Airalo -- Best Overall Coverage
Airalo scores 8.9/10 in this comparison's matrix and prices Budapest plans from $4.50/GB, the highest fixed rate among the five compared and more than five times Budapest's own $0.79/GB local floor. Its Eurolink bundle, covering 39 European countries on one eSIM, suits a Budapest stop paired with a wider Central European itinerary more than a single-city stay.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- Customer support slower than premium providers (4-6 hour email response)
HelloRoam -- Best Coverage + Value
HelloRoam scores 8.6/10 overall and prices Budapest plans from $3.50/GB, the second-cheapest fixed rate among the five compared, though still well above the city's own $0.79/GB local floor. Its 204+ carrier partnerships route through local networks including Yettel and Vodafone HU rather than through a roaming intermediary.
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Email-only support with 12-24 hour response times
- Newer brand (launched August 2025) with shorter track record
- App store ratings still building compared to Airalo
Holafly -- Best Unlimited Data
Holafly's unlimited plan starts at $2.99/day, slightly above Budapest's own $2.62/day local unlimited rate, one of a smaller share of destinations in this comparison where the local price undercuts Holafly's general rate. Its 2GB daily volume before the fair-use throttle still comfortably covers Budapest's 70 Mbps average download speed for maps, messaging, and moderate streaming.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily prices Budapest plans from $3.99/GB and bundles a NordVPN connection into every plan at no extra cost, though Hungary's own enrichment data lists VPN use as unrestricted, so the bundled VPN works as a general privacy layer here rather than a way around any local block. Its 150-country footprint covers the wider Central European region well.
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 150 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
Nomad's $3.00/GB rate is the lowest fixed floor in the matrix, though Budapest's own $0.79/GB local price still runs well under it. Its 112-country footprint and 3.9/5 Coverage score are the narrowest of the five, a bigger factor on a Budapest trip extending into neighboring Central European countries than on a Budapest-only stay.
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with 24-48 hour response times
- Basic app compared to Airalo and Saily
- 112 countries, the narrowest footprint among the five providers
- Limited plan variety in some countries
