First 24 Hours in Cambodia
Your step-by-step guide from pre-departure to settling in. Follow these steps and you'll hit the ground running.
Submit Your e-Arrival Form
Since January 2025, all air arrivals must submit the e-Arrival card online. Do this before you board your flight.
- Go to arrival.gov.kh
- Fill in immigration, health, and customs declarations
- Save or screenshot the QR code you receive
- It's free — no payment required
Get Through Immigration
At immigration, you'll go to either the e-Visa lane (if you applied online) or the Visa on Arrival counter.
Visa on Arrival: Have ready:
- Passport (6+ months validity)
- One passport photo
- $30 USD cash (exact change preferred)
- Your e-Arrival QR code
e-Visa holders: Go directly to the immigration counters with your printed/digital e-visa approval.
The whole process typically takes 15-30 minutes.
Get a SIM Card
Immediately after exiting immigration, look for the mobile carrier booths in the arrivals hall — they're in both Techo International Airport (Phnom Penh) and Siem Reap–Angkor International Airport.
Recommended: Smart Traveller SIM — $5 for 30GB/15 days with calls.
You'll need your passport for registration. The staff will set it up for you in about 5 minutes.
This is critical — you need a local number to register for PassApp (Cambodia's cheapest ride-hailing app).
Get Your Cash Sorted
Cambodia's national currency is the Cambodian riel (KHR), and the US dollar is an official secondary currency. You can pay in either — but riel is the one accepted everywhere, without exception.
- Bring small USD bills ($1, $5, $10) from home if possible, then withdraw riel once you land
- There are ATMs at the airport. Fees run $5-10 per withdrawal whichever bank you pick — Canadia and ACLEDA charge a flat $5, while BRED charges more but lets you take out $2,000 at once instead of $1,000
- Exchange counters are available but rates are slightly worse than in the city
- You'll pick up riel automatically as change — but it's worth withdrawing some deliberately too, since it's accepted everywhere and dollars aren't
Download Essential Apps
With your new SIM card working, download these apps:
- PassApp — Ride-hailing (cheapest option). Register with your new Cambodian number
- Grab — Backup ride-hailing (works with international number)
- Google Maps — Navigation (works well in Cambodia, download offline maps)
- Bakong Tourists — QR code payments at 4.5M+ merchants (link your Visa/Mastercard)
- Telegram — Cambodia's #1 messaging app (not WhatsApp)
Pro tip: Download offline Google Maps for "Cambodia" before you leave WiFi range. Cell data can be spotty in some areas.
Get to Your Hotel
Now that you have PassApp installed:
From Techo International Airport (KTI) to Phnom Penh:
- PassApp/Grab: $10-20 depending on your neighbourhood
- Airport taxi counter: $17-30 (fixed price)
- Allow 45-60 minutes — Techo is ~20 km south of the city
Note: Phnom Penh's airport changed in September 2025. Techo replaced the old Phnom Penh International Airport, which sat much closer to town. If your hotel quotes you an old $9-12 transfer price, it's quoting for an airport that no longer takes flights.
From Siem Reap→Angkor International Airport (SAI) to Town:
- PassApp/Grab: $10-15
- Note: The airport is 45km from town (farther than the old one)
Tip: If PassApp hasn't activated yet, use Grab (works with your international number) or the airport taxi counter for your first ride.
Settle In & Explore
You're set! A few final tips for your first evening:
- Eat local: Try Bai Sach Chrouk (grilled pork rice, ~$1.50) or Kuy Teav (noodle soup, ~$1)
- Stay hydrated: Buy bottled water ($0.25-0.50) — never drink tap water
- Keep safe: Wear bags on the side away from the road (bag snatching happens)
- Tipping: Not expected but appreciated. Round up or leave $1 at restaurants
- Electrical outlets: Cambodia uses Type A, C, and G plugs. Voltage is 230V. Bring a universal adapter
