Brazilian fixed and mobile telephone users transferred their numbers across operators 4.54mn times last year, a 3.8% increase over 2009, according to ABR Telecom, the entity overseeing number portability in the country.
Subscribers have more frequently ported mobile numbers than fixed ones. Of the 8.04mn changes realized since the portability service launched in September 2008, 5.49mn (68%) have involved mobile lines, while 2.55mn (32%) pertained to fixed telephony.
In 4Q10, 64%, or 783,000, of the 1.23mn ports were of mobile numbers.
As in 2009 - the first year in which number portability was fully implemented across the country - December proved the most active month for mobile migrations in 2010. A record 300,000 cellular numbers changed carriers, as opposed to 296,000 in the last month of 2009.
In the fixed-line sector, a high-water mark was also recorded in December 2010, with 163,000 numbers transferred. August, conversely, was the hottest month for fixed-line ports in 2009, with 101,800.
Brazil boasts nearly 200mn telephone subscribers overall, according to the ABR Telecom website. The association's principal responsibilities include updating a national reference database for number portability, as well as working with telecom regulator Anatel and other industry players to assure transparency in the process.
