I am useing airtell connection number no [protected] from tha last three months and recharging with rs 349. I straing to note that only data is on 4g net but voice calling on 3g net. We can not make call from 4g net but campany charging on recharge of 4g. So data is on 4g but voice call is on 3g.
Even 4g is also not working properly. So many time call is rejacted from other providers.
