Does etc. deduction only apply to text messages bound to the ETC mobile phone?

Generally yes.

After applying for etc., the system will automatically record the tolls related to the car. The tolls will be deducted one to three days after the car passes. Afterwards, a text message will be sent to notify the car owner of the high-speed tolls spent on the trip, but some The bank has set up a policy that does not require SMS notifications for small purchases below 500 yuan.

The Etc system uses microwave communication between the vehicle electronic tag installed on the car windshield and the antenna on the Etc lane of each toll station, and automatically deducts fees through Internet calculations. To successfully debit the Etc system, make sure that the card bound to the Etc electronic tag has sufficient balance. If the balance is insufficient, it will not affect the personal credit report. The car owner can call the customer service center of the credit card to inquire. Generally, Etc debits are recorded first. The method of unified deduction at the end of the month and the settlement day can save the work of the driver and the system.
