Mobile phone service provider VinaPhone today said it has ceased providing text messaging copy services in a bid to preserve the privacy of its subscribers.
SMS copy, a sub service of its SMS Plus programme, allows VinaPhone subscribers to automatically copy a text message from a mobile number to another number.
Subscribers needed to register to use the service.
VinaPhone, which has 30 million users, said customers had raised complaints about privacy.
VinaPhone, a member of State-owned VNPT (Vietnam Post and Telecommunications Group), is continuing to provide other services deemed to be controversial, such as family tracker, which allows a subscriber to track the location of another subscriber online.
SMS text messaging is the most widely used data application in the world, with over 3.7 billion active users, or 74 per cent of all mobile phone subscribers, world wide, according to the GSM Association
The Ministry of Information and Communications said there were 134.2 million telephone subscribers in Vietnam, of which 119 million are mobile phone subscriptions and 15.3 million landline subscriptions.
