eSIM for Romania: The Complete 2026 Travel Guide

Romania rewards the traveler who moves around: Bucharest for a night, then Brașov and the castles, a road trip through Transylvania, maybe the Black Sea at Mamaia or a ski week at Poiana Brașov. Every leg of that runs on navigation, a ride app and a booking confirmation on your phone. A Romania eSIM keeps all of it working from the moment you land at Otopeni — and Romania happens to have some of the fastest mobile internet in Europe.

Does an eSIM work in Romania?

Yes, and unusually well. Romania's three national networks — Orange Romania, Vodafone Romania and Digi — are fast even by Western European standards, and a Romania eSIM from AirPlans connects to them at up to 5G in Bucharest, Cluj, Brașov, Timișoara, Iași and Constanța, with strong 4G/LTE on the highways and in the mountain towns of Transylvania. The only genuinely weak spots are remote Carpathian valleys and the Danube Delta channels — true for any SIM.

Your phone needs eSIM support: every iPhone from XS/XR up, recent Samsung Galaxy S and Z, Pixel 3 and newer, and most flagship Androids. Check the compatibility list if unsure.

How much data do you need in Romania?

1 GB per day is a comfortable baseline. Navigation on a Transylvania road trip is the main data cost; city Wi-Fi in cafés and hotels is generally good.

• Bucharest city break (3 days): 3 GB.
• A week — Bucharest plus Brașov, Sighișoara, Sibiu: 5–10 GB, mostly navigation and photos.
• Two weeks, a ski trip, or working remotely: 20 GB or an unlimited plan. Romania unlimited plans give a daily high-speed allowance and then slow down instead of cutting off.

Which Romania eSIM plan should you pick?

AirPlans lists around fifty Romania plans, from 1 day to a full year, starting from about $3, including a few data + calls plans with minutes. Live prices are on the Romania eSIM page and update in real time — what you see is what you pay. Before you choose:

• Validity starts when you connect in Romania, not at purchase.
• Top-up is available on most Romania plans from your account.
• Romania is in the EU. If the trip continues to Hungary, Bulgaria or beyond, a regional Europe eSIM covers the whole route on one plan — compare it against a single-country plan on the product pages.

Set it up before you fly

• Buy the plan. The QR code arrives by email at once and sits in your AirPlans account under My eSIMs.
• Scan it from the phone's settings (iPhone: Settings → Cellular → Add eSIM; Android: Settings → Network & Internet → SIMs → Add eSIM). Name the line "Romania".
• Keep the new line off until you land.
• At Otopeni: switch the Romania line on, set it as Mobile Data, enable Data Roaming for that line only. Home SIM stays on for calls and SMS, its own data roaming off.

The installation guide has screenshots for every phone.

Local tips

• Getting around: Bolt and Uber both work in Bucharest, Cluj and Brașov and are the safe way to avoid taxi overcharging — book at the airport kerb.
• Transylvania by car: the Transfăgărășan and Transalpina mountain roads are spectacular and have signal at the viewpoints but not in every valley; download the route before you set off.
• Trains: the CFR app sells tickets; coverage along the main Bucharest–Brașov line is good.
• Black Sea: Mamaia and Constanța have strong coverage on the beach strip.
• Hotspot: tethering is allowed, so one eSIM can serve a laptop or a second phone.

Your own number stays yours

The eSIM is a second, data-only line next to your regular SIM. Your number and WhatsApp are untouched — here is how that works.
