Unlimited Internet plans eliminate data restrictions, allowing you to surf, stream, and work on the web without constantly monitoring your usage.

For heavy Internet users, unlimited Internet is the ideal choice and most Internet providers now offer unlimited Internet plans as standard. The freedom from data caps can save you money in the long run, too.

The only issue is those upfront costs to pay for, whether these are sign-up or modem costs. Most providers offer free modems on certain speed tiers which saves you money and we can help you find them.

In this quick guide, we will go through the most popular unlimited Internet plans with no upfront cost in our database.

What are the best unlimited Internet plans with no upfront cost?

Finding the best unlimited Internet plan can be confusing if you aren’t sure where to begin and it can be even harder to choose an unlimited plan without any upfront costs. 

We've narrowed your options to the best unlimited Internet plans with zero upfront costs available today.

Which is the best unlimited NBN 50 plan with no upfront cost?

Unlimited Internet plans run from NBN 25 NBN 1000, but NBN 50 stands out as the most popular unlimited Internet plan choice. 

This plan delivers an impressive average typical evening speed of 50 Mbps. Plus, many providers offer enticing perks like bundling your mobile plan to trim your monthly expenses. You can enjoy savings without sacrificing speed, even if multiple users are online at once.

Here are our top picks for the best NBN 50 plans with unlimited data and no upfront costs:

Optus

Optus offers a variety of Internet plans, and it was early to offer unlimited data across NBN plans. The NBN 50 plan delivers speeds up to 50Mbps, suitable for general web use, streaming, and online gaming.

Why choose Optus for unlimited NBN plans? Optus keeps its plan options simple, making it easy to find what you need. There is a modem included in their plan with no connection fees, too, making it easy to choose Optus NBN 50.

Although the starting prices are a bit higher than some competitors, Optus offers bonuses like 4G backup and an Optus Sport subscription.

Which unlimited high-speed Internet plan should I pick?

If you find yourself frequently downloading hefty files, indulging in 4K movie streaming, or battling high-ping rates in online gaming, then a high-speed connection is precisely what you need. NBN100 plans, boasting speeds of up to 100Mbps in the evening, can easily meet the demands of most users.

Providers take various approaches with NBN 100, offering it either as an enhancement to the base NBN 50 plans or as a standalone service. Most of the providers that offer NBN 100 will offer a free modem in exchange for a slightly higher monthly cost.

For those who demand even more horsepower than the NBN 100, providers also offer speed tiers of 250, 500, and 1000, ideal for power-users seeking heavy-duty speeds for gaming and streaming.

Compare unlimited Internet plans with no upfront cost with Compare Broadband

Price is a key factor when choosing an Internet plan, but cheaper plans often come with slower speeds. You might find that the cheapest plan isn't always the better option, either! Often, a higher monthly cost is the exchange for a free modem and no upfront costs.

NBN 12 and NBN 25 plans are okay for 1-2 people with basic needs but not great for larger families, especially if some work or study from home or do a lot of streaming.

For bigger families with many devices, NBN 50 and NBN 100 plans are better. These plans provide the speed needed for video conferences, big downloads, and 4K streaming.

While a low-cost plan might seem attractive, consider your speed needs and the provider's reputation.

At Compare Broadband, we understand that finding the right NBN plan can be overwhelming. Our broadband experts are here to help you. Give us a call at 1300 764 000, and we'll guide you through the process.
