Traveling in Cambodia is an amazing experience, but staying connected is important. Whether you need maps to navigate, want to book tours, or simply want to share your adventures with friends and family, having reliable internet will make your trip smoother and more enjoyable.
Here’s everything you need to know about SIM cards and mobile internet while traveling in Cambodia.
Buying a SIM Card in Cambodia
Getting a SIM card in Cambodia is simple and affordable. Here’s a step-by-step guide so you know exactly what to do.
1. Bring Your Passport
All SIM cards in Cambodia must be registered to a person, so you’ll need your passport. The store staff will make a copy and register the SIM for you.
2. Where to Buy a SIM Card
At the Airport
- Most international airports in Cambodia have official provider counters, including Smart, Cellcard, and Metfone.
- You can buy a SIM immediately after landing and start using mobile data right away.
- Staff will help insert and activate your SIM.
Convenience Stores / Minimarts
- Many convenience stores and local minimarts sell SIM cards from Smart, Cellcard, or Metfone.
- Look for packages labeled “tourist SIM” or “data pack”.
- Bring your passport — registration is required, and staff can usually help with activation.
Official Provider Shops (Phone Shops)
- Each provider — Smart, Cellcard, and Metfone — has official stores in towns and cities.
- These shops offer the full range of data plans, from daily packs to monthly packages.
- Staff can help set up your phone, adjust internet settings (APN), and show you how to top up or check your balance.
- Ideal for travelers who want more data, calls, or longer-term usage.
Tip: If you want internet right away, buy at the airport. If you want more options or cheaper packages, wait for a store in town.
3. Pick a Package
Choose a data plan that matches your stay and usage:
- Daily packs: For short trips with small data needs
- Weekly packs: Perfect for tourists staying a few days
- Monthly packs: Ideal for long-term visitors or heavy internet users
Tourist SIM cards usually cost $2–5 USD for 1–3 GB of data. Some plans also include local calls or texts.
4. Activation
The shop staff will usually help you insert the SIM and activate it. Before leaving, check:
- Mobile data is working
- You can make calls if included
- The correct data package is active
Some phones may require adjusting the APN (internet settings), but the staff can assist.
5. Top Up Your SIM
If you run out of data, you can refill your SIM:
- At convenience stores or provider shops
- Online via the provider’s website or app
- Using mobile credit cards sold in stores
Pro Tip: Ask the staff to show you how to check your balance and top up — it saves time and avoids surprises later.
Internet Options
- Mobile Data: Works well in cities, towns, and tourist areas. Coverage can be weaker in rural locations.
- Wi-Fi: Most hostels, cafes, and restaurants provide free Wi-Fi, usually reliable for browsing, chatting, or streaming.
- Data Packages: Top up daily, weekly, or monthly depending on your stay and internet needs.
Tips for Staying Connected
- Check Coverage: Ask about network availability if you plan to visit rural areas.
- Use Wi-Fi Whenever Possible: Save your mobile data for essential tasks.
- Download Maps Offline: Google Maps or Maps.me work without data.
- Keep Your SIM Active: Some providers deactivate SIM cards if not used for several days.
