Telstra has apologised for an outage that left thousands of NSW mobile phone customers unable to send or receive calls.

Telstra tweeted to customers at around 5.45am that it was "experiencing some issues with the ADSL network in NSW at the moment" and was working to resolve the situation "asap".

The network was restored just after 6am on Tuesday and the telco has apologised to its customers for the inconvenience, which was caused by maintenance repairs that took longer than expected.
