Upgrading SIM from 3G to 4G? Your consent is a must now
As per the new addition, the SIM can be activated only with a clear go-ahead from mobile users and on their request. Under the process, after receiving the request for SIM card upgradation, the telecom company will have to make an interactive voice response system (IVRS) call on the consumer's number and confirm whether he had requested the upgrade or not.
Department of Telecommunications (DoT) has added a new norm to the existing rules of SIM upgradation from 2G to 3G or 3G to 4G. Image source: Reuters
