Grab is the best first app for most visitors to Cambodia. PassApp is a useful local backup for tuk-tuks and cars, but you'll need to test its SMS registration and payment flow before depending on it.
Set up Grab before arrival, add PassApp only if you can verify the phone number, and carry small Cambodian riel. At Techo International Airport, use an official taxi counter or a trusted ride-hailing app and follow the current pickup instructions. For any journey near the Thailand border, check official advice before checking app supply.
| Situation | Best approach |
|---|---|
| First ride or foreign card | Start with Grab and compare the car and tuk-tuk products shown at the exact pickup.51 |
| Short city ride in a PassApp market | Compare PassApp after confirming that SMS login and payment work.26 |
| Arrival at Techo International Airport | Use the airport's official taxi counter or book Grab or PassApp in the app, then follow the current pickup instructions.7 |
| Luggage, late arrival or an exposed pickup | Prefer an enclosed car, keep belongings away from the road side and share the trip details.3 |
The easiest all-round ride app for upfront car, tuk-tuk and other live options across many Cambodian cities.
Cambodia's major local ride app for tuk-tuks, rickshaws and cars in Phnom Penh and several tourist cities.
| At a glance | Grab | PassApp |
|---|---|---|
| Signing up | Verify a mobile number before arrival and keep access to it. GrabLite can load on a weak connection, but it removes chat and several normal safety and payment features. | An active mobile number is required. A Cambodian SIM is the practical fallback if a foreign number does not receive the verification code. |
| Paying | Cambodian Grab terms permit cash, card and any other method shown in the app. Confirm the selected method before requesting. | PassApp's current public listing does not promise foreign-card acceptance. Treat cash in Cambodian riel as the safe default unless checkout explicitly shows another working method. |
| English | The rider flow is available in English, including pickup instructions and in-app chat when the normal app is online. | The app listing and core booking flow are available in English; drivers may communicate in Khmer. |
| Where it works | Grab's current directory lists 21 Cambodian markets, with cars, tuk-tuks and taxis varying by location and live supply. | The current listing names Phnom Penh, Siem Reap, Battambang, Sihanoukville, Kampot, Poipet and Kampong Cham, with tuk-tuk, rickshaw, cab and SUV options varying live. |
Not available here Uber does not list Cambodia among its current operating countries. Use Grab or PassApp instead, and compare the live pickup point, vehicle type and total before booking.
Grab's directory listed 21 Cambodian locations when checked in August 2026, reaching well beyond Phnom Penh and Siem Reap. Vehicle menus still differ by market. Enter the real pickup and destination before deciding whether a car, tuk-tuk, remorque or taxi is genuinely available for that trip.45
Cash and cards are both supported under the Cambodian terms, but only the method displayed and selected in the live booking applies. Keep enough riel for a cash ride and do not let a driver move the trip or its payment outside Grab.1
GrabLite can keep the app usable on a poor connection, but the fallback is cash-only and removes chat, arrival estimates, number masking and some map behavior. It is useful for recovery, not equal to a normal booking. Screenshot the destination in Khmer and keep the booking active until the ride is complete.1
PassApp's current store listing names seven cities and offers tuk-tuks, rickshaws, cabs and SUVs. It requires an active mobile number. Recent verified reviews include failures to receive an SMS on foreign numbers, so registration should happen before an airport arrival or early departure.26
The current public listing does not clearly promise international-card or KHQR payment for the passenger app. Unless the live checkout proves otherwise, prepare the exact cash fare in riel and ask support inside the official app about a disputed charge.2
Techo International Airport lists standard taxis plus Grab, WowNow and PassApp as app-based taxi options. It gives an approximate airport-to-city fare of US$10 to US$20, while warning that the total can vary with traffic and destination. Use the official taxi counter or complete the booking in a trusted app, then follow the current pickup instructions. Do not treat a driver who approaches you in arrivals as either an official-counter booking or a confirmed app ride.7
Current official advice warns against travel in specified areas within 50 kilometers of the Thailand border because of armed conflict and landmines, and reports that land crossings are closed. Several app directories still name western or border markets. Check government advice first and do not use an available vehicle as evidence that the route is safe or open.3
Phone and bag snatching from open tuk-tuks and rickshaws is also reported. Keep bags on the side away from traffic, use a vehicle with a barrier where available, and prefer an enclosed car for luggage or late arrivals. Avoid long road journeys at night because road deaths are common.3
Hotel names and map pins can point to the wrong gate. Put the pin at the actual entrance, add a landmark, retain the booking screen and compare the plate or vehicle details before boarding. If the assigned vehicle changes without an in-app update, do not enter it.
If neither app can assign a car, ask the accommodation or airport desk for a licensed taxi and agree the complete fare before departure. Keep the destination in Khmer and enough small riel to avoid a change dispute.73
Yes. Grab's current directory lists 21 Cambodian locations, but the exact vehicle types and number of available drivers depend on the pickup point and time.
Grab is the simplest visitor default because it clearly supports cash and cards and publishes broader coverage. PassApp is a useful local comparison for tuk-tuks and cars in seven listed cities, but registration and payment are less predictable for foreign visitors.
Yes. Book only after collecting your luggage, verify the assigned driver and vehicle in the app, and ignore unsolicited offers in arrivals.
No. Do not use a ride app to test access to the Thai frontier. Government warnings report conflict, mines and closed land crossings; those warnings outrank an available vehicle or map pin.
