Are you looking for where to buy cheap data on MTN, Airtel, glo and 9mobile? I have an idea where you can purchase that.

If you need cheap data for as low as ₦260 for 1Gb that would last for 30 days before it expires then try gablinks

This site is durable and efficient. Am speaking from experience because i have tried it before and it worked for me. Am still currently using it.
Though, they're many websites you can buy Data for cheap price but am mentioning gablinks because it's one of the best.
