Best eSIM for Senegal 2026
Senegal is one of the few countries in this whole series where the math never flips: checked against Siima's own live prices, a worldwide eSIM plan beats the Senegal-only one at every data tier, not just the small ones. Here's the actual price table, which network you'll land on, and what a local SIM counter asks for that an eSIM skips entirely.
Orange vs Yas vs Expresso
Orange, operating locally as Sonatel, is Senegal's dominant carrier by a wide margin — roughly 13.6 million active connections as of December 2025 and a market share generally put around 56%. Yas is the newer name for what used to be Free Senegal; it rebranded in 2024 under Madagascar-based Axian Group, which holds an 80% stake, and runs a clear second with about 5.6 million connections, somewhere in the low-to-mid 20s percent of the market. Expresso trails both and is losing ground fast — its subscriber base fell about 12% in 2025 alone, against overall market growth of 4.4% — leaving it the weakest of the three by a growing margin.
| Network | Profile | Best for |
|---|---|---|
| Orange (Sonatel) | Dominant leader, ~56% share, roughly 13.6M connections; first to launch commercial 5G in the country. | Everywhere, especially outside Dakar |
| Yas (formerly Free) | Clear second, ~5.6M connections, 80%-owned by Axian Group since its 2024 rebrand; also holds a 5G concession. | Dakar and the larger regional towns |
| Expresso | Smallest of the three and shrinking — lost about 12% of its subscriber base in 2025. | Dakar as a backup only |
Orange won Senegal's first 5G concession in July 2023 and switched on fixed 5G in March 2024, mobile 5G that July — the earliest commercial rollout in the country. Yas holds a 5G concession of its own, though its mobile build hasn't matched Orange's head start yet. None of this changes which network your eSIM lands on once you touch down — Siima's roaming partner picks automatically — but it explains why Orange is the name you'll see on your phone almost everywhere in the country, Dakar included.
The worldwide plan wins at every tier — no exceptions
Most guides in this series land on a crossover point, where a single-country plan starts cheaper once you buy enough data. Senegal doesn't have one. Checked against Siima's live catalogue, the worldwide plan comes in cheaper than the Senegal-only plan at every single data tier it offers.
| Plan size | Senegal-only | Worldwide (104 countries) | Cheaper option |
|---|---|---|---|
| 1GB / 7 days | $19.16 | $13.06 | Worldwide |
| 2GB / 15 days | $36.60 | $24.82 | Worldwide |
| 3GB / 30 days | $51.06 | $34.58 | Worldwide |
| 5GB / 30 days | $83.98 | $56.79 | Worldwide |
| 10GB / 30 days | $153.81 | $103.90 | Worldwide |
| 20GB / 30 days | $276.00 | $186.34 | Worldwide |
The gap doesn't close as the plans get bigger, either — it widens, from about $6 at the 1GB tier to roughly $90 by 20GB. The practical upside goes beyond price: a worldwide eSIM keeps working if your trip connects through Casablanca, Paris or Istanbul on the way in or out, which a Senegal-only plan obviously won't. Siima doesn't currently sell a West Africa regional plan, so worldwide is the only multi-country option today if the Senegal-only plan's price alone isn't reason enough to skip it.
A local SIM wants your passport. A travel eSIM doesn't.
Senegal's 2018 Electronic Communications Code requires every mobile subscriber to be identified at the point of sale — a national ID card or passport, checked in person, with a notarized power of attorney if someone else is buying on your behalf. The regulator, ARTP, pushed operators and their distributors to tighten enforcement of this after finding lax compliance at the counter in January 2025, and subscribers are capped at three SIM cards per operator. None of that is aimed at tourists specifically, but it's still a counter, a document check and a wait that a prepaid SIM purchase in Senegal involves.
A Senegal eSIM skips all of it — it's tied to your Siima order before you fly and live the moment you land at Blaise Diagne International.
Coverage by destination
How much data do you need in Senegal?
Most Senegal trips center on Dakar with a side trip north to Saint-Louis or south into the Sine-Saloum, with data use concentrated in towns and lighter on the roads between them.
| Trip type | Recommended data |
|---|---|
| Long weekend in Dakar and Gorée Island | 1 GB |
| A week: Dakar plus Saint-Louis or Sine-Saloum | 2–3 GB |
| Dakar, Lac Rose and Saint-Louis combined | 3–4 GB |
| Add a Casamance extension | +1 GB |
| Two-plus weeks covering the whole country | 5–8 GB |
The US State Department rates Senegal Level 1, "Exercise Normal Precautions," nationally — the exception is Casamance, rated Level 2 for crime and landmines left over from a long-running separatist conflict, with the advisory noting mines are often unmarked in border and rural areas. The usual advice applies if a trip heads south of Ziguinchor: stick to main roads, travel by day, and skip anywhere a local guide flags as unmarked ground.
