Stuck SMS problem - Try this out...

Didn't have time to browse all the posts on this issue but while we're waiting for the next useless hotfix from HTC, I tried to go with manual settings for the network and network type by doing the following:
1. Wireless controls>Phone>Band: Change network type from Auto to WCDMA. Left Band Frequency on auto. Done.
2. Settings>All Settings>Personal>Phone>Network: Changed "Network selection" to "Manual". Your device will search for all available networks. Pick your carrier/network from the list.
3. On the same screen as 2, tap on "Set Networks" and uncheck all other networks except your own primary network.
With the above change the phone will only have my home carrier to choose from (not sure if that makes any difference) and the network type will always stay with HSPA which is no problem for me in the area I live, in fact I want that.
Cant confirm if this does it since the issue occurs sporadic, but so far five days without any SMS stuck in the outbox which is unusual for me, used to get it every single day.
Obviously the above leaves it to you to manually manage the network settings as well as running H all the time may be a problem for some, but if this works as an interim (hopefully not permanent!) solution for some users it could be worth giving it a shot...
Cheers.

On mine under Wireless Settings>Phone is only has the options for sounds available?

Jammie: Doesn't sound like the right place. It's basically just the Comm Manager.

Thats right: Comm Manager/Phone then scroll down to Band to make those changes, then Done or Cancel and hit the Menu/Network or Advanced Network tab.
Bear in mind that if you select WCDMA only as opposed to Auto, then you will have no signal at all if you go to a non-3G area (of which there are still many thousands of square miles in UK!); overall its best to keep this at Auto for everyday use.

OK, I did steps 2 & 3 but on the first I had problem... Phone couldn't connect with the network with WCDMA, only with gsm, so I turned it from auto to gsm... I don't care about 3G

have tried all that and it didn't solve the sms problem for me...

[GUIDE][No Root][5.0][4.X] Enabling LTE Without Root

EDIT: Clearly now that there are custom ROMs, this will be less likely an issue. But @icheyne pointed out a good method that will work on most ROMs I believe, since it uses Android's default testing menu.
For those seeking a permanent solution, you WILL need root.
Currently no permanent solution on LG Stock Lollipop.
Here is some information about my situation:
-Currently on Fido Network in Canada (LTE Band 7 [2600 MHz])
-I have achieved LTE speeds of 31mbps (Down) and 25mbps (Up).
-I am rooted, but it should work without root access.
-Firmware is stock V10h-TWN-XX
-Network mode only shows GSM / WCDMA
Before you begin, this is what you need:
-An LTE micro sim.
-Do some research on which LTE bands your network uses and if your variant has the ability to use that band.
-Correct LTE APN settings for your mobile carrier. Make sure it is LTE APN, my carrier has two separate ones (Regular, LTE).
-Mobile Network does NOT have to be turned off (You can keep data on during all of this).
-With Mobile Network on, go into Settings -> About Phone -> Network and remember what is written under "Mobile network type".
-Make sure you are in a location that has decent LTE connection.
METHOD FOR LG STOCK LOLLIPOP
1) Open up your Dialer, and type in the following to enter LG's Hidden Menu: "3845*#855#" for D855 (If your model is not listed, please do Google it!)
"3845*#850#" for D850
"3845*#851#" for D851
"3845*#852#" for D852
2) Go down and select "LTE-Only" and go into "Modem Settings"
3) Now select "RAT Selection" and click on "GSM/WCDMA/LTE auto"
4) Without rebooting, the data icon switched from "H" / "3G" to "4G" for the first time (Turn on Mobile Network if you haven't already)
5) Now go into Settings -> About Phone -> Network and under "Mobile network type" it should have "LTE" instead of what you had before
Currently no permanent solution, each time you reboot, switch to 2G/3G, or go into "Mobile Networks" menu, you will lose LTE
But it's okay, redoing steps 1 to 3 will get LTE back once again. Tedious, but at least it works
--------------------------------------------------------------------------​
QUICK METHOD (Working for all Jelly Bean ROMs & some Lollipop ROMs) (Thanks to @icheyne)
1) Go into Dialer -> Dial *#*#4636#*#* -> Phone Information
2) Scroll down to "Set preferred network type:" and click on the pull-down menu
3) Select what type of setting you want, I personally keep it on "LTE/GSM/WCDMA"
4) Select "LTE-Only" and go into "Modem Settings"
5) Without rebooting, the data icon switched from "H" / "3G" to "4G" for the first time (Turn on Mobile Network if you haven't already)
6) Now go into Settings -> About Phone -> Network and under "Mobile network type" it should have "LTE" instead of what you had before
7) [ROOT][Permanent LTE] For myself, I used a root explorer (ES File Explorer) and go into "/system/app" and delete (or move) LteConfigs.apk and LteConfigs.odex. Now you should be able to go into the "Mobile network" menu and it should have the "GSM/WCDMA/LTE auto" setting. Thus making LTE a permanent option.
Those without root access will lose LTE if they restart, switch to 2G/3G, or try to go into the "Mobile network" menu.
If you have any questions, please leave a reply. Hope this helped.
If anyone who cannot get this to work, please post with your details (firmware, carrier, LTE band, etc...).

