# Airalo vs. Holafly vs. Saily (2026): Data Caps, Fair-Use Throttling & Hotspot Rules

Status: **WORKS** | Last verified: 2026-11-11

> **Verdict:** Pick Airalo or Nomad when you want unthrottled fixed-GB data and unrestricted laptop hotspot tethering; pick Saily when you want a single reusable eSIM profile across 190+ countries; pick Holafly when you want day-based unlimited data on a single phone without counting gigabytes.

## Official Claim vs. Verified Reality

- **Official claim:** All three providers market seamless global eSIM connectivity in 190–200+ destinations with instant QR or in-app installation.
- **Verified on the ground:** The core trade-off is Fixed-GB vs. 'Unlimited' Fair Use: (1) Holafly sells day-based Unlimited plans, but local partner carriers apply Fair Usage Policies (FUP) that can throttle speeds after 3–5 GB of heavy single-day usage, and hotspot sharing is capped at 500 MB–1 GB/day; (2) Airalo sells fixed-GB packs (1 GB to 20 GB) with zero daily speed throttling and 100% hotspot allowance; (3) Saily (by Nord Security) uses a single install-once eSIM profile so you never have to delete and reinstall eSIMs between trips.

## Before You Fly (Pre-Departure Checklist)

- Estimate whether you will tether a laptop: if you work remotely from trains or cafes, choose a fixed-GB plan (Airalo, Saily, or Nomad) rather than a day-pass unlimited plan with a 500 MB hotspot cap.
- If traveling to mainland China and you need ChatGPT without a separate VPN, verify that your plan routes through Singapore (Airalo Chinacom / Asialink).
- Label your eSIM line clearly in iOS/Android settings (e.g., 'Travel Data') and turn off 'Allow Cellular Data Switching' so your home SIM never racks up $10/day carrier roaming charges.

## Practical Limits & Failure Modes

- Airalo creates a new eSIM profile for each country or regional pack you buy (unless you top up the exact same pack), whereas Saily and Jetpac reuse one profile globally.
- Holafly's day count runs on 24-hour blocks from activation; activating right before a 14-hour flight wastes your first day.

## Recommended Providers

- **[Airalo](https://doesitworkin.com/go/airalo)** — *Best for transparent fixed-GB pricing & China/Asia routing* ($4.50 / 1 GB (7 days)): Full hotspot tethering up to your plan's total GB, Singapore exit routing for China/Asia, and 200+ country/regional packs starting at $4.50. *(Note: Requires installing a new eSIM profile when switching between unrelated single-country plans.)*
- **[Saily](https://doesitworkin.com/go/saily)** — *Best single-profile eSIM for multi-country travelers* ($3.99 / 1 GB (7 days)): Install the Saily eSIM once and add new country data plans in the app without scanning another QR code, plus built-in ad/tracker blocking. *(Note: Data-only; does not include local voice/SMS numbers.)*
- **[Holafly](https://doesitworkin.com/go/holafly)** — *Best for single-phone travelers who hate watching data meters* ($6.90 / 1 day unlimited): Custom day-length plans (1 to 90 days) with no hard data cutoff for maps, social media, and messaging. *(Note: Hotspot sharing is limited to 500 MB–1 GB per day.)*
- **[Nomad eSIM](https://doesitworkin.com/go/nomad)** — *Best runner-up for Asia-Pacific dual-carrier 5G* ($4.00 / 1 GB (7 days)): Strong multi-carrier partnerships in Japan, South Korea, China, and Southeast Asia with competitive 10–20 GB bundles. *(Note: App catalog separates Day Plans from Regular Fixed-GB Plans—pick Regular Plans for unrestricted hotspot.)*

## Frequently Asked Questions

### Can I keep two travel eSIMs installed on my iPhone at the same time?

Yes. Modern iPhones can store 8+ eSIM profiles and keep two lines active simultaneously (for example, your home SIM for SMS/iMessage and your travel eSIM for cellular data).

### Which eSIM is better if I need to tether my MacBook for Zoom calls?

Airalo, Saily, Nomad, or Ubigi on a fixed-GB plan (10 GB or 20 GB). Avoid day-pass unlimited plans like Holafly for laptop work because their 500 MB/day hotspot cap runs out in a single 30-minute video call.
