Mobile payments company Bango has acquired the US-based carrier billing firm BilltoMobile in a deal worth $3.5m (£2.4m) as it aims to expand is presence in the North American market, both in app stores and with online retailers.

BilltoMobile is currently the only operator service integrated into all four major US mobile operators, covering over 300m connections and processing billing payments for app stores and merchants including Google Play and Microsoft.
