**EDIT**
Forgot the random outgoing call issue.
Since getting my OP8P, it doesn't seem like any of the radio issues have really been satisfactorily addressed. I'm not sure if there is anything that can be done on our end to fix them, but I figured I'd create a thread to track them, and fix them if possible.
Please include your carrier, or any other differentiating factors:
MMS issues (T-Mobile): MMS messages do not come in reliably or at all with wifi enabled. SMS and RCS messages are not affected.
Fix: (Workaround) Disable VoWifi, which doesn't seem to work on as many APs as the OP7P and prior did. If that doesn't work, turn off wifi altogether to allow messages to send/receive.
--------------------------------------------------------
Wifi calling issues (T-Mobile): Wifi calling will not stay activated. Icon appears for about 30 seconds after turning on wifi. Also seems to be affecting MMS messages not sending/receiving when connected to WiFi, and potentially outgoing calls not going through reliably.
Fix: (Workaround) Possibly affected by APs that allow TKIP encryption method. Reports of only allowing AES/CMAK helping. TKIP has known vulnerabilities, but older devices may still require it be enabled.
--------------------------------------------------------
Wifi connection issues: Wifi seems to go dead 1-3 times a day. Wireless still shows a strong connection, but no data actually passes (SMS still works).
Fix: (Workaround) toggle wifi
--------------------------------------------------------
Poor 5G performance (T-Mobile): While this could be a T-Mobile issue, as they seem to have turned on 5G over most of our area using UHF bands (300mhz to 3ghz), performance is pretty choppy. Uploads seem to be more negatively affected, with speeds less than 1mbps at times. Download speeds can be up to LTE speeds, but often are not, and are almost always jumpy and not smooth during speed tests.
Potential fix: Disable 5G under: SIM & network settings > Preferred network type
--------------------------------------------------------
Occasion outbound call issue: Sometimes making an outgoing call takes 2 or 3 tries. I can't remember the error, off the top of my head, but it's something like "service not available".
--------------------------------------------------------
Can ONLY receive MMS on WiFi calling not on mobile data, SMS not affected. (details here)
Fix: use 3rd party SMS app, revoke all permissions from stock app, disable stock app

You can disable 5G in the SIM and Network settings ??*
With my old phone if I disable wifi it connects to Lte instantly and I can start surfing. With my 1+ now if I disable wifi it takes about 10sec until there's Lte but I can't start surfing. I have to switch from Lte to 2g and back to get it working. Same Sim in both phones

Good grief. I have no idea how I missed that. Thanks! I'll test and update the thread if LTE performance seems better than 5G. This very well could be a T-Mobile thing, since they just recently turned it on in my area.

I have noticed the exact same thing. I'm not sure why it takes so long... especially with dual-channel network acceleration enabled (and the fact that VoLTE is established before I shut wifi off).

My wife and I have similar problems with mobile data and wifi both occasionally showing strong signals but requiring a toggle off and back on before data passage resumes. Both OP8P and OP8. Verizon for carrier.
Well, I guess it's good to know it's happening on Verizon too?
Seriously, this needs to be fixed. If it was just one carrier, I could see it getting out the door. But more than one (very different kinds) of carriers is pretty ridiculous.
Issue: can ONLY receive MMS on WiFi calling not on mobile data, SMS not effected.
More details in my thread here: https://forum.xda-developers.com/oneplus-8-pro/help/receive-mms-wifi-calling-tmobile-t4088673
Fix: use 3rd party SMS app, revoke all permissions from stock app, disable stock app
Updated OP.
I've found that disabling Voice over Wifi altogether seems to help with the MMS while on wifi issues. I still get a few that don't go through and have to shut off wifi altogether, but it's much... much better.
I'm wondering if this is also connected to my outgoing call issues. I'll be testing that also.
**EDIT**
While I still think disabling VoWiFi helps, it is still very much a crapshoot whether or not an MMS message will send or receive. Between this and the dual sim issues, I may need to see if OP will let me return this.
No idea if it's related but in comparison to EE, three is absolutely crap. Truly a horrific network, 50% of the coverage and 59% of the speed.
Have noticed that the phone aggressively tries to hand over to WiFi even when I'm not connected.
Removing 5G from the equation helps a lot, least in my instance.

Curious, how are you seeing it's trying to hand over to wifi?
I'm so upset over this stuff. It would be more tolerable if OP had some sort of official status on some of these issues. Ignoring them won't make them go away.

So it looks for WiFi constantly, also tries to switch between networks. You can disable it

Are you talking about the "Scanning always available" setting? I already have that disabled. I seem to be ok with 5G lately. Pretty sure the bad upload speeds are just due to T-Mobile working out the bugs.

