eSIM guide
What is an eSIM?
An eSIM is a digital SIM built into your phone. Instead of inserting a plastic card, you download a mobile plan and connect in minutes — ideal for travel.
A SIM without the plastic
Traditional SIM cards are physical chips you swap in and out of your phone. An eSIM (embedded SIM) is software-based profile installed on a compatible device. That means you can add a local or regional travel plan without visiting a store or waiting for a card in the mail.
With AeroSIM, you buy a plan for your destination, receive a QR code instantly, and install it before you fly — so you can go online as soon as you land.
Why travelers use eSIM
eSIMs are built for people who move between countries and want reliable data without expensive roaming from their home carrier.
- Instant digital delivery — no shipping, no airport kiosk queues.
- Keep your primary number for calls and messages while using travel data on the eSIM.
- Switch plans by destination without changing hardware.
- Works on most recent iPhones, Google Pixels, and many Android flagships.
eSIM vs physical SIM vs roaming
Physical local SIMs still work, but they usually mean finding a shop, showing ID, and swapping cards. Carrier roaming is convenient, but daily rates add up quickly.
An AeroSIM travel eSIM sits in the middle: buy online, install in minutes, and pay for a data package sized to your trip.
What you need
To use AeroSIM you need an unlocked, eSIM-compatible phone and a Wi-Fi connection for installation. After install, your plan activates according to the product rules — typically when you first connect to a supported network at your destination.
