Set up a Nigeria eSIM on reliable Wi-Fi before departure, but leave its line disabled until you are in Nigeria. First confirm that the exact phone supports eSIM and is not carrier-locked. Installation does not consume the selected validity: the first successful connection to a supported network in the included destination starts it.
Check the phone before buying
Use Horizon’s supported-device guide for the model and regional version you actually own. Apple’s travel eSIM guidance also explains why eSIM capability, carrier lock and the selected mobile-data line matter on an iPhone. Android menus vary, so follow the instructions for your device instead of copying labels from another phone.
A Horizon Nigeria plan is data-only and does not include a Nigerian phone number. A compatible dual-SIM phone can keep the home SIM installed for calls or messages, but the home provider may charge for any service left active abroad.
Install before departure
Follow the Horizon installation guide while dependable Wi-Fi is available. Add the profile, give it a clear label, and retain the QR code or manual setup details somewhere you can reach without mobile data. Keep the Horizon line off until Nigeria. Also save the first accommodation address, booking reference and organiser contact offline.
Prepare Lagos or Abuja separately
The Federal Airports Authority of Nigeria lists Murtala Muhammed airport in Ikeja/Lagos and Nnamdi Azikiwe airport in Abuja as distinct facilities in its airport contacts. For Lagos, note the terminal in the flight booking and the final neighbourhood, such as Ikeja, Victoria Island, Lagos Island or Lekki. For Abuja, keep its own airport, meeting point and stay address together. If the trip continues elsewhere, confirm that next stage on its own booking; a through-ticketed journey may still have precise meeting details.
Turn on the line in Nigeria
Once you are in the included destination, select Horizon as the mobile-data line and enable data roaming on that line. Keep data switching to the home SIM off unless you deliberately accept its provider’s charges. The eSIM’s first successful connection to a supported network in Nigeria starts the selected validity. Test a simple page or message, then open the saved arrival details you need.
Hotspot sharing is free on every Horizon plan, and Horizon does not throttle hotspot use. The phone and connected devices share one plan allowance, so include laptop work when choosing data. The method in how much data to plan for Nigeria helps with that choice.
If the connection needs attention
Recheck that Horizon is selected for mobile data, roaming is enabled on that line, and the home line has not taken over data. Use the saved installation instructions rather than inventing an APN. If the problem remains, contact Horizon support with the order details and device model.
Four quick answers
- Can I install early? Yes. Keep the line disabled; its first successful connection to a supported network in Nigeria starts validity.
- Can I keep my number? Yes on a compatible dual-SIM phone, subject to charges from the home provider.
- Does it give me a Nigerian number? No. It supplies mobile data for internet calls and messaging apps.
- Does the Africa package cover Nigeria? Horizon’s current package does not. Read the Africa coverage explanation before combining countries.
Choose the plan for the actual stay
Compare the live Nigeria plans by data and validity rather than assuming one size fits every visit. If its amount and duration suit your complete trip, review the Nigeria 10 GB, 30-day option alongside the other plans shown.