i have heard some reports that updating some settings in the hidden menu will work, but after restart, it will just go back...hmmm.. this one retains the LTE option?

Yes, after having it on for a few days, restarts, as well as going to an area of weak reception will not affect it. It will sometimes jump back to 3g in weak signal spots (underground), but after I go outside, it will switch to LTE automatically. I should probably update the title since I've learned that this applies to other models as well.
EDIT: @chacho_2me So I found out what breaks the LTE, but it's not major unless you manually switch from LTE to 2g or something like that. Step 11 should say it all, just don't go into the mobile network menu, and you should be fine.

thanks dude..currently im roaming....will try this one when im at home
thank you so much sir.. hope i could help you sometime
I really dont know why LG didnt notice not having the LTE option on othe releases
anyhow...thanks again dude

@chacho_2me Very sorry, I don't know what happened, but unfortunately restarts reverts it back to 2G/3G. But I'll look around to see what I can do to get it to retain, will most likely need root.

If it already states LTE under Settings > About Phone > Network, would you still recommend going ahead with this tweak?

@Curleyyy Are you getting LTE reception though? If you are, then you don't need to do this. This isn't really that much of a tweak, more like just some hidden settings, that's all.

If I'm not mistaken > 2G > 3G >4G > 4G LTE ?? Reception around my place is usually 3G with a bit of 4G occasionally.

@Curleyyy In terms of speed, LTE is currently the fastest. But reception wise, it might not be the best choice. If you are in an area with poor 4G/LTE reception, it is best to go with 3G connection. If you like to find out exactly which regions have 4G/LTE, I'm sure your carrier will have that information on their website.

Thank you so much
It's working fine on Fido. A heartfelt Thank you
Cheers

I found a solution that doesn't require knowledge of the network's LTE bands:
Dial *#*#4636#*#*
Click Phone Information
Scroll down the page to the GSM/WCDMA dropdown.
Select LTE/GSM/WCDMA - the data icon should switch from H or 3G to 4G.
[ROOT ONLY] Using a root file manager (ES File Explorer) go into "/system/app" and rename LteConfigs.apk and LteConfigs.odex to LteConfigs.apk.bak and LteConfigs.odex.bak
Reboot
Go to Settings -> Tethering & networks -> Mobile Networks → Network Mode and select GSM/WCDMA/LTE auto.

@icheyne I confirm that works, I will change the post.

I need to change lte band. What way i have. Secret menu ont allowed me to do it in Android 5

Oh dear, that's inconvenient. I don't have lollipop installed yet, since it's been quite busy for me and I need my phone. I will try to update the guide for Lollipop.
When I can test it personally, but for now, if you could try to surf the forums. I am short on time lately, I do apologize.

