eSIM for Cambodia – Mobile Data from Angkor to Phnom Penh

Coverage data as of Q1 2026. Pricing current as of March 2026.

How Bcengi TravelPass Works in Cambodia

Cambodia trips are typically short — three to five days in Phnom Penh, a few more in Siem Reap, maybe a quick stop on the coast — and they almost always sit inside a longer Southeast Asia itinerary. Buying a local tourist SIM package for that kind of trip means paying for data you won't use. Bcengi TravelPass is a pay-as-you-go data eSIM that charges you only for the data you actually consume, at $4.58/GB on the Metfone network.

TravelPass is data-only (no voice or SMS) and runs alongside your existing SIM — your home number stays active for calls and texts while TravelPass handles mobile data. Add credit before you leave, scan the QR code to install, and activate data roaming when you land. No shop visit, no registration form, no Khmer-language interface to navigate at the airport. See current pricing for full rate details.

Daily Data Cost in Cambodia

At $4.58/GB, daily costs depend heavily on how you use your phone. Temple days at Angkor are naturally low-data — you're offline most of the time. City days in Phnom Penh or Siem Reap town are higher, especially with Grab rides and Google Maps navigation.

  • Light (maps, WhatsApp, occasional web) — ~200 MB/day, ~$0.92
  • Moderate (social media, navigation, Grab calls) — ~500 MB/day, ~$2.29
  • Heavy (video calls, uploads, streaming) — ~2 GB/day, ~$9.16
  • Offline day (temple complex, river cruise, flight) — 0 MB, $0.00

A typical five-day Cambodia stay — two days in Phnom Penh, two in Siem Reap, one transit or temple day — runs around 1.5–2.5 GB total, costing roughly $7–$11. Local tourist SIMs are cheaper per GB (Smart and Cellcard sell 10–20 GB packages for $5–10), but those require buying in-country and the data expires. For a short trip where you might use only 2 GB, PAYG math often works out comparable or better.

Why eSIM Makes Sense for Cambodia

Three factors make PAYG eSIM the logical choice for most Cambodia visitors.

Short trip, part of a larger itinerary. Cambodia rarely stands alone. Most visitors arrive from Bangkok or Ho Chi Minh City and continue onward. A single eSIM balance covers the whole trip — no new SIM at each border, no leftover credit on a Cambodian SIM you'll never use again.

Temple days create natural data gaps. Angkor Wat and the surrounding temple complex cover 400 square kilometers of jungle. Some temples have decent signal; many remote ones don't. Your data consumption drops to near zero on full temple days, which makes per-MB billing far more efficient than a daily flat-rate package.

No SIM registration barrier. Buying a local SIM in Cambodia technically requires passport registration, and quality varies by vendor. Airport kiosks can be slow. With an eSIM installed before departure, you step off the plane at Phnom Penh International or Siem Reap International with working data — no queue, no language barrier at the counter.

Cross-Border and Multi-Country Travel

Cambodia is almost never the only stop. The standard Southeast Asia circuit pairs it with Vietnam, Thailand, or both. Common overland crossings include Poipet (Cambodia–Thailand) and Bavet/Moc Bai (Cambodia–Vietnam). The Bcengi TravelPass balance carries across borders — the same eSIM works in Vietnam and Thailand at their respective per-GB rates, so you're not managing separate SIMs or top-ups at each crossing.

For context on neighboring country costs and coverage, see the Thailand eSIM guide and Vietnam eSIM guide. If your itinerary extends further, Malaysia and Indonesia are also covered.

Mobile Infrastructure in Cambodia

Cambodia's mobile network is developing-tier. Coverage is solid in the main tourist hubs but thins out quickly outside them.

Metfone is Cambodia's largest operator by subscriber base and the network Bcengi TravelPass connects through. It runs 4G LTE in Phnom Penh, Siem Reap, and Sihanoukville, with 3G coverage extending to provincial towns and main highways. Rural coverage outside tourist corridors is patchy.

Smart Axiata and Cellcard are the other major operators and offer competitive tourist packages, but TravelPass operates on Metfone. In practical terms, coverage differences between the three are small in places tourists actually visit — the gaps appear in rural areas where all three networks are sparse.

4G speeds in central Phnom Penh and Siem Reap town are adequate for navigation, messaging, and video calls. Congestion can occur at peak tourist times around Angkor — download anything you'll need for temple day offline, before you leave the hotel.

