Got questions?
Here's the answers.
An eSIM is a digital SIM embedded in your phone - no physical card needed. With Guac, you browse data plans for your destination, purchase one, and activate it instantly. Your eSIM connects to a local network so you get fast, affordable data wherever you travel.
After purchasing a plan, Guac activates your eSIM automatically with one tap. No QR code scanning required. Just make sure you have an internet connection (Wi-Fi or existing cellular) during activation.
Most modern smartphones support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3a and later, and many more. You can check device compatibility in the Guac app before purchasing.
Yes! Guac lets you purchase an eSIM as a gift and share it via a link. The recipient can activate it on their own device - perfect for travel companions.
Your data plan duration starts when you first connect to a mobile network at your destination, not when you purchase or install the eSIM. So you can buy ahead of your trip without worrying about wasted days.
No. Your eSIM works alongside your physical SIM. You can keep your home number active for calls and SMS while using the Guac eSIM for data.
You'll receive a notification when your data is running low. You can easily top up or purchase a new plan directly in the Guac app - no new eSIM installation needed.
Guac eSIMs connect to land-based cellular networks, so they won't work while at sea. However, they're perfect for your port stops! Our Regional and Global plans cover multiple countries with a single eSIM, making them ideal for multi-port cruises. For example, a Europe plan covers over 40 countries for Mediterranean cruises.
Take Guac with you
Everything you buy here is waiting in the app - your eSIMs, your wallet, your number. Scan the code or grab it from the store.
