Can't make calls on VZW after switching back from Fi

I decided to give Project Fi a try after the word came down about Verizon raising the rates for unlimited data plans. Long story short, it's not for me. The coverage stinks in the areas I travel. Battery life took a big hit due to it having trouble finding and keeping a signal. I thought it would be better having looked at the TMo coverage maps. Anyway, that's a different topic.

I hadn't canceled my Verizon account so I put that SIM back in and it seems like I am connected to Verizon's network again. All the texts sent to that number came through once the phone was turned on with the VZW SIM back in. However, I can't make any calls. I get an operator error about being unable to complete the call. The Cellular Network Settings only has a roaming setting. Don't have the Enhanced VoLTE option and the other things I had prior to switching to Fi. Did the *#*#4636#*#* thing to try turning the radio off and on, turning on the VoLTE provisioning flag, rebooted, etc. No change in my ability to make calls. Anyone have any ideas what I need to do to get voice calls working again? If it matters, I am on 5.1.1 LMY48T.

VS980 User, Soon to be Switching, Willing to Donate Device to Dev

I have a mostly good vs980, I can't really sell it for much or give it to family b/c the headphone jack is finicky af (touch the headphones SLIGHTLY and it'll pause music/blare browser stuff out of the speaker) and there's some slight wear and tear, so I figured I'd give it to a developer in need. I was planning on donating it to Mike from PA but given PA just shut down and the thread was locked a couple weeks back, I figured I'd just make this thread to see who wants it. Send the word out to any devs you know who'd want it. New phone (nexus 6p) won't be coming in till mid November, so they'd be getting the phone like late November early December most likely.

User Switching

First off this is probably more of an observation than a request for assistance but OMG, stock roms are CRIPPLED! I have no intention of ever using the guest user account on my phone, yet I can't remove it and for some reason it already has 151mb of my precious system memory. Similarly I dont want the icon in my notification bar, but alas, I have no control over that either. Looking forward to root and custom roms!

What controls the switching between 4g and 3g?

I use a Sprint Note4 rooted On OBAR ROM. While at work, my service switches from 4g to 3g very often. The only way i can get it to switch back after it goes to 3g is to either turn off data or turn on airplane mode and off again. It is very annoying. I also use the gtools program and lock it on LTE. It works until i guess i lose they lte signal. Then i lose all connection. So i change the setting ball to lte/Gsm/cdma.
Any and all suggestions are very well appreciated.
Blessings

Not automatically switching to mobile data

Hi, I've had my phone for a few weeks ago and have had this issue since day one, am currently running Oxygen OS 2.1.0.

When leaving an area with WiFi coverage the phone won't connect to Mobile Data (both are turned on all the time). I have to reboot the phone for it to connect every time. It works fine the other way round (i.e. when I return to WiFi coverage the phone will connect to the AP and turn off Mobile Data).

Does anyone have this issue or an idea on how to solve it?

It's an A2001 and my mobile data carrier is Vodafone in the UK.

Phone is constantly switching between H+ and E

So my phone is for no reason switching from H+ to E and then switching back to H+ few sec later...

It's not like I have 0 or 1 bar on H+ it doing it even with 4 bars.. It's pretty annoying I'm on chrome want to open a page and it switches for no reason and I have to wait til it switches back to load the page...

Is anyone facing the same thing?

[Help] Can't turn wifi on after kernel switching

Hello there,
yesterday I was on CM12.1 with Shift Kernel and I felt it laggy. So I changed for SlimKat with Majestik Kernel but I couldn't see anything (no boot logo) and then reinstalled Slimkat with Leankernel and then everything is fine except my wifi. When I turn it on, it says : Turning wi-fi on.. indefinitly. So I tried a full wipe with reinstall without leankernel and still no wifi. Tried to come back with cm12.1, no wifi. I tried *#*#526#*#* and nothing is showing up. So if someone can help me to firegu out the problem would be appreciate!
