Unlocked LG G6 US997 Activation Issue on Verizon with Lineage OS - LG G6 Questions and Answers

I just got an LG G6 US997, unlocked the bootloader, flashed TWRP, and installed Lineage successfully. When I went through setup, the wizard never got past the SIM activation screen so I had to skip that. The service state shows as "Out of Service" with a signal strength of 0. I can't send or receive text messages or receive calls, but data seems to work just fine. I've found that if I place an outbound call, everything seems to reset and then the service state moves to "In Service" and I get a signal strength. After that, I'm able to send and receive texts and receive calls. Tried a new SIM from Verizon... no change. I tried flashing the latest stock ROM (17A) to see if there was still a problem and everything activated without any issues. I was able to send and receive texts and receive calls no without issue. After trying another clean install of Lineage, I'm back to the same issue. Any thoughts?

Same for me
Thank you for posting, I was able to get my text messaging working after making a call. I used TWRP to flash Lineage 15.1 and MindTheGapps.
Any updates on the long-term usability of this ROM?
Cheers

You can try to not use a sim to set it up then use the method that scy gave

Not receiving text messages on AICP or CRdroid nightly dated 2/12/2017

Hello everyone! I seem to be having some bad luck with this device. I recently switched over from the horrific LG G4 to this device and so far I love it! However, when I flashed the most recent of each of these roms I am unable to receive text messages. Any help would be appreciated.
I am on the Sprint Network.
After restoring back to my stock backup I am still unable to receive Text messages. Could this possibly have something to with the modem? Should I flash over the stock modem for 6.0+?
I flashed the Modem from this link and I am able to receive MMS again. Still no text messages however. So for anyone who is experiencing this give that a shot.
Whole issue was caused by Google Voice. So i anyone is having this issue, remove that.

figured out my issue
the device does not connect to any CDMA networks so while VOLTE was connecting and LTE was working on my Verizon sim, the calls wouldn't work and i thought it was a Rom bug, then i went an exchanged the device and lo-and behold, it doesn't make calls on the stock EUI rom either, connects to LTE and VOLTE but the calls don't work.

Us997 lineageos verizon

Just flashed this ROM to check vzw compatibility. It requires you to make a call out after each reboot to get everything (SMS and receive phone calls) working properly. Does anyone know a solution to this? This is the only thing keeping me from running lineage

No calls after flashing rom

Hi,
I recently bought a new galaxy s5 SM-G900F from an amazon marketplace seller and immediately flashed it with lineageOS 16 following the instructions at lineage os wiki -> /devices/klte/install. Everything seemed great until I put my 3 UK sim card in - it recognizes it and shows that I am on the 3 network but with pretty poor / variable signal and phone calls don't work: incoming calls just don't show up at all and with outgoing calls it says it is calling but I don't get any ringing tones and the other side doesn't get anything.
Interestingly for someone calling this phone they get the normal ring tone once and then it changes to the ring tone I would expect if I were calling abroad.
Sadly I didn't take a backup of the software that was already on it and I didn't try it before flashing lineageOS.
Lineage OS showed the baseband firmware as G900FXXS1CQA3. I have since tried flashing new modem firmware to G900FXXU1CQK3 and even full samsung images (latest samsung stock UK BTU) using heimdall - again, everything seeems to work except calls.
Any ideas what I can do?
I would try some other ROM to see if you still face the same issue.

phone says there's LTE service, but disconnects when making a call and cannot receive/send texts

I installed the latest lineageOS 19 version, rooted my phone then ran into this problem where the phone says i have service, but when i place a call it wont fully make the call. Then my mobile data will X out and i get pop up error saying mobile service is unavailable. I then tried lineageOS 18.1 and arrowOS and same problem persists.
formating between installs obviously.
I have looked at every option on this phone and tried combinations and everything in the network/system/ everything and still not working.
The process was actually very simple since i have some programming experience. Other sources mention possible baseband issues? On the fastboot screen it shows a baseband version. all the information there appears normal. I only flashed the boot image one time to root and didn't mess with any other manual flashing processes. Just used twrp. I didn't quite understand twrp at first and therefore didn't get a backup using it... iused adb to make a backup which apparently didn't work so Im lost and hope someone could help me out here. please and thank you!
If i may add I can use mobile data just fine, i can browse the internet and such (with wifi off and data on only) so i really dont understand. Is this a normal issue to have when using custom roms? did I trip some security that blocked me now? any input???
I wonder, though, this moto g7 is an A/B partition thing. so if i understand correctly, flashing twrp would not work and thus why i did not do that. it makes sense. But should i try flashing it, booting into it then installing lineage? even if i did i feel like that would give me same issue considering the method i followed got me into lineageos, plus root checker said i was rooted.
What I can tell you is what I had to do in order to get LTE (voice calls) running on my G7 - I was forced to switch over to LTE because AT&T turned off 3G here in the US and 4G without LTE is not good enough for voice calls:
Get the latest stock firmware and install it using e.g. Lenovo's "Rescue And Smart Assistant". That will get Motorola's Android 10 on the phone.
After installation, go through setup and actually make a call (calling your mailbox is fine). Then check your ims status (*#*#4636#*#*, goto phone info, pull ims status) to see that ims is actually working.
Shutdown the phone and start installing LOS (use the partition copy script too to make sure that the partitions not touched by LOS installation are updated "on the other flash bank").
Go through LOS setup, select a valid APN for your setup, set "LTE only" or "LTE / WCDMA" for the network and make a call. You should be good to go.
Again this is what I had to do to get LTE working with AT&T USA. YMMW.

I know this is way late, and you probably already figured it out. I didn't share the no text problem. The Problem isn't just the "LTE" setting itself. There is one more option(some Roms show it, some don't) I believe its in the phone app settings? VOLTE must be checked. I have noticed Some Roms do have this option and some don't. when volte is checked, it'll keep your data/internet on during a call, some Roms that option won't show up or isn't available. I haven't used G7 in a while, but I do remember the problem and how to fix (on my phone anyway).
