As stated by a representative of the Vietnam Posts and Telecommunications Group (VNPT), in this first turn, more than one million subscribers possessing the prefix 0124 will have their number changed to 084. Despite its positive result in the experimental phase, along with well-prepared technical solutions, in order to ensure a smooth convert, the company still mobilized nearly 300 technicians in 63 provinces and cities nationwide to cooperate in this task.
At the moment, any subscribers with the prefix 0124 (now changed to 084) are able to make phone calls and send messages to others in the same or other networks. These users need neither to change their SIM card nor re-register their personal information. The money in their account remains unchanged, and they do not have to do anything, but let VNPT carry out all necessary actions.
To quickly update and synchronize the contact book, customers of VNPT are suggested to wait until after October 7, 2018 when all network providers finish the conversion process.
VNPT also provides a useful tool named My VNPT for all mobile phone subscribers (even those of other network providers) to update new phone numbers with only a few simple steps. Besides, the company support its users to announce their new mobile phone numbers via delivering free messages to others in the same network, offering a low-price SMS package.
Regarding users of common phones, VNPT has already had a supporting plan to change via cable service or a piece of software installed on a personal computer.
