Best travel eSIM Romania: 12 Cellulo plans that beat $18/day roaming
Updated September 9, 2026 · Cellulo Team
Land in Bucharest 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 Romania options on Cellulo start at $6 CAD and top out at $96 CAD for 30 days of unlimited data. Even the 7-day unlimited plan at $38 costs less than three days of carrier roaming.
For most Canadian travellers, an eSIM is the cleanest way to stay connected in Romania from the moment the plane lands. You can open Google Maps at the airport, call a rideshare, pull up your hotel booking, and message home without hunting for airport Wi-Fi or lining up at a SIM kiosk.

All of these are data-only eSIMs, so they do not include local calls or SMS. They activate automatically on arrival in Romania.

How much an eSIM saves in Romania
The math is not close. Canadian carriers charge $18/day for international roaming in Romania.
- 3 days: $54 in roaming vs $16 for unlimited data
- 7 days: $126 in roaming vs $38 for unlimited data
- 10 days: $180 in roaming vs $48 for unlimited data
- 15 days: $270 in roaming vs $67 for unlimited data
- 30 days: $540 in roaming vs $96 for unlimited data
A couple spending 10 days in Romania would pay $360 in roaming charges. Two 10-day unlimited Cellulo eSIMs cost $96 total. That is a $264 difference before tax.
The cheapest option is the 1 GB, 7-day plan for $6, which works if you mostly need maps, messaging, and occasional email. The best balance for a typical trip is the 7-day unlimited plan at $38. It gives you enough room for navigation, rideshare apps, restaurant searches, travel documents, and video calls home without watching a data meter.
Which Romania eSIM plan should you pick?
If your trip is built around Bucharest, Cluj-Napoca, Brasov, Sibiu, or a few train rides between cities, the 7-day or 10-day unlimited plans make the most sense. They remove the hassle of rationing data when you are using Google Maps all day, checking attraction hours, or uploading photos on the go.
If you are staying longer and using hotel or apartment Wi-Fi most nights, the 10 GB or 20 GB 30-day plans are stronger value. They cost less than two or three days of carrier roaming and leave enough room for work apps, translation tools, and regular hotspot-free travel use.
If you only need a safety net, the 2 GB for 15 days or 3 GB for 30 days plans are cheap enough to justify even for light travellers. They are a practical fit for someone who wants mobile data for airport arrival, directions, and booking confirmations, then expects to lean on Wi-Fi later.
How to use an eSIM in Romania without triggering roaming
Install the eSIM before you leave Canada. You need Wi-Fi for setup, and doing it at home is easier than trying to troubleshoot after landing.
Once the eSIM is installed, turn your Canadian line off completely before you land in Romania. Do not just disable data roaming. If your Canadian line stays active, your carrier can still register on a local network and trigger the $18/day roaming charge.
Use the Romania eSIM for all mobile data during the trip. If you need a one-time password or 2FA code sent to your Canadian number, turn that line on briefly, receive the text, then turn it off again.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too. The safer move is to leave the phone active and switch off only the Canadian line in your cellular settings.
What a Romania eSIM is good for on arrival
Romania is easy to navigate once you are connected. The problem is the first hour after landing, when you need data most. If you are arriving at Henri Coanda Airport or another major airport, you may need maps right away, a rideshare app, your hotel address, train details, or a booking email buried in your inbox.
A Romania eSIM solves that before the trip starts. Because these plans activate automatically on arrival in Romania, your phone can connect as soon as you land. That matters more than carrier marketing ever admits. No airport kiosk, no swapping plastic SIM cards, no relying on public Wi-Fi for anything sensitive.
These plans are data-only, so they are built for WhatsApp, FaceTime, Google Maps, Gmail, Slack, and browser-based travel tasks. If you need traditional calling or SMS, keep in mind that the eSIM itself does not include them.
Network coverage in Romania
A Romania eSIM connects to local networks in the country. In cities and major travel corridors, that is usually enough for normal travel use like maps, messaging, ride booking, and email. Coverage can be less consistent in rural or mountainous areas, so travellers heading deep into the Carpathians or remote villages should download offline maps before leaving a city.
If you want the best travel eSIM Romania option for your trip length and data needs, Cellulo lays out every plan side by side so you can pick one before you fly.
