After contemplatinglegal action, it appears that Apple has acceded to TRAI’s demand and has finally approved theTRAI DNDapp which is now listed on the App Store. News of the app’s arrival on the App Store was confirmed by an Apple spokesperson toVentureBeat.
The registration process on the app is directly linked to a telecom operator’s customer support service and might take up to 7 days for a number to be registered and activate the DND feature. It must be noted that the app won’t block calls and messages from entities that users have subscribed to or whose services they actively use, such as their banking institution, cab-hailing service, food delivery apps, etc.
As for the reporting procedure, once users flag a call or SMS as spammy, the app will automatically create a complaint registration SMS that will be sent to the telecom operator on a toll-free number which is 1909.
