On 01.07.2003 was marked in CDMA mobile network in Vietnam, the first named S-Fone officially a technology partner from South Korea and SPT for a period of 15 years. At that time, S-Fone is network revenue per subscriber highest in the mobile network. Many people had expected the appearance of cellular CDMA technology with the unique slogan "Play is the" S-Fone will soon ... made about the Vietnamese mobile market.
However, actual implementation is not so. Originally the brand was built by the two partners had "collectively fight back hard" as SPT and SK Telecom, however, until 2010 SK Telecom has announced withdrawal from the project S-Fone term cooperation although not all. After the retreat of the Korean partner, S-Fone has struggled to develop in the context of Vietnamese mobile market fierce competition on a network with 7 all.
Quiet operation for a long time, recently, there have been reports that SPT is developing a revolutionary plan, will death to switch to CDMA technology for 3G HSPA 800 MHz. However, until this point, still does not have a leader of SPT or S-Fone officially confirm the report.
However, in many telecommunications experts, at this point, this is a job to do of SPT with S-Fone to be able to maintain this network 095. Difficulties in the capital infrastructure, network development, but the toughest part of S-Fone is the terminal that is "a market alone," the market should not attract customers. If the move to 3G technology, these difficulties will be resolved.
Song, in fact, if carefully planned, the conversion technology of CDMA cellular networks is 9 years old this life more difficult, especially costly problem. Because if technology changes, S-Fone to replace almost the entire radio network and take advantage of some basic parts like transmission, the station only.
In addition to new investment in 3G networks, S-Fone also have to replace CDMA phone customers are still using the service, this number is now not millions but do little. S-Fone will have to spend several hundred million dollars for the "new blood" and although most urgently, it must be 2013, the new S-Fone resolved this issue.
There was time, the Vietnamese mobile market witnessed two "sides" to provide technology services in Vietnam to the world "leg braces": GSM has VinaPhone, MobiFone, Viettel and S-CDMA is Fone, HT Mobile and EVN Telecom.
However, HT Mobile after less than a year to provide CDMA services also had to re-calculate the "move" with the application of technology transfer to EGSM. 15/12/2008, Hanoi Telecom filed for adjustment and technological transformation project of HT Mobile network from CDMA to EGSM. Then start the conversion Hanoi Telecom HT Mobile subscribers to S-Fone network.
On 09/04/2009, HT Mobile has officially returned to service in Vietnam with Vietnamobile brand new, GSM technology. The "makeover" has been assessed earlier Hanoi Telecom (Vietnamobile network managing unit) and Hutchison partners reacted quickly to look for before the end sooner or later the CDMA technology.
Even EVN Telecom, which is strongly backed by the parent company, the Electricity of Vietnam came into the mobile market with CDMA technology in 2005, from 01.01.2012 has no brand again that the "hand over the status quo" for Viettel to pile up after a loss. When no longer EVN Telecom, the subscriber's existing business has been "imported" to Viettel, Viettel air waves.
And now, to turn the S-Fone with inaccurate information though, will change into a 3G CDMA technology. If technological transformation project of the S-Fone is true, that means, CDMA will no longer "of the living 'in Vietnam.
