Orange.The Service provider that suits a cellular users needs.I have been using Orange for last 8 months.
I opted for Orange mainly because of the billing method.
Many of my friends told me that I should go for Orange instead of BPL Mobile who sometimes shows the bill amount quite high than the actual use.
One of the thing one could appreciate of Orange is the accuracy in their billing.Their helpdesk service is also very prompt.
Orange has amazing voice clarity.The Talk Time plans are really suitable to everyones pocket.
I suggest everyone to go for Orange.
