Can not connect to 4G/3G.

Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).

*bump*
Any ideas?

Did you put a check mark in data roaming?

I've tried with and without it, it doesn't make a difference anyway.

Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)

Update to full NK2 firmware and see if that will fix it

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?

I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.

4g/Lte no connection after flashing RR

Hello,
since I updated my OnePlus 3 to the newest Resurrection Remix I have problems with LTE/4g. If i activate Mobile Data, i only get EDGE with a low bandwidth. I called my Mobile Provider and they said, that in my area LTE is working perfect. I eject the SIM Card and placed it into another smartphone and after two sec. i get LTE/4g with a high bandwith. A factory reset, returning to Stock Rom, deleting the APNs didnt work either. Is there any soultion fo this issue?
Maybe I crashed my modem ? Is it possible to flash everything back to Stock ?
Thanks

type *#*#4636#*#* in your phone dialer, phone info, scroll down and set prefered network type to LTE only. you will be unable to call while in this mode so do not have it turned on. just test it if your 4g works

well then your phone is broken or your service provider is messing up. but you already called them and they said that it was all ok on their side. so that means there is certainly something wrong with your phone

Cricket WiFi calling, on One Plus 5T

Has anyone figured out how to get WiFi calling working on Cricket wireless on the One Plus 5T. I have it enable, but doesn't seem to be working. I'm sure there has been a work around for this ?? Sometimes cell service in the house is spotty and this would really help missing calls. Any suggestions or work around, please advise.

have you tried installing voenabler module through magisk. That is if your rooted of course Iff it still wont work then your provider may not support it yet.

I'm not rooted. They do support it, but on their own devices not BYOD, but I read there was a work around, so figured I's ask here.

I myself experienced the exact same situation a few years ago the provider I was with had the same policy and after many arguments with there call centre I decided to switch provider to where they didn't restrict the phones functions. Usually in such a situation you need there own bloated firmware to recieve volte/wifi calling. There isn't much of a way out of this in my opinion unless you change provider but I could be wrong. I think they do this so customers buy phones from them exclusively and it's a sly marketing thing. Sorry I couldn't help. It is possible however that by rooting and then installing the module I suggested you could get round this but there's no guarantee. That's if your prepared to root.
Maybe you've tried this already but I found the following.

I had enabled from this link which is pretty much the same way, ( https://shkspr.mobi/blog/2018/08/enabling-voice-over-wifi-on-the-oneplus-5t-and-three-uk/ )

Good luck. Last resort might be changing provider. That's what I had to do.

Sunder, I've done the below before a while back, and it still doesn't work, I have Cricket wireless, so maybe that is why. I have enabled all, but in the status bar the icon for WiFi calling is not showing when WiFi calling is turned on, so I assume it's not connected.

Which network service provider you are currently using means which sim is used in your phone.

Yes, I am very aware of that, and it doesn't work, I've tried it many times, Voltle or WiFi calling icon never comes on in status bar when enabled.

Bro, I think wifi calling is not working in your region Because of the network service provider not staring wifi calling(VoWiFi) technology in your region.
And it may be oneplus 5T is not support your network wifi calling.
In my India, this technique is working and i am using it perfectly with jio and airtel.

That was my point a few post above, where I mentioned it does not work with Cricket wireless, and Cricket does offer VoWiFi, but it woks only with the phones you buy from them. So I was letting people know it doesn't work with Cricket.

Had the same on my wife's P6. The connection would appear briefly, the call sometimes would go through but then connection lost and asked to switch off plane mode by the system. Tried 3 different sim cards, hard reset etc.
Filed a return and her new phone is working as it should now.

That sux, as mentioned an RMA may be needed...

Started happening to me when I updated to v37. It was fine until then. I'll probably flash the old radio image later on tonight.
Edit: nvm, the radio.img is the same between 36 and 37. It is odd that this just started happening in the last 24-48h.

Your wife is lucky.
I've read on the link i posted that a guy rma 3 time with the same issue ....

If someone figures out a fix, please let me know. I am getting desperate here.

Been eyeballing the device ...from LTE to No Service..back to H+ than picking up signal again rotating for about 4-10 mins
Now I'm testing out turning off adaptive connectivity under network and internet sitting inside my office now.

Fixed on my end.
Settings> Network and Internet> Setting bolt icon next to my mobile carrier (T-Mobile)> Access Point Name> Created my own with the same settings from my carrier (T-Mobile) but with "APN type" only having: default,supl,mms,DUN
The rest of the APN stuff seemed to break my mobile data.
Hope this works for others too.

Interesting. Did you contact T-Mobile or Google and asked about this?
This seems like the type of issue that should be easy to replicate.
I would suggest to contact Google either way, since your phone might have a hardware issue (partially defect antenna or whatever) and you need to sort this out, before you run out of warranty and get problems later down the road (fix not working anymore).

Settings> Network and Internet> Setting bolt icon next to my mobile carrier (T-Mobile)> Access Point Name> Created my own with the same settings from my carrier (T-Mobile) but with "APN type" only having: default,supl,mms,DUN
The rest of the APN stuff seemed to break my mobile data.
Hope this works for others too.

This worked for me. Thanks bro!

I started by turning off 2G. Worked for about 3 or so days. Then the issue came back. So, I turned off WiFi calling because I read somewhere that it was causing issues. I haven't had the problem since. It's only been a few days though. FYI I'm on Verizon.
I'm pretty sure it's yet another bug on the long list of them on this phone..

Go into settings > Network and internet > Sims click your provider there scroll down to Preferred network type change to LTE. I figured this out on my wife's phone. You'll loose 5g but it'll get you by temporarily until you figure out a better solution.
