I have the free 1000 international LD minutes and I usually dial from Canada to mainland China and HK. The thing is my calls to China recently never went through.
I can confirm the area code and format are correct. Besides, I also tried to dial HK and Australian numbers but these appear to be working functionally.
I wonder has this happened to anyone else? Can someone please resolve it for me? Due to my work I have to make international calls from time to time.
