This is my first review @ MS. I bought the Micromax Q3 this January solely for its dual sim feature and affordability. I already use a Nokia Supernova, but juggling with 2 sim cards I realized going for a dual-sim phone was an easy option. I did not expect any additional features, though the 8 mb memory was a big letdown. The camera is 1.3 Mp, but the output is like that of a VGA cam. The major factor however is that I can now use both my personal and official sim cards simultaneously. That is the only reason I am carrying this bulky performer in my pocket. Its ironic that so many people mistake the Q3 for a Blackberry on first look. I am not complaining about that at all.
Verdict: Go for it only if u want a affordable dual sim option.
Keep enjoying life!
