Expert guide: Southern Phone mobile phone plans

Southern Phone has been operating since 2002, offering a range of personal and business telecommunications services throughout Australia with its main focus on regional communities.

While Southern Phone was initially owned by a group of local councils after landing some government funding, in 2019 the company was bought by energy supplier AGL. It offers a simple range of phone plans on the Optus network, although the telco had previously also offered plans on the Telstra network.

So just what does Southern Phone have to offer when it comes to mobile phone plans? In this Southern Phone review, we’ll take a look at what you can expect when it comes to plans, prices and overall value for money.

Services offered

Southern Phone offers a range of mobile phone plans, with its core group of SIM-only postpaid plans, the option of buying a phone on a plan, along with 5G SIM-only plans.

Its selection of mobile phones is rather small, compared to other telcos, and it mostly offers Samsung phones. However, if you’re after a simple phone and a simple phone plan, and want to avoid the big telcos, you might find the right option for you.

Network and coverage

Using the Optus 3G, 4G and 5G networks means that Southern Phone can reach around 98.5% of the population. Optus has also committed to building more towers and expanding its coverage to regional areas as part of the Australian Government’s Mobile Black Spot Program. This means more regional areas should see stronger and more consistent mobile coverage.

For 5G plans, keep in mind that 5G is only available in selected areas, and Southern Phone states it is currently unavailable in Tasmania and the NT. To check the network coverage in your area, visit the Southern Phone website.

Special features and bonuses

Southern Phone keeps phone plans simple, but there are plenty of choices when it comes to postpaid plans and plans with handsets.

  • Unlimited national calls and SMS: All of Southern Phone’s plans come with unlimited standard national calls and SMS. This is great news if you don’t use much data, as you can opt for a lower plan without being restricted on calls and text.
  • 5G phone plans: There are four SIM-only 5G phone plans available, making Southern Phone one of the few MVNOs to offer 5G phone plans.
  • International calls: Several plans include a set amount of international call credit, starting at $50 and going up to $500 on select plans.
  • Phones on plans: As one of the few smaller telcos offering mobile handsets with plans, Southern Phone is a good option if you want a new device, but don’t want to pay the prices charged by the big three telcos. You can also buy a smartphone outright with Southern Phone and then bundle with a plan, which isn’t often available through other telcos.

Southern Phone FAQs

Who owns Southern Phone?

Southern Phone was initially owned by local councils and was launched in 2002 after receiving funding from the Australian Government’s Networking the Nation scheme. Its focus was on providing telecommunication services to regional and remote parts of the country.

In 2019, Southern Phone was acquired by AGL Energy, and is now a 100% owned subsidiary of AGL. Despite changing ownership, Southern Phone still has a strong focus on regional communities, and has offices in Moruya, Bendigo and Melbourne.

How do I pay my Southern Phone bill?

You can either pay your bill via the Southern Phone website, via direct debit, or through your preferred banking service, such as BPay. If you wish to set up direct debit, you can either log into your account on the Southern Phone website, or call their customer support to set it up.

Is Southern Phone a good deal?

If you’re looking for simple postpaid phone plans with decent talk, text and data inclusions, Southern Phone does have some good options to choose from, especially if you’re looking for a new handset. But it’s important to do your research before jumping into a new plan. If you live outside of the major cities, you might find there are more providers available, which gives you even more choice than ever.
