Sorry for the long post
I’ve had the 1+ since 2014 now, I am rooted and have used various Android 7 and 8 (recently) roms on the device until recently (probably 7 months ago) my 1+ started playing up. I would not get any signal whilst at work; although the building I work is generally poor with mobile signal however I use to get just enough signals to receive a call.
About 7+ months ago this started fading and I would get 0 bars, at first I thought it’s a modem issue so I tried all the different modems and made notes on which one was the best but in the end none of them helped with the situation. I then did what most people do and googled the issue and found that there are lots of other people with similar issue with the oneplus one not working on LTE, many suggested to make sure I visit the engineering menu *#*#4636*#*# and change the connection to LTE/GSM Auto (PRL), however this was already set and yet it was not making any difference. The main issue was not being able to make or receive calls when the device is connected to LTE.
On the odd occasion I was able to make/receive all on LTE when leaving the building but it would be not stable, at times I would get a call but people could not hear me, then sometime I would dial out and the screen would be stuck at “dialing” and nothing would happen. Then I would try few times and it may work or not work at all. So I switched to GSM only (via the secret menu) and the phone would work perfectly, no issues calling out at my work desk or outside and getting all calls without any issues. The issue with this was that on a reboot the settings would go back to LTE/GSM so it was a constant change. On top not being able to use 4G Data speeds was making life harder.
Even when selecting 3G in network settings the phone would not switch to 3G only. I also tried different network provides like 3 UK, Vodafone but still the same issue.
I’ve now come to a conclusion that this is something software related (perhaps?) as the device is failing to switch to 3G when making/receiving calls. When I check the secret menu I see that DATA and VOICE connection is LTE. Now I know this device does not support VoLTE so I thought it would always first aim to connect to 3G signal?? NO?
As a result i’ve moved to Pixel 2 device because I tried everything from different roms to modems, going back to kitkat, CM12.1 and 13 as well as Oxygen OS but was still getting the same problem.
I’ve also come across posts (on google) that people with different oneplus device are suffering from this so not sure if something has been switched on/off on my phone when flashing different roms to have caused this issue or is this a hardware problem?
I’ve spent numerous hours trying different things suggested by many on google but haven’t got anywhere. I have given up trying to get to the bottom of this.
If anyone is out there who have had this issue and have found a solution please let me know, I still very much like the oneplus but with this issue it’s hard to use the device.
Thank you for reading…..

I can relate to you. have similar issue and also tried most of the things you have done. don't know what to do. if you have found something, then reply.
I think I have the same issue here in Italy too.
I tried all modems in the list and downgraded to kitkat but with no luck.
same issue reproduced on lineage os 16.0 India /Airtel

No calls incoming/outgoing over LTE network lineage os 16.0, when changed to 2G network calls works just fine
while LTE no issues with Data connectivity .
any luck for anyone.
Thanks
I don't have the phone anymore (in fact, the same issue made me get a new phone), but maybe try updating the modem?

I've tried CM 7, 10.1 and 10.2 on my Galaxy S 4G (SGH-T959V).
I invariably get this problem where during calls, the audio cuts in and out (approx. every second word in a conversation is lost). Sometimes there's no sound at all, and I've had incoming calls not get through too.
Also, there are problems with 3g. Typically it doesn't work at all (on CM 10.2 it does work sometimes), and the only way to get mobile internet working is to enable the "Use only 2g networks" option in the Android settings.
In CM versions prior to 10.2, I wouldn't even be able to see any of my APNs in the list, or be able to add any, unless I had selected this 2g option, at which point they would magically re-appear. in CM 10.2 I am able to have APNs in the list and 3g works for a while, but then stops working. Needless to say, I've been double-checking my APN settings.
I've also tried a bunch of different modems, but it makes little or no difference. I got the modems from here:
http://forum.xda-developers.com/showthread.php?t=1192436
Any suggestions? I take it that the behaviour I'm experiencing is not normal?
Seems like the radio of your phone is messed up since you've tried many modems and ROMs. Did you get good signals on stock GB?
Yes, confusingly I've got no problems at all on stock roms of Android 2.1.1 and 2.3.6. I've switched between these and CM many times, and the behaviour is completely consistent - calls and 3g are dodgy on CM and fine on the stock roms.
Anything else I can try? I'm in New Zealand, and the phone is imported from Korea I think. It's branded T-Mobile, and is a SGH-T959V.
No ideas? Other people aren't experiencing this same problem though, right?