Then you're fine. Don't worry about it.
I thought I'd chime in a bit with T-Mobile 5G. Minus specialized cities featuring higher frequency 5G, T-Mobile nationwide works off of the 600Mhz band, AND REQUIRES the 1900Mhz or 2100Mhz 4G LTE band to properly function at this time. So if you experience poor 4G 1900 and 2100 frequency in your area, but strong 5G, it won't work well for you, and you are better off doing 4G LTE 600mhz instead.
Call your local rep and confirm the strength for those two frequencies for you. Just thought I'd chime in about the poor 5G performance nationwide for T-Mobile for some. Nothing to do with the phone exactly.
My OnePlus 8Pro sometimes disconnects several times a day the radio conection. It's hapend with LTE on Telekom. 5G is not available yet. It's happend also in places where I have very good LTE network coverage.
Restart the cell phone is the only option to reconnect.
Switching OFF/ON the Airplane-Mode, reset network settings or a Full Wipe bring no improvement.
I have already replaced the SIM card against a new one by my network provider (Telekom) to rule out a defect.
I also have no problems with my previous device.
So I'm currently using my old device in parallel with a Multi-Sim.
A network fault therefore can be ruled out 100%.
The latest software version has also been installed.
The crash normally occurs while surfing the LTE network and is noticeable that the Internet is unexpectedly no longer working. The Radio display on the phone show me a few minutes more that i have still connection to LTE and than it jump to "no network" as already described, "ONLY" restarting the device allows to log in to the network again.
It was also tried with intelligent network connection or two-channel download acceleration on and off.
With WiFi the internet works continuously.
The Device runs with Stock-Rom.
I also have contacted the OnePlus Support, but maybe someone here has a solution for me.
Many Thanks

That is crazy. I think they may have fixed the wifi disconnects for me with the latest OTA, but when I did get them, toggling wifi worked for me. I never had to reboot over it. Your case definitely seems worse. Hopefully you don't have a hardware issue.

I have exactly the same issue with the same carrier (Telekom Germany) with 2 SIM cards tested. Gotten worse with the 10.5.9 so I rolled back to 10.5.8 where the issue isn't happening that often. I haven't got this issue when enabling data on my secondary SIM (O2 Germany). I have also tested the new Android 11 beta where I got shortly disconnected from the mobile network and then the LTE+ logo changed to "g" and everything was fine again. The phone was still connected to LTE with full DL speed (did the whole initialisation with mobile data + 20gb music download). However the beta is not usable at this stage. Since I have an unlimited data plan on that Telekom Sim I cloud test the **** out of it and it seems that the disconnect happens when the phone tries to change or adds the cell connection while using data. I have sent OP the required logs and after that they ignored me.. hope they going to fix this as it seems to be a software/compatibility issue with that certain carrier. Also 10.5.9 isn't really coming to German devices with ota so they might know about that issues.

Thanks for the feedback.
That the Problem with 10.5.9 got worse i can confirm. I loaded this Version in Germany by using the Oxygen Updater. But that gives hope to me that it is really just a software issue and no defekt on the device. So I will not send the device to OP for an unnecessary repair in the hope that there will be fixd with an update soon.
On the Facebook Oneplus page I have already heard from some people they have exactly the same problem, all of them use the German Telekom network.
Hopefully you get right, with that presumption, that 10.5.9 isn't really coming on German devices because they know the problem. So the fix will come very fast.

