Southern Phone review: Our verdict

Southern Phone plans are actually pretty good value, especially with the discounts they are offering for the first 6-months of service. As a provider they meet a lot of different segments needs. It also offers carbon neutral plans for those more environmentally conscious and have dedicate senior hub on their site to help older Australians with their mobile needs.

Other reasons you might like Southern Phone are that:

  • You can worry less about your phone's impact on the environment since all of Southern Phone's plans are 100% carbon neutral.
  • Support section for seniors through dedicated products and plans.

But you might be concerned that:

  • There are no international roaming options, meaning you can't take your plan overseas.
  • You'll only get access to talk, text and data – some plans do have international call credit but otherwise there are no bonus features on Southern Phone's plans.

Our expert says

"I took out a SIM card from Southern Phone because of the $9/month for 20GB deal. I also like that you get $50 towards int'l phone calls as that means I get roughly 150 minutes to call the US if I can't connect via WhatsApp or FaceTime."

    What constitutes “data” in regard to mobile phones?

      JonathanJune 8, 2017

      Hi Dennis!

      Thanks for the comment.

      Data is the exchange of information from the internet and your device or its applications. Whenever you turn-on your “data”, you are connected to the network and download or upload information. This includes emails, chat, browsing, internet banking, using voice over internet apps and many more.

      You may contact your network by calling their hotline for further details on how you can manage your data.

      Hope this clarifies.

      Cheers,
      Jonathan

    I’m trying to finalise my plan but my mobile cut out. I have rang three times in an attempt to complete my application (which is on your computer file), but to no avail. Don’t email me.

      Hi norm p.

      You’ve reached finder, not Southern Phone telco. I would recommend contacting Southern Cross on 1300 019 408.

      Cheers,
      Brodie
