Want the full picture, including when a local SIM is cheaper? Read our guide to choosing a travel eSIM.
A digital SIM you download to your phone instead of inserting a plastic card. You buy a data plan online, install it with a QR code or in the provider's app, and it connects to local networks when you arrive.
Only if your phone supports eSIM and is carrier-unlocked. Most flagship phones from about 2019 onwards support eSIM, but not every model or regional version. Check your phone's settings for an 'Add eSIM' option, and check the provider's compatibility list before you buy.
Holafly markets unlimited data, but its plans are subject to a fair use policy. Independent 2026 reviews report slower speeds after heavy daily use and limits on hotspot sharing. It's great for maps, messaging and browsing; heavy video or large uploads may be slowed.
Holafly told us the code can be reused, so keep it for your next trip. Discounts are set by Holafly and can change, so check the price at checkout.
Yes. If you buy through our links we may earn a commission, at no extra cost to you. It doesn't change what we tell you about eSIMs, including the downsides.
