Buy. Install.
Travel.
Choose a Horizon plan for your destination, check phone compatibility, install over Wi-Fi, and follow the activation instructions when you travel.
Three steps
Pick a plan.
Browse the live destination catalogue. Compare country plans for one stop, regional plans for neighbouring countries and global plans for wider routes.
Install before you travel.
On a compatible, carrier-unlocked phone, scan the QR code or use direct installation when offered. Many dual-SIM phones can keep the home line alongside the Horizon eSIM, but line behavior depends on the device and settings.
Land. Connect. Go.
At your destination, follow the selected plan’s activation instructions. The plan details shown before purchase explain when validity begins.
A practical trip checklist
Check the phone, the route and the activation rule before paying.
An eSIM is convenient, but it is still a plan for a specific device and trip. A few checks before checkout reduce the risk of common problems: an unsupported regional model, a carrier lock, a destination missing from a multi-country plan or validity starting earlier than expected.
Before you choose a plan
Use the device you will carry—not a similar model—as the reference for every check.
- Confirm the exact model and sales region. eSIM support can differ between versions sold under the same phone name. Match the model number to the supported-device guidance.
- Check that the phone is carrier-unlocked. An eSIM-capable phone may still reject another provider’s profile when it is locked to a home carrier.
- Plan for reliable Wi-Fi. Download the profile before departure when the plan instructions permit it, but do not trigger activation early.
- Read the listing, not only the plan name. Check included destinations, allowance, validity, networks, activation trigger and any tethering or top-up notes.
Country, regional or global?
Choose from the actual itinerary. A wider label is useful only when the selected plan lists every stop you need.
Country plan
Usually the clearest fit for one destination. It does not automatically cover a border crossing, airport connection or neighbouring country.
Regional plan
Useful for several listed countries in one region. Compare its exact destination list and price with separate country plans.
Global plan
Designed for a wider multi-continent route. “Global” is not a promise of every country, so verify every stop in the live listing.
From confirmation email to working data
Keep the order instructions available offline and treat installation, activation and data-line selection as separate steps.
- 01
Review the order
Confirm the destination, allowance and validity. Save the receipt and secure order link somewhere you can reach without mobile data.
- 02
Install the profile
Use the QR code, tap-to-install link or manual details over Wi-Fi. Label the new line clearly and keep your home SIM settings unchanged for now.
- 03
Follow the arrival settings
Select the Horizon line for mobile data and follow that plan’s data-roaming and activation instructions. Disable home-line data switching if it could create roaming charges.
- 04
Test before deleting anything
Wait for network registration, then test a webpage. If data fails, review the selected line, roaming and APN guidance; do not delete the eSIM unless instructed.
Treat the QR code like a credential
Do not publish or casually forward the QR code, SM-DP+ address, activation code or secure order link. An eSIM profile is normally intended for one compatible device, and deleting or moving it may not be reversible.
The five things people always ask.
Can I keep my home phone number?
Often, if your unlocked phone supports dual SIM. Choose the Horizon eSIM for mobile data and set your home line for calls or SMS only if that is what you want. Device menus vary, and your home carrier may charge for roaming calls, texts or data, so check its settings and rates.
Will my phone work in every country?
Each Horizon plan lists its supported destinations and networks. Compatibility also depends on the exact phone model, sales region and carrier lock, so check both before purchase.
What if I delete the eSIM by accident?
Do not delete the profile unless the plan instructions or support team tell you to. If it was removed, contact support before attempting another installation.
Can I top up an existing plan?
Open My eSIMs and check whether the package offers a top-up. Availability, added data and validity depend on the plan.
Can I use the same eSIM on more than one device?
An eSIM profile is normally installed on one compatible device at a time. Reinstallation or transfer depends on the device, provider and selected plan, so do not delete the profile unless the plan instructions say it can be restored. For simultaneous use on two devices, buy a separate plan for each.
Ready when you are.
Find a plan for your next trip, review its coverage and validity, then set it up on a compatible phone before departure.
