FullBars does not offer eSIM plans for Hungary that include a phone number or SMS capability. The provider sells only data‑only eSIMs for the country. Travelers who need to make calls or send messages can rely on VoIP and messaging apps such as WhatsApp, Telegram, or the iOS Messages service while connected to the data plan. However, some destinations may restrict or block particular services, so users should verify that the apps they depend on are accessible in Hungary before purchasing an eSIM from FullBars.
