Price increases take effect from today for Telstra and Boost Mobile's prepaid plans. 

Initially flagged back in July, the pricing of most prepaid plans from both providers has increased by $4. 

Telstra's seven-day expiry plan has seen a $1 increase, while its 28-day expiry plans have all gone up by $4 per month. Telstra's two long expiry plans have gone up by between $20 and $30 respectively – broken down into a monthly figure that's a $2.50 and $4 increase. All base data inclusions and speed caps for Telstra's prepaid plans remain the same.

Telstra is currently offering between 25 to 40GB of bonus data on its 28-day expiry plans for the first three recharges when you purchase a prepaid SIM and activate it by March 10, 2025. 

Here's a look at Telstra's prepaid plans with 28-day expiry:

While Boost Mobile is the only carrier that utilises the full Telstra network (covering 99.6% of Australians) the rest of the providers on the Telstra network still reach 98.8% of Australians – more than Optus or Vodafone.
