For those with patchy WiFi at home or who are constantly working on their iPad or tablet throughout the day on the go, you might want to consider getting mobile broadband. Let’s take a look at our round-up of the best mobile broadband plans, but first, we’ll explain how it all works.

What is mobile broadband?
Info Box

There are four types of mobile broadband: data only SIM (no modem required), pocket WiFi (4G WiFi modem), USB modem and home wireless (5G modem). The type you’ll want to choose will depend on how many devices you want to connect, whether you want it plugged directly into your power outlet at home or to insert straight into your laptop or tablet.

For those wanting mobile broadband on the go, it would suit most users to either pick a data SIM for their iPad/tablet or a pocket WiFi modem to connect multiple devices while you’re out. For just plugging into a single laptop, consider a 4G USB modem, unless you have a laptop with a SIM card. If you’re at home, consider getting home wireless internet.

Best mobile broadband plan overall

Belong 400GB Data SIM Only

pro
Pros
pro Excellent dollar-to-data value
pro 400GB monthly data
con
Cons
con No modem options available at Belong
con Capped speeds

If you’re looking for the best dollar-for-data deal, there’s no going past Belong's 400GB mobile broadband plan. It has one of the largest mobile broadband plans out, and charges a surprisingly affordable $70 per month.

That works out to be roughly 17 cents per gigabyte. 

This plan is subject to speed caps, however. You're limited to speeds of 180Mbps on 4G, and 250Mbps on 5G. If you go over your data allowance, you'll be capped to 1Mbps, but won't pay extra fees. 

You'll also need to bring your own portable hotspot, dongle, or tablet. Belong doesn't sell any devices to go with its mobile broadband plans. 

Here's how Belong's plan compares to other popular options with at least 50GB:

What is the best mobile internet in Australia?
Pin
The best mobile internet in Australia is determined by what you’re after: value, speed or coverage. For value, cheaper plans tend to offer less data but the better mobile broadband deals are those that offer more gigabytes per dollar spent. For speed, 5G is the fastest but 4G is more readily accessible. Whichever network you receive the best signal strength with, relative to where you live, work and/or play using mobile broadband will determine the best speeds. As for coverage, Telstra has the best coverage (including Telstra 5G), followed by Optus, then Vodafone.

Best Optus mobile broadband plan

$60 Optus Choice Plus Data Plan

pro
Pros
pro No excess data charges
pro Discounted Optus Sport access
con
Cons
con Comparatively low data allowance
con Only one modem option

It doesn’t have as much data as it used to, but the $60 Optus Choice Plus Data Plan is still a good deal. You’ll pay $60 a month for 100GB of data, which works out to around 23GB per week. If you go over, speeds are capped at 1.5Mbps, which means no excess data charges. This Optus plan can you get discounted access to Optus Sport + OS Fitness. You'll pay $6.99 per month instead of the full $24.99 per month. 

Optus lets you choose between bringing your own modem or you can pay off a 5G Portable WiFi modem for $434.88, split across either 12, 24 or 36 months. This Optus mobile broadband modem has 5G capability, can connect up to 32 devices and has a 4,500mAh battery for up to nine hours of use.

Best Telstra mobile broadband plan

Upfront Data Plan Large

pro
Pros
pro 400GB monthly data
pro No excess data charges
con
Cons
con More expensive than competition

Telstra’s Upfront Data Plan Large provides a massive 400GB for $85 monthly fee. Like Optus, Telstra caps speeds for its non-prepaid mobile broadband plans at 1.5Mbps if you go over. Still, that 400GB monthly cap works out to a very respectable 92GB of data per week.

Another plus is you’ll get access to Telstra’s expanding 5G network as well as data-free Apple Music.

You can also share your data with up to 10 eligible Upfront services on the same account, which is great if you're already a Telstra customer. 

Should you BYO modem or pick a modem bundle?
Info Box
While you can opt to bring your own modem, be sure that you choose a compatible handset that supports 3G 850MHz, 4G 1800Mhz and 4G 700Mhz as well as 5G 3500MHz bandwidth.

Telstra also has $15 Extra Small, $25 Small and $55 Medium mobile broadband plans (in addition to a few prepaid options), so if you find you aren’t finishing your data balance at the end of the month, you can always consider switching to a lower data plan.

If you don’t already have a modem, you can purchase one through Telstra.

These start at $99 for a 4G-ready dongle, or at $399.88 if you want 5G connectivity. Any Telstra mobile broadband modem can be paid off over 12, 24 or 36 months.

Telstra also has more affordable 4G prepaid dongle and hotspot options. 

Here are more popular SIM-only Upfront Telstra mobile broadband plans:

Best Vodafone mobile broadband plan

Vodafone has a knack for throwing in bonus data with its SIM Only mobile plans, and its mobile broadband plans are also part of this trend. You’ll find the best value from the Vodafone 100GB SIM Only Modem Plan, which costs $60 a month for 150GB of data (including a regularly extended 50GB of bonus data).

Unlike Optus and Telstra, Vodafone charges $10 per extra gigabyte if you go over your monthly allowance.

Assuming Vodafone continues its bonus-data trend, the best cheap mobile data plan in terms of dollar-to-data value is the Vodafone 10GB Red Mobile Plan. For $20 a month, you get 10GB of base data and 20GB of bonus data, which works out to 6.9GB of data per week. 

