Telstra has suffered a fresh bout of outages on its mobile network the day before chief executive Andy Penn faces investors in a crucial chance to outline a new and sustainable strategy for the telco giant.
Thousands of customers on mobile reseller services using Telstra's network were affected by outages from Monday night, with a Telstra spokesperson saying most problems had been resolved by Tuesday afternoon.
According to Telstra's website, outages caused intermittent mobile service in Sydney, Melbourne, Brisbane, Adelaide and Hobart.
Telstra said there was no issue for its own customers on 3G or 4G networks but a "vendor platform issue" had affected reseller services for "a small number of wholesale customers".
The latest problem comes less than 24 hours before Mr Penn fronts investors in Sydney at the company's annual strategy briefing day.
With Telstra shares hovering around a seven-year low of $2.87, Mr Penn is under growing pressure to provide a vision to secure the company's growth as it faces thinner margins and tougher competition in the Australian market.
Since Mr Penn took over as CEO in May, 2015, Telstra shares have fallen 53.8 per cent.
Last month Telstra warned that its 2017/18 earnings are likely to be at the bottom end of its guidance range of $10.1 billion to $10.6 billion, blaming increasing competition in mobile and fixed broadband, and rising costs from the NBN.
In August the telco sparked a share rout and investor outcry when it ended its longstanding policy of paying almost 100 per cent of underlying profit in dividends, shifting instead to a range of 70 to 90 per cent.
Analysts have tipped further cost cuts will be announced and some have raised the possibility of a major announcement such as a split of the company's network and retail operations into separate businesses.
