LG G3 Cat 6 can not connect LTE (Only 3G)

I live in Detroit,USA. I am using T-Mobile.My cell phone is Lg G3 Cat6. But I can not connect LTE. ( Only 3G ). Can you help me?

Make sure the APN is set to T-Mobile settings and if that doesn't work then it may not support the American LTE bands and you will be stuck in 3G.

I don't think the F460 supports T-Mobile's penta band set up, it may only work with a couple of them. Check their bands and then look in your service menu by dialing 5457#*460#

[Q] Can AT&T be used with a Korean Optimus G Pro?

Hi everyone and thanks in advance for your time.
I have an unlocked Korean Optimus G Pro from the Olleh company. I switched providers to AT&T but it seems that the phone doesn't has access to the Data network provided. I have great phone signal but no Data network (No 4G LTE, 3G, Edge. Nothing at all). Everytime I turn on my data I get the message "Connection unavailable. Configure Mobile Network or Wi-Fi settings to download data."
I understand that AT&T is GSM. But this phone so far is only working with WCDMA only. I've tried switching it to GSM or any ways to make data network available with AT&T but so far it is not working. I checked the WCDMA Service settings but no luck.
Can anyone help me with this? Thanks! :good:

[Q] [SGH-M919v] Galaxy S4 no LTE

Hello,
I have an open-line Samsung Galaxy S4 (SGH-M919v) and the problem is that I can't use the LTE feature of this device even though there is a sticker of LTE on the phone. The network mode option doesn't show LTE option as it only says WCDMA/GSM, WCDMA Only and GSM Only. I also tried to change the settings in *#2263# but selecting LTE changes the Signal bars to " Ø " I upgraded from Kitkat (4.4.2) to Lollipop(OTA) and still the LTE option on Network mode is missing.
I am using an LTE sim and also am very sure that I am in an LTE spot. The phone was from Canada but I don't know which network specifically it was subscribed to as it was only given to me.
Hoping to fix this problem as soon as possible, Thank you.

You should ask here:
http://forum.xda-developers.com/galaxy-s4-tmobile
But probably there isn't anything you can do. You phone doesn't really support LTE. It support some bands, but your provider is probably using a different band for LTE. So your phone will never get LTE with that provider.

Choose "automatic" after dialing *#2263*
Worked for me.

I had a vzw s4 and was able to get lte in a hybrid att area. I had to use lte specific locked band in the options and would change to gsm or automatic when i left the hybrid area to be able to place calls etc. In the hybrid area everything worked fine.

4G Network Spectrum

Hi
Currently I'm not being able to get the 4G network and in mu country they're using the 1800 frequency (LTE 1800).
Is there a way to change it in the settings so as I can get hold of the 4G?
Thanks.

You should get 4g on the 1800 frequency. You can change between 3g and 4g in mobile data settings. However even if your network has 4g it will display 3g if you are not in a strong 4g signal area. It is the same here in the UK, 4g is fine where I live but I go over a bridge 5 minutes walk away and I can only get 3g! On some networks you need a new sim card for 4g to work as I did. Also do you have the correct APN settings for your network?

Yes I have the correct APN; otherwise if it's wrong I won't even get any data connection. Yes, I might be in a region where it's weak or unavailable but when I'm in a region fully covered by 4G, just outside the HQ of Orange, I still don't get it.

Try using mtk engineering mode app from play store(by go! or themonster) to force LTE - it's under telephony/network selecting.

yes then what do you do?

Note 4 N910A No 3G?

Hello! I got my ATT Note 4 yesterday and 4g LTE works fine but for some reason I can't get 3g to work on it. I tried going to "mobile networks" but i couldn't find the "network mode" so i can't choose which I want so i used the code "*#*#4636#*#*" and tried setting it to "WCDMA Preferred" then "WDCMA Only" and "GSM/CDMA Auto" but i still don't get 3g.
My mobile carrier is Cricket
Thanks for reading!

Y do want to 3G 4G faster

Just a guess, you might not have 3G APN setting in your phone. Try different sim and test 3g on it. If it works then u need settings or new sim. If dont then take your phone to carrier customer center and they will help you.
