## What Is Guac?

Guac is a travel data service that sells eSIM plans for international travelers. An eSIM is a digital SIM embedded in your phone. Instead of buying a local SIM card at the airport or paying roaming fees, you purchase a data plan from Guac and activate it instantly on your device.

Guac covers 200+ countries with plans starting from $1.50/GB. Every purchase earns 5% cashback that can be applied to future plans. You can also buy an eSIM as a gift and share it with a travel companion via a link.

## How It Works

1. Browse plans: Visit guac.online/destinations or open the Guac app and search for your destination country or region.
2. Choose a plan: Select a data package based on how much data you need and your trip duration. Plans range from 1 GB for a few days to unlimited data for up to 180 days.
3. Purchase: Pay with card or Apple Pay. There are no hidden fees or activation charges.
4. Activate: Your eSIM activates automatically with one tap. No QR code scanning required. Just make sure you have an internet connection (Wi-Fi or existing cellular) during activation.
5. Travel: Your eSIM connects to a local carrier network at your destination. Your home number stays active on your physical SIM for calls and texts.
6. Top up: If you need more data, top up directly in the app without installing a new eSIM.
