1. Social Media in Cambodia

Cambodia’s digital landscape has experienced explosive growth in recent years, placing social media at the heart of daily life for both locals and expatriates.

Facebook overwhelmingly dominates the scene; it has evolved far beyond a simple communication tool and has become a key platform for news, commerce, and social connections.

TikTok is especially popular among the younger generation, while Telegram is gaining traction due to its group chat features and a growing sense of enhanced privacy.

Instagram remains a favorite for visual storytelling and image sharing, particularly among young urban Cambodians and micro-influencers.

Facebook groups play a central role in the lives of both expatriates and local communities. They serve as essential hubs for practical daily exchanges: job searches, housing tips, service recommendations, and more. Many newcomers rely on these groups to integrate quickly and get advice tailored to the local context.

However, this popularity also comes with risks.

With the surge in user numbers, attempts at scams and the spread of misinformation have increased significantly. It is therefore crucial to adopt strong security practices, starting with strict management of privacy settings: limit the visibility of your posts, control who can send you messages or friend requests, and activate two-factor authentication on your main accounts.

Developing a critical mindset is equally important when dealing with the flood of information circulating, especially on Facebook and Telegram, where rumors, too-good-to-be-true offers, and unverified news are common. Following official pages, reputable media outlets, or moderated groups is generally a good habit to develop.

Lastly, it’s advisable to regularly consult safety guides and scam alerts shared by expatriate communities and embassies, or to share your own experiences to help others avoid common traps. Social media in Cambodia is an incredible tool for connection and discovery—as long as you adopt the right habits to navigate it safely!

Two Cambodian Social Media Apps to Discover in 2025

1. CoolApp: The Local “Signal-like” Messaging App

Launch & Downloads
Since its launch in July 2024, CoolApp has reached nearly half a million downloads on iOS, Android, and desktop platforms—a fast start for a nationally-focused application.

Main Features
Described as a local alternative to WhatsApp or Telegram, CoolApp offers chat, voice and video calls with end-to-end encryption. The app is built on an independent fork of Signal and is hosted on Cambodia’s DIX network, ensuring fast connections even in low-bandwidth areas.

Security & Criticism
The developers claim that no sensitive user data is stored or accessible. However, experts and organizations like the EFF remain cautious, highlighting the lack of transparent technical documentation and independent audits of its encryption protocols.

International Availability?
CoolApp is officially available on the App Store and Google Play in multiple countries, including outside Cambodia, such as Canada and the United States. There are no official restrictions requiring a Cambodian mobile number to register. However, some foreign users have reported difficulties connecting from the U.S., though these seem to be technical issues rather than deliberate number-based blocking.

2. Snapkyu: A Social Network Focused on Local Content

Launch & Audience
Launched in late 2023, Snapkyu has gathered tens of thousands of users, with its iOS version updated to 1.0.59 in March 2025.

Main Features
Snapkyu is a social network that allows users to post photos, videos, and share updates on a personal newsfeed. It also includes a local marketplace, voice-to-text support in both Khmer and English, and discovery features for local brands.

Compatibility & Stability
The app is available for iOS (from iOS 14 onwards) and Android (from Android 7+). It holds an average rating of around 4.2/5. Some international users, particularly from the U.S., have reported registration issues when trying to sign up using a phone number or Apple/Google ID not linked to Cambodia.

Use by Foreigners
While Snapkyu is visible on international app stores, some users (notably from California) have encountered sign-up errors, possibly due to not having a Cambodian phone number or certain geo-restrictions. There are no official statements indicating the app is restricted to Cambodian numbers, but user experience suggests that having a local number might sometimes be necessary to avoid registration hiccups.

📱 Mobile Networks in Cambodia: A Complete Guide to Choosing and Securing Your Communications (2025)

1. Choosing a Mobile Operator and SIM Card in Cambodia

Cambodia’s mobile network is relatively well-developed, supported by three main operators: Cellcard (Mobitel), Smart Axiata, and Metfone. Each of them has strengths depending on usage, location, and the expectations of foreign visitors.