none here....sorry!
It's a weird problem for sure. I would guess hardware, or a sim card issue. Maybe it's just bad service. Not many people would know if the problem were specific to New Zealand.
Having some issues with receiving calls and SMS on my OPO when connected to my home wifi router, I have searched forums and official OPO forums bit have had no luck finding a solution.
Im from the UK and use virgin mobile (uses the EE network), router is the virgin superhub if that makes a difference
Problem seems to have been happening since I got the phone (begining of Dec 14) but I only became aware of it around new year, girlfriend has an OPO also and does NOT have this issues.
Phone is the global model running stock cyanogen 44, android version 4.4.4
Any help would be appreciated, struggling with this one
Thanks

This has been an off and on again issue for many devices since 4.3 was released. I did a google search and Nexus 5 was plagued by this. There's a long thread on the google support forum, with several OPO posts. The thread is more than a year old, and no root cause has yet been discovered. There appears to be no rhyme nor reason regarding who gets it and who doesn't. I have had this happen intermittently, and a reboot usually solves it. For those who suffer this chronically, the only work around seems to be to keep the phone on 3G preferred. Don't let it connect to LTE.

Yea I found some people talking about the issue on other devices, seems really weird, and yea I did change the preferred network setting to 3g (was previously set as 4g which my network doesn't provide me with) and it worked for a while, however seemed to start again recently, will search for those threads and have a read, thanks for the help
Any other info from people with this issue would be helpful too,
Is it possible that changing my routers broadcast channel would make a difference, could it interfere with the radio?
Thanks again
Still having this issue, yesterday I reflashed stock cyanogen 44 via fastboot method and problem is even worse now, the issue seemed to be every now and again but seems to happen every time now
No longer receiving calls when connected to 3g and WiFi either, only workaround seems to be if I switch to 2g mobile services and I'm still able to receive calls on WiFi
Is there an easy way to make my phone auto switch to 2g on WiFi (closest iv found is disabling mobile data on WiFi)
Thanks, hope anyone has some more info on this
Edit; found a workaround by using g cyanogen profiles to downgrade to 2g on my home networks, but still looking for info on a perm solution, thanks
I´m having the same issue with Wifi turn on, I cannot make or receive calls.
Let me know if you find a solution.
Intermitent issues receiving calls on OnePlus One when in WiFi
I'm also having this intermittent (Not always!) problem of not receiving calls in my OnePlus One when connected to WiFi. This started to happen after a regular upgrade to Android 5.0.2 (Cyanogen OS 12.0-YNG1TAS17L).
I found the solution in forums.oneplus.net. Just search for: virgin-mobile-uk-no-incoming-calls-with-wi-fi-enabled-and-3g-lte in Google and you will find the link. Go to page 3 on this posting.
The issue is related to the fact that calls fail while in WiFi and LTE. Create at least two System Profiles (Settings -> System Profiles). One to change the "Preferred network type" to 2G when connected to any of your WiFI networks, and another that changes the "Preferred network type" to 2G/3G/LTE when disconnecting from any of your WiFI networks.
Hi,
I have recently purchased a used OnePlus One 16GB Unlocked phone from CEX, and it looks and performs great. However, upon trying my SIM it shows No Service/emergency calls only.
Ironically enough emergency calls arent possible either. I'm with giffgaff, (O2's network) and it would not make/receive calls where I live (West-London). Tried a Lebara sim too, same results.
IMEI number is fine, checked with CheckMend. Faffed about with APN settings, manually connecting to the network, but while I'm home it could hardly find O2's network and even then it shows no service. (usually finds EE and Vodafone but I haven't got those sims.)
Took it to work today and it seems to be working "fine" at work. What I mean by "fine" is that I can make/receive calls, watch HD youtube videos no problem, but download speed from various websites and from the play store would be about 20kb/s and connection would drop every now and then. Switching between 3G and 4G makes no difference whatsoever. Also tried the *#*#4636 options but if I switch preferred modes it doesn't save, it defaults to whatever it wants to upon reboot.
It improves outside of work and it's pretty usable, but it drops just before I get home. This area does have bad O2 coverage but with my old Samsung Galaxy S2 and sh*tty Sony Xperia E1 I always get a decent signal even at home.
So originally when I thought it had a dead antenna, I thought I would return and get a replacement, but upon googling around I found that OnePlus is at war with O2s network on some devices, so I might have the same issue. Flashing isn't really an option as I've never done it and even though I'm within 30 days I don't think I should brick it.
At this point if I get a replacement I might have the same issue, if I change networks I might have the same issue. I have a hard time convincing anyone at work to lend me their sims for a day.
Any advice would be appreciated. :fingers-crossed:

