There’s nothing quite as frustrating as a text from your telco to say “you’ve now used 100% of your data limit”.
Unless you’ve got data banked up chances are you’ve just triggered an automatic top-up or excess data charge. Some providers charge $10 for an extra 2GB. Nearly half the price of the plan itself. Yeesh.
If you’ve felt the sting a few too many times then it might be worth switching to a plan with more data or giving an unlimited data mobile plan a whirl.

Just a handful exist and they still have a monthly data allowance. but rather than charging you for more data, your speeds are slowed down instead (usually to just a 1-2 Mbps). That’s enough for basic browsing and to last you until your next billing cycle.
Let’s take a look at some of the providers who have unlimited data mobile plans.
felix unlimited data mobile plans
We’ll get felix out of the way first as it’s a bit of a special case. felix is the only telco in Australia with a truly unlimited data mobile plan in the sense that you get the same maximum 20Mbps speed each month regardless of how much data you use. That’s slightly lower than an NBN 25 plan.
Its other plans have speeds capped at 150Mbps while you still have a data allowance but they’ll be throttled to 1.5Mbps if you use it up.
