trip, 5GB handles moderate usage. The 5GB plan costs $11.49 on the local network your handset finds.
Standard trip (5-10 days)
A 5-10 day trip requires 11GB at 1.5GB/day. The 20GB plan at $28.80 gives moderate users enough data on the local network your handset finds.
Extended stay (14-30 days)
Extended stays of 14-30 days push past fixed plan limits. Unlimited data at $3.66/day on the local network your handset finds removes the cap.
Your Cambodia shortlist, all 5 providers
Two questions decide most e-sim purchases: how big the bundle is and how long it lasts. Here is both, next to tethering, phone numbers and each published rate.

Who you're connecting to
In Cambodia, the underlying carrier matters more than the brand on your plan.
In Cambodia, the underlying carrier affects download speeds, rural signal strength, and plan pricing. Metfone is the 4G LTE network most visitors to Cambodia spend the trip on, strongest in the metro areas. No provider states its Cambodia routing, so compare what each one does publish. Your provider choice changes the plan, the refund window and who answers the phone. It does not change the tower. If you would rather not think about gigabytes in Cambodia, Holafly sells only unlimited days, published from $2.99/day. Fair-use throttling kicks in past the daily threshold and tethering caps at 1GB. Saily is the privacy option: Nord Security VPN on every plan, published from $3.99/GB. Support is the weak spot, email in a single language with no live channel. On price alone Nomad leads the fixed plans at $3.00/GB. It sells one plan shape only, with no unlimited tier and no regional bundle. HelloRoam publishes the widest support access of the five, 63 languages on chat, WhatsApp and email around the clock, plus 180 days to refund an unactivated eSIM. It does not win price at $3.50/GB. The bottom line: 1 carrier in Cambodia all offer 4G LTE. Choose by data size first, carrier second.
HelloRoam publishes its local operator list for Cambodia, and the next section prints that list in full. The other four providers publish no equivalent list, so the cards below carry published facts about each provider instead of a carrier we would be guessing at.

Local networks a Cambodia eSIM attaches to
Good news for Cambodia: HelloRoam publishes 2 local operators there. Your eSIM attaches to Cellcard or Metfone. HelloRoam does not publish which one a given handset selects.
More than one operator means a fallback exists. If one network thins out on a train or in a rural stretch, another can carry you. 68 of the 185 destinations HelloRoam publishes list more than one operator.
HelloRoam lists no 5G operator in Cambodia, so expect 4G on the ground. None of this changes the gigabytes you need. Choose the tier by trip length, then check the list.
| Local operator | Network labels |
|---|---|
| Cellcard | 4G |
| Metfone | 4G |
Where this table came from: HelloRoam's own destination catalogue, read on 17 August 2026. That catalogue publishes an operator list for every destination it sells, and we copied it. Nobody ran a speed test to build it, and no throughput number sits behind any row.
What uses your data in Cambodia
Activity-level data breakdown for a Cambodia trip.
Streaming
Streaming moves a traveler into the heavy band, which the published benchmark puts at 3 GB a day. 7 days in Cambodia at that rate comes to 21 GB, and the 20GB plan at $28.80 is the smallest Cambodia tier that clears it. Downloading episodes over hotel WiFi keeps the day inside the 1.5 GB moderate band instead.
Navigation
The light band is 0.5 GB a day, and maps plus a ride app fit inside it. A 7-day Cambodia trip on that band needs 4 GB. The 5GB plan at $11.49 is the tier that matches.
Social media
The moderate benchmark is 1.5 GB a day, which is what social apps plus messaging draw. Across 7 days in Cambodia that is 11 GB. The 20GB plan at $28.80 covers the trip.
Work tools
Video calls run at the heavy benchmark of 3 GB a day. A 7-day working trip to Cambodia needs 21 GB, and the 20GB plan at $28.80 is the smallest tier that covers it. Audio-only calls drop the same day back toward the 0.5 GB light band.
Your Cambodia pricing notes
Here is what each plan tier costs in Cambodia: 1GB at $3.99 ($3.99/GB), 3GB at $7.99 ($2.66/GB), 5GB at $11.49 ($2.30/GB), 10GB at $18.90 ($1.89/GB), 20GB at $28.80 ($1.44/GB). The per-GB rate drops as you buy larger plans. If you use 1.5GB/day for social media and maps, the 5GB plan at $11.49 covers 4 days at $2.30/GB. Short-trip travelers spending 3-4 days in Cambodia pick 1GB at $3.99 and pay only for the data they need. If your trip runs longer than 8 days, unlimited data at $3.66/day costs less than the 20GB fixed plan at $28.80. A 30-day unlimited plan drops to $3.00/day (18% off). Streaming daily? Holafly's published $2.99/day unlimited is the shape that fits. Under a gigabyte a day, Nomad's $3.00/GB fixed rate wins the maths. Looking for the cheapest eSIM in Cambodia? The lowest destination price we hold is 1GB at $3.99 from the catalogue. Nomad publishes the lowest fixed entry rate of the five at $3.00/GB, though not a Cambodia figure we can stand behind.

