We already have to contend with a bewildering array of prepaid plans from major carriers, and Telstra calling its new offer Simplicity doesn't actually help with that. Call and text rates for the new plan are cheaper than Telstra's recent offers, but as ever, you need to check the details carefully.
Calls to Australian numbers (mobiles or landlines) cost 15 cents per minute or part thereoff, with no flagfall. Australian texts are 12 cents, while international texts are 20 cents. Calls to some international destinations are cheap -- 15 cents per minute to the UK or US -- but still potentially expensive for others. Data is also not particularly generous, at 10 cents per megabyte.
Telstra boasts that the new plan has extended expiry periods ($30 gets 60 days, $50 100 days and $100 180 days). That said, its existing Long Life option does rather better than that ($60 gets you a full year) if your main focus is an account that doesn't expire rather than one in active use.
