InMobi SmartPay and Opera Software today announced their partnership to bring InMobi’s SmartPay mobile payment platform to Opera’s mobile browser users worldwide. InMobi SmartPay will enable Opera users to pay for digital goods in key markets around the globe, when they make purchases with publishers that partner with InMobi.

InMobi is also the largest independent mobile advertising network. The recent acquisition of Sprout, an HTML5 authoring platform for mobile rich media, helps expand the InMobi offering to creative agencies and brands.