Cellcard (Mobitel)
Cellcard is the historic operator, very popular among locals. It provides reliable 4G+ coverage, particularly in rural areas. Its main advantages include solid voice and data packages and responsive customer service in both English and Khmer. However, its unlimited data plans are sometimes slightly more expensive compared to its competitors.

Smart Axiata
Smart is the most innovative when it comes to digital services, offering competitive data plans and eSIM options. It has excellent urban coverage in Phnom Penh, Siem Reap, and Sihanoukville. Their data packages are very affordable, and the SmartNas app makes it easy to manage your plan. On the downside, its rural coverage is slightly weaker than Cellcard's.

Metfone
Owned by Viettel Group (Vietnam), Metfone is known for its low prices. It offers very good nationwide coverage and a solid voice infrastructure. Its main advantages are competitive international call rates (to Vietnam, Thailand, etc.). However, its digital services (apps, account management) are sometimes less user-friendly.

Which Operator Has the Best Network Coverage in Cambodia?

According to recent reports (Opensignal, 2025), Smart Axiata is often regarded as the operator offering the best overall user experience. If you're planning to stay mostly in major cities like Phnom Penh, Siem Reap, or Sihanoukville, Smart is an excellent choice, with stable and fast connections ideal for internet browsing, video calls, and social media.

If you plan to venture into more rural areas, such as remote villages or the Angkor temples, Metfone is recognized for its extensive network coverage across Cambodia. It provides the most reliable signal outside urban areas, supported by a vast network of relay antennas and infrastructure inherited from Viettel (Vietnam).

Cellcard offers very good coverage in both urban and semi-rural areas. It stands out for its mobile download speeds, making it a great choice for those who prioritize streaming videos, using social networks, or making video calls.

Which Mobile Plan is Best for Tourists?

If you're visiting Cambodia for a short stay, the simplest solution is to purchase a “Tourist SIM” offered by all three major operators. These prepaid visitor SIM cards are very affordable.

Smart Axiata offers a tourist SIM with around 30 GB of mobile data for $5, valid for 7 to 30 days. This plan also includes unlimited calls to Cambodian numbers. It's perfect for those who need fast internet access for navigation apps or to stay connected via WhatsApp, Telegram, or Messenger.

Cellcard has a similar offer, with visitor packages providing comparable data volumes (around 30 GB for $5 to $6). These plans are popular among European and Asian tourists because they strike a good balance between speed and price.

If you're planning to explore Cambodia off the beaten path, it's worth considering Metfone's packages. While Metfone may offer slightly lower speeds in cities compared to Smart or Cellcard, it remains extremely reliable for rural connectivity. Metfone also offers very competitive prices, with combo plans starting from $1 that include voice, SMS, and data, although the data volume is usually more limited than Smart or Cellcard.

Where to Buy a SIM Card and How Does It Work?

Buying a SIM card in Cambodia is very straightforward. Upon arrival at Phnom Penh or Siem Reap International Airports, you'll find official booths for all three operators where you can purchase a SIM directly. Be aware, though, that prices at the airport may be slightly higher than in the city.

You can also go to the official stores of the operators or to numerous small mobile phone kiosks throughout the cities. Purchasing a SIM card requires presenting your passport for official registration. This procedure is mandatory to comply with KYC (Know Your Customer) regulations. Once purchased, the SIM card is usually activated on the spot within a few minutes.

To recharge your plan later, you can buy scratch cards available at almost every convenience store or recharge directly through local apps like ABA Bank, Wing Money, or through the official operator apps (SmartNas, Cellcard App).

Communication Security: Stay Alert for Scams

As in many Southeast Asian countries, Cambodia is not immune to scam attempts via SMS or phone calls. It’s common to receive suspicious messages claiming you’ve won a prize or urging you to click on malicious links. It’s crucial to never click on these links and always verify the identity of unknown callers.

You can use apps like Truecaller to identify suspicious numbers. If you receive unwanted or dubious calls, it’s easy to block these numbers directly through your phone settings or via operator apps, which sometimes offer call-filtering services.

