Preparing a returning account
Opening IU7 Game on another phone is easier when the original login details are available. This guide focuses on returning access, including the number used for registration, recovery options and the information to keep ready if a sign-in attempt fails.
Separate an account error from an app error
Notice exactly when the sign-in fails. A message after submitting credentials calls for different checks from an app that closes before displaying its login screen. Review saved entries for an outdated number or password, and use the recovery route shown by the service when you no longer control the original identifier. Reinstalling alone cannot restore access to that identifier.
IU7 Game checklist
Confirm whether the sign-in screen expects a mobile number, username or another identifier. Repeatedly entering the wrong type of identifier will not repair an account problem.
Should I register again if IU7 Game will not sign in?
Do not assume a second registration will recover the first account. Check the service recovery instructions before creating another profile, especially if you need access to existing records. The separate update guide covers replacing the installed build.