Planning notes for Cambodia
Local conditions in Cambodia affect which plan tier makes sense. SIM rules: Passport required. Incredibly cheap mobile data — under $3 for 15GB
An airport SIM against a Cambodia eSIM
Airport SIM counters in Cambodia charge $2-5 for 5-20GB / 28 days and take 15-30 minutes to set up. An eSIM activates before you land and starts at $3.99 for 1GB on the local network your handset finds. You skip the queue, keep your home number active, and get connected in seconds.
How to activate your Cambodia eSIM
Choose your Cambodia data plan based on trip length and daily usage. Open your phone's cellular settings, tap "Add eSIM," and scan the QR code over WiFi before your flight.
Label the new line "Travel Data" and set it as your default data connection. Keep your home SIM active on the other line for calls and texts.
Your phone picks up a local 4G LTE network within seconds of landing in Cambodia. No SIM swap, no store visit, no registration line.
Passport required. Your eSIM provider handles backend registration, so activate before landing to avoid delays.
Common Cambodia eSIM questions
Direct answers grounded in real plan data and carrier coverage.
What plan do I need?
The published attachment list for Cambodia holds 2 operators: Cellcard or Metfone. Destination plans run from $3.99 (1GB) to $28.80 (20GB) on the catalogue, the only per-destination price feed we hold. For a 7-day trip, moderate users need about 3GB. The 3GB plan at $7.99 covers that.
How much data do I need?
The average smartphone user consumes about 15GB per month at home. A 7-day trip to Cambodia uses about 3GB, roughly 20% of a month's data. That is the 1.5 GB moderate band, which covers maps, social media and messaging. Cambodia has decent WiFi in hotels and cafes, which offsets about 15% of your data needs.
Which provider is cheapest?
Cambodia fixed plans start at $3.99 for 1GB on the local network your handset finds. Unlimited runs $3.66/day ($25.62/week). Both are catalogue prices. Light users save on fixed. Unlimited passes the largest fixed bundle at $28.80 after 8 days. Across published floors, Nomad is the cheapest fixed rate at $3.00/GB.
Is an eSIM worth it?
An eSIM saves money and time in Cambodia. Airport SIM cards cost $2-5 for 5-20GB / 28 days after a 15-30 minutes wait. A 20GB eSIM costs $28.80 for 11GB and activates before you board. It runs on the local network your handset finds, the same network airport SIMs use. On published plan shape and our rubric, HelloRoam is the closest fit of the 5, and its own entry rate is $3.50/GB.
eSIM vs SIM card?
Use both in Cambodia: keep your home SIM for calls and add an eSIM for data. Cambodia eSIM plans start at $3.99 for 1GB on the local network your handset finds, a catalogue price. That avoids the 15-30 minutes airport SIM queue and the $2-5 for 5-20GB / 28 days counter price. Cambodia requires SIM registration with passport, which adds time at the counter.
How to set up?
Setting up an eSIM for Cambodia takes about 5 minutes. Step 1: Buy a plan sized to your trip. (Cambodia plans start at $3.99 for 1GB on the catalogue.) Step 2: Scan the QR code or use the direct install link. Step 3: Turn on the eSIM line in your phone settings. Step 4: Enable data roaming and set the eSIM as your data line. The plan connects to a local network when you arrive.
Plan match by traveler profile
Each profile maps to a specific plan size and provider for Cambodia.
Backpacker
A backpacker in Cambodia needs 7 GB for maps and messaging over 14 days. The 10 GB plan covers that at $18.90, or $1.89 per GB, on the local network your handset finds. HelloRoam sells the shape this trip needs; Nomad publishes the lower fixed floor.
On the 0.5 GB light band, backpackers use 4GB across 7 days. The 5GB tier at $11.49 fits that target on the local network your handset finds.
Business traveler
A business traveler in Cambodia needs 15 GB for video calls and uploads over 5 days. The 20 GB plan covers that at $28.80, or $1.44 per GB, on the local network your handset finds. On published plan shape, HelloRoam is the closest fit of the five, and Airalo still reaches more places at 200.
A 7-day business trip in Cambodia needs 21GB minimum. Unlimited data at $3.66/day on the local network your handset finds keeps calls stable.
Family group
A family traveler heading to Cambodia should budget 14 GB for social media and navigation across 7 days. That lands on the 20 GB plan, $28.80 on the local network your handset finds. Of the five we score, HelloRoam publishes the plan shape that fits, at an entry rate of $3.50/GB.
A family of 3 sharing data uses 32GB over 7 days. The 20GB plan at $28.80 per device keeps everyone connected on the local network your handset finds.
Digital nomad
A digital nomad heading to Cambodia should budget 75 GB for remote work and streaming across 30 days. That lands on the 20 GB plan, $28.80 on the local network your handset finds. The shape fit here is Holafly, which answers support in 10 languages and refunds for 180 days.
Remote workers run the 3 GB heavy band for uploads and calls. The 20GB plan at $28.80 handles 21GB over 7 days on the local network your handset finds.
Your questions, answered
How many gigabytes per day should I budget in Cambodia?
