Mobile connectivity guide for Cambodia

Cambodia has improving 4G coverage across Phnom Penh, Siem Reap, and the main tourist areas. Metfone provides solid coverage in urban centres and popular tourist zones. For Singaporeans, Cambodia is primarily visited for Angkor Wat and the temples of Siem Reap, which are a major ASEAN bucket-list destination. Phnom Penh's history and riverside culture are also popular. 185+.

eSIM Travel Tips for Cambodia

Angkor Wat is the main reason Singaporeans visit Cambodia
Angkor Wat and the surrounding Angkor Archaeological Park near Siem Reap is one of the world's greatest temple complexes and a major bucket-list item for Singapore travellers. Good 4G coverage throughout the main Angkor Park temple areas and Siem Reap city. Set up your HelloRoam eSIM at home before your Changi departure for hassle-free temple exploring.
PassApp is Cambodia's main ride-hailing app
PassApp is the leading ride-hailing and tuk-tuk booking app in Phnom Penh and Siem Reap. It functions similarly to Grab and is the safest way to arrange transport for Singapore visitors. Your HelloRoam eSIM keeps PassApp running from the moment you arrive at Siem Reap International Airport.
Angkor Wat sunrise: early morning connectivity is important
Sunrise at Angkor Wat (around 5:30am) is one of Cambodia's most magical experiences and popular with Singapore visitors. The main Angkor Wat moat and west gate area have good 4G even at sunrise. Your HelloRoam eSIM keeps your tour guide app, camera apps, and social media running for the most Instagrammable sunrise in Southeast Asia.
Phnom Penh history: S-21 and the Killing Fields
Phnom Penh's Tuol Sleng Genocide Museum (S-21) and the Killing Fields at Choeung Ek are sobering and important historical sites for Singapore visitors learning about Cambodia's recent history. Both sites have 4G coverage. Audio guide apps work well with your HelloRoam eSIM data.
Sihanoukville and island beaches: limited coverage
Sihanoukville and the nearby islands (Koh Rong, Koh Rong Sanloem) are beach destinations growing in popularity with Singaporeans. Coverage in Sihanoukville town is reasonable. Island bungalow areas have very limited or no cellular signal. Download your ferry booking and island accommodation before leaving Sihanoukville pier.

Mobile networks in Cambodia: what Singapore visitors need to know

HelloRoam connects on Metfone in Cambodia. Metfone is Cambodia's leading operator (Viettel-owned) with solid 4G coverage in Phnom Penh, Siem Reap, and along the main tourist corridors. Rural areas and island destinations have limited coverage.

HelloRoam eSIM vs Singtel, StarHub, or M1 Cambodia roaming

Recommended

Typical cost

From $4.00 total

Details

Plans from $4.00. Buy before your Scoot or Cambodia Angkor Air flight from Changi, activate at home, and land in Siem Reap already on local 4G. PassApp and Google Maps ready from the terminal.

Cambodian SIM

Typical cost

$1.00–$5.00 total

Details

Cambodian SIMs are available at airports and markets. A HelloRoam eSIM sorted at home avoids registration and is ready before your Changi flight.

Singtel, StarHub, or M1 Cambodia roaming

Typical cost

$10.00–$15.00/day

Details

Singapore carrier Cambodia roaming packages can cost $5 to $12 per day. A week at Angkor Wat and Phnom Penh on SG roaming adds up significantly compared to a HelloRoam eSIM at $4.

Prices approximate as of April 2026. Actual savings vary.

Best time to visit Cambodia from Singapore

Cambodia's dry season from November to May is the best time to visit. November to February is cool and pleasant at Angkor Wat with lower humidity. March to May gets hot. The wet season from June to October brings rain but the Angkor temples are beautifully lush and green. Singapore school holidays in June and December are peak SG visit times.

What to Know Before You Buy

eSIM requires an unlocked, eSIM-compatible device. Check your phone settings before purchasing.
Most travel eSIM plans provide data only. Your existing phone number stays active for calls and texts on your primary SIM.
Coverage quality varies by location within Cambodia. Urban areas typically have strong 4G/5G coverage, while rural or remote areas may have limited connectivity.
Install your eSIM before departure. Activation requires an internet connection, which may not be available at your destination airport.