Could be band issue,but as you say it works on work(outside home) then for sure the sim is compatible with OPO bands.
This issue can be fixed by changing firmware of the device.
I know it would be seem hard at first but it's worth the work.Flashing firmware can greatly increase your signal strength and likely to cop out any issues with data and calls.
But first you need to flash Custom Recovery Twrp and before that you need to unlock the bootloader of your device.
To start with,
https://forum.xda-developers.com/showthread.php?t=2788632
You don't need to do the root section,just the bootloader unlocking then flashing Twrp.Its easy.
https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907
Here's a firmware compilation thread just try them and use the one which suits your carrier the best.
Good luck
Hello all,
Phone: Mi Mix 2S
MIUI: Global 9.6.4 Stable
Model: M1803D5XA
Carrier(s): T-Mobile(SIM1) & Verizon(SIM2)
Issue: MMS receiving is limited to 30kb when using the stock Xiaomi and Android Messages messaging apps. APN settings do not show on device for Verizon SIM(doesn't matter if in Slot 1 or Slot 2).
So I called Verizon and worked with level 2 tech support to try and troubleshoot this issue. Basically, the MMS and/or Device server on Verizon's end cannot verify the device and therefore limits MMS sending to the device as it cannot authenticate. This verification is done by verifying the IMEI of the SIM and the device identification.
So basically level 2 tech support cannot verify the device manually and cannot submit a request to add the device information either, it has to come from the vendor(Xiaomi) to Verizon.
Anyway we can request this from Xiaomi going forward? Seems weird to have all the bands for Verizon, can get full 4G LTE coverage but I can't receive more than 30kb per image.
I had this issue at first. Flashed latest stable and it was fixed. It's fixed on miui 10 beta and its fixed on treble builds

Well I flashed to 9.6.4 stable, which I thought was the latest stable?
I'm flashing MIUI 10 right now...guess we'll see what happens.
*Edit, still not working on Verizon. And now on MIUI 10, Dual 4G is broken.
*Edit 2, now I have Dual 4G back. Verizon needs to be SIM 2, but be the default for Internet....
I'm on VZW only and I'm on the latest MIUI 10 beta. I'm experiencing this as well. My wife receives good quality images from my phone but when she sends from her Pixel XL to me they are terrible. As are images I receive from anyone else. Kind of a bummer.
Are you guys having issues getting connected on Verizon now? I'm not able to reliably connect at all, most of the time it just sits on 1xRTT on VOICE, and won't connect to data. I can get it to connect to LTE/VOLTE by smashing airplane mode or disabling radio over and over again. Occasionally it will go to LTE, but it doesn't stay working and drops out. I can't drive anywhere and even conduct a phone call as that doesn't stay up either. When it drops, it hard drops and acts like the modem is being reset, instead of roaming to a new cell tower.
Edit, forgot to mention, called VZW, they gave me the finger and tried to sell me an iPhone XS Max 512GB as a "suitable replacement" for my 8GB/256GB phone. They were not helpful, and told me that they have "teams taking steps to make uncertified phones not work on Verizon's network for security and safety reasons". I have tried two different sim cards as well, both with active service and both work in all 3 generations of Pixel XL that I have.
Why the hell would Verizon troubleshoot a phone they haven't certified for their network? Quit complaining.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.
I have been struggling for days with my Verizon connected Mi Mix 2s. At times I could connect with VOLTE but I lost my MMS. This past weekend I tried various ROMs with no difference. I finally cleared everything, loaded TWRP and then flashed the Global developer beta.
I also put my SIM back into a phone that Verizon would recognize and reset the card.
When I was up and running again I did the *#*#86583#*#* to unlock VOLTE and then the 4636 dial to set LTE only. So far so good. I was then able to go back and add a correct apn for verizon. With Verizon Messaging app everything is working and stable, including MMS. Afraid to mees with it again. But it is possible to get the phone to work with Verizon.

