[Q] Force LTE on Z2? - Xperia Z2 Q&A, Help & Troubleshooting

Hi,
Is there a way to let my Z2 Force using LTE?
I'm in a place where LTE signal is not so strong, so I think the phone preferred H+ than LTE. My friend told me that he was positive that there is LTE signal here.
Thanks advance.

You can choose LTE only but that's not smart thing to do.
If there's no LTE signal you won't have signal at all and battery will discharge faster because your device will struggle to connect to and fine LTE...
LTE/WCDMA is perfectly fine.
If there's LTE signal device will use it.

Hi, off topic... but may I know which theme are you using? Is it just a theme or a custom ROM?

Thanks for the reply, I have yet to root my Z2, will surely check out your theme as well, which by the way looks stunning!

Thanks for supplying that service code in this thread!
For some reason my Xperia was stuck using hspa+ even
though I knew I had a good lte signal here and I saw that
it was set to use wcdma only for some reason.

No longer available in lollipop?
Hi,
After upgrading to lollipop this option is already n/a (not applicable) can anyone please help how I can force LTE only in this phone?

Interesting on the Z2 it says "Network Mode N/A" in grey. On the good old Z with Lollipop its still working. Just used it to force the better LTE for USB tethering.

Xperia C3 Dual
But I can't see any LTE related option (ex - LTE only) when I am dialing *#*#7378423#*#* from my Xperia C3 Dual phone.
Could anyone help me on this please..
Thanks a lot for the help in advance.

[Q] ATT Note on H2O wireless

I am running my note on h2o and have successfully been running on 3g and 4g(hspa+) but I have been searching through google and even asked an h2o cs rep about the note gaining access to att lte service but i have gotten no luck on finding an answer. So i thought i might as well ask here. Do any of you know if ATT will allow mvnos to access their lte network?

[Q] Prefers 3g over 4g

My office is notorious for bad cell phone signal. For some reason in the office my Galaxy s4 seems to connect to 3g, which barely has any signal, until I reboot at which point it connects to the 4g network with one bar, which is still allot better than its 3g signal. My rezound always connected via 4g and it was fast enough to tether my Kindle, nexus 7, and laptop.
Any suggestions to improve signal or make it connect to 4g instead of 3g without rebooting?
a bunch of us friends get together every wednesday night at this chili's near our house and for some reason the second we go inside our 4G drops out. we all have samsung phones, note 2's, S3's and now my S4 and the best way we found to restore our 4G when in the building, toggle airplane mode on and off. we go from having no 4G, to full blown 4G
I agree

Which app is this? I used to use LTE switch on my rezound. I could set it for LTE, CDMA and it would cut out 3g entirely. Most of the time my rezound preferred 4g, but would occasionally revert back to 3G. LTE switch or any other of the Play store LTE toggle apps do not work on the S4.....So what makes this one different?
Edit.... Ok so I installed it.....First THANK YOU. It's just like LTE switch...but it is slightly different. LTE switch had more radio options/combinations. WCdma would make the rezound lock up and go into an endless reboot cycle, so you had to use Cdma auto prl for 3g. But it had the standard LTE, CDMA, EVDO for 4G, 3G, and 1x. LTE only will not allow phone calls. so I used LTE, CDMA. Will the LTE/CDMA auto (prl) on this keep it from going to 3g like I had on the rezound?

Doesn't seem to be in my case. The phone still defaults to 3g. Hopefully a sim card swap fixes it. If not, we're looking at warranty exchanges.

Yeah this sucks. If I hit LTE it will switch to 4g and then I go back to lte/cdma/auto, and will switch back to 3g. If it had the ability to block evdo than it would stay in 4g or 1x only. Maybe this can be tweaked? The rezound had a number sequence you could dial to get into the same menu that lte switch would give you.
New sim fixed the issue for me.

Who developed this app and is it safe? Not that I think you are out to cause harm, but side-loading apps merits these questions and concerns.

It looks like this is just the Phone Info shortcut app.
Phone Info is an android system app (pre loaded), this app is just a shortcut to it (rather than using a long dialer code to get in).
I tried the long dialer code (*#*#4636#*#*) but that did not work. This app did the trick for me. Many thanks for posting it.
This also happens to me....see below. It shows i have 4G, but isn't connecting to it.

