MUMBAI: TRAI has launched five apps including -- MyCall, MySpeed and Do Not Disturb (DND 2.0) — to help subscribers assess call and data quality, and has sent an advisory to telcos to offer one-year data packs -- only. Besides, TRAI has also upgraded its 'Do Not Disturb' app with additional new features like an intelligent spam detection engine and updates about action taken on complaints within the app.

"The application MyCall will help mobile phone users rate their experience about voice call quality in real-time and help TRAI gather customer experience data along with network data," TRAI said in a statement.

The regulator and government have refused to lower their guard on the subject of call drops, and have kept a close watch on call quality through initiatives such as automated call system and drive tests.

TRAI has also launched an update to its MySpeed app, which allows customers to measure 3G/4G data speeds and send the results to the regulator.

The regulator said it has sent an advisory to all telecom operators asking them to launch at least one pack (special tariff voucher or STV) of data services with a validity of 365 days. The advisory comes after operators’ requested TRAI last year for longer validity for STVs with only data benefits, for certain category of consumers who prefer lower denomination data packs with longer validity.
