Bulgaria

Yes, as long as you have an eSIM-capable, carrier-unlocked iPhone. That covers the iPhone XS, XR and every model released since, including the SE (2020) and newer. The Bulgaria travel eSIM installs alongside your existing SIM, so you keep your usual number on your main line while the eSIM carries data. After buying, you scan a QR code we email you, add the plan in Settings, and you're ready before you even land in Sofia. Remember it's data-only, so calls and texts run through WhatsApp, FaceTime or iMessage rather than your normal dialler. If you're unsure whether your handset is unlocked, check with your home carrier first, and our 24/7 support team can confirm compatibility before you travel.

Yes. The Bulgaria eSIM works on most recent eSIM-capable, unlocked Android phones. That includes Samsung Galaxy S20 and newer, the Z Fold and Z Flip range, Google Pixel 3 and later, plus many current models from brands like Motorola and Oppo. Installation is the same as on iPhone: you scan the QR code we email after purchase and add the data plan in your network settings. You keep your normal number on your physical SIM and let the eSIM handle mobile internet across Bulgaria. Because plans are data-only, calls and messages go through WhatsApp, FaceTime or similar VoIP apps. Older or network-locked handsets may not support eSIM, so if you're not certain, our support team is available around the clock to check your specific model.

The Bulgaria eSIM connects to Vivacom, one of the country's leading mobile networks, giving you fast, reliable prepaid data without roaming fees. Vivacom offers strong 5G and 4G/LTE coverage across the major hubs, so you'll get solid mobile internet in Sofia, Plovdiv and along the Black Sea coast around Varna and Burgas. Your phone connects automatically once you arrive and switch the eSIM on, with no manual network selection needed. Because this is a data-only travel eSIM, you'll use that Vivacom connection for maps, browsing, streaming and apps like WhatsApp, while your normal number stays on your home SIM. It's an easy, tourist-friendly alternative to expensive roaming or hunting for a local shop to buy a physical SIM.

Coverage on the Vivacom network is strongest in and around the big destinations like Sofia, Plovdiv and the Black Sea coast, where you'll typically see fast 5G or 4G data. Beyond the cities, populated towns, main roads and popular tourist spots are generally well served on 4G, so you can navigate, share photos and stay online while exploring. Heading into the Rila and Pirin mountains, the Rhodopes or remote rural valleys, signal can thin out or drop to slower speeds, as it would with any network in those areas. For a trip mixing city breaks with coastal resorts and day trips, the Bulgaria eSIM gives dependable mobile internet. Download offline maps before venturing into the high country, and our 24/7 team can help if you hit a coverage question.

It's quick. After you buy, we email you a QR code along with simple step-by-step instructions. On iPhone, go to Settings, Mobile Data, Add eSIM, then scan the code; on Android the path is similar under network or SIM settings. This installs the Bulgaria travel eSIM without removing your existing SIM. We recommend installing while you still have Wi-Fi at home, before you fly. Your data allowance and validity period don't start counting until the eSIM first connects to the Vivacom network once you arrive in Bulgaria, so installing early costs you nothing. When you land in Sofia or Varna, switch on the eSIM line, enable data roaming for that line only, and you're connected. If anything looks off, our support team is available 24/7 to walk you through it.

Yes, and we recommend it. You can scan the QR code and install the Bulgaria eSIM as soon as it arrives in your inbox, ideally over home Wi-Fi before your flight. Installing early does not start your plan: the data allowance and validity only begin when the eSIM first connects to the Vivacom network after you arrive in Bulgaria. That means you can set everything up in advance and land at Sofia or Burgas airport already configured, with no fiddling at the gate or queuing for a tourist SIM. Just keep the eSIM line switched off until you arrive, then enable it and turn on data roaming for that line. Doing the setup at home also means our 24/7 support can help while you still have a stable connection.

For most travellers, yes. Standard roaming charges from many home carriers can add up fast, especially outside the EU's roam-like-at-home zone or once data caps kick in. The Bulgaria eSIM uses a flat prepaid price you know upfront, with no roaming fees and no surprise bills when you get home. You pick a data plan that suits your trip and simply use it. If you run low, you top up by buying or adding another plan rather than paying inflated per-megabyte roaming rates. That makes budgeting easy whether you're city-hopping between Sofia and Plovdiv or relaxing on the Black Sea coast. EU travellers should always check their own roaming terms, but for visitors from outside the EU a prepaid travel eSIM is usually the far cheaper way to stay online.

It depends on how you use your phone. For a week of light use, mostly maps, messaging, WhatsApp and occasional browsing, many travellers are comfortable with around 3 to 5GB. If you stream music, upload lots of photos from the Black Sea beaches, use social media heavily or rely on the eSIM for video calls, plan for 7 to 10GB or more. Remember that data-heavy tasks like Netflix or long video calls eat allowance quickly, so connect to Wi-Fi at your hotel when you can. The good news is you're never locked in: if you run low mid-trip you simply top up with another plan rather than overpaying upfront. Choose a slightly larger plan if you're unsure, and our 24/7 support can help you gauge the right amount of prepaid data.

Absolutely, that's how most people use it. The Bulgaria eSIM is data-only, so apps like WhatsApp, FaceTime, iMessage, Messenger and other VoIP services work perfectly over the mobile internet it provides. Because eSIM and physical SIM run side by side on dual-SIM phones, you keep your usual phone number on your home SIM the whole time. The trick is to turn data roaming off on that home line so it doesn't rack up charges, while letting the eSIM carry your data. WhatsApp stays tied to your normal number, so friends and family message you exactly as they always do, whether you're in Sofia or on the coast. For regular calls and texts to non-app numbers, just use WhatsApp or another data app instead of the standard dialler.

Yes, personal hotspot and tethering are supported on the Bulgaria eSIM. You can share your connection with a laptop, tablet or a travel companion's phone, which is handy if you're working from a cafe in Plovdiv or keeping the family online at a Black Sea resort. Any data used over the hotspot draws from the same allowance as your phone, so a few people streaming or video calling will get through your plan faster. Just enable the personal hotspot in your settings as you normally would once the eSIM is active. If you expect to tether often, pick a larger data plan, and remember you can always top up with another plan mid-trip rather than overpaying upfront. Our 24/7 support team can help if hotspot doesn't switch on first time.

The best Bulgaria eSIM is one that gives strong coverage, fair upfront pricing and an easy setup, which is exactly what the GulfData Bulgaria travel eSIM offers. It runs on Vivacom, a leading local network, with fast 5G and 4G data across Sofia, Plovdiv and the Black Sea coast, plus reliable mobile internet on main routes and tourist areas in between. You install it in minutes by scanning a QR code, keep your normal number on your home SIM, and pay a flat prepaid price with no roaming fees. Hotspot sharing is supported, top-ups are simple if you run low, and 24/7 support is on hand before and during your trip. For most tourists and business travellers it's a cheaper, simpler alternative to roaming or buying a physical tourist SIM on arrival.
