How do I choose the best cheap phone plan for me?

Firstly, consider what your needs are. Of course a cheap plan is great, but if you know the inclusions won’t cut it for how much data you use, then it’s probably not going to be the right plan for you. If you happen to already have other services with Optus, such as an NBN plan, you might be able to pick up a discount if you bundle, but you should always check with the provider before signing up. The entertainment bonuses from Optus are also fairly generous, and having access to the Optus 5G network on all plans at no extra cost, is a big plus.

If you’re on a super tight budget, there are plenty of cheap phone plans out there, but be mindful of what is included. Some plans might run on a short expiry period if it’s prepaid, while other plans might have limited minutes on calls or tiny data inclusions. Consider how much data you’ll need, and compare plans with a similar amount to see how much you can get for your money.
