The Best 4G Modems for Mobile Broadband

Advertisement

More Australians are relying on home internet for work, school and entertainment – and broadband networks are feeling the strain. Both ADSL and NBN connections are undergoing extra pressure, across the network as a whole and within houses.

This congestion could be bad for you if you do lots of working from home, which is why it may be time to think about alternatives to the NBN, ADSL, or cable broadband. A key option that’s attracting frustrated NBN users is mobile broadband, a kind of internet connection that puts you on a separate network to your home broadband. Doing this could make your broadband service more reliable, but it’s important to think of it as an alternative to the NBN, especially as a backup.

But how does it work, and what technology does it use? In this article, we’ll be diving deep into the modems and devices you can use for mobile broadband to work.

What is mobile broadband?

Mobile broadband is internet which works through the 4G and (in some areas) 5G mobile networks across Australia that are owned by Telstra, Optus and Vodafone. These networks are completely separate from the NBN, and are typically intended for smartphones; however, telcos also offer these networks as an alternative to standard home internet, such as NBN or ADSL. The benefit of mobile broadband is that you can connect anywhere your provider offers mobile coverage, which means you can use your internet plan on-the-go and away from home.

There are plenty of different products that can be used for mobile broadband. Typically, mobile broadband is powered through a SIM card, given to you by the internet provider. After this is given to you, you can power it through a few different ways. It could be through a USB internet dongle, a mobile broadband modem, or it could simply be through your phone if you use your SIM card slot for the data-only SIM.

Should I get mobile broadband?

If there’s lots of strain on your internet at home because lots of people are using it, or if you need to move a lot or stay moving for work, mobile broadband could be a great fit for you. As a back-up plan or an immediate solution, there are plans on the market to fit all lifestyles.

What about 5G mobile broadband?

The 5G network is still being rolled out across Australia by the three major telcos, with Telstra and Optus providing coverage in spots in major cities and Vodafone now live in parts of western Sydney. Telstra is currently running an offer until June, where all mobile broadband plans include free access to 5G as well as 4G coverage, but you’ll need a device that can access the network. After the end of June, selected Telstra mobile broadband plans will continue to offer 5G coverage, while others can add 5G for an extra $15 per month.

Mobile Broadband Plans

Before we go any further on mobile broadband modems, check out the prices you can get mobile broadband for. Prices range between $15 for 7GB a month and $110 for 250GB a month, from a variety of different brands across all three phone networks. Some providers also allow you to sign up and get a device bundled in, like a modem or an internet dongle.

Optus Mobile Broadband Modems

Optus also offers a range of great devices to buy with your mobile broadband plan. In short, to get onto the internet, you’ll need a device that can either pick up a hotspot signal (such as a laptop) or a device that can have a SIM card inserted (such as a phone).

Optus has four mobile broadband modems up for grabs: the AC800S 4G WiFi Modem, the Alcatel Link Zone, the 4G USB Modem and the B818 4G WiFi Modem.

The AC800S 4G WiFi Modem is great if you’d like portable WiFi. It has a built-in battery, and it comes in a compact design. the Alcatel Link Zone is also a portable modem and has a built-in battery, but lacks the screen of the AC800S device. The 4G USB Modem is a dongle you can plug into your PC or laptop, and doesn’t have an inbuilt battery.

The B818 4G WiFi Modem on the other hand is a modem you must plug in to mains power. It has a strong antenna that provides strong home WiFi coverage, ideal for home usage, and can work well with numerous devices.

The B818 4G WiFI Modem has access to multiple 4G signal bands, meaning it’s better for multiple devices and users – whereas the AC800S 4G WiFi Modem being better at portable internet usage.

Both of these modems start at $65 per month (on 24 month plans), both requiring a 200GB or 500GB plan to be included with the purchase.

How fast is mobile broadband?

Typically, you should be able to reach download speeds of between 20Mbps and 100Mbps on a 4G connection, but faster download speeds of up to 1Gbps are now possible if you live in an area with 5G network coverage from your provider, and have a compatible device. Telstra currently offers 5G mobile broadband, which can be accessed through its Telstra 5G Wi-Fi Hub device.

That being said, mobile broadband speeds vary depending on which network you are on and what technology you are using. However, you should, at the very least, have speeds equivalent to what you’ll get on an NBN 12 plan.
