Guam eSIM FAQs
No - the plan’s data and days only start when you arrive in Guam. Installation beforehand simply sets it up for activation on landing.
We recommend installing before departure since you will need WiFi to complete the installation process and this way you will be connected as soon as you land.
If you need help connecting, check our eSIM Troubleshooting Guide or reach out to us.
Your eSIM will activate automatically when you arrive in Guam. Though we recommend installing your Guam Travel eSIM before you arrive (this is different to activating).
To do this, scan the QR code we provide or install the eSIM directly from the ZenSim app while connected to WiFi. Once you arrive in Guam, your eSIM will activate automatically.
If you encounter any issues check out our eSIM Troubleshooting Guide or contact us directly ☺️
If installed before your trip, it will activate when you land in Guam.
If installed after arrival, it goes live right away.
Having issues? Check our eSIM Troubleshooting Guide or contact us for assistance.
No - our Guam travel eSIMs are data - only, so they don’t come with a voice line or phone number. Any calls or texts must go through internet apps like WhatsApp, Telegram, or Viber.
Single-country eSIMs like the Guam one are only valid within that country once activated.
For travel across borders, a regional plan might suit you better - our regional Travel eSIMs cover multiple countries in one.
Most ZenSim eSIMs can be topped up directly inside the app. If you ever need extra data, additional days, or want to include a new destination on the same eSIM, the Zen Garden is where you can do it.
Simply log in, tap into the Zen Garden, and you’ll find the option to top up right there.
Extending your stay: Planning to be away longer than 30 days? You can buy multiple top ups ahead of time. They activate one after another, so there’s no risk of replacing your current plan.
More than one country: Many eSIMs now let you attach extra countries through a top up. For example, while using a Europe eSIM you can add Singapore as an extra destination. It will activate automatically when you land in Singapore.
Connection Problems: If your Guam eSIM isn’t loading data, check our troubleshooting post. If that doesn’t do it, contact us and we’ll get you fixed up.
Installation Questions: Need help installing your eSIM? Visit our how-to guide, or shoot us a message at Contact Us and we’ll sort it out.
Anything Else: Got other queries? Visit our contact page and we’ll be right with you.
Yes - ZenSim’s eSIMs work in 200+ countries, and Guam is included. For travellers needing multiple-country access, we offer regional eSIMs. You can find those on our Travel eSIMs page.
Definitely. Install your Guam travel eSIM up to 30 days before departure, and it will activate automatically when you arrive.
Installing early won’t consume data or days from your plan until you land in Guam.
If an iPhone shows an activation error when installing abroad, you can safely ignore it - check our eSIM Troubleshooting Guide for guidance.
Using a travel eSIM trumps roaming in Guam - here’s a quick rundown:
Significant Savings: Pay local Guam rates instead of exorbitant roaming prices set by your home carrier.
Convenient Switching: No swapping SIM cards - manage everything digitally from your phone settings.
Usage Clarity: Get real-time updates on data consumption, so you never get billed for data you didn’t need.
Traditional calls and SMS aren’t part of our Guam eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.

Top 3 things to do in Guam
Take in the Views from Two Lovers Point
One of Guam’s most famous landmarks, Two Lovers Point, offers breathtaking panoramic views of Tumon Bay and the vast Pacific Ocean.
