The challenge:
Execute a complex mobile study with high user engagement.


The leading telco provider wanted deeper insights into their customers’ online mobile behaviour and to understand their web-usage activities when using Wi-Fi, as opposed to their phone’s data allowance.

Pureprofile designed an intricate study across three stages –
