How can I log in if I lose my mobile phone number?

1. Check the network status of the mobile phone. Check whether the signal on the mobile phone is normal and stable. If the signal received by the mobile phone is weak, please take the mobile phone to a place with good signal and get the SMS verification code again. At the same time, avoid frequently obtaining SMS verification code. Check the entered mobile phone number.

2. Use email to retrieve your account: If you used email when registering the paper plane, you can try to click the "Forgot Account" option on the paper plane login page and fill in your email to retrieve your account.

3. After installation and opening, the default language is English. Enter +86 at the beginning of the input box, then enter your number in the text box below. Click the blue arrow icon again. Fill in the verification code after receiving it, and the registration is successful.

4. Sending instructions to the mobile phone by searching the mobile phone function failed, which may be that the mobile phone is currently in a network-free state (including no SIM card inserted, power off, and blocked mobile phone network).
