Phnom Penh International Airport, Phnom Penh

When arriving, be prepared for a new immigration system with tablets for filling in information, which is quicker than paperwork.

Getting a SIM card at the airport is convenient and a good deal; expect to pay around $7 for 60 GB.

Expect to negotiate a bit with tuk-tuk drivers; they may try to charge extra, but it's common practice.

Be prepared to pay for services in either USD or Cambodian Riel; the exchange rate is about 4,000 Riel to a dollar.

Consider getting a cab right after you leave the airport for a straightforward journey into the city.

It's about 10 km from the city center, and it takes around 30 minutes to get there by cab.

If you need a SIM card, there's a place right outside the airport where you can buy one, and it's quick to set up.
