10 Best Travel Sim Cards of 2026

Airalo ranks first for travelers comparing roaming options because it replaces a carrier day pass with a prepaid package you control in an app. On its Europe page, unlimited packages run $11.50 for 3 days, $19.50 for 5 days, $27.00 for 7 days and $35.00 for 10 days, and one eSIM covers 41 countries, so a rail trip from Lisbon to Krakow needs no swaps. Fixed data packages sit next to the unlimited ones for lighter users. Two practical details help on longer trips: top-ups attach to the eSIM you already installed, and renewals can buy a new package automatically when 10% of your data is left. The trade-off is that Airalo sells data, not a phone line. You keep your home number on the physical SIM for texts, but calls abroad still bill through your carrier or go over apps. Compared with a $12 daily carrier pass, a 3-day Airalo package costs less than one day and a half of roaming.

Google Fi is the strongest carrier option here because international data is part of the plan rather than an add-on. Fi's plans page says Unlimited Premium, at $65 per month for one line, includes 50 GB of high-speed data in 200+ destinations and 256 kbps after that, plus calls from the US to 50+ destinations. The Flexible plan costs $20 per month for one line and charges $10 per GB for data at home and abroad in the same 200+ destinations. That makes Fi the least work of any option on this list: you land, turn on roaming and keep your own number for bank codes and calls home. Value depends on how much you travel. A traveler who uses 3 GB on a week abroad pays $30 in data on Flexible, while a prepaid Europe eSIM can cost less. Fi also only helps US residents, and the cheapest unlimited tier, Unlimited Essentials, has no international data.

Saily is the cheapest way on this list to avoid roaming charges on a short trip. Its Europe page lists 1 GB for 7 days at US$4.99, 3 GB for 30 days at US$12.49, 5 GB for 30 days at US$19.49 and 10 GB for 30 days at US$35.99, with a 50 GB pack valid for 90 days at US$95.99. Plans activate when you reach your destination or 180 days after purchase, so you can buy early. The app adds an ad blocker, web protection and virtual locations, which reflects its NordVPN background and helps small packs last. Every purchase also earns 3% back as Saily credits. Heavy users should look elsewhere: the unlimited Europe plan is US$49.99, and Saily does not provide a phone number, so calls and texts still depend on your home carrier or on apps.

Holafly suits travelers who would rather pay by the day than count gigabytes. Its Europe price table lists 3 days at $11.90, 5 days at $20.50, 7 days at $27.50, 10 days at $37.50, 15 days at $51.50 and 30 days at $76.50, all with unlimited data. The plan covers 33 destinations and connects to 5G where available. Holafly adds 1 GB of backup data every month at no cost, which it presents as a safety net, and allows 1 GB of hotspot sharing per day. That hotspot limit is the main drawback for anyone working from a laptop, and Orange Travel or a carrier pass is a better fit there. Holafly also sells data only, so you keep your home SIM for calls. Against Airalo, prices are close for short trips: $11.90 versus $11.50 for 3 days in Europe.

Orange Travel, which Orange says is the new name for Orange Holiday Europe, is the closest thing on this list to buying a local SIM. Orange's own guide, dated with prices as of November 12, 2026, lists data-only plans from $19.99 for 10 GB over 14 days and a data, calls and SMS plan with 20 GB for 14 days at $29.99. Calls plans include unlimited calls within Europe, SMS and a real European number, which helps with restaurant bookings and hotel check-ins. Orange says hotspot sharing is unrestricted and data is full-speed 4G or 5G with no throttling, and plans are refundable if the eSIM has not been activated. Coverage spans 38 European destinations, so it is no help in Asia or the Americas. Prices are higher than the cheapest data packs, and Orange's main travel shop showed euro prices when we checked from Europe.

For T-Mobile customers, the first question is whether a pass is needed at all. The roaming page says T-Mix Loaded, Experience Beyond and Go5G Next include up to 15 GB of high-speed data in 215+ countries and destinations, after which data is unlimited at up to 256 kbps, and calls bill at $0.50 per minute. When that is not enough, International Passes add data and free calls: $10 for 2 GB over 24 hours, $50 for 15 GB over 10 days, or $75 for 30 GB over 30 days, with hotspot use allowed. You keep your number, there is nothing to install, and you can set the pass start date in the T-Life app. The catch is cost and eligibility. Passes need a qualifying postpaid plan, only one can be active at a time, and $50 for 10 days is higher than an Airalo or Holafly plan of the same length.

Ubigi gives the best gigabyte-for-dollar deal among the plans we checked: its Europe page lists 10 GB valid for 30 days at US$15, which works out to US$1.50 per GB. Once the allowance runs out, you top up instantly in the app, which also shows your balance in real time. Ubigi says it works on eSIM phones and tablets and on Windows 10 and 11 laptops, which matters for travelers who want data on a laptop without tethering. The same eSIM can be reused for different countries, so your phone does not fill up with old profiles. The downsides are typical of data-only eSIMs: no phone number, and installation runs through a QR code emailed after purchase rather than a one-tap app install. There was no unlimited option on the Europe plan page, so streamers should look at Airalo or Holafly.

Mint Mobile customers do not need a separate eSIM for most short trips. Mint's roaming page lists four Minternational Pass options: 1 day with 1 GB of high-speed data, 60 minutes and 60 texts; 3 days with unlimited data, 3 GB of it at high speed, plus 200 minutes and 200 texts; 10 days with 10 GB at high speed, 500 minutes and 500 texts; and a 30-day pass with talk and text only. Passes work in 180+ countries, can be bought ahead and activated on arrival, and Mint adds free roaming in Canada with unlimited talk and text and 3 GB of high-speed data. The 1-day pass costs $5. The pass is only for existing Mint subscribers, and the minute caps are tight for anyone who calls home often, though Mint points to Wi-Fi calling for calls back to the US.

Nomad is a budget alternative to Saily for regional data. Its Europe page title gives a starting price of US$5.50, and the page offers a 35-country plan plus a 36-country version that includes Turkey, which helps on trips that cross from Greece to Istanbul. Fixed plans start at 1 GB for 7 days, unlimited plans are sold for 5 and 10 days, and add-on data attaches to the same eSIM when you run low. Nomad says its eSIMs support hotspot and tethering, and some of its eSIMs include a local phone number, so check plan details if you need one. Nomad also warns that coverage may not include overseas territories of the listed countries. From our location several plan prices displayed in euros, so confirm the currency at checkout. For most travelers Saily is slightly cheaper to start, and Airalo covers more countries.

Verizon TravelPass is the simplest roaming choice for Verizon customers and the most expensive per day. Verizon's travel page says TravelPass provides unlimited talk, text and data in 210+ countries and destinations at $12 per day, or $6 per day in Canada and Mexico, and you are charged only for days you use the phone abroad. Each session includes 5 GB of high-speed data before speeds drop to 3G. For trips of 9 days or longer, Verizon suggests its $100 International Monthly Plan with 20 GB of high-speed data, unlimited texting and 250 minutes. You can add TravelPass by texting TRAVEL to 4004, and Unlimited Ultimate already includes international service. The math is the issue: 10 days of TravelPass cost $120, while Airalo's 10-day unlimited Europe package is $35.00. Keep TravelPass for one-day stops or for when unlimited calling on your own number matters more than price.
