This may help others. I signed up for this offer simply for the 60,000 points. I don't need the mobile plan or the data as I've got heaps of data on my existing plan, and I did not want to in any way affect my current plan or my existing phone number. I already obviously have a mobile phone plan with a physical sim in my Samsung Galaxy S22. You don't have to do anything with your current plan or mobile number. or the physical sim that's in your phone now, and signing up for this offer won't affect it at all. As long as your phone is "dual sim". What you do is sign up for the offer and then you will be able to obtain what is called an "esim" (it just electronic and not another physical sim card. It just downloads to your phone). Phones such as the Galaxy S22 and other latest phones are "dual sim" so you will then have two sims running in your phone. You still keep your existing phone number and don't have to even worry about the second sim (the electronic one) if you're like me and have plenty of data anyway. If you could use the extra data, then you can use the esim for the data allowance. But main thing is, you don't have to affect your phone at all to take advantage of this offer. It's a little confusing to set up but it's not too hard. Then once set up, in my settings under "Connections" there is a sub heading "Sim Card Manager" and after you've got the esim in your phone, you can see that everything is still running on your physical sim, but the "esim" is in there if you want to use it for the data. You will then see in the top of your phone screen where it normally says your carrier's name, that your phone is now running on two services (in my case "Vaya" and then also now "Optus). But my original service is the one I'm actually using. There are instructions that sort of make sense when they send it to you via email.