Hi - is your SIM a newer (or brand new) SIM? I am seeing something in the logging on the radio logs that the SIM doesn't contain any carrier information, and was also seeing several errors about missing CMDA specific settings. This weekend I spent most of the day on Saturday and Sunday testing build.prop edits, and messing with the apns-conf.xml file settings. I could not get anything other than 1xRTT most of the time (I modified one of the existing entries in the list of APNs to be an exact match of what my Pixel 3 XL has) and by forcing LTE Only in *#*#INFO#*#* I was able to get LTE for brief periods of time, but not consistently. On 8.11.29 and 8.11.23 builds I can't get data working consistently, and if VOLTE isn't turned on, I can't get it to even act like it's going to connect LTE. I checked the APNs and played with it for hours, but not much success. The device just seems to "connect" but if you try to call on VOLTE or use LTE data to do something, the radio appears to reset. I am wondering if someone at Xiaomi neutered something in the RIL setup for their builds that broke CDMA compatibility. When I have time again, I will do some more comparison to see if I can figure out why it's not working. I'm planning on decompiling some of the files in question and looking at the code and configurations to see if something in there is the cause. The radio logs do not have a smoking gun. I also grabbed a copy of the build.prop file from MIUI9/Oreo and I am going to compare to see if they have some kind of prop flags that are missing in the MIUI 10 builds and or PIE builds.
I am going to find a way to make this phone work on Verizon.
Eventually, I rolled back to MIUI9 on Oreo (I don't know the build off the top of my head and the phone isn't near me) via fastboot. I have been able to get decent connectivity with that software version on Verizon where I live. I had to create my own APN, and have been using that with limited success. I submitted a bug report on the MIUI bug reports page. If you want to upvote that bug, the link is here: https://en.miui.com/thread-4724630-1-1.html
Edit: I just went to lunch and couldn't get the phone to connect to anything but 1xRTT the whole time we were at lunch (I didn't force LTE only, as I haven't had to previously since I rolled back). My next steps when I have time is to compare the build.prop between the builds, but I am not expecting to find anything. I am starting to suspect from the differences in the way the logging looks that they may have messed with the code or config information for the the RIL setup in the Android before they built it.
Please keep posting what you try, I'll be following with interest! I had everything working for a while but since MIUI 10.0.6.0 mms has broken.

Can you get data and phone services? Mine won't stay connected, but that could be a hardware problem.

Yeah, data and phone have been fine so far, I think a few times it's disconnected but messing with the APN has fixed it. In general, I'd say my data and phone have been pretty stable. MMS on the otherhand, I had working for a bit on 9.6. On 10.0.4.0 it's been really slow to send and receive or not working at all. When it did work, picture quality was awful.
PS, I have my phone set to Vietnam by mistake. I have an older SIM card, at least a few years.
PS still working fine.
Mine has been repaired, they had to resolder a connector for the antenna on the board and the logic board was dropped. I saw this happen, however, signal levels are as good if not better than the pixel devices in the same spots for me, so I don't think anything is permanently damaged. I've been debating trying to order another Mi Mix 2 from somewhere or ordering a Mi Mix 3. I have built roms and have a lot of android troubleshooting experience, and I can't seem to figure this one out. What I am seeing on my device is that once it is connected, it seems to not want to roam properly. Like disconnecting from one cell causes a modem reset and then it takes a long time to reconnect. I am going to keep working on it though.

