I m the regular coustmer of idea from past 5 years .it provide all typea of sim like 3g , 4g . When we talk about networks , in big or metro cities its networks are good but when we move towards small cities or towns there is huge down fall in network sections . Idea gives very good and attractive offers like I m using the plan of 1498 as a one time aishwaryasingh23ment then it will give me 1 gb data @51 every time when I recharge . So this is very good offers from idea. When we call in coustmer care they are coperative . I had used their postpaid plans , they never add extra charges that is the good quality of them . There bills are accurate .
