Holafly vs Saily: Honest eSIM Provider Comparison

Overview

Holafly sells unlimited-data eSIMs priced by the day, while Saily sells fixed data bundles priced by the gigabyte. The right choice depends on how much data you actually use and how long you stay. This comparison covers coverage, pricing structure, fair use limits and the trade-offs of each model.

Holafly

About

Holafly is a travel eSIM brand built around unlimited data plans sold in fixed-day durations, such as 5, 10, 15 or 30 days. It is popular with travellers who want one flat price and no need to monitor a data balance. It also offers a range of regional and multi-country plans.

Price range

Unlimited plans generally start at roughly US$20 for short stays and rise to around US$100 or more for 30 days, depending on destination. Check current prices before buying.

Strengths

• Unlimited data means no running out mid-trip, which suits heavy users of video calls, streaming and maps
• Flat per-day-bundle pricing makes costs easy to predict before you leave
• Wide destination coverage, including regional plans for multi-country trips
• Plans are suited to short and medium trips where daily usage is hard to estimate

Weaknesses

• Unlimited plans are subject to a fair use policy, so speeds may be reduced after heavy usage, and hotspot rules can vary by plan
• Usually costs more than a small pay-per-GB bundle for light users who only need maps and messaging
• Plans are data-only, so there is no local phone number for calls or SMS

Saily

About

Saily is a data-only travel eSIM service from the team behind Nord's security products. It sells fixed data bundles, such as 1 GB, 3 GB or 5 GB, for set validity periods, so you pay only for the data you expect to use.

Price range

Small bundles start at roughly US$4 for 1 GB in many destinations, with larger bundles costing more per plan but less per GB. Prices vary by destination, so check current rates.

Strengths

• Pay-per-GB bundles are very cost-effective for light users who mostly need maps, messaging and email
• Many bundle sizes let you match a plan to your trip length and usage
• App-based management with top-ups and built-in security extras
• Coverage of 200+ destinations, as stated by the provider, with country and regional options

Weaknesses

• Heavy users can burn through a bundle quickly, and large bundles may end up costing more than an unlimited plan
• You need to track your data balance and top up if you run out
• Plans are data-only, so there is no local phone number for calls or SMS

Side by side

Verdict

Choose Holafly if you stream, take video calls or share a hotspot, and you want to stop thinking about data limits. Choose Saily if you mostly use maps, messaging and email, because a small bundle will usually cost far less. For stays under a week with light use, Saily is typically the cheaper pick. For longer, data-hungry trips, Holafly's flat pricing can be less stressful, provided you accept its fair use policy. Compare current prices for your exact destination, as both brands vary by country.

Where Fresim fits

Fresim takes a different approach: travel creators and brands open their own branded eSIM store, set their own prices and keep the difference between their price and their cost. Plans cover 190+ destinations and arrive instantly by email, where the buyer taps Install on iPhone (iOS 17.4+) or Install on Android (Android 10+) to set up in one tap, or scans the QR code to share it or install from another screen. Prices vary by destination and are set by each store, so you can buy from a creator you already trust.