Essential Apps for Communication and Daily Life in Cambodia

When it comes to messaging, Telegram is extremely popular among Cambodians and is widely used in professional, social, and community circles. WhatsApp remains the top choice for international communications.

Among local apps, ABA Mobile Banking is a must-have if you want to manage your finances, pay with QR codes in stores, or transfer money. Wing Money is also widely used for micro-transactions and daily payments.

If you want to stay informed about official communications, the WinWin Messenger app, developed by the Cambodian government, is the primary tool for receiving alerts and public information.

Conclusion

For tourists, Smart Axiata is often the most balanced option if you’re staying in urban or tourist areas, while Metfone will be the strategic choice if you’re planning to visit rural regions. Cellcard offers excellent data speeds at competitive prices, making it a popular option for visitors who consume a lot of mobile data. Buying a local SIM card is quick and inexpensive, and with a few security precautions, you’ll be fully equipped to stay connected throughout your stay.

📲 Practical Guide: How to Buy and Activate a Cambodia eSIM from the US or UK (2025)

With the widespread adoption of eSIM-compatible smartphones (iPhone, Samsung, Pixel, etc.), it is now possible to secure a Cambodian mobile connection before even landing in Phnom Penh or Siem Reap. This is the ideal solution to avoid wasting time searching for a local SIM card at the airport or in stores.

1. Check if Your Phone is eSIM Compatible

Before anything else, make sure your smartphone supports eSIM technology.

• If you have an iPhone XS or newer, you're good to go.

• For Android users, check if your Samsung Galaxy, Google Pixel, or other models support eSIM (this is usually specified in the network settings).

2. Choose a Reliable Cambodia eSIM Provider

From the US or UK, you have two main options to buy a Cambodia eSIM:

• Buy directly from a Cambodian local operator (Smart, Cellcard, Metfone) if they offer eSIM sales online.

• Use an international eSIM retailer like Airalo, Holafly, Nomad, or esim.net.

Platforms like Airalo or Holafly offer Cambodia-specific eSIM plans or regional plans for Southeast Asia. These eSIMs are easy to install and can be activated within minutes.

3. Choose the Right Plan for Your Stay

If you're staying in Cambodia for a short trip (1 to 2 weeks), you can opt for an eSIM plan offering 5 to 10 GB of data, usually valid for 15 days. These plans typically cost between $8 and $15, depending on the data volume.

If you need unlimited or larger data allowances (20 to 30 GB), more premium plans are available, priced around $20 to $25.

eSIMs from Airalo or Holafly generally operate on Smart or Cellcard's local networks, ensuring reliable connectivity in cities and tourist areas.

4. How to Purchase an eSIM from the US or UK

Here’s the process:

1. Go to the website of your chosen eSIM provider (e.g., Airalo.com, Holafly.com).

2. Search for Cambodia or select a “Southeast Asia” regional plan if you're visiting multiple countries.

3. Select the data volume and validity that match your trip.

4. Complete the payment (credit card, PayPal).

5. Once purchased, you'll immediately receive an activation QR code via email or in your user account.

5. eSIM Installation and Activation

After receiving the QR code:

• Open your phone’s Settings.

• Navigate to Mobile Network / SIM Cards / Add eSIM.

• Scan the QR code provided by the retailer.

• Once scanned, the eSIM will install automatically and be ready to activate.

• Only activate the line when you arrive in Cambodia, or when you're ready to start using mobile data (depending on your plan's terms).

⚠️ Pro Tip: Activate your eSIM only when you’re certain to start using the data, as some packages begin counting from the first network connection.

6. Benefits of Using an eSIM for Your Cambodia Trip

• No need to look for local SIM shops or wait in line at the airport.

• You're connected as soon as you land, which is convenient for booking a Grab ride, finding your hotel, or checking Google Maps.

• You can keep your US or UK number active on your physical SIM to receive bank SMS alerts or important calls.

• Easy and paperless setup.

