Is Lagos just that much wealthier than the rest of the country? Is there a wealthy professional subset that can afford this? Or is it mostly business users who need lots of bandwidth?
Could the OP or Mods please change this to a less catchy and more accurate title like `Uncapped ISP for Lagos` .
9500NGN = £25/month, which would get you 40/10 VDSL2 uncapped in the UK.
Costs are high and anything less than perfect, low latency connectivity supporting 20+ HD Skype calls is unacceptable results in NGOs bitching about the service they get for free.
How are the nodes connected? Is it a mesh?
How about the backhaul? How's that handled and is it still under the control of the telcos?
Do customers need to install wifi receivers on their roof tops ?
Can you go inside flats ?
Do you need line of sight to the towers from homes ?
How far can a house be from the tower ?
What about roads and water? "According to a report for the World Bank, average road density on the continent is 204 kilometres of road per 1000 square kilometres of land area – only a quarter of which is paved. In contrast, the world average is 944 kilometres per 1000 square kilometres with more than half paved." 
Not that I expect a YC company to solve African roads...
Even the best regional roads in Africa are two lane roads. Unlike the US, cars have highly variable top speeds though, which means nearly constant passing. Cars will drive in the wrong lane for significant periods of time and hastily merge back. But there are large number of buses that are heavily incentive to go quickly at any cost, so they will often off road and suddenly pass on the left. I've seen a two lane road with 5 lanes of traffic on it.
That's the best case scenario. A large chunk of the country is only accessible via rough road spurs. If you're trying to deliver, say hypothetically, 10 tons of fertilizer and seed on the back of a truck, it means you're going 10mph instead of 45mph.
My family worries about me getting murdered in Kenya or the government suddenly melting down, but really traffic is what they should be worried about. And this is Kenya, which is one of the most developed countries in E. Africa. There's a real need for some more roads.
Edit: The currency, the naira, lost quite a bit of its value last June  when the central bank allowed for it to become (more) market-driven .
Right now at N400 per dollar (it was 450 barely a month ago), $280 is 112,000 naira. Top earning high school teachers get N50k monthly. Entry level bankers get N70k. I know an accountant for a media house (Masters in finance) who earns N80 and works 10 hours per day for six days a week.
Although, if I'm honest I fail to see the "YC-grade" innovation in this project versus the myriad of WISPs that have been so popular for more than a decade. Does it all boils down to the unmetered business model?
So the user can consume any amount of data from the global internet?
How do you manage that?
The next question is, "What areas of Lagos have coverage?"
Their site doesn't say. Only gives pictures of buildings of their customers.
Yes, your data is unlimited but but your speed of 128k limit how much you can actually use.
In this case, after a short chat with their online reps they offer 2-5 mbits. At 5 mbits this translates to roughly 1.6 Terabytes of data over 30 day period.
Don't get me wrong, what they are doing seems great! I just wish they would show their speeds upfront and the download/upload ratio.
At the same price the biggest telco is only willing to give about 12gb capped data. And it's no where near the quality of a zuku connection.
I think it might have to do with the physical infrastructure. A cell tower can be seen as an access point shared by millions and therefore has to have limits on what each device can send and receive. Home internet is via fibre and an an access point shared by only memebers your household.
