Er, I think its a Nokia

Research  conducted by Ipsos MORI on behalf of LogicaCMG shows that mobile operators could be losing revenue because more than half  of mobile phone users (58%) do not know the make and the model of their handset. The poll suggests that the lack of knowledge could be posing a problem for operators and manufacturers who are trying to drive uptake of advanced data services, such as multimedia messaging, video calling and mobile internet browsing.
The research found that 49% of all users know only the make of their handset, with only 42% knowing the make and model, and 9% knowing neither make nor model. Men and younger users (in the 15 to 34 age group) are most likely to know details of their handset. These groups are also those most likely to engage with advanced data services, such as MMS and mobile internet browsing, than  women and the 55-plus age group.
Logica believes that accurate, real-time handset details will enable operators to market relevant extra services with which the users handset is compatible, and that having access to this information will be invaluable to enable operators to cross-sell relevant services, especially when a query is made to the customer call centre. With only 42% of those surveyed knowing both the make and model of their handset, it says, the number of additional revenue-generating activities that can be encouraged and communicated by a customer care representative is limited. The exact handset details are also required for the correct service book, or software updates, for a new data service to be automatically delivered to a phone, enabling the subscriber to begin using it.While consumers themselves may not be overly interested in knowing the details of their phone, it is important, says Logica, for customer service specialists to know enough about the handset to be able to offer the appropriate technical advice.
This research demonstrates that many operators could well be trying to sell advanced data services, based on the incorrect assumption that the users they are communicating with have basic knowledge of their own handsets says LogicaCMG telecoms Chief Operating Officer, Paul Gleeson. Often, this is not the case; the language used by the customer service advisor can be inappropriately technical and, as a result, they could actually be putting a number of people off using their handsets.
Mobile data services are much more complex to deliver to consumers than voice services just sending through the right service book to enable MMS depends on knowing to which handset it is going. Operators and manufacturers can help in the roll out of new mobile data services by ensuring that they control this kind of basic information, rather than depending on their customers often limited knowledge.
The survey was conducted by Ipsos MORI on behalf of LogicaCMG in the second half of October 2005. The research study is based on a nationally representative sample of 761 mobile phone users age 15 and over, representing approximately 39.5 million British adults. Ipsos MORIs continuous tracking vehicle, the Technology Tracker, helped place the research findings in context. Ipsos MORI surveys circa 4,000 adults aged 15+ in Great Britain on their use of technology on a monthly basis.
