Is it beneficial to buy unlocked iphone 5s from singapore to use in india?

Hey i'm confused whether to buy iphone from singapore or not. To use it in india… Is it beneficial to buy from there?
and wat sort of problems shud i probably face on using it in india

It would be a good idea if it is cheaper in Singapore than in India.

Ok i'm not pretty sure of this. But the major problem you can face most likely is battery issue. Phones are designed according to country's cellular network depending on bandwidth of signals.Ao if you use an iPhone of other country in India the responce of antena could not match with India's so if struggles to get that network. And your phone will work fine with any network but battery will drain quickly
