There was a time when unlimited data plans were like taboo in the internet service provisioning space in Nigeria.
But like the case of per-second billing, which appeared impossible in the early days of the telecom revolution, unlimited data plans have become regular offerings of many ISPs in Nigeria today, thanks to the intense competition in the market space.
With over 200 ISPs licensed by the Nigerian Communications Commission (NCC) and the four mobile network operators comprising MTN, Airtel, Globacom, and 9mobile, Nigerians now have more than enough choices when it comes to selecting a service provider.
While several ISPs claim to be offering unlimited data plans, not all are truly unlimited as some ISPs attach Fair Usage Policy (FUP) to their plans.
The FUP means that there is a certain threshold of your usage within the unlimited period where the speed you get becomes lower but you will continue to have access to the internet.
For instance, if your one-month unlimited subscription has a 40GB FUP, it means that you will enjoy the best speed until you use up 40GB, after which the speed you get is throttled.
In this report, Nairametrics looks at the ISPs including mobile operators currently offering unlimited data plans without FUP. These providers are ranked based on the current price of their cheapest monthly unlimited plan.
Here are the top 10 ISPs in Nigeria with the cheapest unlimited data plans as of December 2024:
