Airalo -- Best Overall Coverage
Airalo's $4.50/GB starting rate runs well above the Czech Republic's own $0.95/GB tracked local floor, though it still carries the highest Coverage score in the matrix at 4.9/5 across 200+ countries. Its Eurolink bundle, covering 39 European countries on one eSIM, suits travelers pairing Prague with a wider Central European itinerary.
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 the Czech Republic from $3.50/GB, above the country's own $0.95/GB tracked floor, which its 10GB tier already reaches. Its 204+ carrier partnerships and 63-language checkout matter given the tracked carriers' 5G reach stays concentrated in Prague and Brno rather than rural areas.
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 $2.99/day unlimited rate sits above the Czech Republic's own $2.62 base per-day unlimited rate before any multi-day discount applies, and its 4.8/5 Pricing score leads the matrix. The country's own 30-day unlimited tier prices at $2.15 per day, undercutting Holafly's flat daily rate on longer Prague stays.
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 the Czech Republic at $3.99/GB with a bundled NordVPN connection at no extra cost, useful since VPN access stays unrestricted per enrichment data. Its 150-country footprint and 4.6/5 App score still run well above the country's own $0.95/GB local pricing floor.
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 among the four outside providers, though it still runs well above the Czech Republic's own $0.95/GB tracked local rate. Its 24-48 hour email-only support window is the slowest of the five, a trade-off worth weighing against Prague's own tracked reliable metro-tunnel coverage.
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
