Airalo: The Market Leader
Airalo set the playbook for travel eSIMs and still leads on sheer catalog breadth. 200+ countries, thousands of plans, a polished app, and competitive pricing. The comparison everyone else gets measured against.
Where it wins: SE Asia (best network partnerships), solo country trips, first-time eSIM users who want to start safe.
Where it loses: No automatic country switching for multi-country trips.

- Plans for 200+ countries from a few dollars
- Keep your number; no physical SIM swap
Yesim: The Unlimited Data Pick
The unique selling point: actual unlimited plans in many destinations. In a market where almost every eSIM provider sells capped plans only, Yesim’s unlimited tier genuinely solves a different problem. Also has a built-in VPN: useful on public WiFi in hotels and airports.
Where it wins: Remote workers and heavy streamers who need guaranteed data, unlimited travel, and anyone who’s been surprised by a tiny 1GB plan running out on day two.
Where it loses: SE Asia coverage isn’t quite as deep as Airalo’s. No GigSky-tier business reliability.
See our full Yesim review for the unlimited-data breakdown, including its built-in VPN: useful alongside (not instead of) a dedicated travel VPN if you handle banking or work logins on public Wi-Fi.
Get Yesim eSIMGigSky: The Business Travel Option
Founded in 2012, GigSky was one of the original travel eSIM providers before the category existed. It charges 20-40% more than Airalo, and for most leisure travelers, that premium is hard to justify. Where it earns its cost: major business corridors (London, NYC, Tokyo, Dubai, Singapore, Frankfurt) where reliable 4G/5G and solid customer support matter more than saving $3.
Where it wins: Business trips to major cities where connectivity can’t fail, enterprise accounts, travelers who expense it and need proven reliability.
Where it loses: Every price-sensitive scenario. Leisure travel in Asia or Eastern Europe where cheaper options perform identically.
Saily: The Privacy-First Choice
Nord Security (the company behind NordVPN and NordPass) built Saily as their travel eSIM. The result: institutional-grade privacy credentials that no other eSIM provider can match. Clean app, competitive pricing, 200+ destinations.
Where it wins: Privacy-conscious travelers, journalists and activists going to countries where browsing is monitored, anyone who already trusts the NordVPN ecosystem.
Where it loses: 200+ countries versus the 200+ catalog of Airalo/Yesim. Coverage in SE Asia is thinner.
Get Saily eSIMDrimsim: The Multi-Country Specialist
One account, one credit balance, 190+ countries, automatic network switching when you cross borders. No per-country plan shopping, no activation timing. You pay a slight premium per GB versus Airalo/Yesim for popular destinations, but you gain frictionless multi-country coverage: including many unusual destinations where destination-specific eSIMs don’t reach.
Where it wins: Complex 4+ country itineraries, trips to off-the-beaten-path countries, travelers who’ve been burned by activation logistics at border crossings.
Where it loses: Single-country trips where Airalo/Yesim are cheaper per GB. No unlimited plans.

What to Check Before Buying Any eSIM
- Phone compatibility: eSIM-capable + network-unlocked (Settings > Add eSIM or dial *#06# for EID).
- Country coverage: Verify your specific destination in the provider’s app before purchasing.
- Data caps vs. unlimited: Know your daily usage. A 1GB plan lasts most light users 2-3 days. Remote workers need 3GB+ per week minimum.
- Regional plans vs. single-country: If you’re visiting 2-3 neighboring countries, check if a regional plan (EU, SE Asia) is available: often cheaper than country-by-country.
- Activation timing: Most eSIMs activate on first use, not on purchase. You can install before your trip and activate when you land.
