Traveling is stressful enough without the added joy of fiddling with SIM cards and setting up data service in foreign countries. Enter Saily Ultra, a top-tier eSIM service that covers 121 countries, is packed with perks, and aims to keep you connected wherever you roam. The catch? The Premium plan will set you back $60 per month - because of course it will. This plan is aimed squarely at jet-setters and will likely best suit business travelers or folks embarking on a multicountry tour, i.e., people who have better things to do than argue with a foreign SIM card.

An international eSIM service can be set up on your phone before you even leave home, and it will connect you with local networks the moment you land. If you have a phone with dual eSIM support, like the iPhone 16 we tested Saily Ultra with, you can keep your regular number and add a second one for your international trip, or just use the international eSIM for mobile data. Because nothing says 'vacation' like having two phone numbers, right?

Most of us have been stung by painfully expensive roaming charges at some point. While it’s worth checking what kind of international service options your usual provider offers, a separate international eSIM service can make life easier and keep costs transparent. Saily Ultra comes in three tiers, all covering the same 121 countries and offering the same perks - so you can pay more for the privilege of not thinking about which tier you're on.
