T-mobile international roaming not working in India


    I am currently traveling to India and am in the city of Pune. International roaming doesn't seem to work for the most part for voice calls or text messages. Even data speeds are very slow. The phone shows its roaming on Idea Cellular's network.


    When I was in Mumbai for a couple of days, it was roaming on Vodafone's cellular network and that was much better.


    Any help would be appreciated.
