Phone companies are obliged to inform you if you're chewing through your mobile data allowance -- but an annoying quirk of the TCP Code means they only have to do so within 48 hours of it happening, by which point you can have wasted a lot of money on excess charges. Telstra is currently rolling out a system which will see those notifications apart near-instantly.
Telstra says that usage alerts indicating when you have used 50, 85 and 100 per cent of your allowance will now be sent "within seconds" of the usage occurring.
That change is being progressively rolled out to all consumer plans, a process Telstra says will be completed by November. (It introduced the alerts last July.) Telstra will also send an update for every $50 in excess data charges you incur.
Usage tracking in Telstra's 24x7 and My Telstra is also improving, though not quite as much. Data usage will now be updated every 15 minutes.
The bad news? This doesn't yet apply to business accounts, though Telstra says it is working on it.