On mine, only the .apk file was present, not the .odex file. I have flashed a stock-based lollipop rom. I renamed the .apk file and the lte was added to the mobile networks menu, but my phone is still not connecting to lte .
It is correct, the "phone information" menu loads on lollipop, but an error message pops up overtop and you can't get to the settings due to this.
I sure hope I can get this working or I'm going to have to get a different device!

@vinistois Thank you for reminding me about this. I do apologize in advance for not keeping up with this as I am still sticking with JB for the time being. I just flashed L to try to clear things up. Are you currently rooted? And do you have the D855 model?

[Q] Stuck on "EDGE". How can I change the Network under "SIM Status" ?

[Q] Stuck on "EDGE". How can I change the Network under "SIM Status" ?
I'm running Dirty Unicorns 9.8 OFFICIAL (5.1.1) on my Nexus 4. The other day I noticed I had like one or two bars so went into Settings > About phone > Status > SIM Status and clicked "Network". Usually, there are a handful of providers to use there and sometimes changing to a different one improves my reception (This is a T-Mobile phone). I don't remember what I left it on.
Today the phone is stuck on "EDGE" under "Cellular Network Type". I tried to get back in the "Network" to check and see if I left it on something stupid, but I can't get back into the provider selection. No matter what I do, the device won't hook up to "LTE" (whatever HSPA/HSPA+ thing T-mo says is LTE). Everything worked fine last week. Haven't applied any patches or anything other than messing around with the Network settings. Any idea what I might try? Is there a magic dialpad entry to use to reset the Network?
Thanks

Same problem here with metro pcs who uses T-mobile

After a few days of this, and several chats and calls to T-Mobile, it seems T-Mobile is "working on towers" in my area and things will be like this for a few days. The situation is this according to the last phone call with T-mobile:
* HSPA+ is no longer available on the towers in my area
* LTE and GSM (Edge) are the only supported modes
* LTE is not supported on the Nexus 4. tuff-shizz. buy a new phone.
Ok well this sucks... so here's what I did in the past couple days.
* Installed Chroma ROM and the the LTEEnable zip file thing floating around all the forums here.
* Found out Chroma was a rebranded AOSP ripoff so uninstalled it.
* flashed Dirty Unicorns 6.0.1 to my Nexus 4, bluetooth seemed funky so flashed the .33 radio from "dmitry" ROM that I found on several threads. Also flashed LTEEnable zip, not sure I needed it. LTE now working.
* dialed *#*#4636#*#* and went into "Phone Info"
* Network Type: "LTE"
* Set Preferred Network Type: LTE/GSM (PRL) -- originally had this set to "LTE only" but no voice calls could go out, or come in.
You would think this is the end of story, but wait. Voice calling takes 20 seconds to connect (even voice mail). With "LTE only" settings all incoming calls go directly to voice mail. never even rings the phone. Are you shizzing me?? With "LTE/GSM (PRL)" the phone waits for 20 seconds to drop from LTE back to "Edge" before the call finally hooks up.
Today, found out nexus 4 doesn't do VOLTE (Voice Over LTE). at least thats what google said. That would explain the Drop to "Edge" when dialing out.
Thing is, I tried this with a NEXUS 5 on my account, using two different sims , running stock Android Whatever on the N5 and it does the EXACT SAME THING. dropping calls to "Edge" before connecting. Takes 20 seconds to dial out. Incoming calls on LTE (which the n5 runs by default) all go to voicemail.
So it seems the workaround now is to dial the "magic number" above and set the "Preferred Network" to "GSM only" (Edge). That's the only way to get phone calls in or out of either device on T-Mobile's network today. Don't bother trying to Google anything though because it won't re-connect to LTE to do it. On either my hacked N4 or the stock ROM N5. You may as well be using a dial-up modem to get any data through either phone.
So, in the end, I don't have anything screwed up under "Network Settings". I'm stuck in "Edge" mode because Tmo is updating towers for LTE. It remains to be seen if I have to upgrade both and N4 and N5 to stay on T-Mobile however. The next few days will tell. I still think this is a bit of a ****-move on T-Mobile's part. Especially if I have to upgrade the N5. It's an expense I wasn't planning on. They could at least kick in some rebate to help out with the cost of new devices. No idea if it would save any money to switch carriers at this point.

