FAQ
Is my phone compatible? Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy and Google Pixel models. Check for an eSIM option in your settings.
When should I install it? Install at home before your trip while you have Wi-Fi. Choose to activate it on arrival so your plan starts when you land.
Can I keep WhatsApp and my number? Yes. WhatsApp stays tied to your existing number, and your home SIM keeps receiving calls and texts. The eSIM just adds data.
Yes, eSIMs work throughout Romania. As long as your phone is eSIM-compatible and carrier-unlocked, a HelloSIM Romania eSIM connects to local partner networks for data.
Is my phone compatible with a HelloSIM eSIM for Romania?
Most phones from the iPhone XS/XR (2018) onward, Google Pixel 3 and newer, and Samsung Galaxy S20 and later support eSIM. Check your settings for an 'Add eSIM' option and make sure the phone is carrier-unlocked.
How do I install my HelloSIM eSIM before flying to Romania?
After purchase you receive a QR code by email. Scan it under Settings > Cellular/Mobile > Add eSIM while on Wi-Fi; you can install it before departure and switch it on when you land.
How do I activate my eSIM when I arrive in Romania?
Once in Romania, enable the HelloSIM line and turn on Data Roaming for that line in your settings. It should register on a local network within a few minutes.
Which networks does HelloSIM use in Romania?
HelloSIM connects through Romania's major operators such as Orange, Vodafone, and Digi, automatically selecting the strongest available signal.
Is there 5G on eSIM in Romania?
5G is available in Bucharest and larger cities like Cluj-Napoca, Timisoara, and Iasi where the network and your plan support it; elsewhere you'll typically get fast 4G/LTE.
Should I activate the eSIM before I fly or after landing?
You can install it before you fly, but the validity usually starts when it first connects to a Romanian network, so most travelers turn it on after landing.
Will I have signal at Bucharest Otopeni Airport (OTP)?
Yes, Henri Coanda (Otopeni) Airport has strong coverage, so your eSIM should connect as soon as you land and enable it.
How much data do I need for a week in Romania?
Light users (maps, chat, email) do fine with 3-5 GB a week, while heavier users who stream or tether should look at 10 GB or more.
Can I use my HelloSIM Romania eSIM elsewhere in Europe?
A Romania-only plan works only in Romania; if you're touring several countries, a HelloSIM Europe regional eSIM covers Romania plus other EU/EEA countries on one plan.
Can I tether or use a hotspot with my eSIM in Romania?
Yes, hotspot and tethering are supported, so you can share your connection with a laptop or another phone, subject to your plan's data allowance.
Will I keep my regular phone number while using the eSIM?
Yes. The eSIM adds a separate data line, so you keep your home SIM active for calls and texts and use the eSIM for data in a dual-SIM setup.
Does the HelloSIM eSIM include a Romanian phone number?
HelloSIM plans are data-only, so there is no local number. Use apps like WhatsApp, Signal, or FaceTime for calls and messaging over data.
What APN settings do I need in Romania?
Most eSIMs configure automatically, but if data doesn't work, HelloSIM provides the correct APN in your setup email to enter manually.
My eSIM shows no service in Romania, what do I do?
Confirm Data Roaming is on for the HelloSIM line, toggle Airplane mode off and on, or manually select a network like Orange or Vodafone in your carrier settings.
Is it safe to turn on data roaming for the eSIM?
Yes. Enable Data Roaming only for the HelloSIM line, not your home line; roaming here just means using local partner networks, and the prepaid plan means no surprise bills.
Can I make regular phone calls and send SMS with the eSIM?
The plan is data-only, so standard voice calls and SMS aren't included. Use internet-based calling and messaging apps instead.
How do I top up or add more data if I run out in Romania?
You can buy more data from your HelloSIM account or app at any time; top-ups apply to your existing eSIM without needing to reinstall it.
What's the emergency number in Romania?
Dial 112 for all emergencies (police, ambulance, fire). It works from any phone and reaches an operator who can respond in English.