You guys haven't heard any buzz about 10.5.10 yet? I'm on 10.5.10 in the US, which I feel has been a lot more stable than the previous two versions (which had alternating issues for me).
The biggest issue affecting me remains the issues sending MMS while on wifi.
After a phone restart, VoLTE/4G Calling and Wifi Calling work for a short period, then stops working, usually after moving around between mobile towers and/or wifi hotspots.
I find it happens whenever the device loses mobile signal, or when the device flips down to 3g and then back to 4g, 4g data service returns but both VoLTE calling and WiFi Calling remain disconnected despite being enabled in settings.
This happens on my primary SIM only. I have a second sim in my phone at the same time which works perfectly with both VoLTE and wifi calling. I upgraded from a Mi 9 phone which worked perfectly with both these SIM cards.
Looking at the device logs (With Logcat reader), I get lines like
QImsService] ImsServiceSub : [0] Permanent IWLAN reg failure (IKEv2 auth failure)
I also see
IKEV2ErrorReceiver] Canadian configure is not set, return
Other things I've tried:
Updating to the latest MIUI version (12.1.5.0)
Network settings reset
Only using the one sim
Removing the second SIM
Clearing all caches
Clearing caches and storage of things like CneApp, Carrier Services, Phone Services, Phone, anything carrier related
Resetting APNs, adding APNs with bearer set
Setting phone to prefer 4G/LTE (ie do not connect to 5G)
Removing my VPN, same problem with VPN installed or not installed.
Removing sim cards and leaving phone off for a while (an hour or so)
Getting a replacement SIM
I have not tried a factory reset yet, as I am not confident in being able to back up the phone fully and other threads with similar issues suggests that won't solve the problem.
One way I've managed to get it stable is to dial *#*#4636#*#*, go to phone and set preferred network type to "NR/LTE". The phone does not connect to 3G or below in this mode, and unfortunately this setting gets reset when the phone restarts.
At this point I think its a problem with the MIUI software version itself, or some firmware driver that comes with these versions of MIUI. I'm hoping MIUI 12.5 will fix it, but I'm wondering if anyone else has seen this issue or knows what else I can try.
Upgraded to 12.5.1.0(RJDEUXM) and the issue is still present, also tried asking my operator to completely reprovision the line with no luck.
I guess I'm stuck with this behaviour until I upgrade my phone
STEP #1) See if VOLTE works normal when switching towers with a different phone.
If it does then you can try the things below, if it doesnt maybe it might be the cellular carrier issue.
If other phones work find then please note that VoLTE mainly works on 4G LTE ... donest work on 2G or 3G and may or may not work on 5G depending on your carrier. Find out what NETWORK BAND your phone is using when VOLTE is working. You can use a app like
Network Cell Info LiteOnce you find out the band you can then use a script or use a app so it stays on that network BAND. A little more advance but it may also possibly be a DNS issue in the tables during the change of towers during the reprovisioning... you can try a script to flush the DNS and reload the tables when the network info changes or bind them statically for testing purposes.
Still doesnt work it may just be the firmware's modem issue with that phone in the way it handles re-provisioning process during cellular multiplex switching.
I have terrible cell signal at home, so rely on wifi calling to make my phone function as, well, a phone. However, recently something has changed where WiFi calling no longer appears to work even though I have it enabled. Actually, that's not strictly true, it works, but only randomly and seems to not be available the majority of the time.
Previously, as I could often get 1 bar of signal, what I would do is enable airplane mode, then turn wifi back on to get wifi calling working. However, this no longer works. I have reset network settings, re-enabled and registered Wifi calling, checked with my provider that Wifi calling is available, used the Samsung Band Selection app to set to prefer using Wifi calling over cell data. I'm sure there are other things I have tried, ultimately, nothing seems to work.
Wifi speeds are good, I'm at the end of my rope with it.
It's a Sprint (T-Mobile) phone, still on a Sprint SIM here, spent an hour with support yesterday and they basically had me repeat everything I have already tried before telling me they will have to escalate it.
Anyone else having issues? Any idea what to do?
Thanks.
Not sure if this will help, but you might want to look into what port wifi calling uses and make a port forwarding entry in your modem. I just remember long ago when tmobile had their TM-AC1900 router,something about it having certain ports open to allow for wifi calling. This was before they released their 4g lye personal cellspots.....this was a wifi cellspot

These may help.....
P.s i have Xfinity for home internet and tmobile for a carrier.....my wifi calling has been weird at times out of the home while connected to Xfinity hotspots......and long story short, now that Xfinity has their own cell service they may be crippling ports....just a thought....manually forwarding those wifi calling ports should fix that if that's the case....
Is wifi calling working for anyone on pro or regular P6? For myself, and quite a few others in some reddit threads it is not.
I've checked all my settings, and they all appear to be correct. But when I try to make a wifi call, I keep getting told that the network is not available. I'm able to browse the net over wifi on the phone w/out any problems. I'm also able to use google voice to make a call over wifi, but not the regular phone app.
I'm on GoogleFI with the FI variant of the phone -- have contacted support and was told the issue has been escalated. Has anyone run into a similar issue on the P6/P and found any fixes?
I got an unlocked pro and wifi calling is working for me on AT&T
WiFi calling working on Verizon with unlocked Pro for me.
Guess I should make this more specific -- I have the FI variant, on GoogleFI. It appears that everyone else who is also having this issue is also on FI
Wifi calling works great on TMobile with unlocked Google variant.
I'm on Google Fi, bought mine unlocked from Google Store. I have one spam call answered by Call Screen on WiFi.
EDIT: Just placed a call to a movie theater and it used WiFi.
Guess I'll pickup a normal unlocked one from BB and see if that works any better. Have basically 0 reception at home, so wifi calling is a must.
6 & 6 Pro both working with Wi-Fi Calling here (UK BT Mobile)
Sounds like an issue with Google fi.
Working flawlessly here on ee-gb
6 & 6p WiFi calling fully functional (UK EE)
Unlocked 6P on Verizon Wifi calling 100% fine.
No issues with WiFi calling for me on the Google Fi on P6P.
It works for me but not on every wifi network. When I'm at home I never see the wifi calling in the top left but when I'm at work I see wifi calling in the top left.
