The nitty gritty
Antigua and Barbuda eSIM FAQs
Traditional calls and SMS aren’t part of our Antigua and Barbuda eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
Of course. You can install your Antigua and Barbuda eSIM up to 30 days before departure. Once you arrive, it will activate automatically.
Installing early won’t use any data or start your plan until you arrive in Antigua and Barbuda.
If your iPhone shows an activation error during pre-install, you can ignore often it - refer to our eSIM Troubleshooting Guide for help.
No - our Antigua and Barbuda 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.
Your eSIM will activate automatically once you arrive in Antigua and Barbuda. We advise installing your Antigua and Barbuda Travel eSIM before you travel (installation is distinct from activation).
To install, just scan the QR code we send or install via the ZenSim app over WiFi. On landing in Antigua and Barbuda, the eSIM will switch on by itself.
If you have any problems, check our eSIM Troubleshooting Guide or contact us 😊
Once you arrive in Antigua and Barbuda, your eSIM activates automatically if it’s already installed.
If you install it after arriving, the eSIM will activate and begin working immediately.

Good question! Opting for a travel eSIM instead of roaming in Antigua and Barbuda offers clear advantages:
Lower Costs: Say goodbye to outrageous roaming bills by switching to a local travel package designed for Antigua and Barbuda.
Seamless Switching: Change between data plans without fumbling with physical SIM cards - perfect for spontaneous travellers.
Budget Control: Track data usage in real time and avoid surprise charges or overages.
No - the plan’s data and days only start when you arrive in Antigua and Barbuda. 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.
Yes - ZenSim’s eSIMs work in 200+ destinations, and Antigua and Barbuda is included. For travellers needing multiple-country access, we offer regional eSIMs. You can find those on our Travel eSIMs page.
Signal & Connectivity: If you’re stuck without data, follow our detailed troubleshooting guide. If issues persist, contact support and we’ll fix it promptly.
Install Assistance: For help installing, consult our installation walkthrough. Still need help? Reach out and we’ll guide you step by step.

Yep! 99% of our eSIMs can be topped up within the ZenSim app with just a couple of clicks. If you run out of data, need more days, or you even want to add a new destination to the same eSIM, you can do all of this in the top up section in the Zen Garden in the app.
Log into the app, navigate to the Zen Garden to find your Antigua and Barbuda service, and you will see a button to up your eSIM right there.
Top up plan options: Antigua and Barbuda top up plans are the same as the plans on the website except with a 10% discount!
Extending a long trip: If you're travelling to Antigua and Barbuda for more than 30 days, you can add as many top ups as you need to your first eSIM to extend the days and data you have. Each top up will only take effect when the previous eSIM is expired so you can purchase the top ups any time you want without worrying about overwriting your existing plan.
Multi country top ups: You can now add multiple countries to most of our eSIMs via top up, so if you're in Europe for example and are stopping over in Dubai on the way home, you can add a Dubai top up to your Europe eSIM so you don't need to reinstall anything. Alternate country top ups will only activate when you arrive in the new country.
Single-country eSIMs like the Antigua and Barbuda 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.
You bet there is! Once you purchase an Antigua and Barbuda eSIM you will be able to access your unique referral URL which you can share with your travel buds.
If they click the URL and purchase a plan they will save A$5 on their order and you will receive a A$5 voucher on your account which will be automatically applied on your next purchase (provided they are a new customer of course).
You can track your referrals and access your referral URL in the ZenSim app. Check out our terms for more info.
Great question! Our Antigua and Barbuda unlimited plans come with a 3GB daily allowance, which is plenty for most travellers - the average person uses under 1GB a day.
If you do blow past that in a single day, your speed drops to 1Mbps until midnight, when your daily allowance resets and you're back to full speed.
If you're on a fixed-data plan instead (say 10GB or 20GB), there's no daily cap at all - use as much as you like until the plan runs out. We'll give you a heads up before that happens, and topping up is just a couple of taps away in the ZenSim app.
Not at all - installing early doesn't use up any of your days or data, and it doesn't set a start date either. Everything stays dormant until you actually land in Antigua and Barbuda.
Once you arrive, and provided you've already installed it, your eSIM activates automatically and your plan's official start date is that moment of arrival.
The end date follows on from there - it'll expire once your data or days run out, whichever happens first (or just the days if you've gone unlimited). A 30-day plan gives you a full 30 days from the moment you land in Antigua and Barbuda, no matter how far in advance you bought or installed it.
Easy way to check - just run your phone through our eSIM compatibility checker and you'll know in seconds whether it'll work with our Antigua and Barbuda eSIM and networks.
Still not sure, or something looks off? Reach out to us and we'll sort it out. And if it turns out your phone genuinely can't run the eSIM, our refund policy has you covered with a full refund - so there's no risk in grabbing a plan and giving it a go.
Yep, that's precisely why we offer a 100% money back guarantee.
Whether it's a cancelled trip, an incompatible phone, or your travel plans simply shifting, you're covered either way.
You'll find the full breakdown in our refund policy, but the gist is: can't install it, can't use it, we'll refund it in full. Simple as that.
