Best travel eSIM Cambodia plans for Canadians
Updated August 9, 2026 · Cellulo Team
Land in Phnom Penh or Siem Reap without a plan and your Canadian carrier starts billing $18/day. Stay a week and that is $126 for one person, or $252 for two, just to use the phone you already brought.
The best travel eSIM Cambodia option is usually cheaper than one or two days of roaming. A 7-day 1GB Cellulo eSIM costs $7 CAD. Even the 10-day unlimited option is $49 CAD, which is still less than three days of carrier roaming.
Cambodia is the kind of trip where mobile data matters right away. You land, clear the airport, and need Google Maps, Grab, hotel confirmations, and messaging before you ever see decent Wi-Fi. If you are heading straight from the airport to a hotel, temple site, border crossing, or bus terminal, arriving with working data is easier than hunting for a SIM kiosk or trusting airport Wi-Fi.
All Cellulo Cambodia plans are data-only eSIMs, so they do not include calls or SMS. For most travellers, that is fine. WhatsApp, FaceTime, Google Meet, Slack, Gmail, and maps all work over data, which is what actually saves you when you are trying to find your driver, pull up a booking, translate a menu, or upload stories from Angkor Wat before the tour bus leaves.

A few numbers make the choice easier. A 5-day trip on carrier roaming costs $90. Cellulo's 5-day unlimited eSIM is $29 CAD, saving $61. A 15-day trip on roaming costs $270. The 15-day unlimited eSIM is $69 CAD, saving $201. If you only need maps, messaging, and occasional browsing, the 15-day 2GB plan at $10 CAD undercuts roaming by $260.
How to stay connected in Cambodia without roaming charges
The practical move is simple: install your eSIM before you leave Canada while you still have Wi-Fi. Cellulo's Cambodia plans activate automatically on arrival in Cambodia, so you do not need to scan anything in the airport after landing.
The part that trips people up is roaming protection. To avoid roaming charges in Cambodia, turn your Canadian line off completely in your phone's cellular settings before landing. Do not just switch off data roaming. If your Canadian SIM stays active, your carrier can still trigger roaming charges when the line connects.
If you need a one-time password or 2FA code from your Canadian number, turn that line on briefly, receive the code, then turn it off again. Use the Cambodia eSIM for all data.
Do not use Airplane Mode as your workaround. Airplane Mode disables the eSIM too. Turn off the Canadian line specifically and leave the travel eSIM active.
Which Cambodia eSIM plan makes the most sense
For most people, the 7-day unlimited plan at $41 CAD is the safest pick. It covers a standard Cambodia itinerary without forcing you to ration maps, rideshare use, uploads, or video calls home. It is also easy math against roaming: $126 through a Canadian carrier for seven days versus $41 on Cellulo.
If your trip is longer and you are mostly using maps, chat, email, and light social media, the 30-day 5GB plan at $19 CAD or 10GB plan at $30 CAD gives better value than paying for unlimited data you may never touch. If you are creating content daily, tethering occasionally, or working through the trip, the 20GB or unlimited 30-day options fit better.
Coverage depends on the local networks your eSIM connects to in Cambodia. In major tourist areas and cities, that is usually what most travellers need. In rural areas or remote islands, expect coverage to be less consistent than in Phnom Penh or Siem Reap.
eSIM Cambodia setup before you fly
Install the eSIM at home on Wi-Fi, confirm it is added to your phone, and label it clearly so you do not mix it up with your Canadian line. When you land, use the Cambodia eSIM for data, keep your Canadian line switched off, and your phone is ready for maps, hotel check-in emails, ride booking, translation apps, and secure messaging without an $18/day surprise.
