It is the wrost mobile network because they advertising about airtel 4g in all channels as high speed net work in any remote area if it is at the top of a hill there is 4g is available.
After watch that advertisement I took a airtel 4g sim and went to my house after 10 day the sim didnt activated the coverage signal is zero I called the shop keeper he said me that there is no problem at the sim .
One day I keep phone along with me when going to town and I surprised the sim get activated only has a single point of coverage.
so I realised that they are lying as where ever you go there would be have the 4g net but it is really lie.
They are try to fool the costomers.
Dont use it
