Perhaps you have been faced with this problem before of depleted Airtel airtime while having money in your M-Pesa. So how do you go about this, especially if you can’t physically go to a shop to make a purchase? Simple, M-Pesa offers a way out of this.

• Go to your M-Pesa menu
• Select Lipa na M-Pesa option
• Go to the pay bill and enter 220220 as your pay bill number
• Enter the amount of airtime you’d want to purchase
• Okay, the transaction and subsequently confirm the transaction
• You will receive an M-Pesa message confirming the transaction

Depending on the processing speed, you will receive a Chap Chap message from Airtel confirming an airtime purchase.
However, at times this message delays. In the event you haven’t received a Chap Chap message from Airtel, dial *133# to confirm your balance.

The chap Chap charges are generally dependent on the amount of airtime you purchase for instance airtime purchases below Ksh. 99 are usually charged Ksh 2. Transactions above this figure attract higher fees of up to Ksh 23.
There you have it folks that’s how you get to make cross-network airtime purchase using M-Pesa to Airtel.
