The total number of mobile phones in Armenia dropped in the three months to 30 September 2011, according to Samvel Arabajyan, a committee member of national telecoms regulator, the Commission on Regulation of Public Services (PSRC). However, Arabajyan confirmed that the drop is related to a change in the way two cellcos – VivaCell-MTS and Orange Armenia – changed their methodology for counting ‘active’ subscribers, rather than a mass switch-off from end users. The operators’ decision to alter the way they count subscribers wiped more than half a million off the total in the three-month period, down to 3.27 million, he said. VivaCell removed around 450,000 from its total, down to 2.06 million, while Orange trimmed its base to 520,000. ArmenTel meanwhile, has not changed the way it calculates its subscribers: it ended the third quarter with 750,000 lines, up from 733,000 in June.
