Senegal is straightforward on the coast and in Dakar, and gets patchier as you move inland or south into the Casamance. Orange has by far the widest reach, and most travel eSIMs route through it.
Senegal's mobile networks
Orange Senegal (Sonatel) is dominant with the widest national coverage, including most of the interior and the Casamance.
Free Senegal (formerly Tigo) is a strong second, good in Dakar and along the coast.
Expresso is the smallest, mainly urban.
For anything beyond Dakar and the Petite Côte, Orange is the network you want behind your plan.
Coverage, region by region
Dakar — Strong 4G across the peninsula, with 5G in parts of Plateau, Almadies and Ngor. Good coverage on Île de Gorée and the ferry crossing.
Saly and the Petite Côte — Comprehensive. This is the package-holiday coast and it's well served throughout, including Somone and Popenguine.
Saint-Louis — Solid in the town and on the island. Weaker heading into the Langue de Barbarie.
Lac Rose (Lake Retba) — Coverage around the lake and the main access roads.
Sine-Saloum Delta — Patchy. Signal in the larger villages like Ndangane and Palmarin, much less out on the water and in the mangrove channels. Boat excursions will drop out.
Casamance (Ziguinchor, Cap Skirring) — Reasonable in Ziguinchor and around Cap Skirring's hotels. The rural areas between are thin, and the ferry from Dakar loses signal for stretches at sea.
Niokolo-Koba National Park — Very limited. Expect little to nothing on game drives.
Touba and the interior — Coverage in the towns, gaps between them.
Podor and the Senegal River valley — Basic coverage in the settlements, unreliable elsewhere.
How much data do you need?
| Trip length | Light use | Typical use | Heavy use |
|---|---|---|---|
| One week | 1–2 GB | 3 GB | 5 GB |
| Two weeks | 3 GB | 5 GB | 10 GB |
| One month | 5 GB | 10 GB | 20 GB |
"Typical" covers maps, WhatsApp, email, social media and photo sharing. See how much data you actually need for a fuller breakdown.
Setting up before you fly
Install at home on Wi-Fi a day or two before you leave. The profile downloads then; the plan generally starts counting when it connects to a Senegalese network.
- 1Buy your plan and receive the QR code by email
- 2Scan it — Settings → Cellular → Add eSIM on iPhone
- 3Label the line "Senegal"
- 4Leave it switched off until you land
- 5At Blaise Diagne, enable the line and turn Data Roaming on for that line specifically
Data Roaming must be on for the travel eSIM and off for your home carrier line.

Practical tips for Senegal
- The airport is well outside Dakar. Blaise Diagne is roughly an hour from the city, so having data active on landing makes arranging transport considerably easier.
- Download offline maps for the Sine-Saloum and Casamance. Both have real gaps and both involve boats.
- WhatsApp is the standard channel for guides, drivers and guesthouses.
- French is the working language for most services — download offline translation before you go if that's a barrier.
- Check your phone is unlocked: Settings → General → About → Carrier Lock should read "No SIM restrictions". See which iPhones have eSIM.
- Keep your home line on for two-factor codes. iPhone 13 and newer run both at once — see the dual SIM guide.
- Heading to The Gambia too? A Senegal-only plan stops at the border. Check whether a West Africa regional plan covers both before buying twice.

FAQ
Does eSIM work in Senegal? Yes. Travel eSIMs work in Senegal and typically route through Orange Senegal, which has the widest national coverage. Your phone must be eSIM-capable and carrier-unlocked.
What is the best eSIM for Senegal? For Dakar and the Petite Côte, any major network works well, so compare on price per gigabyte. If you are travelling inland or into the Casamance, choose a plan routing through Orange.
Is there coverage in the Casamance? Reasonable in Ziguinchor and around Cap Skirring, thinner in the rural areas between. The ferry from Dakar loses signal for stretches at sea.
How much data do I need for a week in Senegal? Around 3 GB covers typical use — maps, WhatsApp, email and social media. Light users manage on 1–2 GB.
Can I use a Senegal eSIM in The Gambia? No, not with a Senegal-only plan. If your trip crosses into The Gambia, check whether a West Africa regional plan covers both countries.
Is there mobile signal in the Sine-Saloum Delta? Patchy. There is signal in larger villages such as Ndangane and Palmarin, but boat excursions through the mangrove channels will lose it.