What internet speeds can I expect in Romania?
Romania has some of Europe's fastest internet, so in cities you'll often see strong 4G/LTE and 5G speeds; rural and mountain areas can be slower.
Will the eSIM work in the Transylvanian countryside and Carpathian mountains?
Coverage is good along main routes and in towns like Brasov and Sibiu, but signal can drop in remote mountain valleys and forested areas.
How long is a HelloSIM Romania plan valid?
Plans come with a set validity (commonly 7, 15, or 30 days) that starts when the eSIM activates on a network. Pick one that matches your trip length.
Can I install the same eSIM on two phones?
No, each eSIM QR code can be installed on only one device. Buy a separate eSIM for each phone that needs data.
What happens to my eSIM data when I leave Romania?
On a Romania-only plan, data stops working once you leave the country, and any remaining allowance can't be used abroad unless you have a regional plan.
Is the HelloSIM eSIM good for a Bucharest city break?
Yes, a small data plan is ideal for navigation, ride-hailing, and staying online in Bucharest without hunting for Wi-Fi.
Can I use the eSIM for Google Maps and navigation while driving in Romania?
Yes. For road trips, download offline maps of Romania in advance so navigation keeps working even where the signal is weak.
Do I need to remove my physical SIM to use the eSIM?
No, keep your physical SIM in. Just set the HelloSIM eSIM as your data line and your home SIM stays available for calls and texts.
How quickly does the eSIM connect after I land?
Usually within a few minutes of enabling the line and data roaming. If it takes longer, restart the phone once you're on Romanian soil.
Can I buy and set up the eSIM at the last minute?
Yes, delivery is by email within minutes of purchase, so you can buy it at the airport or even after arriving, as long as you have Wi-Fi to install it.
Is public Wi-Fi enough, or should I get an eSIM for Romania?
Wi-Fi is common in Bucharest cafes and hotels, but an eSIM keeps you connected on the go for maps, transport apps, and safety.
Does the eSIM work on the Bucharest metro and public transport?
Coverage is generally good above ground and in many metro stations, so you can use transport apps and buy tickets online while connected.
Which cities in Romania have the best eSIM coverage?
Bucharest, Cluj-Napoca, Timisoara, Iasi, Constanta, and Brasov all have strong 4G/5G coverage from the major operators HelloSIM uses.
Can I get a refund if my eSIM doesn't work in Romania?
If the eSIM was never activated and there's a genuine technical issue, contact HelloSIM support; activated or used eSIMs generally aren't refundable, so test compatibility first.
How do I check compatibility before buying for a trip to Romania?
Dial *#06# to see whether your phone shows an EID (eSIM identifier), or check the manufacturer's eSIM support list. An EID means your device can use eSIM.
Will the eSIM work for a Danube Delta or Black Sea coast trip?
Coverage is reliable in Constanta and along the coast, though the remote Danube Delta channels can have patchy signal, so download maps beforehand.
Can I use the eSIM in neighboring countries like Bulgaria or Hungary?
Not on a Romania-only plan. Choose a HelloSIM Europe regional eSIM if your itinerary crosses into Bulgaria, Hungary, or other EU neighbors.
Does the eSIM support VoLTE and Wi-Fi calling?
Data services work over 4G/5G; VoLTE support depends on your device and the local network, while Wi-Fi calling routes through your home carrier, not the eSIM.
What should I do the night before my flight to Romania?
Install the eSIM QR code while on home Wi-Fi, label the line 'HelloSIM,' and leave it turned off until you arrive so the validity doesn't start early.
Is Romania part of EU roaming, and does that matter for my eSIM?
Romania is in the EU, which is why a HelloSIM Europe plan can roam across the region. For a single-country trip, the dedicated Romania eSIM is simplest.
Why won't my eSIM register on any Romanian network?
Make sure the line and data roaming are enabled and the phone is unlocked, then try a manual network search. If it still fails, reboot and contact HelloSIM support with your EID.
