I would like to purchase extra data for a friend of mine who is isolated and without a job due to Covid-19. How can I go about doing this so that we can make contact on apps such as zoom that chew through data?
Depends on your budget really. The best way to make it simple and one off is to go a prepaid SIM. Optus has a great offer at the moment of 120Gb for $150. You can buy it with a new number attached and give it to them. They just put it in their phone and they've got 120Gb.