Connectivity by Location

Phnom Penh (riverside, Russian Market, Royal Palace area)

Phnom Penh has the strongest and most consistent 4G coverage in the country. The riverside promenade, BKK1 neighborhood, Russian Market, and Tuol Sleng area all have reliable signal. Indoor coverage in restaurants, cafes, and guest houses is generally good. Tuk-tuk navigation and Grab pickups work without issue across the city.

Siem Reap and Angkor Wat

Siem Reap town has good 4G coverage — Pub Street, the Old Market, and the main hotel strip all work well. The Angkor Archaeological Park is a different matter. Angkor Wat itself and the main circuit temples (Bayon, Ta Prohm, Banteay Srei) have usable signal, but many of the outer temples — Beng Mealea, Koh Ker — are in areas with 3G or no signal. Download offline maps the night before any temple day.

Sihanoukville and the coast

Sihanoukville town has reasonable 4G coverage, though the city's character has changed significantly in recent years. The nearby islands — Koh Rong, Koh Rong Samloem — have basic coverage near the beach areas but expect gaps inland and on smaller islands. Ferry crossings have no signal.

Between cities (Route 6: Phnom Penh to Siem Reap)

The main road between Phnom Penh and Siem Reap (approximately five to six hours by bus) passes through provincial towns with variable coverage. Signal is present in towns like Skun and Kampong Thom but drops in rural stretches. Expect interruptions on long bus journeys — download podcasts or offline content before departure.

WiFi Landscape

WiFi is available throughout Cambodia's tourist infrastructure but reliability varies widely. Hotels in Phnom Penh and Siem Reap that cater to international visitors generally offer usable WiFi — speeds are inconsistent but sufficient for messaging and light browsing. Guesthouses and budget accommodation are more unpredictable.

Cafes and restaurants in tourist areas often have WiFi, though speed and stability depend on the venue. Co-working spaces in Phnom Penh (BKK1 area) are a reliable option if you need consistent connectivity for work. Public WiFi in markets, temples, and outdoor areas is essentially nonexistent.

Outside Phnom Penh and Siem Reap, don't count on hotel WiFi being usable. Guesthouses in smaller towns and coastal areas often have unreliable or slow connections. Mobile data fills the gap — which is precisely where having a working eSIM matters more than in the cities.

Local Apps That Need Data

Grab — the dominant ride-hailing app in Phnom Penh and Siem Reap. Tuk-tuks and cars are both bookable. Requires mobile data for pricing, booking, and driver tracking.

PassApp — Cambodia's homegrown ride-hailing app, popular with locals and increasingly with budget travelers. Cheaper than Grab for tuk-tuks. Needs data to function.

Google Maps — essential for navigation in both cities and for finding specific temples within the Angkor complex. Download offline maps for the Siem Reap region before you arrive.

WhatsApp / Telegram — the dominant messaging platforms for communication with guesthouses, tour guides, and tuk-tuk drivers. Many Cambodia-based businesses prefer WhatsApp over email.

Maps.me or MAPS.ME — useful for offline maps of rural areas and temple complexes where Google Maps coverage details are thin.

Where PAYG Works in Your Favor

TravelPass is not the cheapest per-GB option in Cambodia — a local SIM gives you more gigabytes per dollar if you actually use them. But PAYG has specific advantages that apply to most Cambodia travelers.

Short trips (three to seven days) rarely exhaust a 10 GB local SIM package, meaning you're paying for data you leave behind. Temple days, overland travel days, and long tuk-tuk rides between sites all consume little data. If three of your seven days are low-data, a flat daily charge or prepaid bundle is wasteful.

Multi-country itineraries benefit most. If you're moving from Thailand to Cambodia to Vietnam, one TravelPass balance covers the whole trip. No SIM swaps at each border, no currency confusion at airport kiosks, no expiring local credits. For onward travel to Malaysia or Indonesia, the same balance continues.

How Much Data Will I Need?

A practical estimate for a five-to-seven day Cambodia trip:

  • Phnom Penh city days (2): ~500 MB/day — Grab pickups, Google Maps, messaging with accommodation = ~1 GB
  • Siem Reap + Angkor days (2–3): ~200–400 MB/day — lighter usage at temples, maps preloaded offline = ~0.6–1.2 GB
  • Transit days (1–2): ~100–200 MB — minimal use during bus/flight travel = ~0.2–0.4 GB
  • Total estimate: 1.8–2.6 GB for a standard trip at $4.58/GB = roughly $8–12

Add more if you plan to video call home daily or work remotely. Subtract if you're staying in hotels with reliable WiFi and using it heavily. The USD economy means most transactions in tourist areas don't require mobile payment apps — one less data drain compared to cashless countries.

