About this app
Travel data without the roaming bill. Horizon eSIM gives you prepaid mobile data in 190+ destinations — delivered to the app minutes after checkout, ready before you land.
Browse country, regional and global data plans with the data allowance, validity, supported networks and exact EUR total shown before you pay. No contracts, no hidden fees, no plastic SIM — and on dual-SIM phones your own number stays active for calls, texts and WhatsApp.
Popular destinations
Europe, Turkey, USA, United Kingdom, Germany, France, Switzerland, Japan, South Korea, Australia, the Balkans and many more.
Compare plans for your trip

Install your eSIM
On supported phones, use one-tap installation. You can also scan the QR code from another screen or copy the manual SM-DP+ address and activation code. Your phone must support eSIM and be carrier-unlocked.
Manage everything in the app
• Track eSIM status, data usage, allowance and validity in My eSIMs. Usage reporting can be delayed.
• Get usage alerts before you run out.
• Top up or add another destination mid-trip when the package supports it.
• Family & friends: buy plans and assign them to the people you travel with.
• View orders and receipts, and open setup help any time.
Current catalogue details
Horizon does not own mobile network infrastructure. eSIM plans come through connectivity providers that work with local carriers. Coverage, speed, network technology, hotspot access, activation timing, fair-use rules and top-up availability depend on the selected package, phone, local network, congestion and location. Prices and availability can change — review the package and exact checkout total before payment. A regional or global eSIM covers only the destinations named in its coverage list.
Payment and delivery
Payment is handled by the provider shown at checkout. Horizon receives a transaction reference but does not store your full card number, CVV or PIN. After confirmed payment, eSIM installation details appear in the app and are sent to the email address used for the order.
Before you buy
• Confirm that your phone supports eSIM and is carrier-unlocked.
• Check the package's destinations and networks.
• Review when validity starts and any first-use deadline.
• Read fair-use rules for day-pass or unlimited-labelled packages.
• Check whether hotspot and top-ups are supported.
• Read the refund policy before installation or activation.
A travel eSIM adds a data-only line to a compatible phone — Horizon plans include no phone number, voice calls or SMS. On a dual-SIM phone you can usually keep your main SIM enabled for calls and texts while the eSIM carries your data. Your home carrier may charge for roaming activity, so check its terms before travel.
Help and support
Real people on WhatsApp and email — before, during and after your trip. Open Help in the app for device setup, installation guidance and troubleshooting.
