Free wifi everywhere - New York Café, Széchenyi Baths, most ruin bars in Jewish Quarter. McDonald's at Deák Ferenc tér reliable backup.

Mobile data: Magyar Telekom and Vodafone best coverage around Castle Hill. Skip airport tourist SIM cards - buy from Váci utca Telekom shop instead. 30GB monthly around 4000 HUF.

Café wifi spots: New York Café (tourist central but solid connection), Szamos Café near St Stephen's, Kazinczy utca places. Many laptop-friendly for digital nomads.

Public 'BudapestWiFi' works around Parliament and Chain Bridge but connection spotty in Buda hills. Don't rely on it for video calls.
