Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Unfortunately No. India have the frequency of 1800 and 950 where the US have frequency of 1900 and 850.
Samsung SGH-A107 has the frequency of 1900 and 850 and it will not work on countries with other frequencies. It is mainly designed for US and it is not a world or global phones.
This is an hardware limitation and nothing to do with locked or unlocked. It doesn't matter whether it is locked or unlock, it will simply not get the signal. There is no way to change the frequency because it depends up on the hardware.
I know this is not the answer you want, but this is the reality. If you are not satisfied with the answer, please don't rate me bad or poor as it will badly affect my job here. You don't have to rate anything. You can close this page without rating and ignore the rating request emails if you receive any.