Device Compatibility

TravelPass requires an eSIM-compatible device. Most current-generation phones support eSIM: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and many other Android devices. Older budget Android phones often lack eSIM support.

Check the full eSIM compatibility list before purchasing. A physical SIM slot is not required — the eSIM profile is separate from your existing nano-SIM. You can run both simultaneously.

Setup and Installation

Install the eSIM before you arrive in Cambodia — airport and hotel WiFi is not reliable enough to depend on for eSIM installation.

  • Step 1: Create a Bcengi account and add credit
  • Step 2: Install the eSIM profile by scanning the QR code from your confirmation email
  • Step 3: Enable data roaming for the TravelPass line when you land

The eSIM stays installed on your device indefinitely. Your remaining balance carries forward to future trips anywhere TravelPass is available.

Before You Arrive

Cambodia's mobile infrastructure covers the tourist corridor well — Phnom Penh, Siem Reap, Sihanoukville, and the main roads between them. Outside those corridors, expect patchy 3G or no signal. Metfone 4G handles navigation, messaging, and Grab bookings without issue in the cities.

  • Install and test TravelPass before departure — confirm the eSIM profile is active
  • Download Google Maps offline for Phnom Penh, Siem Reap, and the Angkor region
  • Download any entertainment for long bus journeys (Phnom Penh to Siem Reap is 5–6 hours)
  • Rate: $4.58/GB on Metfone — no daily charge, no expiry
  • Manage your account and top up at travel.bcengi.com

Frequently Asked Questions

How much does eSIM data cost in Cambodia?

Bcengi TravelPass charges $4.58/GB on the Metfone network in Cambodia. There is no daily fee and no expiry on your balance. A typical five-day trip uses 2–3 GB, costing roughly $9–14.

Do I need to remove my physical SIM to use a Cambodia eSIM?

No. The TravelPass eSIM runs as a second line alongside your existing SIM. Your home SIM stays active for calls and texts; TravelPass handles mobile data. No SIM swap required.

Can I use eSIM on my iPhone or Android in Cambodia?

Yes, if your device supports eSIM. iPhones from XS onward, Pixel 3+, Galaxy S20+, and most current flagship Android phones are compatible. Check the full compatibility list if unsure.

Does eSIM work everywhere in Cambodia?

Coverage is reliable in Phnom Penh, Siem Reap town, Sihanoukville, and along Route 6 between the major cities. Signal becomes patchy in rural areas, remote temple complexes, and provincial roads. Metfone 4G covers the tourist corridor; expect 3G or no signal outside it.

How much data do I need for a week in Cambodia?

For a typical seven-day Cambodia trip (cities + temples), plan for 2–3 GB. City days with Grab, navigation, and messaging use around 400–600 MB each. Temple days are much lighter — 100–200 MB. Budget $9–14 at $4.58/GB.

Does eSIM work at Angkor Wat?

At Angkor Wat itself and the main temples on the Grand and Small Circuit (Bayon, Ta Prohm, Banteay Kdei), Metfone has usable signal — typically 4G at Angkor Wat, dropping to 3G or patchy at more remote temples. Outer temples like Beng Mealea (60 km from Siem Reap) have very limited or no signal. Download offline maps the night before any temple excursion.

Will I have signal between Phnom Penh and Siem Reap?

Route 6 passes through several provincial towns with Metfone coverage, but there are rural stretches with weak or no signal. Expect interrupted connectivity during the five-to-six hour bus or taxi journey. Streaming is unreliable; download content before you depart.

Is Cambodia always combined with other countries?

Most visitors combine Cambodia with Vietnam, Thailand, or both. The Bcengi TravelPass balance works across all three countries — the same eSIM and remaining credit continues in Vietnam and Thailand at their respective rates, which makes it well-suited for multi-country Southeast Asia itineraries.

Does the eSIM work on Cambodian islands?

Koh Rong and Koh Rong Samloem have basic Metfone coverage near the main beach areas, but it is inconsistent. Smaller, less-developed islands may have no signal at all. Ferry crossings between the mainland and islands are out of range. Plan for limited connectivity on island stays.

Can I use the same eSIM in Vietnam and Thailand?

Yes. The Bcengi TravelPass eSIM works in both countries, along with Cambodia. Your credit balance carries across borders and you are billed at each country's per-GB rate. No new SIM, no additional setup — just enable data roaming when you cross the border.
