📝 The Lagos data reality
Twenty gigabytes a month is the heavy-user tier — enough for daily video calls, plenty of streaming, big downloads and a phone that doubles as a hotspot. At this size the smart question is not which network has 20GB (they all do) but which one delivers it at the lowest price-per-GB while still giving you coverage you can rely on, because a cheap 20GB you cannot actually use at speed is no bargain.
On raw price, Glo's large monthly bundles usually win the per-GB race at this level, which is why value-focused heavy users gravitate to it. But the practical answer depends on where and how you use the data: if your area or your work needs rock-solid connectivity, MTN or Airtel's 20GB is worth the small premium for the reliability, while Glo is the pick if you are chasing the cheapest bulk data and can tolerate its coverage dips. Many Lagos power-users split the difference — a big Glo data bundle for downloads and streaming, an MTN or Airtel line for anything that must not drop.
After the 2024 tariff increase, every network's 20GB got more expensive, so it pays to compare current rates rather than rely on old prices, and to check whether a slightly larger multi-month bundle brings the per-GB cost down further. Buy via USSD or the network app, watch the 30-day validity, and if you regularly burn through 20GB, price a home ISP against it — at heavy usage, fixed internet often works out cheaper and faster than topping up mobile data.
