Haiphong Post and Telecommunication Company (HPTC) is the sole state agency responsible for the telecommunication service. In March 2003, HPTC has started the construction of a Post Office covering 1000 m2 at the Utilities area of DVIZ to serve the telecommunication need of investors in the zone.

On 24/9/2003, the HPTC started to supply advanced telematics services in the DVIZ. These services include high speed ADSL Internet connection (able to respond to subscribers at maximal 3.5 km distance from the exchange) as well as service of hiring separate channels: 64kb/s, 2Mb/s, etc.... Proconco was very happy to become the first client of HP Post Office in DVIZ to enjoy the new ADSL communication service.
