Using your eSIM in Cambodia
According to the plan details the eSIM connects to Cellcard and Metfone, and the phone picks whichever is strongest where you are standing. A mix: 7 plans list 5G, 7 are 4G only. The table above does not show speed, the app does.
Sizes run from 500 MB over 1 day at $3.89 to 50 GB over 180 days at $92.25. Every plan here can be topped up from the app without reinstalling anything.
Practical notes for Cambodia
- Coverage is good in Phnom Penh, Siem Reap, Kampot and the coast; rural provinces are thinner.
- Grab and PassApp are the ride-hailing apps and are far cheaper than a street price.
- Doing Thailand or Vietnam on the same trip? A regional Asia plan covers the whole loop.
How to get connected
- Download Num and pick Cambodia.
- Choose a plan and pay with Apple Pay.
- Scan the QR code the app gives you — Settings → Cellular → Add eSIM.
- Turn on data roaming for the Num line when you land.
Questions about Cambodia
How much does an eSIM for Cambodia cost?
Plans start at $3.48. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Cambodia eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
Is there an unlimited data eSIM for Cambodia?
Num does not sell unlimited plans for Cambodia. The closest are the daily-allowance plans, such as 1 GB per day, which give a fixed amount each day for the length of the trip. For most travellers the fixed bundles, from 500 MB to 50 GB, are better value.
Which networks does a Num Cambodia eSIM use?
It connects to Cellcard and Metfone and picks the strongest available network automatically. 7 of the 14 plans support 5G; the rest run on 4G/LTE.
Do I get a Cambodia phone number with the eSIM?
No. Num eSIMs are data-only. Your own number stays active on your existing SIM for calls and texts, and WhatsApp, iMessage and other messaging apps keep working over the eSIM's data. If you need a local number, see our guide to eSIMs with a phone number.
What is the best eSIM for Cambodia?
It depends on how long you stay and how much you use maps and video. On this page the best value per gigabyte is 10 GB per day for 1 day at $13.86 ($1.39); the trip-length picks match a plan to a weekend, a week, two weeks and a month.
