What a Retba Mobile eSIM costs
The cheapest published plan on the Senegal travel eSIM is $6.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $11.00, a 3 GB / 30 day plan is $15.50, a 5 GB / 30 day plan is $25.00, and 10 GB over 30 days is $45.00. There is no unlimited SKU on this product. The 3 GB / 30 day plan is the value pick: a full month for $9.50 more than the 7 day plan and three times the data. Per gigabyte the curve improves only slowly, from $6.00 down to $4.50 on the 10 GB bucket, so buy the larger plans for the time window rather than for a big discount.
Network
The plan is sold under the operator name Retba Mobile and the supported country is Senegal. The product page publishes the speed as 4G, and real speed still depends on the mast, the handset, and the carrier Fair Usage Policy. Senegal is covered as one country on this plan, and the network is dense in Dakar, the Petite Côte resorts around Saly, and the northern city of Saint-Louis, with thinner service as you go east towards the interior and the Casamance. Two geography points matter for a plan like this. Senegal all but surrounds The Gambia, which runs as a strip inland from the coast, so a day trip there crosses into a different country and needs its own plan. It also does not cover Mauritania, Mali, Guinea, or Guinea-Bissau, so an overland route up the coast or into the Sahel needs more than one eSIM. The product page does not publish a coverage map, so treat remote stretches outside the main towns as outside the guarantee.
How much data you actually need
Maps, chat, and bookings sit inside 1 GB for a short stay. A two-week trip with daily photo uploads is the 2 GB or 3 GB plan, and 5 GB covers a longer stay or hotspotting a laptop. Hotel Wi-Fi is standard in Dakar and Saly and patchier elsewhere, so plan the bucket around where you are staying rather than around the calendar.
Unlimited data
This product has no unlimited plan. Every option is a fixed bucket: 1 GB for 7 days, 2 GB for 15 days, or 3 GB, 5 GB and 10 GB for 30 days. If you plan to hotspot for a group or a camper, count gigabytes per day before you buy: 5 GB over 30 days is about 170 MB a day, which is fine for maps and chat and not much more.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Retba Mobile line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
The main gateway is Blaise Diagne International (DSS) at Diass, about 45 km from Dakar, with a second international field at Cap Skirring (CSK) for the Casamance in the south and land crossings from Mauritania in the north and The Gambia inland. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Senegal”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Senegal eSIM?
$6.00 for 1 GB, valid 7 days, on the Retba Mobile plan.
Q2: Which operator is on the plan?
Retba Mobile. The supported country is Senegal.
Q3: Does it include calls and SMS?
No. It is a data plan, with voice calls only through apps such as WhatsApp or FaceTime. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
No. The product page lists the speed as 4G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection and Blaise Diagne sits well outside Dakar.
Q6: Will it work outside Senegal?
No. The Gambia, Mauritania, Mali, Guinea, and Guinea-Bissau each need their own plan.
Q7: Is there an unlimited option?
No. There is no unlimited SKU on this product. The largest bucket is 10 GB over 30 days at $45.00.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a week in Senegal, the $6.00 / 1 GB Retba Mobile plan is the entry point, and the 3 GB / 30 day plan at $15.50 is the one most travellers should buy. A two-week trip with daily uploads is 5 GB at $25.00, and a month of travel or group hotspotting is 10 GB at $45.00. The published speed is 4G, coverage is Senegal only, and there is no unlimited option.
