Unable to call. - Nexus 6P Q&A, Help & Troubleshooting

Hey, I was on a February build of pure nexus till yesterday, and for the last 3-5 days I was unable to call out. Upgraded to the 3-15 build, updated gapps, tried installing MMB29V and "outdated image" so I tried MHC19I, Seems to work. Solved the internet connectitivy, but now I am no longer able to call out or receive calls (auto sent to voicemail). SIM issue? Try a different ROM? Return to stock?
Only apps I use that might affect phone are greenify, tibu, and Cerberus.

Tried freezing google fi (unsure how that got installed.) No dice. Also mentioning that calling cuts internet

No calling, only SMS/data/wifi working on any ROM and/or stock

I've been using AICP for a while (Marshmallow), but haven't done an update in a while. By a while, I mean that I don't think I've flashed anything in weeks. Suddenly, I cannot make or receive calls today. Yesterday I made a number of calls just fine. I checked all the standard possible causes, dialer apps, default apps for phone, etc. After no success, I decided to flash back to stock.
Now I'm on stock 6.0. Same problem, cannot make calls. All I get is a screen which says "dialing" until it makes a tone sound and hangs up, never rings anyone. My phone never rings or responds when other people call. I do have full bars and service, and my APN is set up properly with AT&T in the USA. SMS and Data work fine, and so does WiFi. No other problems at all with the phone. I've had it for about a year and a half with no real hardware issues other than a loose charging port. No drops, no cracked screen or anything.
I'm wondering if anybody has a clue about what the problem with my phone is. I'm willing to generate and provide logs if there's a way to do that which could show the issue.
EDIT1: Derp, just tried the SIM in my girlfriend's phone. Seems to by my sim card. I'll go to AT&T tomorrow and report back here if the issue is fixed.

[SOLVED] Verizon MMS Fails to Download All of a Sudden

I'm running Clark stock 6.0 build MPH24.49-18/unlocked/rooted/xposed on Verizon. Build is fine, was fastboot installed direct from Moto's firmware package back in September and has been running flawlessly. All of a sudden I'm not able to receive any MMS messages. My primary SMS app is Signal so I tried Google Messenger and the stock messenger app and all of them are failing to download any MMS. This just started happening a couple weeks ago. I'm not convinced that this is a rom or any customization that I may have done issue, I think it's purely something with Verizon or maybe an APN issue? It's just weird that this just started happening out of the blue. Before I contact Verizon I figured I'd ask here if anyone has come across this.
I'm on Verizon n no problems.

Had this happen once about a year ago on the stock rom too. I hadn't made any major changes and the phone stopped receiving MMS. It had been working fine for at least a month prior. On AT&Ts network for me.
Restoring a nandroid backup fixed it, but I never did actually figure out what went wrong.

So the backup restore fixed it...? So strange. Now I must figure out what is causing this.

I was rooted with a custom kernel, but had been for weeks with no problems. Then mms just quit working.
Didn't do much troubleshooting, sorry. Restoring the backup fixed it and it's never happened again. Could be a coincidence, but sounds just like what you described.
I've had this happen a few times, a power off reboot usually fixes it. Verizon, true pure x. I've been to stubborn to reload to see if it fixes it permanently.
SOLVED
The issue is with the APN settings. 2 Lines were incorrect:
-MMS Port was set to "not set", it needed to be "80"
-APN Type was set to "default,dun,supl", it needed to be "default,dun,supl,mms"
Very strange that these configurations magically changed themselves. What's even funnier is that Verizon customer service told me that the issue is that it's a non-Verizon phone and the only thing they could recommend was a factory reset and/or a new sim card. They also would not give me the correct APN's, they said some nonsense about that information being unavailable to them. So Google fixed this issue for me. FU Verizon.
I have had mixed luck with different APN settings. The above worked for me for a while, and then inexplicably stopped. I tried a bunch of different configurations before sticking with the settings in the attached screenshot. These settings worked for me on Marshmallow and continue to work on Nougat (7.1.1). These are also the settings that appear after resetting my network settings from the Mobile Networks menu. I hope this can help someone out.

Android 8.0 cant receive texts/sms

I have a rooted Nexus 6p. A few weeks ago I flashed the factory images of Android 8.0 Oreo to my 6p. Flashed TWRP and rooted with magisk. For about a week or so everything was fine...then approximately 72 hours ago I could no longer receive text messages from anyone. I can send texts just fine I just can't receive them. I have full bars of service with 4g LTE. I can surf the web, use Facebook and any other app requiring data. I can make and receive phone calls.
I've tried everything. Removed the sim, rebooted, checked APN settings, cleared cache, wipe data, tried various different SMS apps. I even wiped the device and reflashed Oreo via fastboot again. Nothing.
I called TMobile they have no idea what's wrong. I called Google and they were of no assistance.
I'm going to try and flash the last nougat factory images later from Google and see if that helps. Before I do that I wanted to see if anyone here could offer some suggestions I haven't already thought of.
Thanks!

I would go get a new SIM provisioned for your phone at TMo for free. Are you pre-paid or post-paid?
I was planning on it. However around 0930 this morning all of my missing text messages came flooding in. SMS seems to be working fine now. Would still love to know the trigger of this issue.

Cool. Likely a carrier/plan issue.
You didn't happen to have an Ad Blocker installed? I had the same issue on a different phone, and that was the culprit.

Yes. I use adaway and adguard. Never had an issue with them not allowing me to receive texts. I'm also running both right now and sms is working fine.
Did you restore messages with titanium backup? If so make sure you have switched messaging back to the default app. Had the same happen to me.

Well adaway definitely was blocking my SMS. As soon as I removed it and rebooted phone the msgs came flooding in.

Adaway is a host file fetcher. It has nothing to do with SMS and does not interfere with it. Try it again. It's the best one out there.

Not getting texts / calls (T-Mobile)

Hello,
Once I got this phone a year or two ago, I've found that I will need to reboot it to start receiving texts and phone calls at times.
This was on the stock ROM, I've used CM 13 and now Lineage 15 since and the behavior is always the same.
There is no indicator I've lost cell service and my data connection will work fine regardless.
Because this is my first ASUS phone and also my only phone I've ever had on T-Mobile, I don't know which of the two (possibly both?) to blame.
Has anyone else experienced this? If so, was it with another carrier? Is it worth going back to stock and getting the latest updates? If I knew it would resolve the issue, I would definitely do it.
Any help you can provide is greatly appreciated.
I'm on a Z00T (ZE551KL) if that makes a difference.

Update:
Reverted back to stock and got on the latest OTA from the ASUS website, the issue still remains.
Anyone out there using this phone on T-Mobile? Its really starting to become a problem, I'm completely missing important phone calls and texts with no way of knowing until I force my bank app to send me a text, and I don't get it.
A reboot resolves the issue, I have no idea what triggers it.

I have SM-N900V (Note 3 on Verizon). Running LineageOS. If I'm home or at work no problem. An hour or two away I don't receive texts. I can send them, but until I reboot I receive no texts. After rebooting I usually get them twice. Calls seem unaffected. Did you figure out anything with your phone?

1. Clean up your sim contacts with https://en.wikipedia.org/wiki/Isopropyl_alcohol
2. Use the nexus 6p factory image from the google website and run the flash-all command after you have backup your data to reinstall your whole phone
It should work again
