What will happen if the information center is transformed?

You will not be able to send text messages. The short message is sent to the information center by mobile phone first, and then sent to the person you want by the information center. Where did you get the card? You should use the information center number. There is no roaming fee for sending text messages, which means that you are a card from Hebei. You still need to use the number of Hebei Information Center to send text messages in Beijing, so you don't need to change it. The charge for sending text messages is the same as that in Hebei. This number can't be changed either, which will cause the text message not to be sent out. There is a rule for the number of the information center, which is +86 1380****500. The four asterisks in the middle represent the area code of your card office. For example, if I am in Changsha, the area code of Changsha is 073 1, and the card information center in Changsha is +86 1380073 1500. According to this rule, if you accidentally change it to Beijing, just change it back according to this rule.
