    Optus have offered, on a 24 month plan, a new iPhone 7 with unlimited text and national calls together with 10GB of data discounted to $45.20 per month. Is this a good deal?

    Hi,
    I would like to know which MVNO using full strength 4G network for voice and data. I heard that Boost is using Telstra’s full network and Virgin is using Optus. Is there any other MVNO using full strength network for both voice and data ??
    Cheers!
    Samy

      Hi Samy,

      Thanks for getting in touch with Finder.

      The network strength depends on different factors such as time and place. However, in terms of network coverage, the service an MVNO offers shouldn’t differ in any way at all from the service that you’d get from the underlying network provider at the same location. That makes sense because it’s the exact same network infrastructure. If there’s an outage or a reception problem with an MVNO, it’s a question of the underlying carrier’s network, not the MVNO.

      We also have a list of MVNOs along with the networks they use. Please check and see if it answers your question.

      I hope this helps. Should you have further questions, please don’t hesitate to reach out again.

      Have a wonderful day!

      Cheers,
      Joshua

    I need a new mobile phone (keeping my existing mobile number) + prepaid monthly plan to receive incoming calls from work and reply back fast and easy … as my job based on how fast I receive the messages from work and can take the shift … so coverage is important … between Caboolture, the Sunshine Coast and Bribie Island . Best/lowest price deals with fast and safe/reliable network even in rain/storm? Any suggestions? Thanks*

      Hi Zita,

      Thanks for your inquiry.

      In terms of speed, calls, and messaging, all Australian telcos are largely using 3G networks. So we couldn’t single out who’s fast and who’s not. You may compare your phone plan using our comparison table and search filters to help narrow down your options. Please see the image below:

      Mobile plan+phone

      Once you have chosen a particular plan, you may then click on the “Go to site” button and you will be redirected to the provider’s website where you can proceed with your application or get in touch with their representatives for further assistance.

      Hope this helps.

      Cheers,
      May
