my daughter went to China, the phone has international roaming and pay per use international calling too and data too. However, we cannot contact through any phone. My daughter phone has message showed "the phone not registered" (she called me from China to Canada. And, I went to Koodo shop, they can't help too. But my wife has rogers, its works.

You'll have to give us a bit more information. Which phone is using Koodo? Is it your daughter's phone in China that is using Koodo? Can your daughter make calls or send texts to phones in china? Does her data connection work at all? Which Add-on specifically have you tried to apply to your account?
