I am on an extended journey through Europe and reverted to an Optus prepaid SIM before I left to be able to retain my number and access 2 factor authentication while I am travelling.
The SIM I bought does not connect to the network in Spain, I have spent hours and hours trying to get this resolved with the support team with no outcome!
I have allowed roaming, I have allowed data I am opened up every possible setting to achieve connection to the network but still remain unconnected.
I am stranded and running out of funds (requiring two factor authentication for EFTs)
What device are you using?
Do you have any "real money" credit?
What Prepaid plan are you on?
