The MIC said landline subscribers were estimated at 7 million in June, down from 9.47 million in June 2013.
At the same time last year, the number of mobile subscribers was around 136 million.
According to the MIC, the number of mobile subscribers using data services was estimated at 121 million in June, down about 2 million from the beginning of the year.
It is predicted that landline numbers will continue to drop in the future as users are lured to cheaper mobile devices and more reasonably priced mobile plans.
As of June, Vietnam had added 300,000 new broadband ADSL subscribers compared with a year earlier, raising the total above 5.5 million.
In the first half of 2014, revenue from postal and telecommunications services was estimated at VND 122 trillion (US$5.7 billion), equivalent to 44% of the sector’s target for the whole of 2014.
