Stay Connected in Nairobi
Network coverage, costs, and options
Connectivity Overview
Nairobi's actually got pretty solid connectivity these days – it's one of Africa's tech hubs, after all. You'll find 4G coverage across most of the city, and even 5G is starting to roll out in certain areas. The main carriers are Safaricom (the dominant player with the best coverage), Airtel, and Telkom Kenya. Most hotels, cafes, and restaurants offer WiFi, though quality varies quite a bit. The airport has free WiFi that works well enough for basic browsing. For travelers, the big decision is whether to go with a local SIM or an eSIM – both work fine, but they suit different travel styles. Internet speeds are generally decent for video calls and streaming, though you might hit some slowdowns during peak hours. Worth noting that data is pretty affordable here compared to many Western countries.
Get Connected Before You Land
We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in Nairobi.
Network Coverage & Speed
Safaricom dominates the market with roughly 65% market share, and for good reason – their coverage is the most reliable, especially once you venture outside Nairobi toward places like the Maasai Mara or Rift Valley. They've got 4G coverage across the city and major highways, with 5G starting to appear in the CBD and upscale neighborhoods like Westlands and Karen. Airtel is the solid second option, usually a bit cheaper than Safaricom with decent urban coverage, though it can get spotty in rural areas. Telkom Kenya is the budget option – fine for basic use in the city but not ideal if you're planning safari trips.
Speeds in Nairobi typically range from 10-40 Mbps on 4G, which handles video calls and streaming without much trouble. 5G can hit 100+ Mbps where available, though coverage is still limited. The network tends to slow down during evening hours when everyone's online. One thing to know: Kenya's mobile infrastructure is actually quite advanced – mobile money (M-Pesa) runs on these networks and it's incredibly reliable, which gives you a sense of how robust the system is.
How to Stay Connected
eSIM
eSIM is honestly the more convenient option for most travelers to Nairobi, especially if you're coming for a week or two. You can set it up before you even board your flight, which means you land with working data – no hunting for SIM shops, no dealing with registration paperwork, no language barriers. Providers like Airalo offer Kenya-specific plans that work on Safaricom's network, so you're getting the best coverage available.
Cost-wise, eSIMs run a bit more than local SIMs – you might pay $15-20 for a week's worth of data versus maybe $10-12 for a local option. That said, the convenience factor is significant. You keep your regular number for two-factor authentication, you're connected immediately, and there's no risk of losing a tiny physical SIM card. The main downside is less flexibility – you're locked into whatever data package you bought, whereas local SIMs let you top up as needed.
Local SIM Card
If you're going the local SIM route, Safaricom is your best bet. You can buy SIM cards at the airport (there's a Safaricom shop in the arrivals hall at JKIA), at their retail stores around the city, or from countless small shops – they're everywhere. You'll need your passport for registration, which is mandatory in Kenya. The process takes maybe 10-15 minutes if there's no queue.
A Safaricom SIM costs around 100 KES (less than a dollar), and data packages are pretty affordable – roughly 1,000 KES ($7-8) gets you 10GB valid for a week, or 1,500 KES ($10-12) for 20GB monthly. You can top up using M-Pesa mobile money or buy scratch cards at virtually any shop. The main hassle is just dealing with the registration process and making sure you understand the various bundle options, which can be confusing if you're not familiar with the system.
Comparison
Here's the honest breakdown: Local SIM is cheapest (maybe $10-12 for plenty of data), but requires airport queuing and paperwork. eSIM costs a bit more ($15-20) but you're connected the moment you land. International roaming is eye-wateringly expensive – we're talking $10-15 per day for limited data – so really only makes sense for super short trips where you can't be bothered with anything else. For most travelers, the eSIM sweet spot is trips under two weeks where convenience matters. Local SIM makes sense if you're staying longer or traveling on a tight budget.
Staying Safe on Public WiFi
Nairobi's got WiFi pretty much everywhere – hotels, cafes, malls, even some matatus (minibuses) – but public networks are inherently risky, especially for travelers. You're likely accessing banking apps, booking hotels, checking passport details, which makes you a more attractive target than locals just browsing social media. Hotel WiFi is particularly dicey because everyone knows travelers use it for sensitive stuff.
The main risk is someone intercepting your data on unsecured networks – passwords, credit card details, that sort of thing. A VPN encrypts everything between your device and the internet, which basically makes your data unreadable to anyone snooping. NordVPN is a solid option that works reliably in Kenya and doesn't noticeably slow down your connection. It's not about being paranoid – it's just sensible protection when you're handling important stuff on networks you don't control.
Protect Your Data with a VPN
When using hotel WiFi, airport networks, or cafe hotspots in Nairobi, your personal data and banking information can be vulnerable. A VPN encrypts your connection, keeping your passwords, credit cards, and private communications safe from hackers on the same network.
Our Recommendations
First-time visitors: Go with an eSIM from Airalo. Seriously, the peace of mind of landing with working data is worth the small extra cost. You can order your Uber, message your hotel, pull up maps immediately – no stress, no airport queuing when you're jet-lagged. It's just the smoother experience.
Budget travelers: Local SIM is technically cheaper if you're really counting every dollar – you'll save maybe $5-8 over a week. But honestly, consider whether an hour of your time dealing with registration and figuring out the system is worth that saving. For most people, eSIM's convenience wins.
Long-term stays (1+ months): Get a local Safaricom SIM. At that point, the cost difference adds up, you'll want the flexibility to top up as needed, and you've got time to figure out the best data bundles. Plus, having a local number is useful for deliveries and local contacts.
Business travelers: eSIM is really your only practical option. Your time is too valuable to spend queuing at airport SIM shops, and you need connectivity the moment you land for emails and calls. Set it up before you fly and forget about it.
Our Top Pick: Airalo
For convenience, price, and safety, we recommend Airalo. Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive. It's the smart, safe choice for staying connected in Nairobi.