So you had a hardware issue? After the fix, which things work and which don't work for you? When I disable VoLTE carrier check, I get the VoLTE symbol, but I can't make any calls. I've been messing with the SMSC, where it seems changes aren't persisting. I can't get mms to work anywhere but the stock app, which sucks because the stupid MIUI stock messaging app doesn't have group mms >.>
I had a screen break due to it falling on a very sharp corner of an object from about 6 inches up. I took it to a phone repair place locally. They dropped the logic board, camera, front facing camera/charging interface board as well from like 4 feet up onto concrete. The person who tried to repair the screen (which I provided the replacement for) did not follow the instructions on the video either and removed the plastic lining bezel from the phone body (you are supposed to remove the screen from the bezel with a heat gun). They had to send the phone out for micro-soldering to re-place and reattach the antenna connectors for the cellular and wifi antennas. They had to pay for that. I know what the phone looks like inside from watching the videos of how to replace the screen. When they gave the phone back, there was a substantial gap between the edge of the screen and the bezel in a couple spots (atleast 3 or 4 sheets of paper thickness). I ordered a new frame, bezel and screen all in one and replaced it myself (moved all the components from the original phone body to the new one). Everything appears to work, signal levels are good, but the cellular part will not stay connected, and the modem acts like it's resetting all the time. Sometimes it will stay connected to the repeater in the office I work in for 8 hours straight with no issues, and I can text and call. When I leave that area or go home, it doesn't seem to want to roam to service, and instead of switching cell sites it seems to just reset the modem. There is absolutely a possibility that some small transistor, resistor, cap or something else on this board got damaged when it fell. Given that you guys aren't reporting issues with your devices staying on the network, I'm starting to think I need to go back and make some serious noise at this repair place. I am no stranger to working on sensitive electronics, and I was extremely careful not to damage anything inside when I moved the components (and it was already exhibiting this behavior when I got it back from them before I took repairs into my own hands).
That said, I've spent the last two days trying to figure out if I can do anything that might be helpful with QPST and QXDM as well as playing with various additional build.prop configuration. Nothing there that seemed to help. Rolling back to MIUI9/Oreo seemed to help some but was not a magic bullet. I still had to manually configure APNs and find myself needing to reboot or airplane mode every time the device should roam to a new cell site. I am planning on trying to copy the "carrierconfig.apk" file that is part of the system settings off of a Pixel 3 XL onto the Android Pie MIUI10 beta to see if possibly Xiaomi has something jacked there, but since you guys aren't reporting issues, I am seriously starting to suspect that something is physically damaged after that drop on the logic board, but the intermittent behavior and the fact that the signal looks correct and normal when it's working is going to make it nearly impossible to identify the cause.
As a side note, there's a Mi Mix 3 on it's way from GearBest....

So you had a hardware issue? After the fix, which things work and which don't work for you? When I disable VoLTE carrier check, I get the VoLTE symbol, but I can't make any calls. I've been messing with the SMSC, where it seems changes aren't persisting. I can't get mms to work anywhere but the stock app, which sucks because the stupid MIUI stock messaging app doesn't have group mms >.>

So on mine, I can't get it to connect whether VOLTE check is enabled or not. At the office I'm like 10 feet from a repeater, and it seems to connect on LTE/VOLTE (if that's toggled on) very quickly. I have VOLTE enabled on my Verizon account. On the extender, I can make calls on VOLTE, but can't call without VOLTE enabled. I can't get it to connect to VOLTE with the VOLTE carrier check enabled, I have to shut that off and manually toggle. I am noticing massive inconsistencies in the configuration information contained inside the carrierconfig.apk that is loaded in the system build by Xiaomi. I don't see a smoking gun there, but there's a metric crapton of differences.
If I am not next to this Verizon repeater, it usually takes multiple airplane mode cycles or reboots to get onto LTE, it just sits on 1xRTT forever, no texts or data come through when stuck in that mode. Any type of cellular roaming that should happen seems to just cause a radio reset, and it goes to blank bars with X and then it acts like it can't find a network to connect to for a while or goes 1xRTT with full bars and keeps resetting every 20-30 seconds.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.

