Tenpay can't receive SMS after downtime.

Hello, if your mobile phone number has been changed, but it has not been changed before, you can only change your mobile phone number again through a complaint. When you enter Tenpay, you can verify the key input on your mobile phone, and then there will be an operation to remind you that your mobile phone has changed to appeal, and then press the prompt to appeal. This process may take three working days. Then pat the complaint and email it to you, and then you can reset your new mobile phone number according to the email prompt. I hope my answer can help you. If you have any questions, please feel free to ask me. If you are satisfied, please choose "adopt" on my answer. Thanks ~! good luck
