I used to have some $0 data share SIMs on my business account. These were upgraded to $5 Business Data Share SIMs when the $0 ones were discontinued in May 2019. These have been working fine up until 11 Feb 2020. I pay for these every month of course. One SIM has now stopped working and I have been advised that the $5 Business Data Share SIMs were discontinued in May 2019 (when I signed up for them!). Is this service plan still available for existing customers? I know it's not available for new services. I've had no notification of any change.
