coverage
Saily covers 150 countries with strong presence in Europe, North America, and popular Asian destinations. The VPN integration is active globally, so your traffic is encrypted regardless of which network you connect to — critical on hotel and airport Wi-Fi where packet sniffing is common.
speed
Saily uses competitive Tier-1 carriers in major markets. The VPN overhead adds minimal latency in our testing (typically under 5 ms on nearby servers). 4G LTE and 5G available on supported networks.
app
Saily's app is clean and modern. VPN toggle is integrated directly into the same interface that manages your eSIM — no switching between apps. App ratings: 4.5 on iOS, 4.3 on Android.
pricing
Plans start from $3.99/GB. The VPN protection is built in — no add-on cost. For travelers who would otherwise pay separately for a VPN and a data SIM, Saily offers a combined solution that can be cost-effective.
support
Email-only support with 12–24 hour response times. No live chat, no WhatsApp. Quality is good when responses arrive, but the lack of real-time channels is a significant gap for travelers in urgent situations.
Final Verdict
Choose Saily if privacy is your top priority and you want VPN protection built into your travel data plan. For maximum country coverage, choose Airalo. For unlimited data, choose Holafly. Saily carves a specific niche for security-conscious travelers who want one app to handle both connectivity and privacy.
