OK... First things first; Alcatel Fierce XL, MetroPCS (of course), & Unlimited plan ($60 mo.). So... (this is while at my house): up until about 4 days ago my phone and service were working just great. I had strong signal (full bars) and very fast data speed (4G LTE @ 20-30 mbps). Then all of a sudden, I've got no data flow at all. I've still got full bars, fine voice quality, but NO data. So I do the the data switching on/off thing (both by using airplane mode and by using settings data on/off switch). When I turn the data back on data works fine for about a minute and/or as long as the data flow is continuous as in when watching a YouTube video. But when the data is not flowing for a minute or so and when something requiring data is turned on, the data is now not working. After several frustrating calls to Metro C/S involving resets and manually entering T-Mobile address settings, I tried something different on my own. I turned the LTE off. All of a sudden, I've got data!! It's 3G data (9-12 mpbs) but it works!! Now here's where it gets REALLY weird. The next day I left my house (I'm disabled and don't go out every day) and just for giggles, I turn the LTE back on and it works just fine! I use it all day while away from my home and no problems! When I get back home, the problem returns. So back to the "LTE off" setting and once again while on 3G, my data flows fine. I then downloaded the "Open Signal" app. and write down the cell tower (T-Mobile tower) ID number and info.. The next day I again leave the house and when I get out of range of this "home tower", I can once again turn the LTE back on and everything is fine. I attempted to tell this fellow at Metro C/S all of this info. but he totally "glazed-over" and told me he would advance my problem ticket to a higher level tech.. So.... while I wait for the next move from C/S, has ANYBODY ever heard of this scenario before. Is it a T-Mobile tower issue? Is it my phone? Any INTELLIGENT idea/info. would be appreciated!
