My family member and also I am using this company sim card.( prepaid) .
Some time its shown no network in phone.
Network coverage of this operator is not much good.
Some time voice cut during the talking through this operator.
Customer service of airtel is good, If you problem regarding this airtel sim issue.they told what to do now., and salve the issue.
Charges of calls are very high, internet speed is slow compare then other network.
Charges and billing I am not happy with this operator.
