According to your description, the attribution of calling number has nothing to do with the mobile phone card. Depending on whether your mobile phone supports it, at least one of the following conditions must be met:
1, the mobile phone itself has this function.
2. If it is a smart phone, you can install third-party software, such as incoming calls, Xin Anyi, etc., and you can also display the attribution of incoming calls.
