Zimbabwe’s smallest mobile operator Telecel, part of the Orascom Telecom group, is to release 100,000 new lines on the market this week, reports AllAfrica.com. The GSM provider’s public relations officer Monica Malunda said the additional connections had been made available following a network capacity upgrade carried out six weeks ago, and would increase Telecel’s subscriber base to about 350,000. She added that upgrading work was being carried out in two phases, the first targeting Harare and Bulawayo, with the second phase expected to start soon. In further efforts to catch up larger GSM rivals Econet and NetOne in terms of coverage, the second part of the expansion would target most main roads, ‘service centres’ and rural areas and would see more lines being released on the market. Earlier this month Econet released 50,000 new pre-paid GSM lines following network capacity upgrades.
