The mobile network just shut off for some reason.
I'm fairly inclined with tech, so scanned through the usual network settings and the apn network options, multiple reboots, clearing cache still nothing.
I am definitely in good standing with my mobile carrier, so I don't think its a carrier side thing.
Anyone have a similar issue?

Here is a link with a screenshot of what the network icon looks like: http://imgur.com/a/wIZpg
I'm using a Galaxy View LTE with no SIM inserted and that's the icon that's shown. Can you place emergency calls? If so your phone sees your SIM. If not that means your phone doesn't see your SIM and I can't offer any help as to why.
Do a factory reset and try again. OR change your SIM.
I had a similar problem. Go into settings>Connections>More connection settings. At the bottom go to Wi-Fi calling. Check to see if Never use Cellular is checked. It was on mine. Don't know how or why. It just was.

Hello all,
I have resorted to posting here as i have trawled the web for a solution without any luck. Here is my problem hope you can help.
I have a nexus 4 and am currently in Spain. After traveling abroad and not using data roaming i came back to Spain to no mobile data connection. The usual tricks of restarting, toggling mobile data airplane mode didn't work. It was quite frustrating. I went as far as to cancel my contract and go for a prepaid card - Lebara as they have a decent data tariff - but the problem persisted. I have configured the APN, gone through all the restart procedures, even factory reset the phone twice and nothing helped.
Mobile data is switched on. I have the APN set up as needed. However, the H E H+ never appear next to the bars on top no matter what i do. I have ordered another SIM card from a different operator in desperation but it might not be here for another week.
I really hope it is not the phone but now I really don't know. I am taking suggestions...
Thanks
PS one thing I just noticed is that if I download apps from my browser the device is listed as vodafone nexus 4 although I have never been on vodafone. This might have some relevance

Go to the dialer, press*#*#4636#*#* this brings you into new menu. go to the phone information to see to what network you are connected. if you scroll down you can force the phone to use 3g (WCDMA only) see if this work. this seting will change when the phone goes into reboot.
also if you happen to have the "3g bug" connecting to a wlan might help as stated by some users.
For me starting the hot spot function does the trick.

Thanks for the advice endet. I have done this but to no avail. When I switch to WCDMA only in the field GPRS service it says connecting for about a minute and then disconnected. After restart it is directly disconnected. I have toggled between GSM only and WCDMA only and restarted the radio. Played with the other settings in this screen and nothing. Only once did I get brief flash of the H on top but trying to replicate the steps didn't lead to anything.
Starting tethering didn't help either...
Could be something with my IMEI? Or CellInfoListRate?
I got an international version SM-G900i from Amazon. I have an ATT sim card. The text and phone calls work fine but I could not get any data roaming. Though from other posts I got the data roaming, I was not able to set onto the ATT 3G/2G network in the network operator selection. My network is always shown as Maritime. Does anybody know why this happens and ways to change it?
Thanks a lot.

I tried configure the APN setting based on a link online for ATT APN. Now I am losing signals even for calls and texts....I think there might be other things that are wrong...
Error message for no ATT service
Tried different variety of ATT APN setting. Still could not get it to work....the phone shows a signal but gave me an error message that Selected network(AT&T) not available

I'm not sure what did you mean by "data roaming"??
Anyway, the problem for now is no network register. The APN settings will NOT affect at this step, so not not try to mess up with it right now.
Try to get into Settings > More networks > Mobile networks, and set Network mode to Auto connect, and Network operator > Select automatically.
That may help the device to register on the Home network.
Problem solved....or maybe not but it is working!

Okay. Thanks. I switched it back to the auto-selection mode. By data roaming....I mean 3G data. My phone is working now. I checked ATT billing usage report, it did not increase the data usage dramatically so I guess everything is fine.

