If you get a Twitter account locked out and it needs to phone verify but the phone verification number was a throwaway from an online service, is there a way to have it send to another number or is the account lost?
Unfortunately, no way to get it back.
Maybe contacting Twitter support via email but don’t keep your hopes high.
damn that stinks… so is it best practice to always remove the phone number after verifying?
Yes, that way Twitter won’t force you to phone verify via that number
Only thing you can hope for now is recovering by an appeal to Twitter.
However like it was already specified, unfortunately there are slim chances for success…
Do your try anyways.
what is the best way to contact twitter about an issue like this?
