Best ever India calling service

I am using this service since three months, have spent over 100 dollars with dial91 in this three months and found that this is the best service. I am using apple app to make calls which is not using my cellphone minutes. I love this concept. Only one call in this three month echoed back but I will not take off any point for that. Never had to use their customer care service to can't comment on them. Over all, I have no complains. 1cent a minutes with such an amazing call quality is aged to find. I am always recommending this service to friends and family.

Amazing Service

Actually I was using a different service to call ny family and parents in India and I came to know from one of my friend abt dial 91. After I used it once then there is no gng back, dial 91 is just superb. Voice is really crystal clear. I just loving it.. There are others as well who provide 1 cent per min but they dnt provide this quality of voice. It is simply the best ...

Awsome Awsome Awsome

I have been using this service from past 3 months. Its been a wonderful experience so far. Its the best service available to make calls abroad. The awsome feature is that there is no time frame for you to use the minutes. I have been recommending this to everyone.
