What a Bultel eSIM costs
The cheapest published plan on the Bulgaria travel eSIM is $4.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $5.00, a 3 GB / 30 day plan is also $5.00, and a 5 GB / 30 day plan is $7.00. Larger buckets go up to 20 GB for 30 days at $18.00. Unlimited data is listed separately on the same product, from $10.35 for 3 days. Note the 2 GB / 15 day and 3 GB / 30 day plans sit at the same price, so the longer validity is the better buy. Buy the size that matches the trip, not a larger plan “just in case”.
Network
The plan is sold under the operator name Bultel and the supported country is Bulgaria. The product page publishes the speed as 4G. That is the figure to plan around. It is not a 5G product, and speed on the ground still depends on the mast, the handset, and the carrier Fair Usage Policy. Bulgaria is covered as one country on this plan, including Sofia, Plovdiv, Varna, and the Black Sea coast. It is not an EU-wide plan. It does not cover Romania, Greece, Turkey, or Serbia, so a day trip to Ruse or Edirne needs its own plan.
How much data you actually need
Maps, chat, and boarding passes sit inside 1 GB for a short stay. Photos and short video push a week toward 3 GB. A month of hotel Wi-Fi plus mobile backup is the 5 GB or 10 GB / 30 day plan. Hotspot use burns the allowance faster than the phone alone.
Unlimited data
Unlimited plans are listed on the same product page, from $10.35 for 3 days, $16.65 for 5 days, $22.53 for 7 days, $29.33 for 10 days, $40.80 for 15 days and $60.35 for 30 days. Unlimited still sits under a Fair Usage Policy, so a hotspot left on all day can be slowed. For a three-day city break the $10.35 unlimited plan costs more than 10 GB for 30 days at $10.80, so pick it only if you really will stream.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Bultel line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
Most visitors land at Sofia Airport (SOF), with seasonal charters into Varna (VAR) and Burgas (BOJ) on the coast. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Bulgaria”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Bulgaria eSIM?
$4.00 for 1 GB, valid 7 days, on the Bultel plan.
Q2: Which operator is on the plan?
Bultel. The supported country is Bulgaria.
Q3: Does it include calls and SMS?
No. It is a data plan. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
No. The product page lists the speed as 4G, not 5G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Will it work outside Bulgaria?
No. This plan is for Bulgaria and it is not an EU-wide plan, so buy a separate one for Romania, Greece, Turkey, or Serbia.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $10.35 for 3 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a week in Bulgaria, the $4.00 / 1 GB Bultel plan is the one to start with. Step up to 5 GB or 10 GB if you will be off hotel Wi-Fi most of the day. The published speed is 4G, and unlimited is available separately from $10.35.
