There are different channels of wireless, at least for AT&T VIA A VW TOWER. Should your device get on a slow channel, it will not download file data fast. Talk to VW & have them to check if you are connecting on a slower than LTE channel, even if it says LTE on your device. THIS COULD BE YOUR WHOLE PROBLEM OVER ANY LTE provider WIRELESS SERVICE. When my iPhone DOWNLOADS DATA, slower than 20Mbits/sec, I CALL IN & AT&T MAKES SURE I'm really on an LTE channel, even though VIA a VW TOWER. HOPE THIS HELPS. בובי
