199 cannot handle mobile unionpay.

199 belongs to VoIP, and the bank does not recognize it.

199, as a new number segment released by communication operators, is not compatible with some bank software platforms, so users can't recognize it when setting 199 as the default contact information when handling business in some banks.

It is mainly caused by the slow updating of the number base of some enterprises, which has nothing to do with China Telecom itself.
