Good But costly. Review on Airtel Mobile Operator

I am using Airtel from last 2 years.It was good enoghh before.There are lots of offers which are provided by the company and all that were fits in my budget.But nowdays the issue is facing by me that their network is getting worse day by day.the network signal strength is shown very low and the signal bar shows that there is no network.I live in a village.here Airtel only gives 3g network with good speed but when it comes on the 4g network I dont get any signal.I cant access 4g even if I have 4g pack in my phone.And also their net packs are more costly than other networks.they dont give me any offer now.in my new sim I dont get any data pack offer less than 250 and that is the real price for 1gb data for 28 days.so this can not be called offer it is just the pack they provided.I liked Airtel before but now I think it is not gonna work for ne.i have to choose something else.
