Aircel maybe cheap in plans with rate but is not worth it first of all it it not available all over india so I cant see a reason of not buying also the signal strength is really poor I mean they dont give sufficent signals for even calling thats really poor also if u often gets call hung up in between dont get surprised you will be furious but what can be done the only thing that can be done is not buy it there are others good network service providers like airtel to buy from.
