Coverage
Coverage reality in Cambodia
Cambodia runs on 3 major mobile networks — Cellcard, Smart Axiata, and Metfone — with 4G LTE as the top available standard. Measured download speeds average 20 Mbps, placing Cambodia in the mid-range performance bracket. 5G has not launched commercially in Cambodia. Connections top out at 4G LTE on all available networks. Cellcard provides the widest geographic reach, with Smart Axiata offering competitive coverage in urban centres. Travel eSIMs from HelloRoam and Airalo both partner with Cellcard as the primary network for Cambodia plans. Our top-rated pick connects to Cellcard for Cambodia plans, delivering the same network quality as a local prepaid SIM at a fraction of the setup friction.

Comparison
Provider fit for Cambodia
HelloRoam — our top-rated pick — routes Cambodia plans through Cellcard, the highest-coverage Tier-1 network in the country, delivering 4G LTE at $1.44/GB. Airalo offers Cambodia plans through both Cellcard and Smart Axiata, making it the stronger choice when network redundancy matters — particularly in rural areas where Cellcard coverage thins. Holafly covers Cambodia with unlimited daily plans from $3.66/day. It is the correct pick for travelers streaming video, taking video calls, or tethering a laptop — scenarios where a fixed data cap creates daily anxiety. Saily adds VPN protection from NordVPN's parent company, useful for travelers who prioritise privacy on public WiFi in Cambodia. Nomad offers the lowest absolute prices in select Asian destinations and can undercut HelloRoam's per-GB rate in a small number of markets.

Is an eSIM better than buying a local SIM at the airport in Cambodia?

Local SIMs can offer better pricing in some destinations but require in-person purchase and registration.
Can I use an eSIM and my regular SIM at the same time in Cambodia?
Yes. Most modern phones support dual SIM operation with one physical SIM and one eSIM active simultaneously in Cambodia. Your home SIM keeps your regular phone number for calls and texts.

What happens if my eSIM data runs out in Cambodia?
HelloRoam and Airalo both support in-app top-ups that activate within minutes if you exhaust your plan in Cambodia. Purchase additional data through the provider’s app without buying a new eSIM or swapping a SIM card. Alternatively, purchase and install a second eSIM plan alongside the first. Holafly unlimited plans renew each day automatically.
