I have been using orange for five years from november 1997 when it was max touch and I have been absolutely satisfied with their service, at present they have the best service in mumbai and they provide the best feedback to all of your queries within the speculated time. I have had no hassles at all with them in the last five years and the schemes specially newly introduced for us the extended night speak in which we also get the sundays free is just too good and their billing system seems very clear to me. the only problem which I have faced with orange is in the night time I experience dropped calls occasionally and their messaging reaches delayed sometimes especially if sent to another service provider. Otherwise if you are thinking fo buying a mobile choose orange and if u r an orange customer hang on to it man, they are the best in business in mumbai.
