[Q] My phone wouldn't connect to 4G

Hi, i bought SM-G900F 2 weeks ago, and my carrier in israel finally supplies 4G.
I tried to connect but my phone seems to ignore the 4G hardware.
I have: baseband: G900FXXU1ANE2
kernel: [email protected] #1
when i enter "more networks" => "mobile networks" => "network mode" the choice is given only between WCDMA and GSM. no 4G.
what should i change / what is the baseband version that supports 4G?
thank you.

in romania card must be changed to support 4g !
check your country, your city and your card. However should support access to 4G network!
you can check this: root s5, install Xposed and active, open xposed, download, search LTE only mode for s5 (G900F) Install and go to settings => networks => mobile networks => network mode and select LTE.

does the "mobile networks" menu rely on the type of sim card?

4g is based on the card and of course signal 4g..... 4g is a difference from the rest network...

as i said in the first message, quote: "when i enter "more networks" => "mobile networks" => "network mode" the choice is given only between WCDMA and GSM. no 4G."
is this MENU dependent on the type of my sim card? this does not look logical to me...

if it does not work as I said above when I have to do the checks said.
menu card has nothing to do with 4g

Thanks, i just noticed that you have changed the previous message...
I did the checks, with the XposedInstaller, but even when i installed the package (LTE for Galaxy S5) nothing changed.
i did the restarts, the installations, but nothing happened, except for "Samsung Health" service to stop.
maybe i should change the ROM?

i did install a new rom and a new modem, the XXU1ANG2, form here http://forum.xda-developers.com/showthread.php?t=2732110, and it works.

[Q] Unsolvable problem with SAMSUNG GALAXY S5's 3G.

Hi,
I am from Bulgaria and I bought a ATT locked SAMSUNG GALAXY S5(SAMSUNG-SM-G900A) from a friend.
At first wasn't able to use my Bulgarian sim card(operator : M-Tel) but then I paid for unlocking code and 5 days later I unlocked my phone.
I put the card into the slot and started the phone. The signal bar was showing full but I was unable to make calls or send messages because of "Not registered on network" message. After an hour of reading the internet I found this code *#*#4636#*#* and then went to "Device Information" and on "Network type I change" it to "GSM only". ( I used the code because in the menu I dont have "Network type" option).
However now I can only connect to GSM network which is the problem because my mobile data is only EDGE NOT 3G. Here I need your help of solving this.
The available option of "Network Mode" are as fallows:
WCDMA prefered
GSM only
WCDMA only
GSM auto(PRL)
CDMA auto(PRL)
CDMA only
EvDo only
GSM/CDMA auto(PRL)
LTE/CDMA auto(PRL)
LTE/GSM auto(PRL)
LTE/GSM/CDMA auto (PRL)
LTE only
Unknown
There isn't LTE network in Bulgaria so I am asking how to use 3G on the phone. Should I root it(not pretty sure how to do it) or something else?
I posted my question in Bulgarian android forum and one guy told me to switch to WCDMA prefered but when I do and try to connect the operator M-tel it says Unable to connect.
So thats my problem with the Samsung phone so I would be very happy if someone knows how to fix this and help me.
Cheers!

Just call your service provider and ask them to activate 3G......I had the same problem, they solved it.

I called the operator today and they told me that other user also complain about their newest models of Samsung brought from USA and it's a software problem and to check for a software update. This didn't sound like a good news. Any ideas? Or i should just wait for something to happen.

[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.

Stuck in LTE cannot make voice calls

Hi guys,
I am with Freedom Mobile - Canadian provider. I've purchased the phone from Amazon, - US version. Connected it yesterday. Worked fine, but had no LTE. I played with some settings and now I ONLY have LTE and cannot make voice calls. Whenever I try to make a voice call phone is trying to connect, but fails in around 30 seconds telling me Network is not available for voice calls.
Was wondering if anyone experienced similar problems.
Additionally, would you mind sharing settings under the below 2 menus, that work for you for Freedom Mobile:
1. Mobile network settings -> "Preferred Network type"
2. In the hidden menu, dial: *#*#4636#*#* under "Phone Information" what is your's "Set Preferred network type" selection?
thank you, I would appreciate your help.

Flash modem from your OS once again. My collegue had similar problem. Tapped something what shouldn't be tapped and disabled 2G, 3G networks. Does Freedom Mobile support VoLTE technology? If not then you will not be able to call via LTE.

Hello there. So i just got a Nokia 6 and i'm having the same issue. Can't make or receive calls but i can send and receive texts and can use the LTE service for data. So i'm supposed to flash what exactly? And any resources i can refer to for the flashing process? P.S: I'm a noob

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.
