Seriously? Which ones don't support it, I actually have found more that are "esim only" these days (but I am someone who churns through ozbargain deals)
- lack of eSIM support
- invoice/statement layout hard to read
- businesses can use the residential NBN plans but they don't display correctly on their Carbon business portal
- some advanced mobile service control codes to configure message bank, call forwarding, etc, don't seem to work
Everything else about them has been perfect. Great service, reasonable prices, perfect reliability (zero downtime AFAIK!), and Australian-owned.
