While some states are still using 3G some states in Nigeria already have full access to the 4G LTE which was revealed by network providers.
We can say major cities in many states have access to this 4G LTE Network but sadly haven’t gotten to some areas (mostly rural) in many states.
Airtel, 9Mobile, MTN, Spectranet, Glo Ntel all offer 4G LTE. For those that have a device that supports the 4G Network; the upload and download speed is lit. Especially when using Ntel.
Before buying a 4G SIM, MiFi or Dongle you should know whether the 4G Networks covers your location.

As for Airtel and 9Mobile, it is expected that it reaches a good number of states in the next 6 months. At the moment you only have access in Abuja and Lagos.
