Device: HTC One m7 (verizon, but works on any GSM/CDMA)
Using Straight Talk ATT.
I've been doing some research for the last couple of days. Some say LTE is not supported anymore, others say it is, but you have to force LTE.
I'm trying to figure out a way to get my phone to stay at 4g/ LTE speeds without defaulting to 2g/EDGE.
I've tried using *#*#4636#*#* and selecting "TD-SCDMA,GSM and LTE", but this later defaults to GSM/Auto.
Also status bar displays EDGE, and in settings/ device info it shows Mobile Network Type: EDGE.
This is getting frustrating because I was using T-Mobile straight talk and had the same issue. All I'm trying to do is get LTE working.
So what I am asking is: Is there a way to force my Straight Talk ATT phone to use LTE?
I live in the city, and know for sure that LTE works everywhere here.
