Consumers can log on to the relevant bank in official website to inquire about the specific charging standards, which may be adjusted by each branch. The specific price is subject to the final announcement of the outlets. The SMS service fee will be charged from the signing day. If consumers enjoy the free probation period, they will start charging on the day after the end of the free probation period, and then charge monthly (including the billing cycle) or monthly. Each billing cycle is from the start date of the current cycle to the day before the start date of the next cycle. If consumers need to cancel the SMS service fee, they can customize the message service pages of mobile banking and online banking, close them by themselves according to the page prompts, or cancel the SMS reminder service at the relevant banking outlets. Some banks (such as China Construction Bank) provide free SMS reminders for all credit card withdrawals, foreign currency transactions and large RMB transactions in 500 yuan and above.
