Since Jio has launched greater services at a minimal cost initially, it has become a tough time to other service providers. They have come up with new data plans and offers, some decided to unite with each other. In this process airtel launched 4g speed data similar to Jio with free voice calls with different plans, but thing is airtel does not support volte mode which results in the fall of data running in 4g to 2g speed. If user wishes to run it in 4g he need to set up the Sim in LTE mode by following a certain procedure which disables incoming calls. So finally airtel does not provide a good service. In the end there is no worth for money. Moreover airtel always promotes post paid users which is again a huge loss for consumers. since, until the user uses the Sim for 3 months he cannot change the number and he cannot shift the operator he have to use post paid which has less benefits at a high cost. Therefore I am completely unhappy with airtel. In spite of spending lot of money on a plan(which does not worth that much) I did not get the minimum 4G service.
