Roamix is the best-value travel eSIM for most travelers. Plans start from $1.99 — cheaper than Airalo ($4.50), Nomad ($4.50), and GigSky (~$9). No app is required: buy, install, and manage entirely in a browser. Roamix also includes a 14-day refund window and 24/7 human support — policies most competitors don't match. For the widest country coverage (200+ destinations), Airalo, Saily, or Nomad may have a slight edge. For truly unlimited data, Holafly remains the top choice for heavy users.

How to choose the right travel eSIM
Check your destination
Make sure the provider covers the specific country or region you're traveling to. Coverage maps vary — some providers are stronger in Europe, others in Asia.
Match data to your usage
Light travelers (email, maps) use 1–3 GB per week. Remote workers or streamers may need 10 GB+. Use our free Data Calculator to estimate needs before you buy.
Read the fine print
Unlimited plans often throttle speeds after a threshold. Hotspot may be restricted. Refund policies vary significantly between providers — always check before buying.

Which travel eSIM providers do not require an app?
Roamix, Holafly, and Nomad all offer web-based checkout with no app download required. Airalo, Saily, GigSky, Ubigi, and Roamless require their proprietary apps to purchase and manage eSIM plans.
Which eSIM providers offer unlimited data plans?
Holafly offers unlimited data plans for most destinations, though speeds are throttled after a fair-use threshold. Saily's Ultra subscription also includes unlimited data, throttled to 1 Mbps after 30 GB. Most providers — including Roamix, Airalo, Nomad, GigSky, and Ubigi — sell capped plans that deliver full-speed data up to your chosen limit with no throttling.

Nomad offers the most generous window: 30 days from purchase if the eSIM has not been installed or activated. Roamix offers a 14-day refund window for uninstalled, unactivated eSIMs. Holafly and Saily refund only before activation. Airalo, GigSky, and Ubigi do not offer refunds after the eSIM is installed.
