eSIM for Bulgaria

Buy a prepaid travel eSIM for Bulgaria and pay in cryptocurrency. You get local 4G/5G data on partner networks without a contract or a local address. No documents, no account and no email: you pay in crypto and the QR code appears on the page.

Part of our Europe and Balkans plans.

Buying an eSIM for Bulgaria

  1. Pick a plan that covers Bulgaria — a single-country plan is cheapest per gigabyte, a regional plan pays off the moment you cross a border.
  2. Pay with USDT, BTC, ETH, SOL, TON or XMR. No email address, no account, no card.
  3. Scan the QR that appears on the page. Do this at home over Wi-Fi rather than on airport Wi-Fi after landing.
  4. On arrival, set the eSIM as your data line and turn data roaming ON for it. This is the single most common reason a correctly installed profile shows no data in Bulgaria.

Coverage and network quality in Bulgaria

The profile attaches to local partner networks, so you are on the same towers local subscribers use — not a degraded roaming tier. 5G is widespread in Sofia, Plovdiv, Varna and Burgas.

Cities, the Black Sea coast and the motorways are well covered. The Rila and Pirin mountains lose signal in the valleys, and so do parts of the Rhodopes.

Speeds track the local network rather than the brand on your checkout page: no travel eSIM provider owns towers, all of them buy wholesale capacity from these same carriers.

Practical notes for Bulgaria

Summer on the coast means crowded networks in the evenings around Sunny Beach and Golden Sands. Ski resorts are covered at the base and thinner on the upper runs. If the trip continues into Greece, Romania or Serbia, the Balkans plan covers them all.

Frequently asked questions

Do I need an ID or KYC to buy an eSIM for Bulgaria?

No. Cypher eSIM never asks for a name, email, phone number or government ID. You pay in cryptocurrency and the QR code appears on the page — that is the whole flow, for Bulgaria and everywhere else we cover.

How good is coverage in Bulgaria?

Cities, the Black Sea coast and the motorways are well covered. The Rila and Pirin mountains lose signal in the valleys, and so do parts of the Rhodopes. Your phone picks whichever network has the best signal where you are, the same way a local handset does.

Can I install the eSIM before travelling to Bulgaria?

Yes, and you should. Install it at home over Wi-Fi; the plan only starts counting from the moment your device first connects to a network at the destination, so buying days ahead costs nothing.

Will I keep my own phone number in Bulgaria?

Yes. The eSIM is data-only and runs alongside your physical SIM, which keeps your number live for calls and SMS. Just make sure the eSIM is set as the data line so nothing routes over your home carrier at roaming rates.

Will it work at the ski resorts?

At the base stations and in the villages yes. Higher up the runs signal gets patchy, which is normal for the terrain.

Does it cover Greece too?

Not on the Bulgarian plan. The Balkans plan covers Bulgaria, Greece, Romania, Serbia and their neighbours on one profile.

Can I buy an eSIM with cryptocurrency?

Yes. Cypher eSIM accepts USDT (TRC-20, BEP-20, Arbitrum, Solana), Bitcoin including Lightning, Ethereum, Solana, USDC, DAI, Monero (XMR), TON. After payment, you receive your eSIM QR code within 60 seconds — no email, no login, no KYC required.

Is a no-KYC eSIM legal?

Yes, in most jurisdictions. KYC requirements vary by country, but using an anonymous eSIM for personal travel is legal in the US, EU, UK, and most of Asia.

How fast do I get the eSIM after payment?

Within 60 seconds. As soon as the crypto transaction is confirmed on-chain, the QR code is generated and shown on screen.
