Does it cost money to check the phone bill with a mobile phone?

Roaming status seems to be charged according to your usual call. For example, when I was in Fuzhou, I called 10086 directly when I went to Beijing last time. It seems that there is a charge, but the area code can also be added in different places. For example, my Fuzhou is 059 1 10086. He just received 10086 from Fuzhou, and there was a dime in the text message.
