Hello, @dbut6464.
Welcome to Rogers Community Forums! 🙂
I appreciate your posts, were you able to make FTP work on the ZTE connection? Since it works on the home Internet, the issue could be related to blocked ports.
You may want to post more details about your FTP usage like you are trying to transfer files from your computer to a server etc. so experts can advise.
Cheers,
RogersMoin
