A Gambian SIM costs nothing to obtain and very little to fill: Africell gives the card away at its outlets, and Comium sells 5 GB for 250 dalasi, about 3.35 dollars. The two travel eSIMs sold for the country both run on that same Comium network and charge 27 to 44 dollars for 5 GB. The gap is wider here than almost anywhere else on this site, and it exists partly because Gambian operators compete hard for a small market of four networks and fewer than three million people. What the local card asks of you is a passport at the counter and a visit to an outlet, which on the coast is rarely more than a short walk from your hotel.

Four Networks Competing for a Small Country
Most countries this size support two mobile networks. The Gambia has four, which is the main reason its data prices are so low and its promotions so frequent. Africell is the giant, holding roughly 63 percent of subscribers according to regulator statistics reported in 2024, and it has been here since 2001. QCell, part of the Gambian QGroup, sits second at around 28 percent and pitches itself on speed, with 5G in the Greater Banjul Area and a home fibre business. Comium and the state-run Gamcel share what is left, each near 5 percent.
Mobile money comes with the line
Each operator runs its own wallet: Afrimoney on Africell, QMoney on QCell, ComCach on Comium. For a visitor the useful part is buying airtime and bundles from the wallet rather than hunting for scratch cards, and paying some small traders who prefer a transfer to change. You do not need a wallet to use data, but the outlet will usually offer to set one up when it registers your SIM.
Which network is best depends on where you sleep. On the coast between Bakau and Kartong all four have 4G, and the hotel you pick matters more than the operator. Upriver, Africell's head start in tower count shows, and it is the safest single choice for a trip that includes Janjanbureh or the Gambia River National Park. Comium is the cheapest per gigabyte, and it is also the network both travel eSIMs use, which makes it a useful point of comparison: you can buy the very same signal for a fraction of the price.
What a Gigabyte Costs in Dalasi
The figures below come from the operators' own published tariffs, read on 12 October 2026, and are converted at about 74.5 dalasi to the US dollar. Africell's regular bundles are activated by dialling *120#; Comium's through *606# or the short codes listed on its site.
| Operator and bundle | Data | Validity | Price |
|---|---|---|---|
| Comium 14-day | 5 GB | 14 days | D250 (about $3.35) |
| Comium 21-day | 10 GB | 21 days | D500 (about $6.70) |
| Comium 30-day | 12 GB | 30 days | D600 (about $8.05) |
| Africell regular | 3 GB | 45 days | D255 (about $3.40) |
| Africell regular | 5 GB | 60 days | D595 (about $8) |
| Africell regular | 10 GB | 60 days | D950 (about $12.75) |
| Gamcel weekly plan | Unlimited | 7 days | D750 (about $10) |
| Nomad eSIM (Comium) | 5 GB | 30 days | $27 |
| Airalo eSIM (Comium) | 5 GB | 30 days | $44 |
Two patterns stand out. Comium is the price leader on small and medium bundles, undercutting Africell by more than half at 5 GB, though Africell's validity is far longer, so a 5 GB Africell bundle bought in January can still be in use in March. And the long validities make the local card useful for returning visitors: many Europeans come back to the same Kololi hotel every winter.
The big-allowance options
Africell's 4G Mega bundles trade speed for volume, for example 90 GB over thirty days for D1,500 at a cap of 0.75 Mbps, split between day and night hours. That speed is fine for messaging and maps, poor for video calls. Gamcel's subscription plans are uncapped by volume, from D750 for a week to D1,800 for a month at 200 GB. QCell publishes its bundles mostly as promotional images, so we could not read a reliable price list from its site; ask in a care centre.
Registration: A Passport and a Few Minutes
SIM registration has been compulsory in The Gambia since 2012, when the regulator PURA set a deadline and threatened to block unregistered lines. Enforcement has teeth: in 2019 PURA fined Africell, QCell and Gamcel after finding agents selling cards that were already active without the buyer's details on file. The result is that a reputable outlet will not sell you a working line without identification.
Bring the passport itself
A photo on your phone will not do. Africell's own guidance asks for valid government-issued ID, and for a foreign visitor that means the passport.
Let the agent register the line
Travellers consistently report that Africell activates the card within minutes. We found no evidence of the fingerprint or face capture that several neighbouring countries now require, but rules change, so allow a little time.
Buy the bundle at the counter
Ask the agent to load a data bundle before you leave, and check the balance with the operator's USSD menu while you are still in the shop.
Compared with the biometric queues of some other West African countries, this is light paperwork. The real cost is the trip to an outlet and the fact that the line is tied to your passport. For most visitors that is a fair trade for data at a tenth of the eSIM price.
