We had a couple of interviews with various top executives of Nokia SEA yesterday and one of the number of questions I asked revolved around their introduction of dual/double SIM phones.
Executives believe they are not really late in getting into the dual SIM market considering that a lot of regions do not favor this kind of market. It’s primarily because of telco subsidies and handset exclusivity (and thus, the seemingly limited demand for these types of phones).
Likewise, Nokia believes that people who tend to use dual SIM phones are those who manages their consumptions a bit tightly and thus would lean towards getting the more affordable models (their reason why the Nokia C1 and C2 are basic phones). They added though that as the market matures, they will be introducing dual SIM handsets in the mid-range level (probably before the end of 2010).
There are also other factors to consider, including battery life (read more on Resistance to Dual SIM Phones) among others.
