    Can I keep my mobil number

      AvatarFinder
      MariamMay 9, 2025Finder

      Hi John, yes, you can keep your mobile number if it’s under your name. If it’s not, you’ll need to transfer the ownership to your name first. When you sign up, they’ll ask if you want to keep your existing number – just select ‘yes’ when prompted. Hope this helps!

    what is the difference between telstra normal and wholesale networks

      AvatarFinder
      MariamApril 22, 2025Finder

      Hi Grahame, Telstra’s main (retail) network covers around 99.5% of the population, including more remote areas. The wholesale network covers about 98.8%, so the difference is small but can matter if you’re in a more remote location. Hope this helps!

    Hi Aboud, You’re in the good place to start – if you’re after low-fuss text and talk, a 365-day plan is a good option. But if you’d prefer monthly payments, check out our guide to cheap mobile plans.

    I want a prepaid sim card (normal size) for the elevator phone, without an expiry date. Is this possible?

      AvatarFinder
      AngusOctober 22, 2024Finder

      Hi Fiona, Alas, I’m not aware of any SIM card that has no expiry – it’s always going to need a plan attached to it to be active, and 365 days is the longest you can get in Australia.
