Discounted Airtime for All Networks

Bigisub offers discounted airtime across every major Nigerian network, including MTN, Glo, Airtel and 9mobile. Rather than paying full price at a retail outlet or through your bank, you can buy airtime at wholesale VTU rates and save on every recharge. Whether you are topping up your own line or sending credit to someone else, you always pay less than the standard price.

Our pricing is transparent, with no hidden charges. The discount you see at checkout is exactly what you get. Rates are updated in real time so you always know what you are paying before you confirm the transaction.

Instant VTU Delivery

When you buy airtime on Bigisub, the credit reaches the recipient in seconds. Our VTU infrastructure is fully automated and runs around the clock. There are no manual steps, no queues, and no waiting. You confirm payment and the airtime arrives almost immediately, whether it is 2 AM on a Sunday or noon on a weekday.

This speed matters most when you are reselling. Your customers expect instant delivery, and Bigisub ensures you never leave them waiting. Every successful transaction builds trust, and trust is what turns first-time buyers into repeat customers.

Resell Airtime for Profit

Airtime reselling is one of the simplest ways to earn in Nigeria. The concept is straightforward: you buy airtime at a discount on Bigisub and sell it at face value to people around you. The difference is pure profit. You can serve friends, family, neighbours, WhatsApp groups, or an entire local community, all from your phone.

There is no minimum order, no monthly target and no subscription fee. You start whenever you are ready, scale at your own pace, and withdraw your earnings to your bank account at any time. Many of our agents started with just a few hundred naira and now process thousands of transactions every month.
