Why the price differs from the ad. Boost Mobile advertises this plan at $28.00 per 28 days — which is 13 charges a year, not 12. Spread across calendar months that works out to $30.44 a month.

Coverage
- Telstra retail reaches the largest land area of any Australian mobile network, which is why it is generally the strongest choice for regional and remote use.
- Coverage maps are predictive and show outdoor coverage only. Check your own address before switching.
Since 30 June 2026, Australian coverage maps must follow an ACMA standard, so the four coverage levels mean the same thing on every operator’s map.
