Guac - Travel eSIM

Mobile Internet for Travel

Free · Designed for iPad. Not verified for macOS.

Land, connect, done. eSIM data in 190+ countries, your own number for calls, and 5% back on everything. Your carrier will be fine without you. 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. Calls: Rent a number, then call from inside the app. Real lock-screen call experience, not a clunky workaround. Top up on the go: Running low on data? Add more to your active eSIM up to 10 times. Share with your crew: Send a spare eSIM to a friend with a single link. They tap, they claim, they're connected. Smart data calculator: Tell us your trip and we'll recommend the right plan. Real-time tracking: Alerts at 20%, 50%, 80%, and 90% so you're never caught off guard. Home screen widget: Check your eSIM status without opening the app. EARN WHILE YOU TRAVEL Every purchase earns you 5% back in Guac Credit, usable as credit toward your next plan. PAY YOUR WAY Apple Pay or card. Multi-currency pricing. No hidden fees, no auto-renewals. Stop overpaying for roaming. Stop hunting for SIM cards. Now stop juggling phone numbers too. Guac.

Referral codes Fixed an issue where a referral code entered at checkout on a new install was rejected as invalid. Calling More reliable call setup, and clearer messages when a call cannot connect. Plus a range of smaller fixes and improvements throughout the app.
