Micromax had launched Unite 2 also called the Micromax A106 with 4GB internal storage, but recently some users had commented that they got the handset with 8GB storage. The A106 indeed is now available in both 4GB and 8GB versions and the price difference between them is approx Rs. 250.
You can check the full review of unite 2 A106, the review is with 4GB storage, I did it in the month of May. The A106 is now listed on Flipkart with both 4GB and 8GB options. Looking at the price tag it makes sense going in for the 8GB version. Some offline stores are only selling the 8GB and some the 4GB version so make sure you are aware of it.
As far as the Unite 2 specifications are concerned they are the same only difference is the internal storage space. Micromax Unite 2 is powered by MediaTek MT6582M quad core processor running KitKat on a 4.7 inch screen.
It comes with 5MP primary camera with LED and 2MP front camera. This dual SIM handset supports 3G, Wi-Fi, Bluetooth and GPS. There is 1GB RAM and now optional 4GB/8GB internal storage. The A106 houses a 2000 mAh battery.
