Cambodia SIM Card for Tourists: Prices & Where to Buy

Smart’s Traveller SIM is a strong starting point for a Cambodia trip lasting up to two weeks: its published plan fee buys a generous data allowance and calls. Cellcard offers dedicated packages for different stay lengths, while Metfone is another operator to consider once a shop provides a clear starter quote.

Buy a local SIM if you need a Cambodian number or substantial data at a low package price. Roafly suits an unlocked, eSIM-compatible phone when you want to arrange data before departure and do not need conventional calls or SMS.

Cambodia Tourist SIM Prices at a Glance

Compare the allowance and expiry date alongside the price. The cheapest-looking weekly bundle may be a subscription for an existing number, rather than everything a new visitor needs to get connected.

Smart and Cellcard package fees checked on September 28, 2026. Prices and terms may change. These fees are not independently verified all-inclusive counter totals; an undisclosed charge has not been treated as zero.

“On-net” means calls or messages to the same operator. That distinction matters if you plan to call hotels or drivers: a large on-net allowance may not cover the number you actually need.

Before paying, have the seller separate the SIM or number price, chosen package, any activation charge and any mandatory first top-up. Compare that total with the offer you intended to buy.

Smart, Cellcard or Metfone?

Smart: a useful benchmark for a shorter holiday

The Smart Traveller SIM is worth checking first for a trip of up to 15 days. Its combination of data and calling allowances makes it a practical local alternative to a data-only travel plan.

Smart advertises the package through its booths at Cambodia’s international airports. The allowance is generous for everyday navigation and messaging, but its expiry date still matters: unused data does not make a 15-day package cover a month.

Ask which international destinations qualify for the included minutes if you intend to use them.

Cellcard: dedicated packages for different stay lengths

Cellcard’s Traveller range gives visitors clearly defined short-stay and month-long options. The longer package in the table can suit someone who prefers one allowance covering a full month.

Its included calls and texts are on-net. Treat these as a specific benefit for contacting other Cellcard numbers, rather than a general calling allowance for every Cambodian business.

Cellcard also sells ordinary prepaid bundles with different allowances. Those are worth discussing for a longer stay, but the bundle fee alone does not establish the cost of opening a new line.

Metfone: get the complete offer before comparing

Metfone belongs on the shortlist, but a reliably verified tourist starter price was not available for this comparison. An old online price or a cheap recharge advertised for an existing customer is not enough to calculate a new visitor’s bill.

Request three details together:

• The price of a new SIM registered in your name.

• The included data, expiry date and any calls.

• The complete payment required to start using it.

Network choice also depends on where you will spend time. If your accommodation is outside a main town, ask about reception at that specific property and compare the operator’s coverage information. No network name alone establishes reliable service throughout an entire itinerary.

Where to Buy a SIM Card in Cambodia

Airport counters

Airport buying is convenient if you want staff to register and set up the line before continuing to your hotel. Smart’s current shop directory includes Techo International Airport, serving Phnom Penh.

Use the dedicated guide to buying a SIM at Techo Airport for the airport-specific options. Keep the distinction between a national package tariff and the counter’s quoted total.

Do not assume the airport is more expensive—or that a city shop is cheaper—without comparing the same package and all initial charges.

Operator stores and service points

City stores are useful when you want to discuss a longer stay, compare a tourist package with standard prepaid service, or get help with your phone.

Cellcard offers physical SIMs through its official stores and service points. Use clearly identified operator outlets and ask staff to complete registration under your own identity.

Bring your phone and passport. Before starting the registration process, ask which payment methods the outlet accepts; do not rely on every counter accepting an overseas bank card.

Buying a local eSIM online

Local service does not necessarily require a plastic SIM. Smart supports eSIM purchases through SmartNas, its website and shops.

Its app purchase process includes selecting a number and plan, scanning a passport or national ID, and completing a face scan. You need a compatible phone and Wi-Fi during setup.

The useful distinction is therefore between local mobile service and a travel data plan, as well as between physical SIM and eSIM. Going digital does not automatically remove local identity checks.

Passport Registration and Activation

Cambodian operators must verify valid identification before activating service. Cellcard accepts a valid passport for registration, and Smart also supports passport-based verification.

Take your passport to the shop and register the number in your own name. Decline a SIM already registered to somebody else.

Before leaving the counter:

1. Match the package to your trip. Have staff show its data allowance and expiry date.

2. Understand renewal. Ask whether the package renews automatically and what balance it would use.

3. Test mobile data. Turn off Wi-Fi, select the new SIM for data and open a webpage.

4. Test calls if you need them. Check which destinations or networks the allowance covers.

5. Keep the receipt and SIM carrier. They can help identify your purchase if support is needed.

Your phone must be carrier-unlocked to use another operator’s SIM. If replacing your home SIM, store it securely; dual-SIM arrangements depend on the particular device.

Local SIM or Roafly eSIM?

Local packages make sense when a Cambodian number, conventional calls or a large allowance matters most. Roafly is useful when you want to set up mobile data before departure and avoid arranging a new local line at a shop.

Roafly’s 5 GB package costs US$11 and its 10 GB package costs US$18, both valid for 30 days. These standard prices were confirmed on September 28, 2026 and may change.

The Cambodia eSIM lists Metfone and Cellcard as supported networks. It provides data only, with no Cambodian phone number, conventional calls or SMS.

Its practical features include:

• Installation before travel on a compatible, unlocked device.

• No identity verification for the current Cambodia product.

• Hotspot use within the purchased allowance, without a separate hotspot quota.

• Top-ups when you need more data.

Your existing messaging apps can use the data connection. Keep your home line’s data roaming disabled unless you intentionally want to use your carrier’s overseas service; retaining your usual number does not make its roaming activity free.

Roafly’s main appeal here is arranging a data-only travel package without the local number-selection and registration process. For a wider comparison of digital plans, explore the best eSIM options for Cambodia.

Which Option Fits Your Trip?

• Up to two weeks, with a Cambodian number: Start by comparing Smart’s Traveller package with the full price quoted at purchase.

• A month with local calls: Consider Cellcard’s longer Traveller package and compare eligible standard prepaid alternatives.

• Data arranged before departure: Roafly suits navigation, messaging and other internet use when you do not need a local number.

• An existing preference for Metfone: Get a current starter quote and match it to your destinations before paying.

• A phone without eSIM support: Buy a registered physical SIM, provided the phone is unlocked.

FAQs

Will a Cambodian SIM package also work in Vietnam or Thailand?

Do not treat a Cambodian domestic data allowance as regional roaming. Before an onward trip, obtain the roaming terms for your exact package or arrange separate service for the next country. Roafly’s Cambodia plan covers Cambodia.

Can I keep my existing WhatsApp number?

Yes. You can continue using an already configured WhatsApp account over your new data connection without changing its registered number. Retain access to your original number in case WhatsApp later needs to verify it again.

Should I buy a separate SIM for everyone in my group?

Separate connections are more practical if you may split up. Sharing one phone’s hotspot can work while you stay together, but the other devices depend on that phone’s battery, signal and proximity.

Local SIMs are the stronger fit for a Cambodian number and potentially lower data costs. Roafly is a practical choice when pre-departure setup and a straightforward data package matter more. Compare the complete price, validity and registration process before deciding.

Roafly publishes this guide and sells the travel eSIM discussed above.
