Galaxy S4 Model SGH-M919
Hello
Our company is a new T-Mobile Business customer of one month.
We found all services great including the Mobile Hotspot (Thank you!) except for a problem which we recently encountered.
We have a retail website, shipping orders to all 50 states and 18 countries.
We need the ability to modify, upload/download html files from our retail website when not in the office.
This involves downloading files from our server webserver via ftp (file transfer protocal), editing them on our phones and uploading them again to the server.
We have html file editing and ftp programs on our Galaxy S4 Phones which are able to do this.
However we found that we are able to upload/download files from our website server to our phones ONLY when connected to WiFi.
(we have verified this using our office WiFi AND Public WiFi systems such as in SAMs wholesale club)
When we attempt to connect to our website servers using the T-Mobile 4G and 4G LTE data network, the phone ftp program goes as fas as "AUTH TLS OK." then just "freezes" until it times out.(we tried this with several different ftp programs with the same results)
Before we switched to T-Mobile, we were with Sprint and had No Problems using the ftp programs over their network.
Any ideas ?
(contacted support by phone and could not provide a solution)
Thanks
Chuck