How is Verizon supposed to support a device they aren't familiar with? This post comes off as whiney. Verizon does NOT have to support every phone capable of their bands, that isn't up to them. Way too many variables using an outside device. With that said, running the latest global beta with the sim card out of my Pixel I have zero issues running Verizon Wireless as primary and Google Fi sim as secondary. Both networks getting VoLTE.

I expect Verizon to use the standards defined for how these devices communicate. I expect Verizon to assist with troubleshooting by providing information and looking at logs as to what my device is doing on the network. This is not unreasonable. I am not asking them to tell me how to fix the problem on a device they don't support. I am not expecting them to just suddenly support a device, but I do expect them to be willing to look at logs and information on their side and provide feedback. I am glad to hear yours is working and am starting to suspect mine has some kind of hardware damage. The local repair place has refused to do anything to help out because "if it's got a signal, it's a software problem".

Well, if it worked before the repairs.. it is definitely a hardware issue.
Check your APN settings. I had the exact same issue with my phone, especially after the latest update. I called Verizon for the customer support and they couldn't figure out as well. Then, I pretty much looked at every settings on my phone and tried almost everything, only to have the issue fixed by modifying the APN settings. For some reason, after the update, the SIM card removed the custom APN settings that I added when I first purchased the phone. Instead, it had the CBS, FOTA, IMS, LTE - Verizon Internet APNs available with the APN set as the CBS (Sorry I'm not an expert, so I really don't know what exactly they are. I suspect that those were pre-saved on my SIM cards as I have used the same one for 3-4 different phones?). Anyway, I googled Mi Mix 2s Verizon APN and set it according to the very first result I found. Since then, the MMS has started working well again. Hope it helps.
I have two brand new moto 5g 2022 phones for me and my wife and they both do everything but work right. You can call someone and they answer but you cannot hear them, as they answer their phone, my phone just keeps ringing while they keep saying hello. Other times it calls and won't even ring.They do all kinds of different things and sometimes even do work but when they do you can hardly hear each other. I should say we got these phones because our old phones did almost the same thing. They were so old they only got 2g and 3g so we upgraded to these. Also I checked the 5g map and it shows we have 5g ultra coverage in my area, also attached the file showing the area.
Thank you for anyone that can help with this problem.

Is this only happening at home? while connected to wifi?
If so try disabling wifi calling.

No it happens everywhere. The phone is on cellular preferred.

I disabled wifi and same result. I have also rebooted both phones and disabled some apps that were transferred from the other phones.
That's crazy because ever since ive had my 2021 version of the phone, the EXACT same issues have occurred since day one. got the phone in Nov 2021 and still have so many issues with Tmobile towers. Tmobile has a huge handover issue with 5g SA and NSA. Old sprint towers that are still up and running on LTE only, work 100% with no issues, all other towers by 310260 that are configured for CA (carrier aggregation), whether its fdd or tdd ca doesnt matter, I have to airplane mode off then on, wait for the tower to connect, turn off data, wait 5 or so secs and turn data back on, go to the debug menu for the phone *#*#4636#*#* and go to phone information, go down to where it says Ping Test and hit it, make sure that BOTH ipv4 and ipv6 are passing the test. If only ipv6 is passing, then repeat the process until they both connect. This is the only way im able to tell if the tunnel is connected correctly to Tmo. I know HUGE pain in the A but that is the ONLY resolution i have found for this, tmo doesnt care, i have had 20+ tickets opened up and not 1 of them were ever resolved and instantly closed the tkt.
People have claimed that after rooting the phone and installing a custom rom with android 12, that all of the issues are resolved, however I am one of the unlucky people with the xt2131-1 device that will not allow anything other than the stock rom to be installed, bootloader unlocked and rooted but will not allow a custom rom. Last Moto phone I am ever buying.

Thank you for the info, I thought it might be t-mobil itself since the old ones and the new ones are doing the same thing. I did get the one phone to upgrade to android 13 but the other one which is the same phone will not. It still did not make any difference.
