Benefits of the transformation from 0165 to the new prefix

Not only Viettel but all network providers are required to switch to new prefixes. So why is it necessary to convert mobile phone prefixes? According to the Ministry of Information and Communications, the conversion to new prefixes will bring about the following benefits:

Enhances flexibility for the number pool of all network providers: To meet the long-term development trends of telecommunications, the conversion to new prefixes is essential to increase the number of subscribers for network providers. After the conversion, it is estimated that over 1 billion new subscribers will be added to the number pool.

Shortens numbers for easier memorization: Converting the initial 4 digits to 3 digits makes mobile numbers shorter, reducing them from 11 to 10 digits. Therefore, memorizing phone numbers becomes easier than before. Simultaneously, many subscribers suddenly have attractive numbers when transitioning to 10 digits, enhancing the value of phone numbers for network providers.

Reducing spam SIMs: According to the Ministry of Information and Communications, 11-digit subscriptions are often used for advertising and marketing. After transitioning to 10 digits, the spam SIM rate will decrease, enhancing the user experience.