How to force 'LTE only' on LG V20

This is a guide for those who want to force 'LTE only' on LG V20 Global dual sim version.
As anyone knows, *#*#4636#*#* WILL NOT work with LG V20 and all LG phones starting with Lollipop and later Android versions except for the LG-Nexus releases. LG has locked this menu. Samsung and Huawei are also notorious for locking this menu. These phones will show 'access denied' when you try to force 'LTE only' using the *#*#4636#*#* service menu.
There are however phone manufacturers who do not lock this menu. These include Sony, Asus, Oppo, Vivo, Xiaomi, Google Pixel, and Nexus phones (various manufacturers). I don't know why manufacturers lock this menu when it is very helpful to users in areas with weak but consistently available LTE signal. By being able to force 'LTE only', you get dramatically better speeds as compared to 3G only.
Anyway, the good news for LG V20 H990 (dual sim version) users is there's a way to force 'LTE only' despite LG locking out the *#*#4636#*#* service menu:
I've outlined here the steps for the workaround:
Note: For LG V20 (H990 dual sim model) only
How to set ‘LTE only’ data mode for SIM1 slot on
LG V20 H990 dual sim version:
Important:
1. When on ‘LTE only’ – you cannot receive calls but you can receive texts. If you go out of an LTE area, your SIM1 (on ‘LTE only’) will be off or will not have any network signal; it will not do automatic switching to 3G or 2G under ‘LTE only’ so you lose the ability to send/receive text messages as there is no LTE signal.
2. This setting only applies to SIM1 slot of the dual SIM model of LG V20 H990. This will not work on SIM2 slot so be sure to place your ‘data-only’ sim to SIM1 tray while placing your ‘call and text’ sim to SIM2 tray (so it won’t be affected by the ‘LTE only’ setting).
Here’s the code to input on your dialer:
*#546368#*990#
Field Test
Modem Settings
RAT Selection
Choose LTE only
If you want to revert back to auto network settings, you can follow the same procedure but choose 'GSM/WCDMA/LTE auto' or other settings instead.

It works, but sometimes it makes the signal to no signal.

Great
I trie many things to changing roms...None of them worked. I'm very thankfull to this simple solution. I chose LTE/GSM and now network problems completetely finished.

APK
The app LTESwitch will work. I uncheck all options in the program, and just use the dropdown setting from the status bar to select (L)TE or (A)uto.
A side benefit for me is that if I set it to LTE Only, the phone rejects all incoming calls. That way, if I'm downloading something, a phone call won't interrupt the download.
The unfortunate issue is that it breaks my ability to make/receive calls if I select "(G)SM Only". I'm sure that is because my market is almost exclusively HSPA/HSPA+ for calls.
However, if I need to force LTE, it does it immediately.
I then set to "Auto" for normal operation.
HTH

Looking for a solution for my new used H800K that is now rooted. Sadly *#546368#*990# does work on my old Hong kong model that I am leaving yet *#546368#*800# menu does not show Field Test, although my H990N can do it in the menu so I always had it on 3G only because radiation is very low compared to 4G, and even 2G is higher then 3G as testing. 4G is nearly always in the RED!!! Whereas 3G is in the GREEN nearly always.
Also helps not downloading to fast to burn up the mobile and make it slow.
So... Looking for a way to get only 3G on my H800K... Sad with all the nonsense they do to phones and waste so much time of ours. Tyrants is what they are, coding Tyrants!

not receiving incoming calls...

just got the phone yesterday and updated it to the P beta. everything works amazingly well for a beta in my opinion, BUT i cant receive calls. outgoing calls, texts, web and apps are just fine.
spent almost 2 hours at tmobile flipping all the settings around and no luck. any ideas would be appreciated.

Same issue here bro...Incoming don't ring but I get voicemail notifications.... Really annoying, even if it is a DP.

