Cambodia Travel Prep: Why a Little Planning Goes a Long Way
Navigating Cambodia's unique entry requirements, dual currency system, and connectivity options efficiently means less hassle and more time enjoying your trip.
Stepping into Cambodia, a land rich with history and vibrant culture, is an unforgettable experience. But before you can immerse yourself in the wonders of Angkor Wat or the bustling streets of Phnom Penh, some practical planning is in order. The landscape of travel essentials, from entry requirements to staying connected, evolves, making it crucial to understand your options.
Today, travelers have more choices than ever when preparing for their Cambodian journey. The advent of digital services has streamlined some processes, while local market dynamics offer varied solutions for connectivity and cash. Yet, understanding which path suits you best—and where to seek the most up-to-date information—remains paramount for a smooth arrival and enjoyable stay.
Visa: eVisa or On Arrival? And the New e-Arrival Card
For many nationalities, Cambodia offers a dual-track approach to entry visas: the eVisa and the Visa on Arrival. The eVisa, accessible via the official government website, provides a convenient option, allowing you to secure your travel authorization before you even board your flight. This tourist visa (Type-T) is typically valid for travel within 90 days from its issue date and permits a stay of up to 30 days, with the possibility of extension. Opting for an eVisa can certainly reduce anxieties about queues upon landing.
Alternatively, if you prefer a more traditional approach or find yourself making last-minute plans, the Visa on Arrival option is available at international airports like Siem Reap International Airport. This process usually requires a valid passport, a recent passport photo, and completion of forms distributed at the arrival hall. While often straightforward, wait times can range from 15 to 45 minutes.
However, a significant development for all travelers is the mandatory e-Arrival Card. Regardless of your visa status, this digital form must be completed online within seven days prior to your arrival to expedite entry. This new system aims to simplify immigration, health, and customs declarations, sometimes even incorporating an Electronic Visa On Arrival. It's crucial to check the Cambodia e-Arrival official portal before your trip, as some travelers may find they are no longer required to apply for a separate Tourist Visa (Visa T) or pay fees, only needing to complete this card. We always advise checking the latest requirements with the Royal Embassy of Cambodia or official government immigration websites well in advance of your travel date, as policies can change.
Navigating Cambodia's Dual Currency System
One of the most distinctive aspects of managing finances in Cambodia is its unique dual currency system. The US dollar (USD) and the Cambodian riel (KHR) operate side-by-side, with the USD predominantly used for most transactions and prices, while the riel serves primarily for smaller change. This arrangement stems from a long-standing unofficial fixed exchange rate, hovering around 4,100 KHR to 1 USD since the late 1990s. Today, rates typically reflect around 4,067-4,068 KHR to 1 USD.
This system means you'll likely receive riel when getting change from a dollar payment, especially for smaller amounts. Our view is that carrying a mix of both currencies is the most practical approach. Larger denominations for hotels, tours, and more significant purchases will almost certainly be in USD, while local markets, street food vendors, and small purchases are where riel comes in handy. It’s also worth noting that Cambodian society tends to prefer transactions in USD. Keep small USD bills on hand, as merchants may not always have change for larger notes. Most importantly, ensure your USD bills are crisp and undamaged; torn or excessively worn notes can be rejected.
Staying Connected: The SIM Card Debate

Staying connected in Cambodia is remarkably easy and affordable, with numerous options for tourists. The primary decision revolves around convenience versus cost, and whether you prioritize a local phone number or purely data connectivity.
For immediate connectivity upon arrival, purchasing a local SIM card at the airport is a popular choice, and often the most cost-effective. Providers like Smart Axiata offer their "Smart Traveller SIM" for as little as $5, which often includes a bundle of data. Other major local networks, such as Cellcard and Metfone, also have competitive tourist SIM packages available in arrival areas at international airports like Phnom Penh International. Prices for a SIM with some credit generally range from $5 to $10, with data packages for 30 days costing around $10 for 60GB (Smart) or $20 for 20GB (Metfone). Be prepared to show your passport for registration, which is a standard requirement. While airport vendors are convenient, it's worth noting that street vendors might inflate prices significantly, so official stores are usually a safer bet.
Coverage for these local SIMs is generally strong in major towns and cities, but can vary dramatically outside population centers. Metfone is often cited for its reliable coverage across wider areas, though its speeds might be slightly lower than competitors like Cellcard, which has been recognized for its fast 4G network. If you’re traveling in a group, consider sticking to the same network or relying on apps like WhatsApp for calls and texts, as inter-network communication can be costly.
Alternatively, for those prioritizing convenience above all else, pre-ordering a physical SIM card or an eSIM from international providers is an option. Companies like travSIM and SimCorner offer various data packages delivered to your home before you travel. These often provide reliable 4G/5G data coverage and can be activated prior to arrival, ensuring connectivity the moment you land. However, these options are typically data-only, meaning no local Cambodian phone number for calls or texts, and they can be significantly more expensive than local airport SIMs. We advise travelers to weigh the cost savings and local number benefits of buying upon arrival against the peace of mind offered by pre-arranged international SIMs or eSIMs.
