Anyways, BAND 4 was already set to ON by default on the service mode so on the next step which was inputting all the right APN to fast.t-mobile.com and all the correct apn settings. Also its set to "Global" and having set to LTE/CDMA doesn't make a difference at all. I get HSPA if I leave it at GSM/USMC.
Ok so now having it set to Global or LTE. I keep dropping signals or losing it 100% completely. I am getting the 4G LTE symbol on my phone with full bar,but no connection??? I live in Glendale,AZ and we have full 100% LTE SUPPORT in our area, my previous LG G2 always had 4G LTE and no issues with connectivity.
AM I DOING SOMETHING WRONG? DO I REALLY NEED TO BE ROOTED? PLUS MY MMSC MEDIA MESSAGING IS NOT WORKING EVEN WITH THE CORRECT APN SETTINGS.
