Most modern smartphones (iPhone XS/XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer) are eSIM compatible. Budapest has good 4G and expanding 5G coverage, particularly in the city center. With a HotelESIM eSIM, your device will automatically connect to the best available network (Telekom HU, Vodafone Hungary) for optimal speeds.
