I am a very heavy data user and consume data in the region of 70GB - 100GB of data per month. In the past, I used to subscribe to the MTN Pulse binge data bundle of 2GB for 2 days. 3 months ago after I got a new smartphone and inserted my airtel sim card, Airtel sent me a message telling me that I am eligible for a 100% data bonus for three months if I purchase data plans within the price range of 500 to 4000 naira. Since then, I have always been doing the 3000 naira for 20GB (10GB main data and 10GB bonus) and I usually do this like 5 times a month.
Now, the offer has elapsed and I am at crossroads as to the best data plan available on either MTN or Airtel because they are the best in my location. Spectranet and Smile are out of it as I am either in Lagos, Abeokuta, or Ibadan, and not one of those service providers has coverage not to talk of excellent coverage in those three areas.

On checking the router plans between Airtel and MTN, I am at a crossroads on the best to go for between the two because they offer competitive prices but MTN slightly has the advantage because it includes a 100% bonus for 3 months on purchase of their Hynet Flex Router.

Who has used any of the two and what can you say about it?
Any advice for me?

Thank you.
