The real-time exchange rate refers to the real-time exchange rate, which changes at any time according to the fluctuation of the foreign exchange market. Settlement of foreign exchange on mobile phones may not be the real-time exchange rate, because banks or payment institutions update the exchange rate regularly or at intervals, not in real time. This is done to avoid exchange rate fluctuations in the process of settlement, which will lead to changes in the amount of foreign exchange to be settled by users. Therefore, when settling foreign exchange on mobile phones, the exchange rate presented may be based on the latest exchange rate, not the real-time exchange rate.

In addition, the foreign exchange market changes very frequently, and the real-time exchange rate may change quickly. Therefore, in order to accurately settle foreign exchange, it is suggested to reconfirm the latest exchange rate information before the actual settlement operation. This can get the latest real-time exchange rate by contacting banks or payment institutions or using professional real-time foreign exchange quotation software.

In short, the exchange rate may not be updated in real time when the foreign exchange is settled on the mobile phone, so the latest exchange rate information can be reconfirmed before the operation to ensure the accuracy of the transaction.
