One has to bear in mind that right at the moment, the OnePlus One smartphone from OnePlus does not come with dual SIM slots, and neither does it have the option for users to pop in a microSD memory card should they wish to expand upon the availability of the internal memory.
Of course, there has been speculation and whispers going around that this might very well be the next iteration of a smartphone from the company, although some might make a venture to claim that this is the recently leaked OnePlus One mini. At the end of the day, any good rumor out there would need to go through the passage of time before it is confirmed whether all that has been shared is true – or otherwise.