7. Things to Be Aware Of

Most tourist eSIMs purchased through international platforms (Airalo, Holafly) are data-only and do not include local calls or SMS.

If you need a local Cambodian phone number (useful for certain apps or services), it's better to visit a store once you're in Cambodia and request an official eSIM from Smart or Cellcard that includes voice/SMS packages.

Conclusion

If you want to travel light and stay connected hassle-free, buying a Cambodia eSIM before your departure is the fastest and simplest solution. For a typical 1 to 2-week trip, a 5 to 10 GB eSIM from Airalo or Holafly will be more than enough. However, if you need a local Cambodian number or plan to make local calls, you should consider getting a local eSIM in-store after arrival

📋 FAQ – Mobile Phones and Internet in Cambodia

1. What types of mobile phones work in Cambodia?

2. Can I keep my US/UK number while using a Cambodian SIM card?

3. Are there no-contract unlimited mobile plans in Cambodia?

Operators like Smart, Cellcard, and Metfone offer no-contract plans, with unlimited data packages for certain apps (YouTube, Facebook). Truly unlimited data plans are rare and typically valid only for a limited time (e.g., 1 or 7 days).

4. How do I buy a prepaid SIM card in Cambodia?

You can purchase a prepaid SIM card at official operator stores, mobile kiosks, or at the airport. A valid ID (passport) is required for registration. These SIMs allow you to make calls, send SMS, and surf the mobile internet immediately after activation.

5. How does roaming with my US/UK plan work in Cambodia?

Roaming with US/UK carriers is often very expensive for Cambodia. It’s highly recommended to use a local prepaid SIM or a Cambodia eSIM for affordable mobile data access. Always check roaming rates with your carrier or through your country’s telecom authority.

6. How do I top up my local SIM card?

You can top up via scratch cards available in convenience stores, through operator apps, or by using a credit card on their websites. Local apps like ABA Mobile or Wing Money also make it easy to reload your balance.

8. Can I use my Windows Phone in Cambodia?

Technically, yes—if your Windows Phone supports local GSM bands. However, some local mobile management apps may not be available for Windows OS. An Android or iOS device is generally recommended for compatibility.

11. How can I access the internet in Cambodia if I don’t have a local SIM?

If you haven’t yet purchased a local SIM, you can connect via public Wi-Fi (cafés, hotels, malls). However, for security, it’s recommended to use a VPN on public networks. You can also use your phone as a hotspot if you have an active international SIM or eSIM.

12. What’s the difference between a “mobile phone” and a “cell phone” in Cambodia?

The terms “mobile phone” and “cell phone” are used interchangeably. Any unlocked GSM phone will work with Cambodian networks.

14. Can I use my US/UK SIM card to make calls while in Cambodia?

Yes, but roaming fees are very high. It's better to purchase an international SIM card or a local Cambodian SIM for calls while you're in Cambodia. Alternatively, use VoIP apps (WhatsApp, Telegram, etc.) for cheaper communication.

Once your SIM is activated, you can receive both local and international calls without any issues. Call quality will depend on your operator and network conditions.

17. How do I call landlines or mobiles in the US/UK from Cambodia?

You can use international phone cards or purchase IDD Passes from your Cambodian operator. However, using VoIP apps like WhatsApp or Messenger over data is typically much cheaper.

18. What’s the difference between an international SIM and a local SIM card?

An international SIM card works across multiple countries (including Cambodia), but data and call rates are usually more expensive than a local SIM. A local Cambodian SIM is much cheaper but only functions within Cambodia.

19. Can I keep my US/UK number through number portability?

No, number portability from the US/UK does not apply in Cambodia. However, you can keep your US/UK number active via dual SIM (physical SIM + eSIM) for receiving SMS and calls via roaming.

20. What should I do if my phone asks for a PIN code after inserting a Cambodian SIM?

If your phone asks for a PIN code after inserting the Cambodian SIM card, use the PIN provided with the SIM (usually printed on the SIM card packaging). If you don’t have it, visit an operator store to reset the code.