[Q] T-mobile USA LTE connection - help needed

I have a D6503 with A.0.167 from taiwan. When I use it on T-mobile network, the preferred network mode is 4G(preferred)/WCDMA/GSM. I never see an option with LTE in it. Also, the signal is very weak. I'm under the impression that the phone never connects on the LTE network.
Does anyone know what I shall do to fix the problem? Thanks!

Are you sure this is a D6503? I use my imported D6503 with T-Mobile and LTE works fine on 23.0.1.A.0.167-

T-Mobile's network doesn't have the strongest coverage, but whenever you have an LTE signal it should connect that way.
My options look like this:
Preferred network mode
-WCDMA only
-GSM only
-WCDMA (preferred)/GSM
-LTE (preferred)/WCDMA/GSM
I'm positive. I got the information by dialing *#*#SERVICE#*#*.
Could you please tell me your customization version number? It can be found by dialing *#*#SERVICE#*#*, and then select SERVICE INFO -> SOFTWARE INFO. Mine is 1281-5456_R1B, which is for phones used in Taiwan. I am wondering whether that matters and whether I should flash a different firmware.

USA its called 4G which is only 3G/3.5G. Which I don't agree with.
While in other countries 3G/3.5G is called H+/3G

Understood now. When the signal was good, I got 24Mbps down and 12Mbps up. So it's good.

What is interesting is that he has a Taiwan ROM and Sony has the LTE / 4G terminology is swapped by geographical area.

It wouldn't be impossible to get 24 Mbps down on T-Mobile's "4G" HSPA+ network, I've gotten 23 Mbps a couple times. 12 Mbps upload would be a bit of a stretch, usually only 2-4 Mbps are seen.
My phone has customization version 1281-1981_R1B. I can't quite remember off the top of my head but I believe this phone was destined for the Indonesian market.

BeameD From My LG V10... The one with the ALWAYS ON SCREEN... Watching me.. ?
Thank you chiikko561, that helped.
I set up the APN. I was only getting Tmobile's Edge network. If I changed the network mode to LTE/CDMA if forces it to LTE but I cannot make calls or txt. I am trying to find an option for my Verizon unlimited data plan. I cannot get anything but satellite for internet where I live. This phone would become our home internet hotspot. I don't really need talk/txt on this phone so I guess LTE would work for me, just want to solve it. Any suggestions appreciated.

Do did changing the apn work for you do make calls and use LTE? Or are you still only able to do one and not the other without changing the network mode?
Did you turn volte off?

VoLTE is not dependent upon band 12. I have TMO and am on band 4 with VoLTE...
It's strange but I think Verizon is behind this issue because I can get LTE using the LTE/GSM/UMTS for about 30 seconds then it just drops from 4G LTE to H. When I turn off Mobile Data then turn it back on it will see T-mobile's 4G then drop again.
Am trying to do switch also my V10 from verizon to tmobile when I put my sim in it automatically switches to tmobile apn and does the same it shows 4g/let then goes to H any suggestions....
You may never get full function of the Verizon phone on T-Mobile.
Reason is Verizon runs on CDMA and T-Mobile runs on GSM.
And I don't think the V10 has the ability to be both.

3G and 4G with AT&T.

I'm in the USA. Got this phone, put my FreedomPop SIM in (a AT&T MVNO).
And pretty much everywhere in my city it stayed at 3G.
I ported my number to Red Pocket (another AT&T MNVO) because I was sick of FreedomPop's messaging app you're forced to use.
With the RP SIM, same thing, mostly 3G.
I know this phone doesn't support AT&T's main LTE band 12/17, but supports 2,4 and 5.
So, playing around with settings (*#*#4636#*#*) I changed Set Preferred Network Type to: LTE/UMTS auto and it changed from 3G 850MHz (Band 5) to 4G Band 2.
Will it fall back to 3G when it needs to with this setting?

OK, I changed my Preferred network type from 4G/3G/2G to 3G/2G and it automatically changed to 3G.
Changed back, and back on 4G.
Think I'll be OK.
Something to check for fellow US users that might have this issue.
I'm also in the U.S.and have freedompop but I get 4G. At least it says 4G in the status (not LTE). I don't know whether I'm actually getting 4G speed. Seems fast enough.
Good to know this trick, in any event
Thanks
