Everybody knows 4 four sim card phone is not a new thing but all previous 4 sim phones are non-smartphones. With android driving smartphones cheaper and cheaper, some particular people wants triple sim android smartphones and quad sim android smartphones
The other day, somebody was talking to me and ask me to give out the news that they would have a 4 sim android smartphone available in around March in 2014. The guy said they are doing R&D on the phone and the phone will be based on MTK solution (but actually I do not think anyone else will make this kind of solution except MTK). I do not know if it is true but lets just wait.
