The Ho Chi Minh City government has ordered the suspension of 114,352 pre-paid mobile subscriptions registered with false information with the military-run provider Viettel.
This is the second time since December 28 Viettel was asked to suspend its service to falsely registered subscribers, news website VnExpress reported.
In the first time, 37,000 subscribers were suspended, including 23,000 from Viettel plus others from MobiFone and Vinaphone, the two telecommunication service providers of Vietnam Post and Telecommunication Group.
Each of the providers was fined VND30 million (US$1,425) that time. The three are major providers of mobile phone service in Vietnam.
The city government has asked other telecommunication service providers to check the registration of their pre-paid customers in the city, before they are checked.
A government order issued in 2009 requires pre-paid mobile subscribers to register their personal information including names, date of birth, and ID or passport number to their providers by the end of the year.
The providers were required to continue requesting information from new subscribers.
However, the order has not been followed, with promotion SIM cards sold widely on the market.
One customer can own a dozen phone numbers without giving out any personal information.
The cards, also known as spam SIM, are usually sold for three to four times less than the money on the card.
