Bulgaria eSIM: Stay Connected from Sofia to the Black Sea
Land in Bulgaria with mobile data already working. Here is how an eSIM keeps you online across Sofia, Plovdiv and the coast without roaming fees.
Stepping off the plane in Sofia and hunting for a SIM card kiosk is the last thing you want after a long flight. With a Bulgaria eSIM, your phone is online the moment you land, no shop visit and no roaming shock on your bill.
Why use an eSIM in Bulgaria
An eSIM is a digital SIM you install before you even leave home. It downloads in minutes and runs alongside your normal SIM, so you keep your usual number for calls and WhatsApp while getting fast local data.
No physical card to swap or lose
Activate before departure, connect on arrival
Pay one clear price, with no surprise roaming charges
Keep your home number active for OTP codes and messages

FAQ
Will my phone work with an eSIM?
Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy and Google Pixel models. Check your settings for an eSIM or digital SIM option.
When should I install the eSIM?
Install it before you travel while you have Wi-Fi, then simply switch it on when you land in Bulgaria.
Can I keep my WhatsApp number?
Yes. WhatsApp stays linked to your original number even while you use the eSIM for data, so your chats and account are unchanged.
Frequently asked questions
Does a HelloSIM eSIM work in Bulgaria?
Yes. HelloSIM offers a Bulgaria data eSIM that connects to local networks, so you get online right after landing in Sofia, Plovdiv or Varna without buying a physical SIM card.
Is my phone compatible with an eSIM for Bulgaria?
Most recent phones support eSIM, including iPhone XS and newer, Google Pixel 3 and later, and recent Samsung Galaxy S and Note models. Dial *#06# to check for an EID, or look for 'Add eSIM' in your settings.
How do I check if my iPhone supports eSIM for Bulgaria?
Open Settings > Cellular and look for 'Add eSIM', or check Settings > General > About for an EID number. Every iPhone from the XS and XR onward supports eSIM as long as it's carrier-unlocked.
Does my phone need to be unlocked to use a Bulgaria eSIM?
Yes. A carrier-locked phone can't use third-party eSIMs like HelloSIM. If you bought your phone on a contract, ask your home carrier to unlock it before you travel.
Which networks does HelloSIM use in Bulgaria?
Bulgaria's main mobile operators are A1 Bulgaria, Yettel (formerly Telenor) and Vivacom, all with broad national coverage. HelloSIM connects through local partner networks to give your eSIM strong signal.
How do I buy and install a HelloSIM eSIM for Bulgaria?
Buy the Bulgaria plan on the HelloSIM website and you'll receive a QR code by email. Scan it in your phone's cellular settings over Wi-Fi before you fly, then enable data on arrival.
How do I install the eSIM QR code on iPhone for Bulgaria?
Go to Settings > Cellular > Add eSIM > Use QR Code and scan the code from your HelloSIM email. Label the line and select it as your data line once you're in Bulgaria.
How do I install the Bulgaria eSIM on an Android phone?
On most Android phones, go to Settings > Network & internet > SIMs > Add eSIM and scan the HelloSIM QR code. Menu wording differs slightly on Samsung, Pixel and Xiaomi devices.
Should I install my Bulgaria eSIM before flying or after landing?
Install it before you fly while you have good Wi-Fi, but wait to enable data until you arrive in Bulgaria if the plan's validity starts on first use. This saves days and avoids fiddling on airport Wi-Fi.
When does my Bulgaria eSIM plan start counting down?
Most HelloSIM plans begin their validity when the eSIM first connects to a Bulgarian network, not at purchase. So you can buy and install in advance without losing any data days.
Do I need to set an APN for my Bulgaria eSIM?
Usually not, since the APN configures automatically when the eSIM connects. If data doesn't work, HelloSIM provides the correct APN to enter manually under your cellular data settings.
Do I have to enable data roaming in Bulgaria for the eSIM?
Yes. Because the HelloSIM eSIM uses partner networks, you must turn on data roaming for the eSIM line. Keep roaming off on your home SIM so you aren't charged by your home carrier.
Can I keep my home number active while using a Bulgaria eSIM?
Yes. On a dual-SIM phone, keep your home SIM in for calls and texts on your usual number and use the HelloSIM eSIM for data. Just switch off data roaming on the home line.
Is 5G available in Bulgaria?
Yes. 5G is live in Bulgaria's larger cities including Sofia, Plovdiv, Varna and Burgas and keeps expanding, with fast 4G LTE almost everywhere else.
Is 4G widely available across Bulgaria?
Yes, 4G LTE covers cities, towns and most main roads well. You'll get reliable data across Sofia, Plovdiv, Varna, Burgas and Ruse, with weaker signal only in remote mountain areas.
What data speeds can I expect in Bulgaria?
In cities on 4G or 5G you can expect speeds fast enough for HD streaming, video calls and hotspot use. Speeds ease off in remote mountainous regions like parts of the Rila and Pirin ranges.
How much data do I need for a week in Bulgaria?
For a week of maps, messaging, social media and browsing, many travellers are comfortable with around 3 to 5 GB. Choose more if you stream video or use the hotspot a lot.
How much data should I get for two weeks in Bulgaria?
For a fortnight, roughly 7 to 10 GB suits typical use like navigation, social media and light streaming. Heavy streamers or remote workers should size up or plan to top up.
