One of the biggest concerns Kenyans have when buying airtime online is hidden charges. With TeelPay, you can buy airtime for all networks from M-Pesa without paying any markup on top of the standard M-Pesa transaction cost.

How the pricing works: You pay exactly the airtime amount you request, plus only the standard Safaricom Lipa na M-Pesa Paybill transaction fee, the same fee you would pay for any other Paybill payment.

Step 1: Go to your M-Pesa menu and select Lipa na M-Pesa, then choose Pay Bill.

Step 2: Enter the business number 4142145, which is TeelPay's official paybill for buying airtime for all networks including your chosen network.

Step 3: For the account number, enter the full your chosen network phone number you want to top up (including the country code or leading zero as prompted).

Step 4: Enter the amount of airtime you want to buy, then enter your M-Pesa PIN and confirm.

Step 5: Within seconds you will receive an M-Pesa confirmation SMS, followed shortly by a top-up confirmation from your chosen network itself.

Because the transaction runs through Safaricom's official Lipa na M-Pesa Paybill system, your money is protected by the same security you rely on for every other M-Pesa payment. You get an instant confirmation SMS from M-Pesa, and a second confirmation once the airtime lands, so there is always a paper trail if you ever need to follow up on a transaction.

Because there is no extra commission added by TeelPay, buying airtime this way is often cheaper in practice than paying an agent who may round up the price or charge a small handling fee.

This matters because Kenya's mobile economy runs on connectivity. From M-Pesa itself to WhatsApp Business, ride-hailing apps and mobile banking, almost every essential service assumes you have airtime on your line. Running out at the wrong moment, during a job interview call, a delivery pickup, or an emergency, can be more than an inconvenience. Having a reliable, always-available way to restock airtime, one that does not depend on an agent's stock levels or opening hours, is part of why Paybill 4142145 has become a habit for so many Kenyan phone users rather than just an occasional fallback option.