Where to Pick Up a Card on the Coast
Africell's website states that a SIM card is free at its outlets, and the network of branded shops and authorised agents is dense across the Kombos. The busiest cluster is around Serrekunda market and Westfield junction, but there are outlets along Kairaba Avenue, at Brusubi and close to the Senegambia strip, so a guest in a Kololi or Kotu hotel rarely needs a taxi. QCell's care centres are concentrated in the Greater Banjul Area, with its headquarters on Kairaba Avenue.
Topping up away from the shops
Once the line is registered, credit is easy to find. Scratch cards and electronic airtime are sold from roadside kiosks, petrol stations and small shops all the way up the river, and Gamcel's electronic top-up even has a local nickname, Nopal, which roughly means convenience. Bundles bought with that credit are then activated by USSD code from your own phone.
What we could not confirm is whether a working SIM counter operates inside Banjul International Airport in 2026. A 2018 traveller account describes an Africell booth there, but no current source places one in the arrivals hall, and package transfer coaches leave quickly. Plan on buying your card the day after you land, on the coast.
Bring dalasi in small notes. Outlets are cash businesses, and paying for a bundle with a large note can mean waiting while change is found.
The Gambia's Own eSIMs
A local eSIM is now a real option here, which is not true of many countries in the region. Africell sells its eSIM for a one-time 150 dalasi activation fee, about 2 dollars, and in October 2026 was adding 3 GB of free data on activation, terms permitting. QCell offers an eSIM through its care centres in the Greater Banjul Area for a one-time activation fee that its site does not quote.
Why a local eSIM appeals
The limits
For a returning winter visitor with a dual-SIM phone, the Africell eSIM is arguably the best setup of all: register once, keep the profile, and top it up each season from a scratch card.
Senegal, the River and Which Card to Carry
The country's shape decides a lot. The Gambia follows the river inland for more than 300 kilometres, never much wider than a long drive across, and Senegal wraps around it. Travellers bound for Dakar, the Sine-Saloum delta or the Casamance cross a border at Amdalai near Barra, at Farafenni over the Senegambia Bridge, or at Seleti in the south. Gambian SIMs used to be a costly roaming proposition once over the line. Under the memorandum PURA and Senegal's ARTP signed to apply the ECOWAS roaming regulation, capped roaming between the two countries was due to start on 1 March 2026, with incoming calls free for up to thirty days. PURA says The Gambia already had similar arrangements with Côte d'Ivoire, Ghana, Sierra Leone and Liberia.
| Your trip | Best option |
|---|---|
| Under five days, resort hotel | Nomad 1 GB week ($9) or hotel WiFi |
| One to three weeks on the coast | Comium or Africell bundle bought on day two |
| Upriver to Janjanbureh or Basse | Africell, for its larger tower network |
| Arriving late at night | Nomad eSIM installed at home, local card later |
| Returning every winter | Africell eSIM or SIM kept active between visits |
The eSIM makes sense for the first night, for short trips and for anyone who wants nothing registered in their name. Past that point the numbers do not support it. The full eSIM comparison, with every plan on both providers, is in the Gambia eSIM guide.
Frequently Asked Questions
Is the Africell SIM card really free?
Africell's website says you can get a SIM card for free at its outlets. You still need your passport for registration and you pay for whatever bundle you load. A 3 GB regular bundle valid for 45 days costs D255, about 3.40 dollars.
Which Gambian network has the cheapest data?
On published tariffs, Comium. Its 14-day 5 GB bundle costs D250 and its 30-day 12 GB bundle D600. Africell charges D595 for 5 GB but gives sixty days to use it. Gamcel's weekly unlimited plan at D750 is the cheapest way to avoid counting gigabytes at all.
Do I need my passport to buy a SIM in Banjul or Kololi?
Yes. Registration has been mandatory since 2012 and the regulator has fined operators for selling unregistered lines, so a proper outlet will ask for it. Bring the original rather than a copy or a photo.
Can I set up a Gambian eSIM before I travel?
Not a local one. Africell's 150 dalasi eSIM and QCell's eSIM are both issued in person at an outlet with ID. If you want to land already connected, a travel eSIM from Nomad is the way to do it, at travel eSIM prices.
Will my Gambian SIM work if I cross into Senegal?
It will roam. Regulators in both countries agreed to cap roaming charges and make incoming calls free for thirty days from 1 March 2026. Check the current data roaming rate with your operator by USSD or at the outlet before you cross at Amdalai, Farafenni or Seleti.
