Yes, that is the plan we had with Aldi, it worked well as long as you topped it up. I need to ring a landline in Australia, so hopefully this NZ sim will work. I did get another one from the Post Office to use in Europe but it was hit and miss. If I still had the Aldi mobile, I think I would just use that as if you don’t use all the top up, it doesn’t expire quickly like the Sims Direct sim.
