[Q] How to Keep LTE and HSPA while Disabling 2G/Edge? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

How to keep LTE and HSPA while disabling GSM/2G/Edge?
I keep randomly getting the "No Service" problem with Telus, and I'm assuming it's a very similar problem with the original S1.
I know you can set it to HSPA mode only, but I'm assuming this means no LTE.
I've gone to the phone codes > debug mode, but there's no option for LTE and HSPA... (not unexpected)

Settings>Wireless and Networks, Select "More...">MobileNetwork>NetworkMode>HSPA/LTE. This will ensure you connect to LTE while in LTE capable zones. You can also stay on only HSPA to save battery. Cheers.

Thanks, but that isn't an option.
There is no HSPA/LTE option, only GSM/HSPA/LTE (auto). I want to lock it out from ever getting to GSM (2G).
And no, I do not want to stay in HSPA mode, or I might as well have bought an international galaxy s3

In mobile networks switch network mode to wcdma only.
Edit: could be hspa only, depends on your model.
4g is not lte by the way. If youre on lte it says lte not 4g
Sent from my LT28at using xda premium
lte is 4g on most roms that I have seen. Although I never used the lt28at just the lt28i and lt28h where hsdpa+ is called h+ and lte is called 4g.
There should be a toggle that you can download that will be able to click 2g 3g or 4g. I know on miui there is a toggle for that.
If you're using a Lt28at like me, you can't toggle anything but LTE. SInce the boot loader is locked it will give you the option to pick a different frequency, but will automatically revert back to LTE. Sucks.
The version i have only give me LTE data, or no data at all.
It is locked to rogers.
Can it be changed so i can use 3G only?

No. Your boot loader is most likely locked also. You can only choose LTE. The only other option is to find the APN setting for 3G and enter it in your mobile networks and choose it. It will only use 3G but your phone will always search for LTE by default. You will save some battery by going that route. I don't know what the 3G apn for Rogers would be, however or if there is one. AT&T has a separate apn for LTE and 3G. Maybe someone else here knows more...
Yea, i just found out this can not be unlock... thinking android can be unlock easily since my last 2 phones can do it.
I will find the 3g apn.
Hopefully someone can find a way to unlock it and use other rom..

Think you have to be rooted. Install the app Advanced Signal Status and under "additional info", then "device info" you can choose for different options.

when I am using my galaxy note 3, I input *#2263# to go to a menu where I can force LTE/WCMA my device and mostly it connects to only LTE.
in the Galaxy tab S , the code works but the option for LTE only is missing. so now I continuously connect to a slow 3g network.. bummer...
*UPDATE:
apparently you have to deselect all GSM bands and just select all LTE and WCMA bands.. you wont be able to use GSM bands but your device will lock on to LTE connections if avaialbe, 3g will apply if LTE is unavailable. hope this helps

Phone stays on HSPA when LTE is available

So I own a D851, currently on T-Mobile with good LTE speeds in my area but quite often the phone switches to HSPA and doesn't utilize LTE coverage when I need it. I end up having to either switch data off/on or accessing the radio settings menu and setting it to LTE ONLY. I understand the slower network coverage saves battery but to just stay there I don't get when I'm getting download speeds of 9mb on HSPA and 30mb on LTE in the exact same spot. The thing that sucks about setting the radio to LTE ONLY is that I can't browse while on a call. Anyone know a workaround?

I had the same issue with ATT, unlocked phone. Made sure the APN was correct, tried may other APN settings, and finally called Consumer Cellular. They advised I did, indeed, have the correct APN (my first version). They did some type of reset on their end, and viola.
On my OnePlus it was the similar. APN was correct, same APN as the G3, but until I called CC, and their reset, phone would not show LTE at all, only H and H+
apn settings?

What are the apn settings that are working for you? I've tried several times to address this issue with CC but lte STILL isnt working on either of our 2 devices. Had no problems when used with an att account.
I am still having this same problem on my LG G3 (vs985) on Cricket Wireless

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?

How To Force 3G?

I've tried *#*#4636#*#* but the code doesn't work. As soon as I type that, my phone dialer just goes blank. So how do I force 3G?
Do you mean basically shut off LTE (force only use of 3G and GSM/2G/EDGE)? Since GSM is the often used fall-back from 3G, and it's not currently a great idea to only have 3G. At least not until carrier start shutting down the GSM networks (which is coming soon, from what I understand).
If that is what you mean, if you go into Settings>Mobile data, do you have the Preferred network type, with the option to force GSM and 3G? Or does it just change back, if you do have this option shown?
What carrier version of the M8 do you have? The network type is locked out (to always allow all three: GSM, 3G and LTE) on the US carrier versions. And this also affects the dialer codes to force the network mode.

Nah, nothing to do with 4G but my network keeps switching back and forth (3G/2G). I've noticed that this causes some battery drain
The code has worked previously with other ROMs but not quite so on Verizon 6.0. I wouldn't mind locking to 2G either since I don't use data
