Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.

Hi, I recently started having trouble with my gf's phone (Nexus 4 running lollipop 5.0, lte enabled, tmo). It started shortly after I enabled a SIM lock pin on the sim, but not sure if that's the cause or not... The phone started to intermittently drop signal, and would not make calls (it would just appear to be dialing, but you'd hear no ringing and never connect). When I'd restart the phone, I could usually make a call. I tried to fix it by restoring everything the stock image, rechecking the apn, making sure stock radio was installed, etc, but the problem persisted and eventually got to the point that voice calls did not work at all. LTE and data worked to get onto the internet, but once a call was attempted to be made, it'd lose all signal. I discovered eventually that if I switched off lte/4g/3g, and only kept gsm 2g on, I could make a voice call. Next I tried her SIM card in my phone (Note 2 on Android 4.4, t-mobile) and as soon as I put her sim in, my phone started doing the same thing. After switching back to my SIM (that was working just fine, before), now MY phone is stuck with the same problem! (Can only make calls with just 2g enabled). I'm at a total loss. Has anyone experienced anything similar, or do you have possible solutions/ideas on how to fix this?
Flash stock and unroot you'll be fine

I flashed back to stock image a couple of times via wugfresh toolkit, but got the same results each time. I did, however, just fix my note 2 by removing my sim (the one that was previously working), flashing stock via odin (didn't help in recovery), and then replacing the original sim. This leads me to believe that the sim in the n4 is somehow corrupted and once loaded, permanently changes some settings somewhere. (I hope that's the problem, and not the phone). I'll pick up another sim card from tmo tomorrow and try flashing stock again before loading it. Any idea what would cause this? The only thing I did different was set up sim lock on the card, and it seemed to work just fine for a while, till it didn't... Thanks for the help, I'll let you know if the new sim works.
Solved
For anyone who may be having the same problem, here is how I solved it. I picked up a new sim card from t-mobile, flashed a stock rom via toolkit (with the sim card not installed), loaded rom, installed sim, loaded correct apn. Everything works as it should now.
Hi, I'm having a very perplexing issue. For the last few months I have been running cm13 on my phone but recently it decided to not revive/send texts or calls but still got 4g and signal. I hadn't updated the rom or anything so that wasn't the fault. Looking at the sim card info in the setting it says it's in service and everything, but says the "cellular network state: Disconnected". I've reflashed to a touchwiz rom and everything worked fine. So far I've tried different cm roms clean and dirty flashing, flashing just the modem on to the cm roms, restoring from old backup before all this, replacing the sim card. For awhile I though it was the APN settings weren't right, but the cm apn settings matched the TouchWiz ones. I've also tried different unbootlocking methods, didn't help. Worked with an unlocked bootloader running touchwiz. My brother has been running the same phone and rom I was and hasn't had any issues. I'm out of ideas on what's causing this right now, hoping some can help.
Had something similar happen. Try changing the APNS till you get a single
Changing preferred networks might help too
Was on PureNexus 6.0.1 then clean flashed PureNexus 7.0. Somewhere along the way, I lost my ability to connect to Verizon cellular service (phone calls and text) - can connect to LTE data intermittently. Clean flashed again, same result. Clean flashed BenzoRom 7.1 and same issue. Clean flashed back to PN 6.0.1 and still can't connect to cellular service. Tried with and without root and wiped everything except internal data every time I clean flashed. Tried putting SIM card and activating old Nexus 6 which had worked fine in past (did not flash anything new on it from the last time I was using it as my daily driver) and same issue. Can activate old Samsung S4 lying around which works fine for both data and cellular.
Got new SIM cards (from store then another one from online) - same issue. Weird thing is that when I put the nano SIM card into the S4 using a nano to micro SIM card adopter, the S4 works fine.
When I try to make a call from the phone app on the 6p or 6, it says dialing but never connects.
Any ideas? Anyone see anything similar?
Have you flashed the latest bootloader + radio? You can use newer radios with older roms so no need to downgrade if youre gonna use MM
Link
Radio version: 03.75
Bootloader version: 03.62
Tried flashing the news radio and bootloader, same result. Also tried flashing stick 7.0 OTA zip on top of clean for flashed PN 6.0

Hello folks,
Galaxy S4, Play Edition, currently rooted and AOSP 7.1.2 installed.
I rarely used data on this phone and never since I installed the ROM. Lately, I needed the data often and I noticed that I do not get the data on this ROM. I confirmed with the carrier about the APN settings (Airvoice Wireless, att MVNO). The carrier reset data from their end. I tried manual APN entry but none worked.
Searching on the web led to various ideas, like reset network settings, airplane mode on/off etc etc. Tried everything, no change in the status quo. I am at loss on what is the problem. I tried the SIM in my wife's phone (HTC One X, Kitkat) and it worked without any issue.
I could not figure out PDA, CSS but the baseband version is I9505GUEUDNL3, in case if it needs an update.
I checked the thread (https://forum.xda-developers.com/galaxy-s4/general/ref-galaxy-s4-i9505-modems-bootloaders-t3315987) over and over but didn't understand what/how this stuff is worked out.
I am really going nuts and I do not want to pony up for a new phone at this moment.
Any help is appreciated.
Flash back to a stock ROM and check for data connectivity. If everything works, it's a ROM issue rather than being a hardware issue.
The issue seems to be related to the ROM.
I restored to 5.0 (LRX21P.S012.141205) and the data works flawlessly.
