The reason why you can't purchase foreign exchange through the account opening network card may be that your account opening branch has no foreign exchange remittance authority, which means that the account opening branch can't handle foreign exchange remittance. You can consult outlets and bank customer service hotlines to see where you can handle foreign exchange remittance.

Extended data:

Buying cash is to change local currency cash into foreign currency cash, and the handling fee is slightly higher than buying foreign exchange, which can be reflected in the daily foreign exchange selling price (the price that banks sell to customers) and the cash selling price issued by China Bank. In China, our functional currency is RMB. When we need to pay foreign currency after a foreign currency transaction, it is called buying foreign exchange and paying in foreign currency. Buying foreign exchange is a transfer transaction, that is, using the local currency in the account to exchange foreign currency, which is equivalent to foreign exchange trading. The converted foreign currency is still in the account or bank card, and no cash has been withdrawn. However, after 20 14, China opened the policy of foreign currency exchange, and individuals and institutions that need to purchase foreign exchange can buy foreign currency through regular foreign currency exchange companies and get cash. Therefore, purchasing foreign exchange is no longer a simple banking business.
