So I got a new sim where the number was transfered from a Telstra number and it all seemed well and good. I opened the My Optus app and was able to successfully activate the sim in the app etc but when I went to click on the "usage" button it just said 'A system error has occured. Please try again at a later time." It did the same thing for the "perks" button. So I searched the internet and found that clearing the cache was a good start so I did that and it didn't work and so i uninstalled the app and reinstalled it again countless times and it hasn't worked. I would really like this fixed as soon as possible so that I know how much data I am using.
Hey @Nader, when was your service activated? It can take a few days for your app to update.
If it has been over 5 days, please feel free to send me a private message with your phone number, full name and DOB. You can leave it with us and we'll have someone check it out asap.
