The reason I am asking is that I live in Karachi where cell phone snatching is a common phenomenon. Hence, I want to carry a cheap handset when I am in areas prone to snatching and will use relatively better set when I am at decent places.
I understand there is no decent place where you would not get robbed but chances of not getting mugged in decenent areas are slightly higher.
Is it possible to get a duplicate sim for the same number and both work.
Obvious question would be, which one should ring? but there must be some way around in this tech world.
