calling now...
*edit*
well of course they suggested resetting network settings,which I had already done.That had actually solved my slow wifi download speeds, but not the LTE. I just tried it again and got about 5 mbs down. That's terrible. They couldn't find any problems that may be affecting me and I'm not being throttled so they put in a "ticket" and they'll get back to me. Wonder if it's a problem with the phone itself....
Only good thing is that she sees that I have been using less than 1 gb of data per month while on the old "unlimited" plan I've had for a long time,so I'm switching over to a 1gb family share plan for now and saving about $40 - $50 on my bill.
