The best thing about that idea( mobile operator) is about network coverage and customer service
its network coverage( signal strength) is very good even it is village and city and outer area .
and his customer service is available 24*7 and even its postpaid and prepaid .
I have both sim postpaid and prepaid both services are good .
its charges and billing are quite low and good
its internet is speed is very fast as per my personal experience and also its VAS services is very good
I love it
