Because there is an alternate method to bypass using 2FA, it doesn't truly provide any additional security to a Ting account, it's simply an additional hassle and poor customer service experience.
If there was no alternate method, then losing your phone (and along with it, your SMS and authenticator app) would mean you couldn't login to Ting to replace your phone and SIM. So that's not a good option either.
So, please provide an option to permanently disable 2FA on my account, rather than giving a spammy pop-up every time I login to my account in an attempt to force me to enable it.
I just spent 40 minutes in chat with support until they finally told me there is no current way to disable 2FA.
