Question 1

Does Remindavo work with Hungarian phone numbers?

Accepted Answer

Yes. Remindavo fully supports Hungarian phone numbers starting with +36. It works across all three major Hungarian mobile network operators (MNOs): Magyar Telekom (the dominant carrier and former state telecom incumbent, operating mobile services under the T-Mobile Hungary brand and a subsidiary of Deutsche Telekom — the same group that operates T-Mobile in Germany, Austria, the Netherlands, Poland, and the United States), Vodafone Hungary (acquired by Hungarian conglomerate 4iG Group in 2023, keeping the Vodafone brand under a licensing agreement), and Yettel Hungary (formerly Telenor Hungary, rebranded as Yettel in April 2022 after Czech PPF Group — controlled by Renáta Kellner following Petr Kellner's death in 2021 — acquired Telenor's Central and Eastern European assets including operations in Bulgaria, Serbia, Hungary, Montenegro, and North Macedonia). Hungary's MVNO market includes Simple Mobile (operating on the Magyar Telekom network, operated by Simple Pay / OTP Group, Hungary's largest bank), Lidl Connect Hungary (operating on the Vodafone Hungary network, part of the pan-European Lidl Connect MVNO footprint), and CherryMobile. Hungarian mobile numbers use the domestic format 06-XX-XXX-XXXX (where 06 is the trunk prefix replaced by +36 in international format) and belong to number ranges: +36 20, +36 30, and +36 31 (Magyar Telekom / T-Mobile), +36 70 (Vodafone Hungary), and +36 50 (Yettel). When entering your Hungarian number in Remindavo, select Hungary (+36) and enter without the leading 06 — for example, 06-20-123-4567 becomes +36 20 123 4567. Remindavo places a test verification call immediately after you add your number to confirm it can reach you.

Question 2

Is Remindavo compliant with Hungary's data protection law (GDPR / NAIH)?

Accepted Answer

Yes. Hungary is an EU member state (since May 2004) and applies the EU General Data Protection Regulation (GDPR, Regulation 2016/679) as directly applicable law since May 25, 2018. The Hungarian data protection supervisory authority is the Nemzeti Adatvédelmi és Információszabadság Hatóság (NAIH — National Authority for Data Protection and Freedom of Information), established in 2012 as successor to the Parliamentary Commissioner for Data Protection and Freedom of Information. NAIH enforces GDPR rights including the right of access (Article 15), right to rectification (Article 16), right to erasure / right to be forgotten (Article 17), right to restriction of processing (Article 18), right to data portability (Article 20), and right to object (Article 21). Hungary has also enacted national implementation legislation — the Infotv. (Act CXII of 2011 on the Right to Informational Self-Determination and Freedom of Information), updated to align with GDPR requirements — which governs data protection in areas where the GDPR permits national discretion. Remindavo collects only what is necessary to deliver the service — your calendar event times and phone number — and never sells or shares your personal data with third parties. You can request data deletion at any time at web.remindavo.com/delete-account.

Question 3

What time zone does Remindavo use for Hungary?

Accepted Answer

Remindavo uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) during daylight saving, following the EU DST schedule. Clocks in Hungary advance one hour on the last Sunday of March (typically between March 25 and March 31) and revert on the last Sunday of October (typically between October 25 and October 31). Hungary is always exactly 1 hour ahead of the United Kingdom: in winter, UK is on GMT (UTC+0) and Hungary is on CET (UTC+1); in summer, UK is on BST (UTC+1) and Hungary is on CEST (UTC+2) — the gap is a constant 1 hour throughout the year. Hungary shares the same time zone and DST schedule as Germany, Austria, the Czech Republic, Poland, Slovakia, Croatia, Slovenia, Serbia, North Macedonia, and many other Central European countries. Common CET/CEST reference points: when it is 9:00 AM CET (winter) in Budapest, it is 8:00 UTC and 3:00 AM EST (New York). When you connect your Google Calendar or Outlook to Remindavo, your calendar already stores event times in UTC, which Remindavo converts to your local CET or CEST automatically. No time zone configuration is needed.

Question 4

Does Remindavo work for business users in Budapest, Debrecen, Miskolc, Pécs, or Győr?

Accepted Answer

Yes. Remindavo works for any Hungarian mobile number regardless of the city — Budapest (the capital, home to around 1.7 million people and Hungary's commercial, financial, and cultural centre), Debrecen (Hungary's second-largest city, a major university and agricultural hub in the Great Plain / Alföld region), Miskolc (industrial city in northeastern Hungary), Pécs (cultural city in southern Transdanubia, UNESCO World Heritage site), Győr (automotive and industrial hub in northwestern Hungary near the Austrian and Slovak borders, home to Audi Hungary), Székesfehérvár (central Transdanubia, significant manufacturing base), Kecskemét (Mercedes-Benz Hungary plant), Nyíregyháza, Szombathely, Szolnok, Veszprém (European Capital of Culture 2023), Tatabánya, and all other Hungarian cities, towns, and regions. Hungary's economy includes significant automotive manufacturing (Mercedes-Benz, Audi, Samsung SDI, SK Innovation battery plants), IT and shared services (many major multinationals operate GBS and SSC centres in Budapest), pharmaceutical and biotech (Richter Gedeon, the largest Hungarian pharmaceutical company; Egis; Sanofi Budapest operations), financial services (OTP Bank, the largest Hungarian bank and a growing pan-European banking group), food and agriculture (Magyar Posta logistics network), and a growing startup ecosystem centred in Budapest's innovation districts.

Question 5

Can Remindavo call Hungarian mobile numbers starting with +36 20, +36 30, or +36 70?

Accepted Answer

Yes. Remindavo supports all current Hungarian mobile number ranges: +36 20 (Magyar Telekom / T-Mobile), +36 30 (Magyar Telekom / T-Mobile), +36 31 (Magyar Telekom / T-Mobile), +36 70 (Vodafone Hungary), and +36 50 (Yettel, formerly Telenor Hungary). Hungarian mobile numbers are typically presented domestically as 06-XX-XXX-XXXX (the 06 trunk prefix is used within Hungary). When entering your number in Remindavo, select the +36 country code and enter the number without the leading 06 — for example, if your number is 06-30-987-6543, enter +36 30 987 6543. The Remindavo verification call fires immediately after you save your number, so you know delivery is confirmed before your first calendar event.
