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.

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.

On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
