Postal savings: Hello, the free trial period of the current account change notification service for your account with the suffix XXX will expire in 5 days. To cancel, please go to the local area.

Hello, the notice of account change of Postal Savings Bank is a short message notice. Normal SMS notification requires a monthly fee in 3 yuan or an annual fee in 30 yuan. When your account balance changes, I will send a text message to your mobile phone. Maybe your SMS notification service has a probation period, and you will be charged after the probation period, so the postal service sent you such a reminder message.
