Holafly is the best unlimited eSIM provider in 2026. Pay per day, use as much data as you want. Simple pricing, 6-month refund policy, and 24/7 chat support. The clear choice for data-heavy travelers.
Holafly covers 178 countries with unlimited daily data plans. Coverage is strong in popular tourist destinations across Europe, Asia, and the Americas. Thinner in Africa and the Pacific compared to Airalo.
Holafly uses NTT Docomo in Japan, EE in the UK, and T-Mobile in the US. Speeds are strong until the fair use threshold kicks in, after which throttling reduces speeds to 256 Kbps-1 Mbps.
Holafly's app handles eSIM installation and plan management. The interface is straightforward but less feature-rich than Airalo. No real-time data tracking since plans are unlimited. App ratings: 4.4 on iOS, 4.2 on Android.
Unlimited daily plans start from $2.99/day and scale by trip length and destination. Heavy streamers and remote workers burning 10+ GB/week save significantly compared to per-GB alternatives.
24/7 chat and email support with response times under 15 minutes on chat. The team handles eSIM installation issues well. The 6-month refund policy is the most generous in the industry.
Choose Holafly if you stream video daily, work remotely, or want unlimited data without tracking usage. For light users under 5GB per trip, a fixed-data provider will cost less.
Our activation testing protocol covers three device categories: unlocked iPhones (XS through iPhone 16), Google Pixel (6 through 9), and Samsung Galaxy (S21 through S25). For each device we timed the full flow from plan purchase to first confirmed data packet, recording QR scan success rate, carrier handoff latency, and whether the provider's app correctly reflected the installed profile.
Holafly averaged under two minutes from QR scan to active data across all tested hardware. We noted unlimited plans activated without any top-up prompts. Data simply started once the carrier handoff completed.
All activation tests were conducted on carrier-unlocked devices. If your phone is carrier-locked, check with your operator before buying any eSIM. Read our buying guide for a full explanation of eSIM compatibility, or compare providers side-by-side on our destinations page.
