How do you get a mobile phone number in Hungary in 2026?

Visit an official Telekom, Yettel, or One retail store rather than relying on a petrol-station pack alone. Staff record your passport or other accepted photo ID against the prepaid contract. Telekom’s English guidance states that foreigners without a Hungarian-issued ID card must complete data verification in a store; an online path for foreign passports is not the default. Non-EU visitors should bring a passport. Ask for a working email so the operator can send the prepaid contract.

Bring residence or address proof if the desk asks, including a lakcímkártya when you have one: Register your address. eSIMs sold as short-trip travel products can unlock data without a local number, but salary and bank OTP flows still prefer a registered Hungarian SIM.

Hungarian prepaid rules require periodic adategyeztetés. Operators warn customers by SMS near the anniversary. Hungarian ID holders can often renew online; foreign passport holders usually return to a branded store with the SIM and ID. Miss the window and the line can die just when a bank OTP arrives: Open a bank account.

Postpaid contracts need stronger stay and credit checks. Compare mobile spend with fibre and BKK passes in Utilities, internet and transport. Budapest store density is highest; Debrecen and Szeged still have branded shops if you settle outside the capital: Living in Budapest.
