eSIM for Romania

In Romania your Simzora eSIM connects automatically to one of the country's main mobile networks, and stays on whichever gives the best signal where you are standing. Across Bucharest, Brașov and Cluj-Napoca you should get reliable 4G for maps, streaming and internet calls, with 5G reachable in parts of the larger cities. Coverage is honestly thinner and slower once you head into the Carpathian mountains, the Danube Delta and small rural villages, where the signal can drop to basic data or fade out for a while.

The eSIM joins these networks as an international roaming line rather than a local Romanian SIM, so you need to switch Data Roaming on for the Simzora line in your phone settings. This is completely normal for a travel eSIM and adds no extra charge, because the plan you bought already covers the data you use. If your home SIM is still in the phone, leave Data Roaming off for that line so only the Simzora eSIM uses the roaming connection.

If your phone shows No Service or will not connect after you land, switch Aeroplane Mode on for about fifteen seconds and then off again, which forces the eSIM to search for a network afresh. Signal can also dip inside thick stone buildings, old churches and the underground metro sections in Bucharest, so step towards a window or wait until you are back at street level. Most plans begin the moment you first connect in Romania, so you can install the eSIM over Wi-Fi at home and simply turn it on when you arrive.

Because this is a data-only roaming line you get no Romanian phone number and no SMS, so keep your home SIM active in another phone for any bank or login codes sent by text. Your roaming data may also leave the network through a gateway outside Romania, so some websites and apps can treat you as browsing from abroad and show a different language or ask you to verify again. WhatsApp, iMessage and other internet-based apps carry on working normally over the eSIM data.

• Install and activate the eSIM over home Wi-Fi a day or two before you fly, so it is ready to go and you are not hunting for signal at the airport.
• In your phone settings set the Simzora eSIM as your mobile data line and turn Data Roaming on for that line, while leaving your home number in place for calls and texts.
• Download offline maps for the Carpathian mountains, Transylvania's back roads and the Danube Delta before you set off, as coverage in those remote areas can be patchy and slow.
