What is a mobile SIM plan in Bulgaria?

A mobile SIM plan gives you calls, texts and mobile data on one of Bulgaria's networks, either as a monthly contract (abonament) or a prepaid (предплатена) SIM you top up as you go. Contracts usually bundle a generous data allowance, unlimited domestic calls and sometimes a subsidised handset, while prepaid SIMs suit lighter or occasional users and visitors. EU roaming rules let you use your allowance across the European Union at no extra charge.

How the Bulgarian market works

Mobile operators are regulated by the Communications Regulation Commission (CRC/KRS), which oversees spectrum, competition and consumer rules. Bulgaria has three mobile network operators plus resellers, and 4G is near-universal with 5G expanding in cities. Number portability lets you keep your number when switching. Prices are quoted in lev, with the euro peg at 1.95583 and euro adoption planned. EU roaming means your domestic allowance works across the EU.

Benefits

Large data bundles — contracts often include tens of gigabytes or unlimited data for streaming and browsing.

EU roaming included — use your allowance across the European Union without extra roaming charges.

Handset options — contracts can bundle a phone paid off over the term.

Prepaid flexibility — no commitment, top up only what you need, ideal for light users and visitors.

How to choose

Estimate your monthly data use and compare bundles on that basis, not just the headline price. Decide between a SIM-only deal and a handset contract — SIM-only is cheaper if you already have a phone. Check network coverage where you live and travel, contract length, and any early-termination fee. Compare 5G availability if that matters, and confirm EU roaming limits and any fair-use caps on unlimited plans.

Leading providers in Bulgaria

Vivacom, A1 Bulgaria and Yettel Bulgaria (formerly Telenor) are the three mobile network operators, each offering contract and prepaid plans with nationwide coverage and growing 5G. Bulsatcom also provides mobile services alongside its TV and internet offering. All operate under CRC oversight, support number portability, and sell online and through retail stores.

What it costs

SIM-only contracts range from budget plans with modest data to premium unlimited-data tariffs; handset contracts add the phone cost spread over the term. Prepaid SIMs cost only what you top up. Longer contracts sometimes carry lower monthly rates but include early-exit fees. Watch for promotional prices that rise after an introductory period, and compare the total cost over the contract term rather than the first-month price.

Protections and regulation

Mobile services are regulated by the Communications Regulation Commission, which enforces rules on contracts, transparency and switching. You have the right to port your number to another operator, and EU roaming regulation lets you use your plan across the EU under fair-use conditions. Contract terms, including any minimum period and termination fees, must be clearly disclosed before you sign.
