- iOS version: iOS 12.1 or newer for full eSIM support.
- Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
- Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.
It depends. Romania is in the EU, so "Roam Like at Home" applies only to EU citizens.
- If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees.
- If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).
A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.
This specific plan is valid only within Romania (and the EU). This is a critical point. If you take a day trip to Belgrade (Serbia) or Chisinau (Moldova), your connection will stop at the border as they are not in the EU. For a seamless multi-country trip that includes these non-EU neighbors, you must check our Regional or Global eSIM plans.
Yes, absolutely. Romania has one of the best 4G/5G networks in the world, even in rural areas. Our eSIM connects to premium local networks (like Orange RO or Vodafone) to ensure you have a strong signal for Google Maps while driving the Transfăgărășan highway, hiking in the Carpathian Mountains, or visiting Bran Castle (Dracula's Castle).
To give you the fastest speed, our eSIM connects to Romania’s premium Tier-1 networks, typically Orange Romania or Vodafone Romania. These operators are famous for providing some of the fastest and most reliable 5G/LTE speeds in all of Europe, ensuring a high-quality connection.
Yes, 100%. Uber and Bolt are the essential apps for getting around in Bucharest, Cluj-Napoca, and other cities. Our eSIM provides high-speed, low-latency data, which is crucial for ordering a car from Otopeni (OTP) Airport, tracking your ride, and navigating the cities.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
Yes. Coverage is generally available on the famous Transfăgărășan road, but we recommend downloading offline maps for the highest tunnel sections near Bâlea Lake.
Mostly yes. While the massive thick walls of the Palace of Parliament in Bucharest can block signals deep inside, you will generally have coverage during the tour.
Signal is reliable in main hubs like Sulina or Tulcea, but expect the connection to drop to 3G or be lost deep in the remote channels of the Danube Delta biosphere.
Yes. The 24pay app is the standard way to buy bus and metro tickets digitally in Bucharest and Cluj-Napoca, requiring an active internet connection to avoid fines.