How much do Bulgaria eSIM data plans cost?
Prices depend on the data amount and validity, but eSIM plans are generally a transparent, affordable alternative to standard roaming. Check the live HelloSIM Bulgaria page for current tiers rather than a fixed figure.
Can I use my Bulgaria eSIM as a hotspot?
Yes, HelloSIM data plans support tethering, so you can share your connection with a laptop or tablet. Hotspot use draws from the same allowance, so it depletes your data faster.
Is the Bulgaria eSIM data only, or does it include calls and SMS?
HelloSIM plans are data-only and don't include a Bulgarian phone number for regular calls or texts. You can still call and message over data using WhatsApp, Viber, FaceTime or similar apps.
How do I make calls in Bulgaria with a data-only eSIM?
Use internet calling apps like Viber, WhatsApp, Messenger or FaceTime over your eSIM data. Viber is especially popular in Bulgaria, so most local contacts will already use it.
Will my eSIM work at Sofia Airport when I land?
Yes. Once your plan is active and data roaming is on, the eSIM connects to a local network shortly after you land at Sofia Airport (SOF), so you can book a taxi or open maps right away.
Does the eSIM work at Varna, Burgas and Plovdiv airports too?
Yes. Coverage isn't tied to a specific airport, so your eSIM connects to available networks whether you arrive in Sofia, Varna, Burgas or Plovdiv.
Can I use my Bulgaria eSIM in other EU countries?
A Bulgaria-only plan works within Bulgaria. If your trip also covers Greece, Romania or other EU states, choose a regional Europe eSIM so you're covered across borders instead of buying a single-country plan.
Is Bulgaria included in Europe or EU regional eSIM plans?
Yes. Bulgaria is an EU member, so it's included in HelloSIM's Europe regional plans, which are ideal if you're touring several European countries on one trip.
What happens when I run out of data in Bulgaria?
Your data stops until you top up. You can buy another HelloSIM bundle or top up your existing plan through your account, and service resumes once the new allowance is active.
How do I top up my Bulgaria eSIM?
Log in to your HelloSIM account, choose a top-up or new data plan for Bulgaria, and in most cases it applies to your existing eSIM automatically without scanning a new QR code.
My Bulgaria eSIM shows no service, what should I do?
Check that the eSIM line is selected for data, data roaming is enabled for it, and Airplane mode is off. Toggling Airplane mode on and off or restarting the phone usually forces it to re-register on a local network.
My eSIM won't register on a Bulgarian network, how do I fix it?
Turn off automatic network selection and manually choose A1, Yettel or Vivacom in your phone's network settings. Also confirm your plan is activated and you have signal where you are.
Why is my data slow in Bulgaria even with signal?
Slow speeds usually come from network congestion, being on 3G in a remote area, or your phone locking to a weaker band. Toggling Airplane mode or manually selecting another local network often restores faster 4G or 5G.
What is the emergency number in Bulgaria?
112 is the single emergency number in Bulgaria for police, ambulance and fire. It works from any phone even without an active data plan or credit.
Can I get a refund on a Bulgaria eSIM if my phone isn't compatible?
HelloSIM's refund policy generally covers unused eSIMs that haven't been installed or activated. Check compatibility before buying and contact HelloSIM support quickly if an unactivated plan has an issue.
How long is a Bulgaria eSIM data plan valid?
Validity varies by plan, commonly from a few days up to 30 days. Pick a validity window that matches your trip so your data doesn't expire before you leave.
Can I use the eSIM for Google Maps while driving in Bulgaria?
Yes, the eSIM gives you live data for Google Maps or Waze as you drive between Sofia, Plovdiv and the Black Sea coast. For mountain routes, download offline maps in advance in case signal drops.
Should I download offline maps before travelling in Bulgaria?
Yes, it's a good backup. Coverage is strong in cities and along main roads but can weaken in the Rila, Pirin and Rhodope mountains, so offline Google Maps keeps you navigating without signal.
Can I install the Bulgaria eSIM on more than one device?
No, each eSIM QR code installs on a single device only. If you want data on a second phone or tablet, you'll need a separate eSIM for it.
Do I need to remove my physical SIM to use the eSIM in Bulgaria?
No. On a dual-SIM phone the eSIM runs alongside your physical SIM. Keep your home SIM for calls, set the HelloSIM eSIM as your data line, and turn off roaming on the home SIM.
Is an eSIM cheaper than roaming with my home carrier in Bulgaria?
It often is, especially for travellers from outside the EU whose carriers charge high roaming rates. A dedicated HelloSIM data plan gives you a predictable price and a clear data allowance.
Can I share my eSIM connection with travel companions in Bulgaria?
Yes, turn on your phone's hotspot to share eSIM data with companions' phones or laptops. Everyone's usage comes out of your single data allowance, so a larger plan helps for group travel.
Will the eSIM work along the Black Sea coast resorts like Sunny Beach?
Yes. Popular coastal resorts such as Sunny Beach, Golden Sands and the areas around Varna and Burgas have solid network coverage, so your eSIM works well for maps, booking and messaging there.
What should I do with the eSIM after my Bulgaria trip?
Once your plan expires you can delete the eSIM from your phone's settings, or keep it installed in case you return and want to activate a new Bulgaria plan on the same profile later.
