Love talking but don't want to be tied down to a contract? A prepaid plan can take care of that.
Why go prepaid for unlimited calls?
When telcos first started offering unlimited calls, they were generally tied into long-term contract plans. These days you really don't have to spend all that much if talking is your key smartphone use. A prepaid plan is ideal because you get unlimited calls plus whatever data quota your provider offers, together with complete control over your budget. Because you pay for the service upfront, you can't get hit with any kind of bill shock during your contract period. If you go over your data quota, depending on your provider, you should be able to buy more data or simply coast it out until your next recharge period by using free Wi-Fi services.
As well as keeping you on a budget, there are other situations where prepaid plans make good sense. If you have kids who like to spend a fair bit of time chatting or texting, they won't break your bank on a prepaid plan with unlimited calls and texts. For users who just want to talk and don't care about data, especially if they're using a simpler "feature phone" type device, these plans are also a good match. If you're happy with your existing handset and aren't locked into a contract, switching to prepaid can simply save you money on your existing contract charges.
What about unlimited data plans?
No telco in Australia offers unlimited data plans for mobile, although it is common for fixed-line broadband. What's more, this situation isn't likely to change.
