I did this for my phone bill. I never use my cc for anything and was just using it for the bill in hopes it would help my credit. Well the dang card expired without me knowing, I didn’t get a new card in the mail for some reason. I apparently wasn’t checking my phone bill so I didn’t see it wasn’t getting paid. 3 months went by before the phone company got in contact with me. Just if you do it make sure your cards don’t expire ♀️ I no longer use it to pay bills and I haven’t reactivated the cc.
