9 Best eSIMs for International Travel of 2026

Saily takes the top spot because its Europe pricing starts low and scales cleanly. The Europe page lists 1 GB for 7 days at US$4.99, 3 GB for 30 days at US$12.49, 5 GB at US$19.49 and 10 GB at US$35.99, with a 50 GB pack valid for 90 days at US$95.99. One plan covers 35 countries. The app adds things most rivals skip: an ad blocker that Saily says can cut data use by up to 28.6%, web protection that blocks malicious URLs, and virtual locations, which reflect the company's NordVPN background. You can buy a plan up to 180 days before a trip and it activates automatically when you land. The unlimited option is weaker: US$49.99 for 15 days, with 5 GB per day at full speed and then up to 1 Mbps. Travelers who need to make calls should look at Jetpac's voice packs or Yesim's virtual numbers.

Airalo is the runner-up because it offers the widest choice in one app. Its Europe eSIM lists 41 countries, more than any other regional plan we checked, and the page lets you switch between fixed data and unlimited plans. Unlimited Europe pricing runs from $11.50 for 3 days to $19.50 for 5 days, $27.00 for 7 days, $35.00 for 10 days, $49.00 for 15 days and $71.00 for 30 days. Travelers going beyond one region can buy a Global eSIM, which starts at $8.50. Airalo lets you top up an existing eSIM instead of installing a new one, and its renewals feature automatically renews a package when 10% of the data is left, so you do not run dry mid-trip. Support runs 24/7 in several languages, including by WhatsApp. The main drawback is price on longer unlimited stays, where Maya Mobile's 30-day global plan at USD 49.99 costs less.

Holafly is the easiest unlimited option because every Europe plan is unlimited and you only choose the number of days. The Europe price table lists $11.90 for 3 days, $20.50 for 5 days, $27.50 for 7 days, $37.50 for 10 days, $51.50 for 15 days and $76.50 for 30 days. The plan covers 33 destinations, including the UK and Ireland, and uses 5G where available. Two extras stand out: an Always On feature that adds 1 GB of backup data, and a free 24/7 doctor chat through MeetingDoctors. Holafly also gives you up to 6 months to request a refund under its policy. The limits matter, though. Hotspot sharing is capped at 1 GB per day, which rules it out as a laptop connection, and Holafly says a fair usage policy can slow speeds for up to one day. The plan is data only, with no local number, so calls go through apps like WhatsApp.

GigSky is the pick for short hops because you buy unlimited Europe data one day at a time. Its Europe table lists $3.14 for 1 day, $9.44 for 3 days, $22.04 for 7 days and $40.49 for 15 days, each shown as a 10% saving off the regular price. Unlike Holafly, GigSky lists unlimited hotspot sharing, which makes it a better choice if you work from a laptop on the road. New users can claim a free 100 MB trial plan with no credit card, enough to test that the eSIM installs before a trip. GigSky also sells cruise and land plans from $10.99 for dozens of named cruise lines, and eligible Visa cardholders can get complimentary data in 175+ countries. Check the country list before you buy: the Europe plan does not cover Armenia, Georgia or the Isle of Man. For trips longer than a week, Maya Mobile's flat plans cost less.

Maya Mobile simplifies international data into one plan: the same unlimited eSIM works in 165+ countries at the same price everywhere. Its plan page lists 3 days for USD 9.99, 7 days for USD 19.99, 14 days for USD 27.99 and 30 days for USD 49.99, which is USD 1.67 per day. That makes it the cheapest unlimited option for longer trips among the providers we checked, and the only one that does not change price by region. Maya says its unlimited data has no caps and no throttling, a stronger promise than Saily's 5 GB daily limit or Jetpac's 3 GB. You install the eSIM once, then turn on Auto Top-Up so the plan renews without a new install. There is also a Global + Cruise option. Light users pay for more than they need, since there are no small fixed packs, and the pages we checked did not state hotspot rules, so confirm that with support if you plan to tether.

Nomad is a solid fixed-data alternative to Saily, with Europe plans from US$5.50. The Europe page offers two coverage versions, a 35-country plan and a 36-country plan, and a ladder of fixed packs from 1 GB for 7 days to 50 GB for 30 days, plus unlimited plans for 5 and 10 days. Nomad says its eSIMs support tethering and hotspot, which Holafly limits, and if you run out you can buy an add-on plan that attaches to the same eSIM instead of installing a new one. Some Nomad plans include a local phone number, so check the plan details if you need one. When we fetched the page from our location, only the headline price showed in US dollars and the individual plan prices showed in euros, so confirm the US price at checkout. Nomad also notes that coverage may exclude overseas territories of the listed countries, which matters for trips to places like the Canary Islands or Madeira.

Ubigi is the value pick for travelers who use more data than a 1 GB pack allows. Its Europe plan gives 10 GB valid for 30 days for US$15, which works out to US$1.50 per gigabyte. The eSIM is run by Transatel, part of NTT, and is reusable across 200+ destinations, so you install it once and buy new plans for later trips. A feature called Smartstart starts the plan automatically when you arrive, so validity does not tick down while you are still at home. Ubigi also works on eSIM laptops running Windows 10/11, which few travel eSIMs mention, and the one-off plan allows data sharing. You can check your balance and top up instantly in the Ubigi app. The trade-offs: the plan is data only, so calls go through apps, and the Europe page we checked offered fixed data rather than an unlimited option. Light users will pay less with Saily's US$4.99 pack.

Jetpac stands out for extras rather than price. Its Europe page lists 30-day packs of 5 GB for USD 16, 10 GB for USD 22, 15 GB for USD 27, 30 GB for USD 29.99 and 40 GB for USD 34.99, plus an unlimited 30-day pack at USD 65.99. The unlimited pack gives the first 3 GB every 24 hours at standard speed, then up to 1 Mbps. Jetpac is one of the few providers here that sells calling: voice packs let you call any number across 50+ countries from $1.99 for 5 minutes, through the Jetpac app. Hotspot is unlimited, and packs of 3 GB and above include free WhatsApp chat so messages still go through if your data runs out. The most unusual perk is SmartDelay: register your flight in the app and, if it is delayed, you can use an airport lounge for free. The eSIM handles data roaming only, with no SMS, and its smallest Europe pack costs more than Saily's or Nomad's.

Yesim, run by Genesis Group AG in Switzerland, rounds out the list with features aimed at travelers who still need a phone line. Alongside unlimited day plans and fixed plans, it sells virtual numbers and offers a 20-minute calls add-on at checkout. A Europe & UK plan covers 33 countries, and plans can be activated within 180 days of purchase. Yesim says more than 4 million people use it and that its 24/7 support answers in 5 minutes on average. We ranked it last for two reasons. First, its pages showed only euro prices from our location, so we could not verify a US dollar price. Second, its plan details say hotspot depends on the operator and speeds may be limited under the operator's fair usage policy, which is less clear than GigSky's unlimited hotspot or Maya Mobile's no-throttling statement.
