Travel eSIMs worldwide

All four sell country/region eSIMs but with different pricing models. Airalo is the broad catalogue leader (200+ countries, tiered data plans). Holafly is unlimited-only (good for heavy users, expensive otherwise). Saily is the budget option from the Nord Security team (data plans, no unlimited). Roamic is daily-pass unlimited (good for short trips). Pick by your trip length and data appetite.

Holafly is the unlimited specialist (true unlimited at the cap, tethering allowed in most plans). Roamic sells daily unlimited passes. Airalo and Saily mostly sell metered plans (1GB / 5GB / 10GB tiers).

All recent unlocked iPhones (XR onwards), most Pixel and Samsung Galaxy phones from the last 4 years, and any phone explicitly marketed as eSIM-capable. Older phones, work-locked phones, and many cheaper Androids don't support eSIM. Check your device's settings menu for 'Add Cellular Plan' or 'eSIM' before buying.

Yes — that's the main benefit. The travel eSIM activates as a second line; your home line stays for calls/SMS, the eSIM handles data. Set the travel eSIM as the data line and your home SIM as the call/SMS line.

Install before you fly, but don't activate. Most providers let you install the QR/profile in advance and activate when you land — that's the cleanest flow. Don't activate before leaving home or you'll burn validity days while still on Wi-Fi.
