What is an eSIM top-up?
An eSIM top-up adds a data plan to an existing, supported eSIM profile. Keep that profile installed on your phone: a supported refill does not require a new QR code. Availability, coverage and activation depend on the plan and the eSIM you select.
Built around your trip
One installed profile. Your next plan.
Keep your setup
A supported top-up goes onto the eSIM already installed on your phone. You can leave its label and settings in place.
Choose where you go next
Use Top up for the same destination or Add country for another supported destination. Review coverage before choosing.
Review the details first
Check data allowance, validity, total price and the target eSIM before payment. Your order records the plan you selected.
How to top up your eSIM
From your eSIM card to your next plan
Find your installed eSIM
Open My eSIMs and match the card to the profile on this phone. Check its last digits, especially if you manage several eSIMs.
Choose your destination
Select Top up or Add country where offered. Pick a plan with the coverage, data and validity your trip needs.
Review and pay
Confirm the target eSIM and total price. Complete the hosted payment flow and any bank approval, then return to Horizon.
Check your new plan
Wait for the order to finish and check the added plan on your eSIM. Keep roaming enabled and follow that plan’s activation rules.
Check that your eSIM supports top-ups
My eSIMs shows the actions available for each profile. Another provider’s eSIM cannot receive a Horizon top-up. Buying a new eSIM and adding a plan to an existing one are different choices.
Top-ups for existing Kosovo eSIMs are unavailable. Their balance and history remain visible; buying a new Kosovo eSIM is a separate purchase.
Keep your profile installed. A top-up does not reinstall a deleted profile, move it to another phone or restore a disabled eSIM. Ask support if the profile is missing.
When ordinary data runs out
Connect, then add your next plan
Connect to Wi-Fi or use another data connection to open Horizon, sign in and add a plan. Keep your existing eSIM installed while you arrange the refill. An exhausted allowance does not mean you need to delete the profile.
Sign-in services and bank approval pages may need Wi-Fi or another connection, even when Horizon itself opens.
Open refill pageFinish one payment before starting another
Checkout uses Paysera or its card payment gateway. Available methods appear on the hosted payment page; your bank may request additional approval. Return to Horizon to check the order and plan status.
If the page stalls or the order remains pending, check the existing order before trying again. Do not start a second payment while the first is unresolved. Use another connection or contact support with the order reference.
eSIM top-up questions
Can I add more data to my existing eSIM?
Yes, when your Horizon eSIM supports it. Open My eSIMs and use the available Top up or Add country action. Review the target profile before paying.
Do I need a new QR code for a top-up?
A supported top-up uses the installed profile, so no new QR code is needed. Keep the profile installed. A new eSIM purchase has its own installation instructions.
Can I add another country to the same eSIM?
Use Add country where offered on your eSIM card. Only compatible destinations and plans are available. A country top-up does not automatically cover every country on your itinerary.
Can I top up after my data runs out?
Yes, if your eSIM supports top-ups. Connect to Wi-Fi or use another data connection, open My eSIMs and choose a plan. Keep the profile installed throughout.
Can I top up completely offline?
No. Buying a plan needs a working connection. Recovery access, where enabled, still needs a supported mobile network and reachable sign-in and payment pages. With no mobile signal and no Wi-Fi, reconnect before buying a plan.
When does my new plan start?
The selected plan’s activation rules apply. Check its details before purchase and its status after the order finishes. Adding a plan does not mean every plan activates immediately.
Can I refill an expired plan or a deleted eSIM?
A used-up or expired plan can remain in your history while an installed, supported profile receives another plan. A deleted or disabled profile is different: a top-up does not restore it.
Can I top up my existing Kosovo eSIM?
Top-ups for existing Kosovo eSIMs are unavailable. You can still view their balance and history. A new Kosovo eSIM, when available in the store, is a separate purchase and installation.
What should I do if my top-up payment is pending?
Open the existing order and check its status. Do not submit another payment while it is unresolved. If you need help, contact Horizon support with the order reference.
Start with the eSIM already on your phone
Open its card, check the available actions and choose your next plan.
