How to suspend the service of telecom mobile phone short message?

According to your description, Tianyi mobile phone can't handle the shutdown (stop the phone number) business during the agreement period, otherwise it will default and there will be no short message for the shutdown business. After the agreement expires, you can settle the phone bill at the front desk of the local telecom business hall with your ID card, and the longest time to stop the number is 6 months. I suggest you continue to renew the fee. If you don't have time to pay in the telecom business hall, you can log in to China (Anhui) Telecom Online Business Hall (/) to pay by yourself, and now you can enjoy the discount of 50% off the phone bill to 2 yuan.
