wil iphone 5s A1533. T-mobile unlocked version from US. work in india?

just hope you do not need warranrt or post warranty support

The problem, Peter, is only that there is no local Apple warranty support in India but one can still call the US toll-free number and get the needed support. The US warranty still remains intact.

Please look at the previous responses to this question.

Oh no it does NOT there is NO international warranty on iPhones

You have to carry iphone back to US and if any Indian backstreet shop has touched it warranty is void period
