    I am using only 65GB for 365 days! Which plan or company should I use?
    I will prefer Telstra as the provider from the company chosen. Like Boost or Aldi.
    Thank you

      Hi Michel, unfortunately, you’ll be hard pressed to find a 365-day plan on the Telstra network for low data use. Your options include ALDI Mobile, Everyday Mobile and Boost Mobile. If you’re happy to expand to perhaps the Optus network, you can find some cheaper offers here: https://www.finder.com.au/mobile-plans/prepaid-plans/best-long-expiry-prepaid-plans. Hope this helps!

    Will the cover still be usable if you have had to give the loaned phone back before the 365 day is up

      Hi Lyndsay, as long as you have the physical SIM with you then yes, you can use the plan on another device. Hope this helps!

    a) what happens if you dont have the phone number anymore some months into the plan.
    b) whats an low average of data required per day
    c) the phone sim is required to colect calls/text messages, as I need another phone number whilst i up date my new one (Due to Scams on my exsiting mobile number)

      Mariam Gabaji's headshotFinder
      MariamOctober 3, 2025Finder

      Hi Lyndsay, I’ll attempt to answer your queries but I may require more details:

      a) Are you still paying for the number you don’t have anymore or did you stop using it and aren’t paying? If it’s the latter, then that means the number is inactive and after 6-12 months the provider can recycle it and pass it on to someone else.
      b) According to our research Aussies use around 13-15GB of data a month so that’s about 500MB a day.
      c) I’m unsure of your last comment but you can get a new number by comparing mobile plans on Finder based on your budget and how much data you need: https://www.finder.com.au/mobile-plans.

      Hope this helps!

    I am interested in purchasing the Lycamobile Large Plan SIM ($175 for 600GB) during the current promotion. I read in the Critical Information Summary that the SIM must be activated within 30 days of purchase (or by the promotional deadline).

    Do you know If I purchase the SIM before the promotion ends, but only activate it after the promotion period has finished (still within 30 days of purchase), will I still receive the promotional benefits? For example, If I purchase the SIM on the last day of the promotion, the SIM card will definitely not arrive at my address before the promotion period end.

      MariamSeptember 16, 2025Finder

      Hi Aaron, yes, the 30-day period should still be valid as long as you’ve purchased it. It’s separate to the promotion’s expiry. Hope this helps :)

      Hi Graham, One Pass uses the Optus 4G+ network. You can see a comprehensive list of MVNOs and the networks they use here. Hope this helps!
