Holafly sells only unlimited plans for Romania, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in Romania
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $10.43 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $1.49) |
| Airalo | $27.00 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $27.50 | No daily cap; fair use may slow very heavy use |
| Saily | $26.99 | 5 GB a day at full speed, then up to 1 Mbps |
| Nomad | $25.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $10.43. The cheapest of the others is Nomad at $25.00, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Networks and coverage in Romania
ONE eSIM's Romania plans run on Orange, with 5G where available, and Vodafone on 4G (your phone may show the operator's current brand name instead). Coverage is strong in Bucharest, Cluj-Napoca, Brașov, Timișoara and along the main roads; in the Carpathian valleys and the Danube Delta signal can drop, as with any Romanian network.
Which eSIM should you choose for Romania?
- Short trip, light use (up to 3 GB): ONE eSIM's 3 GB plan at $4.13 (15 days), the cheapest at that size.
- Two weeks or more (5 to 10 GB): ONE eSIM's 10 GB plan at $11.77 (30 days), the cheapest at that size.
- Heavy use (20 GB): Nomad at $20.00 (30 days) is the cheapest at 20 GB.
- Streaming or video calls every day: compare the unlimited plans above by how much full-speed data each gives a day.
How to set up your Romania eSIM
- Check your phone supports eSIM and is carrier-unlocked.
- Install the eSIM on Wi-Fi before you fly, so it is ready when you land.
- In Romania, turn on the eSIM line and data roaming for it, choose it for mobile data, and keep your home SIM's data roaming off to avoid charges.
Romania eSIM FAQ
- I have an EU SIM. Do I need an eSIM for Romania? Often not: Romania is in the EU, so "roam like at home" applies, within your plan's fair-use limit. An eSIM helps travellers from outside the EU, or anyone whose roaming allowance is small.
- Which networks does ONE eSIM use in Romania? Orange (5G) and Vodafone (4G).
- Does it work in Transylvania? Yes. Both networks cover Brașov, Sibiu, Sighișoara and Cluj-Napoca; mountain valleys and the Danube Delta can have weaker signal.
- How much is the cheapest Romania eSIM? ONE eSIM's 1 GB plan costs $1.57 and lasts 7 days; 5 GB is $6.55 for 30 days.
- Can I keep my home number working? Yes. Most eSIM phones are dual SIM, so calls and texts stay on your home number while the eSIM handles data.
How we check prices
We read each provider's public Romania page on 4 November 2026 and took its cheapest plan at or above each size, in US dollars before any coupon, with the validity in brackets; ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month and keep the date on the page and in the short answer. If a number is out of date, write to support@oneesim.app and we will correct it.
