számhordozást

Számhordozás, also known as number portability, is a telecommunications service that allows consumers to keep their existing phone numbers when switching to a different network provider. This service is available for both mobile and landline numbers. The process typically involves a request from the customer to their new provider, who then initiates the transfer with the old provider.

The primary benefit of számhordozás is consumer choice and competition. Without it, users would be reluctant to change providers due to the inconvenience of losing their established phone number. Number portability facilitates a more competitive market by removing a significant barrier to switching.

The technical implementation of számhordozás varies by country and region, but generally involves a central database that maps ported numbers to their current network. When a call is made to a ported number, the network queries this database to determine the correct destination. The duration of the porting process can also vary, but it is often completed within a few business days.

Számhordozás has been widely adopted globally and is considered a fundamental service for modern telecommunications. It empowers consumers, encourages innovation among providers, and contributes to a dynamic and responsive market. The service is usually free of charge for the end-user, with the costs borne by the providers.
