When you subscribe/subscribe for the fund through the "Fund Business-Fund Subscription" column of our mobile banking, the transaction is submitted successfully, and the fund trading account and the TA account of the fund company are jointly opened. You can also click on the "Fund Business-My Fund" column of mobile banking, and the system will guide you to open a fund trading account. Tips: At present, mobile banking does not directly open the column or menu of "fund trading account". You can't open a TA account of a fund company separately.
