They have confirmed that I need to have an active bundle, but the bundle won't be consumed during the process of transacting.
However, I find it funny. Why should I have an active bundle. Si waache tu we use it because I use mpesa the most. This month I think nimenunua 15MB pekee on their network.
Equity Bank app can work with any network. The same is also true with other bank apps. Hata kama ni sniffing, hii yao ni so "Apple-lish"
