M9 Radio Mode Issue - Verizon HTC One (M9)

My M9 randomly switches to an unknown radio mode other than global mode. When it does this it shows a signal but doesn't receive or place calls. Only data is available. After I go back into settings it says would you like to switch to global mode. After I say yes it is back to normal. Is anyone else seeing this issue or have a solution?

I believe LTE only mode cannot place or receive calls

Cellular Network Connected but cannot call nor text

Does anyone have this problem of having excellent cellular network connection but still being unable to call, text or even use the internet? My friend sitting beside me is using the same network so I don't think it's an issue with the cell tower.
The only fix is to enable airplane mode and disable it. And even sometimes, the airplane mode refuses to turn back off and I have to reboot the phone. I've never had such cellular issues with a HTC phone before. Makes me think twice before ever buying one of their phones.
I'm using stock ROM, unrooted.

[Q] Data works, Can receive SMS and calls, can't send?

Hey guys, I was using my phone fine all day, but then a text didn't send. Tried again and nope. I tried calling someone but I never heard a ring. I tried putting in airplane mode and turning it off and on. I even installed a new ROM (clean flash) and still the same problems. I can receive SMS fine but most of my SMS won't send. And my data works just fine .any suggestions? I live right in front of a tower and get full bars BTW.

Update profile and prl and see if that helps

Perhaps your roam settings got jacked. Make sure it is set to "Automatic" and not "Sprint Only"
It could be Sprint, they may be doing updates if your are is set for Vision Network upgrades.

Mobile signal issue

Sometimes mobile signal falls down in cm10.1..it puts in emergency call mode or dead.. Until reboot it returns to normality for a while and then i falls down again.. What could it be? How can i fix that problem? I have always to check my device if i have mobile signal because can't receive calls and messages because doesn't have signal until i reboot the phone.

WiFi not connecting automatically after boot

Hello,
yesterday when testing and setting up the OP3 I noticed that, after booting up, the WiFi didn't connect automatically.
I always had to go into WiFi settings, click on my WiFi and select "Connect". From then on, it worked normally.
(Had to boot really often, so it was clear that it was not a "sometimes" incident.)
Does anyone else have this?
I've had problems connecting to WiFi it keeps coming up can't authenticate connection also had LTE issues so I had to enter the wap details myself and that's OK but on the WiFi I've put a ticket in with one plus and waiting for reply..

With OxygenOS 3.1.3, now I don't have the WiFi problem anymore...
I have the issue where i completely loose data, there is no LTE or H. Flipping airplane mode on and off seems to fix the issue?

1.80.617.1 issues switching from Wi-Fi to T-Mobile LTE

I updated to the 1.53 and then to the 1.80 firmware recently and have noticed that when I leave the house every AM; I cannot connect to T-Mobile (US). Often I must reboot the phone with wifi off or far away from a known signal to properly reconnect w/T-Mobile...I have a signal all the time, just not on their network.
Currently I am using a rooted stock 1.80 based rom and its daily now...anyone else out there experiencing this? Its almost like its the 1.80 firmware itself perhaps?
That happened to be a few times like two weeks ago, but not recently

Same exact problem as you. Only difference is I am not rooted.
Same issue here. Rooted stock 1.80.617 RUU.
I had issues with this yesterday and it turned out to be the wi-fi calling setting

Same issue here. On wifi at home and every morning I leave for work, when wifi disconnects I do not have LTE unless I turn airplane mode on and then off, then I would get LTE back. So as someone mentioned, this is fixed by turning wifi calling off? That's annoying. Not rooted, all stock here.
Same issue here, I've tried changing the wi-fi calling settings but no luck. (I have the T-Mobile HTC 10 and running US unlocked non rooted)

Thought I would let you guys know the 1.81 T-Mobile firmware doesn't have this problem. Even with wifi calling and VoLTE on.
Not sure i have had this issue ever. Tmobile phone running us unlocked.
Works on stk and supported cust roms, I etc..

I've got the same problem. Thought it was a hardware problem so got a different phone...same issue. I like the wifi calling feature, would hate to have to shut it off.
Some people mentioned that if you turn off wifi calling this would fix; I am still having the same problem. Also, sometimes just on wifi is like something messes up and I can't send texts and stuff. I've had people told me that they call me and my phone is like off or something, but it really is not. A simple airplane mode on/off fixes the problem, but this is getting really annoying considering the fact I'm not messing with the phone yet as I am all stock on latest firmware. I might have to flash something soon...

Hi guys,
What was your phone doing(e.g. Idle? Making a call? Playing games?) before you left Wi-Fi area and after you left Wi-Fi area?
It was idle in my case. Since the T-Mobile 1.80 RUU has been release moved on to it...no issues at all. Picked up a OnePlus 3 and mothballed the HTC 10 until CM 13 is under control for it.
I re-flashed the HTC 1.80.617.1 ruu hoping that maybe something had been corrupt during the update but it didn't seem to help the issue for me.
I'm on leedroid now and same issue... Maybe someone knows what's up.
Have this issue as well, on US unlocked running T-Mobile .

BTW, when you left the Wi-Fi area and then cannot connect to mobile data or just has 3G but no LTE ?

No mobile data at all
Same issue here. Leaving work, and disconnecting from Wi-Fi, I haves no cell service. Usually rebooting my phone corrects it.
I'm also having this problem. Seems like once a day my phone says it's connected to T-Mobile but I won't be able to receive or send texts and I'll consistently miss calls that go straight to voicemail for the caller. I'm on latest firmware stock and unrooted.
