Well here is the best service provider to our indians it is not only best in network coverages but also for its offers I can found airtel network in any small villages also.
Well I m using airtel sim for last 5 year I dint fell any trouble with the operator its the. its service so nice even through once I unknowningly locked my sim then immediately contacted to sim customer care they solved it with in few minutes thanks to them though sometimes they lots time to pick my call which irritated so much times.
There customer services so nice. well comes to packages of talktime internet and net calls but sometimes they increases the charges I dont know why and also they changes the tool free numbers so sometimes at that I need to call the customer care and some times friends complaints that airtel has unnessary cut there balance but I dint experienced it but I loved the service of night unlimited for 8 rupees and 1gb 3g for 49 rupees I helped me so much though it taken away my sleep but I like it.
Well comes to the 4g network its so fast and I just love it. I completes my downloads in few minutes and videos streams with any sot of buffering, the browing is to fast that no network is as fast as no other can compete it in india I also tested with other network no one can touch it but there is problems it finishes my wallet also so fast its so cost but the 4g service is not available throught the india still there so many villages where 4g is not available I few months I thinks all over india will get 4g services but there is saying that 4g mostly depends on the area youre in well I dont about it. well comes to speed test it is different in different areas it is not stable.and the best offers airtel providing in india is 4g at he price of 3g. the products that airtel provides are airtel 4g and 3g dongels which are very good in design but also in speed depending upon the plans we take. The other product it provides is 4g wifi router which comes in white for the price 2300 with can be charged and battery is removable and battery comes upto 5-6 hours. here comes we can insert our 4g sim and click on the button we get hotspot, not only 4g sim but also 3g, 2g also it gives different lights indicating which network it is, it also work so nice.so I would like to say if any one using two sims then make airtel as your primary sim but helps lot though sometimes it irritates while contacting to customer care but it is really good in every aspect in network coverages, though few plans to cost but airtel really helps.
