What if I can't get on the phone after changing my mobile phone?

If the APP can't log in after changing the mobile phone, you can try the following solutions: confirm the network status, check the account information, complete double authentication, appeal the account, retrieve the account through binding information, and contact customer service.

1. Confirm the network status: Check whether the network of the new mobile phone is stable and ensure that you can connect to the Internet, because network problems may lead to login failure.

2. Check account information: carefully check whether the entered mobile phone number and password are correct, so as to avoid being unable to log in due to incorrect input.

3. Complete double authentication: If the account is enabled with double authentication, you need to complete the identity authentication on the new phone according to the prompts, such as entering the verification code.

4. Account Appeal: If the old mobile phone number is no longer used or the verification code cannot be received, you can get your account back through account appeal, and you need relevant identification and account information.

5. Retrieve the account through the binding information: If the account is bound with Alipay or auxiliary email, you can try to retrieve the account through these binding information and choose the corresponding verification method.

6. Contact customer service: If the above methods fail to solve the problem, you can contact the nail customer service staff for professional help and guidance.
