In my experience with Aircel Cellular, it has good signal coverage in remote village areas. Mobile to mobile calling costs are very cheap compared to other services. During night times SMS and call costs are very low. Good customer care support and they answering customer queries within few minutes wait. Offers at certain dates will reduce the pre-paid bills. These will be notified by offer messages. I think Internet tariff plans are not attractive. They charging the user by data transfer. Annoying service messages for paid content occupies the inbox often. Call costs to landline phones are high compared to mobile bills. I used this service nearly five years and satisfied with its call/messaging services. The internet plans are need to be attractive to keep the customer not to go other service providers. This service is good for only call and messaging services.
