Samsung introduced a device which is in essence a lower-end Samsung Note. Called the Galaxy Grand, it runs Android on a dual-core 1.2 GHz processor, has 5-inch LCD display, and an 8-megapixel camera.
The trend to note here is the availability of the device in a dual-SIM model.
For those who follow the mobile industry, please don't fall for the "six billion mobile subscribers" stories that have been floating around earlier this year. The proper word should be "subscriptions," not subscribers. Some estimates are that there are actually fewer than three billion global subscribers, and some say as few as two billion. Granted that's still an amazing number.
The math indicates that there are possibly more than one billion people, and likely a great deal more, who have more than one mobile account, and thus at least two SIM cards. This is not niche market.
I am still waiting for Microsoft to announce support for dual-SIM hardware in Windows Phone. Unfortunately I suspect a long delay which will cost them share when and where they need it most.
