Use a Senegal eSIM for data during a Dakar stay, a booked transfer to Saly or Somone, or a Saint-Louis visit with a separately organised delta day.
For a Gorée or Ngor outing, retain the city lodging, the booked meeting point and the return arrangement without assuming data during the crossing. A Petite Côte stay should name Saly Portudal or Somone and the actual hotel entrance. Farther north, a Saint-Louis address does not identify the guide or meeting place for Djoudj National Park or a Senegal River delta visit.
Refund policy
We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.

Install the eSIM on dependable Wi-Fi before travel and save the QR code and instructions separately. Keep the line disabled until Senegal, then select Horizon for mobile data and enable data roaming on that line. For this Senegal product, the first successful connection to a supported network in Senegal starts the selected validity period. Store transfer, island-day and delta contacts offline before leaving your accommodation.

Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
In total, a 3 GB data allowance covers roughly 1,000 shared photos, 50 hours of social media and browsing, 8.8 hours of video calls, 38 hours of music streaming, or about 600 hours of maps and navigation. Messaging apps barely use data.
Dakar · City guide
A Dakar day can combine museums, markets or the railway-station area with a booked Gorée or Ngor outing. Keep the land-based meeting point and organiser updates available, and save how you will return to the city.
Dakar eSIM — set up before you flySaly and Somone · City guide
Saly Portudal and Somone are separate coastal places, so a general Dakar address is not enough for the final transfer. Save the exact accommodation entrance and pickup contact.
Saly and Somone eSIM — set up before you flySaint-Louis and the delta · City guide
Saint-Louis is a northern city base linked by the Faidherbe Bridge, while Djoudj National Park and Senegal River delta visits require their own arrangements. Save the guide’s name, meeting place and return contact before departure.
Saint-Louis and the delta eSIM — set up before you flyWhy Horizon
Preparing an eSIM before travel keeps the Senegal data line ready for organiser messages, maps and internet calls between booked stages. Hotspot is free on every Horizon plan, and Horizon does not throttle its use; the phone and connected devices share one plan allowance. The service is data-only and includes no local number. A compatible dual-SIM phone can retain your home line, although its provider may charge for calls, messages or roaming.

Senegal
Compare the listed data allowances and validity periods for your destination.
Install over reliable Wi-Fi before departure and follow the plan's activation instructions.
Review the current price, data, validity and coverage before checkout. Horizon fixed-data plans have no throttling.
When the selected plan supports reuse or top-ups, My eSIMs shows the eligible options for the installed profile.
We'll alert you as you approach your limit. If the plan supports a top-up, My eSIMs shows the eligible options.
Choose country, regional or global coverage and check every destination in the plan details.
Saly Portudal and Somone are distinct Petite Côte locations, not Dakar neighbourhoods. Save the exact town, hotel entrance and driver or host contact before arrival rather than sending only a Dakar pin.
Keep the booked meeting point on land, organiser contact, any ticket reference and the planned return to Dakar. Confirm the crossing arrangements with your organiser and save the details offline before leaving land.
Save the Saint-Louis lodging and old-city address separately from the Djoudj or river meeting place. Keep the guide’s name and return contact available offline.
No border crossing is included by geography alone. A Senegal country plan lists Senegal, and Senegal is outside Horizon’s current Africa regional package. Check The Gambia or Mauritania explicitly in the product details for a route that enters either country.
The Horizon eSIM is data-only and does not include a local number. On a compatible dual-SIM device, keep your usual SIM enabled for its number and select Horizon for mobile data. Your home provider may charge for calls, texts or roaming on that usual line.
The first successful connection to a supported network in Senegal starts this product’s selected validity; installation or an unsuccessful attempt does not. Hotspot is free and not throttled by Horizon. Your phone and all connected devices use one shared plan allowance, so count their combined tasks when choosing data.
No. Horizon plans are data-only, with no phone number for calls or texts. Use apps such as WhatsApp or FaceTime over the eSIM's data, or keep your usual SIM on for ordinary calls and texts.
Yes. A travel eSIM connects to local networks as a roaming line, so turn on data roaming for the Horizon eSIM when you arrive. The plan is prepaid, so Horizon does not bill you after checkout. Keep data roaming off on your usual SIM to avoid charges from your home carrier.
You can buy more. If your plan supports a top-up, My eSIMs shows the data you can add to the same eSIM. If it does not, buy another Senegal plan and install it the same way.
It will if your phone supports eSIM and is not locked to your home carrier. Many recent iPhone and Android models do, but some regional versions do not, so check your exact model on the supported devices page before you buy.
See supported devicesNo. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
