I just got my redmi yesterday
Using my work sim and personal sim now.
Pros:
I dont need to carry 2 devices
Bluetooth can just use 1 and connect to both lines
Can double up when travelling
Cons:
Phone no 4G
Screen not as precise as iphone 5
Camera sucks
Iphone seem more powerful
U didn't try before buy meh. Please lah, don't compare with 1k phone. But I can say 1k phone may not have more feature as compared to a budget phone meh.
