The world best network is airtel and I am using this mobile operator for 8years .And I have no problem about taken it because-
1.this company network coverage is best coverage in india and other , one time I was going to a forest when I see my airtel sim network it is fine but I have a other sim but their was no signal of the sim
2.And the most atracked think of this service provider is its customer service and helpline .its helpline number is for 24hr means it is really good
3.another think of this cost of inernets and calling is so low comparing other because its special offer us so atracking and also surprizing
For this resson I like most to this MO
