Guac - Travel eSIM

You just landed. No WiFi. No local SIM shop in sight. Your carrier wants $15/MB for roaming.

Sound familiar?

Guac fixes this. Buy an eSIM data plan before your flight, activate it in seconds, and walk off the plane with data already working. No plastic SIM cards. No airport kiosks. No roaming horror stories.

NEW: YOUR OWN NUMBER AND CALLS

Guac isn't just data anymore. Rent a real phone number right in the app, then make and receive calls from anywhere. Keep your home SIM for banking and 2FA, and use Guac for everything else. Pay as you go from your wallet, top up when you want, no subscription.

190+ COUNTRIES. ONE APP.

Whether you're hopping between hostels in Southeast Asia, taking calls from a coworking space in Lisbon, or navigating Tokyo's metro system, Guac has you covered. Pick a country plan, a regional plan, or go global with a single eSIM that works in 125+ countries.

BUILT FOR HOW YOU TRAVEL

Instant setup: Buy, install, and activate your eSIM before boarding. Under 2 minutes.
