Yes, based on my experience today, one must load airtime before it will work.
The question is how much is enough - is literally R5 enough, or is it based on the Flexi package you loaded previously ?
(they don't state that in the PDF, far as I could see).
(I'd also tried extending the 60 days without loading airtime & it failed).
Try the router, but not sure if it works.
You can add the details of a 2nd SIM in the app, and then use the app to transfer up to 1GB data per month between your main SIM & the 2nd one (in a phone, for eg.).
