Frequently asked questions
What is the cheapest eSIM for Hungary?
For a one-week trip with 5 GB, the cheapest plan we found is Airalo at $11.50 (5 GB, valid 7 days). For unlimited data for a week, Airalo is cheapest at $27.00. Prices checked November 4, 2026.
How much data do I need for a week in Hungary?
For maps, messaging and some social media, 3 to 5 GB is enough for most people for a week. If you stream video, use video calls or hotspot a laptop, get 10 GB or an unlimited plan.
Will my US phone number still work?
Yes. A travel eSIM is added next to your US line. Keep your US line on for calls and texts (your carrier may charge for those abroad) and set the travel eSIM as your data line. Turn off data roaming on your US line so you are not charged a day pass by accident.
Do I need an unlocked phone?
Yes. Your phone must support eSIM and be unlocked by your carrier. Most iPhones from the XS onward and recent Samsung Galaxy and Google Pixel phones support eSIM. Install the eSIM at home on Wi-Fi a day before you fly.
