Hello community peeps! I was recently (Dec 28, 2015) added as a 4th line to my family's T-mobile plan. We have 6GB of fast speed internet as part of our unlimited data plan. Everyone in that plan besides me has a fast connection using their data network. My T-mobile version of LG G3 is upgraded to Lollipop 5.0.1, and although I have a 4G symbol with arrows in the upper right corner, my internet works either very slow or sometimes does not connect at all.
My mobile network is connected to HSPA, sometimes switching to HSPAP. I cannot connect to the T-mobile (LTE) when I search for networks. I can only "automatically select preferred network." My access point names is valid with fast.t-mobile.com APN configuration.
Sometimes I can connect through my data usage (very very slow), but more often my connection is hung up, and I get a message with the following:
"the server closed the connection without sending any data"
A suggestion is made to "make sure you have data connection" while my 4G symbol with arrows is displayed.in its corner. I don't seem to have any issues making calls or receiving texts, but the internet is the only problem I'm dealing with. My wifi works perfectly and never drops. I've done a full factory reset and a hard reset, but the problem persists. Sometimes even, if you will believe me, my network drops me down to the 2G Edge network. I was incredulous, too!
I have contacted T-mobile technical support, and two times the representatives have recommended me to turn off my phone while they reset my network settings or something to that effect. The issue does not lie with the sim because I swapped the sims between my mom's iphone 6 and my LG G3, and on her phone my sim works flawlessly with amazing internet speed while the internet of her sim in my phone is as fast as *imagine* a baby tortoise wading through thick honey.
This leaves me with the very confident hypothesis that the issue has something to do with my phone and possibly the lollipop upgrade, which has stirred lots of trouble for other users.
Any advice for your fellow LG G3 lollipop upgraded peep? Thank you for any help
