Best travel eSIM Bulgaria: plans that beat $18/day roaming
Updated September 9, 2026 · Cellulo Team
Land in Bulgaria without a plan and your Canadian carrier starts billing $18/day. Stay a week and that is $126 for one phone, or $252 for two people, before you have even posted a photo from Sofia or opened Google Maps in Plovdiv.
The best travel eSIM Bulgaria options on Cellulo cost from $6 CAD to $98 CAD depending on how long you are staying and how much data you actually need. Even the 7-day unlimited option at $37 undercuts a week of roaming by $89. If you only need light data, the savings get even sharper.
All Bulgaria plans on Cellulo are data-only eSIMs, so they do not include local calls or SMS. For most travellers, that is fine. WhatsApp, FaceTime, iMessage, Google Maps, Gmail, Uber alternatives, booking apps, and banking apps all work on data.
Best travel eSIM Bulgaria plans compared
If you want the short version, the 30-day 20GB plan at $28 CAD is the strongest middle ground for most travellers. It is enough data for maps, messaging, ride-hailing, email, and regular social posting without paying for unlimited data you may not use.

How much you save versus roaming in Bulgaria
The roaming math is not close.
A Canadian carrier charges $18/day in Bulgaria. That means:
- 3 days: $54 in roaming vs $16 for unlimited data
- 7 days: $126 in roaming vs $37 for unlimited data or $6 for 1GB
- 15 days: $270 in roaming vs $67 for unlimited data or $7 for 2GB
- 30 days: $540 in roaming vs $98 for unlimited data or $28 for 20GB
For a couple travelling for 10 days, carrier roaming hits $360. Two 10-day unlimited Bulgaria eSIMs cost $96 total. That is a $264 difference.
The practical benefit matters as much as the price. Your eSIM activates automatically on arrival in Bulgaria, so you can get online as soon as the plane lands instead of hunting for airport Wi-Fi or lining up at a SIM kiosk. That means maps work on the drive from the airport, your hotel confirmation is already in your inbox, and you can book a ride without guessing whether the terminal Wi-Fi will cooperate.
Which Bulgaria eSIM plan should you pick?
For most people, the 20GB 30-day plan at $28 CAD is the sweet spot. It gives you enough room for navigation, messaging, restaurant searches, email, and regular Instagram or TikTok uploads across a longer trip. That is why it is the most popular pick here.
If your trip is only a few days and you know you will be using your phone heavily for maps, video calls home, and constant social posting, the 3-day or 5-day unlimited plans make more sense than trying to ration data.
If you are stretching your budget, the 1GB 7-day plan for $6 or the 2GB 15-day plan for $7 can work, but only if you are disciplined. Those plans are best for travellers who mostly use hotel or apartment Wi-Fi and only need mobile data for directions, messages, and occasional lookups while out.
For longer stays, the 10GB 30-day plan at $17 is a strong low-risk option. It suits business travellers who need reliable data for Slack, email, and the occasional video call, but do not want to pay for unlimited. If you are working remotely full-time, tethering often, or uploading content daily, the 30-day unlimited plan is the safer choice.
How to use a Bulgaria eSIM without triggering roaming charges
Install the eSIM before you leave Canada. You need Wi-Fi for installation, and it is easier to sort out at home than after landing.
Once the eSIM is installed, turn your Canadian line off completely before you arrive in Bulgaria. Do not just disable data roaming. If your Canadian line stays active, your carrier can still register you on a partner network and trigger roaming charges.
Use the Bulgaria eSIM for all mobile data during the trip. If you need a one-time password or 2FA code sent to your Canadian number, turn that line on briefly, receive the text, then switch it off again.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too. The right move is to leave the phone active and switch off the Canadian line specifically in your cellular settings.
What coverage and performance should you expect in Bulgaria?
Your Cellulo eSIM connects to local networks in Bulgaria. In cities and major tourist areas, that is usually enough for the everyday travel basics: navigation, messaging, booking apps, mobile boarding passes, and calls over apps like WhatsApp or FaceTime.
The honest caveat is that rural coverage can be less consistent, especially if you are driving through mountain areas or smaller towns. If your trip includes a lot of time outside Sofia, Varna, Burgas, or Plovdiv, it is smarter to choose a plan with more data than you think you need so you are not forced onto unreliable public Wi-Fi.
If you want to stay connected in Bulgaria without handing your carrier $18 a day, start with Cellulo's Bulgaria eSIM plans and pick the one that matches your trip.
