Top travel-eSIM providers in 2026: Airalo vs Holafly vs Redteago vs Saily vs Ubigi
Five names dominate the travel-eSIM market. We've actually used all of them. Here's where each one wins.
Airalo — the safe pick
Biggest catalogue (200+ countries), cheapest entry tier in most regions, decent app. Throttle policy is opaque and customer service runs on tickets. Use it for: cheap regional packs, especially Asia-Pacific.
Holafly — unlimited data, opinionated
Single product per country, all unlimited (with a fair-use throttle past ~10 GB). Pricier than Airalo on a per-GB basis but you stop counting. Use it for: 1-week trips where you'd hate to ration data.
Redteago — value side
Aggressive prices in Europe and SEA, partner-driven so quality varies by region. Strong in Vietnam, Thailand, Indonesia. Use it for: longer stays where Airalo's regional packs run out.
Saily — Nord Security's entry
New (2024) but well-funded. Clean app, good UX. Catalogue still maturing. Use it for: when you want the same vendor as your VPN.
Ubigi — Transatel-backed, premium
5G on more networks than anyone else, monthly subscription option, decent business tooling. Pricier on short trips. Use it for: long-term travelers, road-warriors who care about speed.
How to pick
- One country, 1–2 weeks → Airalo or Saily. Cheapest per-GB.
- Multi-country Europe or Asia → Airalo regional pack or Redteago.
- Two-week unlimited and don't want to think → Holafly.
- Speed matters or recurring monthly → Ubigi.
- 6+ months and need stability → mix and match across providers on a single 9eSIM card.
The advantage of a programmable physical eSIM is you don't have to pick once. Load Airalo for Japan, Redteago for Indonesia, Ubigi for the long Berlin stint, all on the same card. Switch between them via the SIM toolkit in seconds.
