Holafly vs Saily

Holafly charges a flat daily rate for unlimited data — $2.46-$4.10/day on 5- to 30-day plans in most destinations. Saily sells capped plans (5GB for 30 days is $7.99 in Thailand and $10.99 in Japan) and, in most countries, unlimited plans of its own.

For a light data user doing 500MB-1GB per day, Saily's capped plans are substantially cheaper. A week in Thailand costs $7.99 on Saily (5GB, 30-day plan) versus $27.50 for Holafly's 7-day unlimited plan. That's real savings if you don't need unlimited.

Heavy users can stay with Saily too. If you're burning through 2-3GB daily with video calls, streaming, and hotspot use, Saily's 7-day unlimited plan is $20.99 in Thailand and $26.99 in Japan, versus $27.50 on Holafly in both.

Saily's capped plans are straightforward — buy 5GB, use 5GB, you're done. In most destinations Saily also sells unlimited plans, so heavy users aren't stuck managing a cap.

Holafly markets unlimited data, and it genuinely delivers on that promise for the vast majority of travelers. Holafly doesn't publish a fixed fair-use threshold, but local operators may slow speeds after very heavy use rather than cutting you off entirely. Most travelers on typical usage won't notice it.

The psychological difference matters more than the technical one. With Saily, you're always aware of your remaining data. With Holafly, you forget about it entirely. For some travelers, that mental freedom is worth the premium. Others prefer the discipline of a budget-friendly cap.

Saily and Holafly both list 200+ destinations, so coverage breadth is no longer a real gap. For popular tourist destinations across Europe, Asia, and the Americas, both work fine. For less traveled regions — much of Africa, Central Asia, Pacific Islands — check that your specific destination is listed with each provider before buying.

Where they differ is plan type: Holafly sells unlimited plans of 1–90 days in most destinations, while Saily pairs capped plans with unlimited options in many countries, plus Europe and Global plans.

Both apps handle the basics well — browse plans, purchase, install, activate. Neither is complicated. A first-time eSIM user can go from download to connected in under 10 minutes with either provider.

Saily's app is notably cleaner and more modern. The interface feels like it was designed in 2023 (because it was), with a focused flow that doesn't overwhelm you with options. Nord Security's design team clearly brought their consumer product experience to the table.

Holafly's app is functional and gets the job done, but it's more utilitarian. The standout on Holafly's side is 24/7 support over WhatsApp as well as chat — if something goes wrong during setup, you can get help on whichever channel is easiest.

Holafly is strong here. 24/7 live chat with sub-15-minute response times, multilingual support in English, Spanish, French, and German, plus WhatsApp support for travelers who don't want to navigate an app while troubleshooting abroad. For an eSIM provider, this level of support is exceptional.

Saily also offers 24/7 live chat plus email, so you can reach someone at any hour with either provider. Holafly's extra channel is WhatsApp, which is handy if you'd rather not navigate an app while troubleshooting abroad.

Holafly has also been operating since 2017 — about six years longer than Saily. That translates to more real-world troubleshooting experience and more documented solutions for edge cases across its 200+ destinations.