Here are more popular mobile broadband plans under $30 per month:

Best prepaid mobile broadband plan

amaysim 90GB Data Plan

pro
Pros
pro No risk of excess fees
con
Cons
con Comparatively small data allowance
con 28-day expiry means one extra top-up per year

amaysim’s 90GB Data Plan offers the most data and best value for a prepaid plan and comes in at $60 per month, even though it’s a 28-day plan, which means you’ll have to recharge one extra time if you keep it for a year. You’ll also have to BYO your own modem or SIM card-compatible laptop or tablet, but you won’t have to worry about excess data charges.

If 90GB is too much for your usage, amaysim also offers 7GB for $15 or 50GB for $40. 

amaysim is powered by the Optus 4G network.

How does mobile broadband work?

Mobile broadband works in the same way that internet on your mobile phone operates. You need to be in range of a mobile tower on the network your telco uses to offer mobile broadband, which will be either Telstra, Optus or Vodafone. Like a mobile phone, the strength of the mobile broadband signal will determine overall download and upload speeds.

Most plans are offered on the respective 4G mobile networks of Australia, which means downloads can theoretically reach as fast as 100Mbps and up to 50Mbps upload. In reality, speeds are likely to be noticeably slower, as a number of factors come into play, including reception strength and the level of congestion on the mobile tower your internet connection is using.

Now with the theory out of the way, there are heaps of plans to pick from; so, which is right for your needs?

Looking for 5G mobile broadband?
Light Bulb
If you're feeling the need for speed, you’ll be happy to know that Telstra and Optus have already begun rolling out 5G mobile broadband plans. For more information on these plans and how they work, read our dedicated 5G modem guide. Alternatively, have a look at everything you need to know about 5G home internet.

How to find the best mobile broadband plan

Essentially, before picking a mobile broadband plan, you’ll need to ask yourself the following questions:

If you do, move on to question two. If you don’t, you’ll need to either source one yourself or pick a mobile broadband plan with a modem included. Ensure you pick a compatible device that supports 3G 850MHz, 4G 1800Mhz and 4G 700Mhz, or 5G 3500MHz bandwidth if you’re in an area with 5G coverage and have a 5G mobile broadband plan. Here are some examples of available 4G WiFi modems and USB modems that offer free shipping from Amazon Australia.

If you’re a light data user, 20GB to 30GB per month should be more than enough for most people to satisfy your streaming and browsing needs. For heavy data users, wanting to stream videos in 4K or who are using your device for work all day, you’ll probably want to look at plans from at least 60GB up per month.

Check whether the provider you’re considering has good coverage in the areas where you want to use mobile broadband. The interactive map below will help. If you’re already with a provider, look out for any bundle deals they may be offering, or you might want to stick with the same provider to make life easier.

If you’re unsure about committing to a mobile broadband plan right now, it’d be wiser to stick with a month-to-month plan for the moment. If you don’t mind committing, you might be able to save yourself some dollars by picking a 12-month contract plan.

For example, if you’re keen to get data-free or a free subscription to Apple Music or for sports streaming, you might want to pick Telstra or Optus for such perks which most MVNOs don’t offer.

Mobile broadband pros and cons

If you're on the fence about mobile broadband, here are some of the main pros and cons. 

pro
Pros
pro Typically contract-free
pro Works instantly - no professional installation required
pro Mobile networks can be faster than the NBN
pro Modems tend to be battery powered
con
Cons
con Modems always cost extra
con Smaller data allowances than NBN
con Mobile networks are more prone to congestion than NBN

We'd recommend mobile broadband for on-the-go usage or a dedicated SIM in a tablet or laptop, rather than replacing a home internet connection. 

Telstra and Belong's 400GB mobile broadband plans could be enough for a primary internet connection for some users, however. 

FAQ

You can't get an unlimited mobile broadband with an unlimited data allowance in the same way you can an NBN plan.

Mobile broadband plans from Telstra, Optus, and Belong are however free from excess charges, so could be considered unlimited in a way, similar to mobile plans from these providers. 

Instead of paying for extra data when you go over your allowance on one of these mobile broadband plans, you'll instead keep using your connection at a slower speed. 1.5Mbps on Telstra and Optus, and 1Mbps on Belong. 

While these kinds of speeds are okay on mobile, they'll almost certainly be too slow if you're using your mobile broadband connection with a computer.

In many cases, mobile broadband plans will run at uncapped 4G or 5G network speeds. This will depend on your coverage and congestion, but it's safe to expect at least 50Mbps from a 4G mobile broadband plan, and over 200Mbps on a 5G mobile broadband plan.

Some mobile broadband plans - such as those from Belong - have speed caps, however.

A large number of providers offer mobile broadband. These include the following: 

  • Telstra
  • Optus
  • Vodafone
  • Belong
  • Aussie Broadband
  • SpinTel
  • Kogan
  • ALDI Mobile
  • amaysim

If you take up a mobile broadband plan, you'll need somewhere to stick your SIM.

Mobile broadband SIMs can be used in almost any device. The simplest solution is buying a portable modem (also known as a Pocket WiFi). Major telcos like Telstra, Optus, and Vodafone offer these alongside their plans. 

Alternatively, you can buy a portable modem unlocked and outright, like this D-Link model on Amazon.

Mobile broadband SIMs can also be used in a tablet or laptop, if your device has a SIM slot. 

Most mobile broadband SIMs can also be used in a phone. This means you can always take an old phone and turn it into a personal hotspot.
