I cannot make international call while roaming
I have to make a call to Singapore. I am outside of Singapore currently, with my Starhub sim on roaming, but it is telling me that my outgoing calls are barred. I have tried turning it off but it doesn't work. I have also tried *116* number # but that's also not working since it says call divert is active, when call divert is not active.
Need help asap.
