FREQUENTLY ASKED QUESTIONS
An eSIM (embedded SIM) is a digital SIM built into your device — there's nothing to insert or swap. You buy a plan, scan a QR code or tap an install link, and you're connected in minutes, without hunting for a local SIM shop or waiting for a card to arrive in the mail.
Most smartphones released in the last few years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Check your device settings under Settings > General > About (iPhone) or Settings > Network & Internet (Android) for "eSIM" or "Add eSIM," or see our full compatibility list before purchasing.