Turns out the beta doesn't play well with the essential LTE. Switch to 3g and calls will come through. Hopefully it doesn't take long to find a work around for it

I believe the people having this issue have volte enabled...try and disable volte (it's broken anyway and more than likely why calls won't ring through) and see if that works

Got same issue... My experience was that I could solve the problem with reboot.
Issue came after playing on settings for mobile network.
Is meaning, when you do this you have to reboot afterwards otherwise you can't receive calls
Try it.

Tried rebooting multiple times while changing settings around. The only way I can get the calls to come through is by going without LTE completely.

Settings/network settings/mobile network/advanced/enhanced LTE?

I had the same issue and to fix mine I just enabled Wifi Calling.
When on wifi I didn't get a call, just missed call notification. After enabling wifi calling, it comes through without issue.
I tested calling off wifi and on wifi and all calls come through good now.
This could be similar, so you guys might want to look at that also.
Good luck!

Heard from a few that this was solved by going into phone app settings -> calls -> calling accounts, then turning on "receive incoming calls". Seems it's disabled to save battery? Can't confirm as I just flashed to try it out and then went back to 8.1 because I like themes too much. Lol.

I'm on Sprint and was never able to make or receive calls regardless of Network settings in the easily accessible options menu.
The following fixed my issue. You can access this menu without downloading an app but I forget how so it's easier to just download the free app https://play.google.com/store/apps/details?id=com.xsquarestudio.forcelte
I had my network mode set to LTE/CDMA when first using this app, and somewhere in the middle I changed it to CDMA but I'm not sure how much that impacted the actual fix.
These were my steps. I'm not responsible for any damage this may cause to your device as I'm not sure if messing with these settings is foolproof or not.
First, opened previously linked app "Force LTE" then under "Set Preferred Network Type" I changed to CDMA only. Enabled/disabled airplane mode. This seemed to do nothing as LTE was still showing in statusbar.
I then chose CDMA auto (PRL), airplane mode on/off, didn't seem to do much either. LTE still showed in statusbar and couldn't make calls. Also "Voice Network Type" showed "Emergency Calls only" inside the app.
I then chose the 3 dot menu and chose "select radio band". I changed that to United States, without resolving problem. Then selected "Cellular 800" and this may have solved the problem, but I continued on and selected PCS, fiddled with some settings in Phones settings menu. Was finally able to receive calls and my signal indicator showed 3G. In app Voice Network Type was listed as 1xRtt. I decided to select radio band once more and chose Class 10.
Calls were still functioning fine. So I went into Main settings menu and changed mobile network from CDMA to LTE/CDMA. LTE kicked in and calls still work!
Again, these settings may only work for Sprint hence the PCS Network option, and I believe Sprint may utilize the 800mhz frequency. The app might show you different options depending on your carrier. I don't know.
Anyway, fully functioning! Woohoo!!

I don't have anything in my settings that says "enhanced LTE" .
Tried using the 4g/LTE and the LTE only options. Neither would let calls through.

I have this problem using the Essential PH-1 with Android 9 Pie in South Korea on the KT network. It should be fully compatible, according to radio specifications, however it only works when I change the following setting:
Settings | Network & Internet | Mobile network | Advanced | Preferred network type | 3G
This is not ideal, since it makes the Internet slow, but at least I can make/receive voice calls. I submitted a support ticket to Essential requesting their official help (I'm well within warranty).

I had the same issue when I use my Att prepaid plan. The problem is caused by wrong network type, you can send text and browse internet, because they use the different channel. My PH-1 wrongly recognized the sim as CDMA/LTE mode, just switch it to 4G/LTE, it will be work. Go to Settings, then search "wi-fi calling", point "advanced" then you can see an opinion "Preferred network type" if you are ATT or T-mobile user, and your preferred network type is "LTE/CDMA“ then your phone cannot make call. Switch it to "4G/LTE", you phone will be work. BTW, Verzion uses CDMA, so if you are Verzion user, CDMA/LTE will work for you phone.
