Cambodiaesim.com

Cambodiaesim.com, operated by GIGAGO, a Hong Kong-based travel eSIM provider, is an eSIM service focused on tourists visiting Cambodia. Despite its recent entry into the market, Cambodiaesim.com has carved out a strong position in this niche by specialising exclusively in Cambodia. It offers a wide variety of plans tailored to customers' needs and budgets, with one of the most comprehensive selections of eSIM options suited to the length of your stay and your data requirements.

Holafly

Holafly is another major eSIM provider catering to tourists in Cambodia. With a substantial market share, its products cover a wide range of countries and regions worldwide. Through partnerships with leading local network operators in Cambodia, Holafly provides reliable internet access across most areas, including urban centres, rural regions, and popular tourist destinations. Holafly offers unlimited data plans exclusively, but please note that high-speed data is capped, and speeds may be reduced once you exceed this limit. Also worth noting: Holafly's standard plans for Cambodia are data-only, designed for travellers who rely on messaging apps and data-based calling.

Airalo

Another established eSIM provider, Airalo has been offering eSIMs in over 200 countries and regions since its launch in 2019. They have developed an app that allows customers to purchase, use, and manage their eSIMs with ease. In Cambodia, Airalo primarily uses the Smart network, delivering fast and stable speeds – particularly useful in Phnom Penh, Siem Reap, and Sihanoukville (some plans may also connect to Metfone). Several eSIM plans are offered for Cambodia, but only a limited number are country-specific; the rest cover broader regional zones. For tourists travelling exclusively to Cambodia and not visiting neighbouring countries, this can work out more expensive than necessary.

Nomad

Nomad is a global eSIM service provider catering to short-term travellers, frequent flyers, and those visiting multiple countries on a single trip. To use Nomad's eSIM, simply visit their website, select your destination (Cambodia), and choose the plan that suits you. In Cambodia, Nomad's eSIM connects to the Metfone network (which may connect to other local partners), providing reliable coverage across key destinations. However, like Airalo, Holafly, and many others, Nomad offers data-only eSIM plans without local phone numbers, and its prices may be relatively higher than some competitors for certain plans.

How to Set Up Your Cambodia eSIM in 5 Easy Steps

Getting connected in Cambodia is super easy! Let me show you how to set up your eSIM. I've helped plenty of travellers, and it's honestly simpler than you'd think.

Step 1: Check Your Phone Compatibility

First things first – check if your phone supports eSIM: simply dial *#06# in your phone app. If you see an "EID" number, you're good to go! Also make sure your phone isn't carrier-locked (check with your current UK provider if you're unsure – most UK networks like EE, O2, Vodafone, and Three now support eSIM).

Step 2: Choose Your Plan

Pick the perfect plan on Trip.com, whether it's a 10 GB/7-day plan or a 50 GB/15-day option. Many of Trip.com's Cambodia eSIM plans connect through Metfone, one of the country's leading 4G/5G networks. This gives you reliable coverage across Cambodia, from the temples of Angkor to the beaches of Koh Rong.

Step 3: Get Your QR Code

After purchase, Trip.com will email your QR code within minutes. Top tip: make sure you're in a spot with stable Wi-Fi for the installation – download the QR code before you leave the UK if possible!

Step 4: Install Your eSIM

Go to Settings → Mobile Data → Add Data Plan, then scan the QR code. When you see a welcome message, tap OK. Quick tip: name your eSIM "Cambodia" or "Metfone" so you can easily find it later. Important: only scan the QR code on the device you'll actually be using during your trip!

Step 5: Check Your Connection

Once you land in Cambodia, activate your new eSIM and turn on Data Roaming. To check your data balance, simply dial *1201# – since 2022, this has been the common balance check code for all major Cambodian networks.

Top tip: activate within 60–90 days and reinstall up to 10 times on the same device. Ready to grab these great Cambodia eSIM deals? Let's go!