Three habits, three daily rates in Cambodia. The navigator, who uses maps, WhatsApp and quick searches, runs 0.5 GB a day and 4 GB across 7 days. The social traveler, on Instagram, maps and daily browsing, runs 1.5 GB a day and 11 GB, and the 20 GB plan at $28.80 covers the moderate figure. The remote worker, on video calls and cloud sync, runs 3 GB a day and 21 GB on the local network your handset finds.
Which plan shape fits my Cambodia trip, fixed tiers or unlimited days?
Both shapes reach Cambodia, and the five providers we score do not offer them equally. Holafly publishes unlimited daily plans across the catalogue. HelloRoam and Airalo publish them for selected destinations only. There is no unlimited option from Nomad and Saily, fixed tiers only. Holafly publishes nothing by the gigabyte, so light users have no small plan to buy. On the destination price list, fixed tiers open at $3.99 for the 1 GB plan and unlimited days open at $3.66. The shortest unlimited commitment sold here is 1 day at $3.51. Nomad publishes the lowest fixed entry rate of the group; Holafly is the reference point for the unlimited shape.
Which eSIM plan fits a light or heavy data user in Cambodia?
If you only check maps and send messages in Cambodia, 4 GB covers 7 days. The 5 GB plan at $11.49 handles that at $2.30/GB. If you scroll social media and browse regularly, step up to the 20 GB plan at $28.80 ($1.44/GB). If you stream video or work on video calls, you need 21 GB, and the 20 GB plan at $28.80 ($1.44/GB) is the largest tier sold here, so a heavy pace needs a second purchase or an unlimited plan.
What should I check on my phone before I buy a Cambodia plan?
If your phone is an iPhone XS or newer, a Samsung Galaxy S20 or newer, or a Google Pixel 3 or newer, it can run an eSIM profile. If it is carrier-locked, ask your operator to unlock it before you buy anything for Cambodia. Dial *#06# and look for an EID line, because that number is what the profile installs against. Some sites write e-SIM, others write e SIM. Same profile either way.
What starts the clock on a Cambodia plan, the purchase or the landing?
Three events, one clock. Purchase: no countdown. Installing the QR code over WiFi: still no countdown. First connection to a Cambodia mobile network: the countdown begins. That separation is what lets you set the phone up at home and arrive already connected. The 1 GB plan at $3.99 suits a short stay. The 20 GB plan at $28.80 suits a longer one. Buy within 3 days of departure and the window lines up with the trip.
Is Cambodia well-covered by travel eSIM networks in Asia?
For a Asia trip centred on Cambodia, the picture is simple. 1 operator (Metfone) deliver 4G LTE service, and travel eSIMs ride the same infrastructure as local SIMs. Coverage is strongest in urban centres and transport hubs. The 5 GB plan at $11.49 ($2.30/GB) fits a standard Asia visit. If the trip grows another leg, check reach before loyalty. Reach is not equal across the five. Airalo, Nomad and Saily at 200, HelloRoam at 186 and Holafly at 160.
Which activities use the most mobile data in Cambodia?
The photo sharer and the navigator both live inside the 1.5 GB moderate band in Cambodia. The streamer and the remote worker both live on the 3 GB heavy band. That is the whole split, and it is the split the tier ladder is built around. The 5 GB plan at $11.49 covers a moderate traveller on the local network your handset finds, at $2.30/GB.
How do I match a Cambodia plan tier to the number of nights I am staying?
Count the nights, multiply by 1.5 GB, and buy the first tier above that number. For Cambodia at a moderate pace that maps out as: 1 to 2 nights takes the 3 GB plan at $7.99 ($2.66/GB); 3 nights takes the 5 GB plan at $11.49 ($2.30/GB); 4 to 6 nights takes the 10 GB plan at $18.90 ($1.89/GB); 7 to 13 nights takes the 20 GB plan at $28.80 ($1.44/GB). The 20 GB plan holds the lowest per-GB rate here at $1.44/GB. Add 20% on top if you stream video or run navigation for whole days, because a tier that fits exactly leaves you rationing on the last morning.
How many days must I commit to for unlimited pricing in Cambodia?
You commit to at least 1 day, which costs $3.51 in Cambodia. If your trip runs longer, book the days upfront: the 30-day tier costs $3.00 a day, 18% below the $3.66 base rate. If you extend later instead, you pay the base rate for the extra days. Full 4G LTE speed runs to 2GB a day before fair-use terms apply.
Which provider backs up a mis-sized Cambodia plan?
Travelers who buy months ahead lean on the refund window; travelers who buy the night before lean on support. For the first group: HelloRoam and Holafly publish 180 days, Nomad and Saily 30 days and Airalo 14 days, all on an unactivated eSIM. For the second: HelloRoam publishes 63 languages over live chat, WhatsApp and email, around the clock, and Airalo sits at the other end of the refund ladder with 14 days. Pick the backstop that matches how you buy for Cambodia. Sizing up first is still cheaper than any refund: the 20 GB plan holds the lowest rate here at $1.44/GB.
