Travel eSIM Sri Lanka

These eSIMs don’t include voice minutes - data only. For any calling or texting, you’ll need to rely on VoIP or messaging apps such as WhatsApp, Viber, or Messenger.

Yes! Your Sri Lanka eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Sri Lanka.

Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.

If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.

Our Sri Lanka travel eSIM is strictly for data; it doesn’t come with a phone number or traditional call/SMS service. Use an internet calling app if you need voice communication.

Your eSIM will activate automatically when you arrive in Sri Lanka. We recommend installing your Sri Lanka Travel eSIM in advance (installation is different from activation).

Just scan the QR code you receive or install via the ZenSim app using WiFi. Once you touch down in Sri Lanka, your eSIM will go live automatically.

If anything goes wrong, check out our eSIM Troubleshooting Guide or contact us 😊

Your Sri Lanka eSIM will start working the moment you land in Sri Lanka-it auto-activates if installed prior to departure.

If you install it after arrival, it will connect immediately.

Absolutely - using a travel eSIM beats roaming in Sri Lanka for several reasons:

Cost Efficiency: Our Sri Lanka local data rates are much cheaper than pay-as-you-go roaming fees.

Instant Activation: No need to wait for a SIM card; your eSIM goes live as soon as you land.

Data Visibility: Monitor exactly how much you’ve consumed, so there are no hidden surprises on your bill.

Not until you land in Sri Lanka. Installing ahead won’t start your plan; it goes live automatically when you arrive.

Make sure to install before you travel, as WiFi is required for setup and this way your Sri Lanka eSIM will be ready to use when you land.

If you encounter connection issues, see our eSIM Troubleshooting Guide or contact support.

Of course! At ZenSim, we offer eSIMs that support over 200+ destinations, including Sri Lanka. On top of this we also provide regional eSIMs which cover multiple countries within one eSIM, please see our Travel eSIMs page for more info on these.

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 Sri Lanka service, and you will see a button to up your eSIM right there.

Top up plan options: Sri Lanka 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 Sri Lanka 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.

After activation in Sri Lanka, your eSIM won’t usually work elsewhere. Each country typically needs its own eSIM unless you're using a regional one.

To make travel easier, try one of our regional Travel eSIMs - they work across entire continents.

Yep, you can, can you should! For every friend or family member you refer to purchase a Sri Lanka eSIM, you will earn a A$5 voucher to use on your next purchase AND they will save A$5 on their purchase.

All you have to do is share your unique referral URL with them, which you can access after purchase, and if they click it and purchase the savings are automatic.

You can monitor your referrals and find your personal referral URL directly in the ZenSim app. Read our terms for full details.

Only on unlimited plans, and only past 3GB in a single day - which is a generous amount, considering most travellers use less than 1GB daily.

If you do go past 3GB, your speed will be limited to 1Mbps until midnight, when it resets and you're back to full speed again.

Fixed-data plans (10GB, 20GB, etc.) don't have any daily throttling - you're free to use your data at whatever pace suits you until the plan's used up. We'll flag it before you run out, and topping up takes just a couple of taps in the ZenSim app.

Your days and data don't start counting down the second you buy the eSIM - they only kick in once you actually land in Sri Lanka, so feel free to install it well ahead of your trip.

As long as it's already installed, it'll auto-activate the moment you arrive, and that's when the clock starts on your plan.

As for when it ends - your plan runs until either your data or your days are used up, whichever happens first (unless you're unlimited, in which case it's just the days that matter). A 30-day plan means it ends 30 days from your arrival in Sri Lanka, not 30 days from your purchase date.

Definitely - our eSIM compatibility checker is built exactly for this. Punch in your phone details and you'll get an instant answer on whether it works with our Sri Lanka eSIM and networks.

Want a second opinion, or something seems off? Message us and we'll help you out. And even if you do end up buying and it turns out your phone can't use it, our refund policy means a full refund - so there's genuinely no downside to trying.

Absolutely - that's exactly what our 100% money back guarantee is there for.

Whether your trip gets cancelled, your phone turns out not to be eSIM-compatible, or your plans just change and you can't use it anymore, you're covered.

All the details live in our refund policy, but the short version is simple: if you can't install or use the eSIM, we'll refund you in full. Nobody should pay for a plan they can't use.