Glad that your phone works now.
BTW "data roaming" and "3G data" are different things. "data roaming" is "3G data" when you are roaming to another network (not your home network).
At work on Friday I was trying to do anything but work. So, I took the sim out of my work iPhone and put it in my 6P. After booting I noticed it wouldnt connect to 4G/LTE, didn't think much of it. Turned off, the put correct sims back in phones. iPhone boots with LTE connection with work sim, 6P boots with 3G connection with personal sim. Hm.
I tried toggling Airplane mode, data on/off. Tried various 'LTE OnOff' apps. Dialed *#*#4636#*#*, reset APN to default, cleared cache in Storage menu. Wait until I get home, flash latest Android M image (except userdata). No changes after boot, still only connecting to 3G.
Now I've flashed Jan/Feb/March images, no luck on any. Tried Android N, still 3G only...
When I put my personal sim into my Moto X, I have LTE connection and speeds.
Looking for help???

I thought I remember my phone originally being in 'Global' mode
Anyways, my choices are
Global
LTE/CDMA
LTE/GSM/UMTS
I dont have an LTE Only option. I switched to LTE/CDMA, restart. No change. Same when choosing LTE/GSM/UMTS.
Toggle Airplane mode to kick it back to LTE. I've tried a few fixes including changing APN Type but that hasn't fixed it, still happens.
EDIT: Skimmed over the part where you said you tried it, sorry. Try changing the APN type to "default, admin,mms,supl,fota,hipri,dun" in that order.

I tried your APN settings and the settings from this site (https://apn.gishan.net/settings/1259_13_verizon_apn_settings_for_huawei_nexus_6p.php)...no luck
Using the same sim card (my personal one that previously worked in the 6P).....
The *#*#4636#*#* menu is showing Network Type: EvDo-rev.A on the 6P and LTE on Moto X
Speedtest on 6P shows - D:2.61 Mbps U: 1.13Mbps
Speed test on Moto x- D43.62Mbps U:20.37Mbps
Speed test on iPhone - D: 34.99 U:18.74
This tells me it's not a sim card issue but something changed on my 6P
Took it one step further, went all the way back to stock, wipe userdata, fastboot flashing lock. Reboot, still 3G.

I'm having the same problem with 6P on t-mobile since last week when I applied April update.
T-mobile say there are no issues with local cell towers, Google pointing finger at t-mobile
saying: " appears that the phone is receiving a signal that is switching the cellular data to Edge which is an older technology. It is possible that your device is receiving a signal from an older tower. Older towers do not work well with newer multi-band devices and this could be causing the issue".
I'm talking to t-mobile again to confirm they've not got any issues, but given the timing and given the fact that I see this on all the local towers I'm more suspicious about the phone/software, but we'll see.
I've tried factory reset, replacement sim reflashing a few different versions of stock rom.
I'm currently (slowly) working my through the logs in the bug report. It's slow going but interesting reading.
Do you remember what versions of the radio rom you've tried?

Dial *#*#4636#*#* and click the 3 dot menu on top right and choose band 6. Its possible that it got changed. Under preferred network type make sure its set to LTE/gsm/CDMA auto prl.

I have that network type selected. When i select a different band, should i expect something to happen? Do I need to restart?
Got a new sim card yesterday as well, no difference.
Looks like I may have fixed it!
Did not work:
-flashing images for MMB29P, MHC19I, MHC19Q, NPC91K (DP2 ANDROID N)
-New sim
-Messing with APNs, toggling airplane mode, selecting different bands in *#*#4636#*#* menu
I knew when I originally rec'd the phone, everything worked. So I figured, why not try the original original images?
Solution: Go back to stock! Flashed MDA89D and my LTE is back.
-As soon as it booted, I made test calls/texts. *#*#4636#*#* shows Network Type: LTE and Preferred Network Type: LTE/GSM/CDMA auto (PRL)
-APN page lists 6 APNs (it wasnt doing this when I only had 3G) and selected by default is VZWINTERNET
-Update to 6.0.1 immediately popped up as well. LTE still active after update! (This takes you to the December Security update. Then you go month-by-month to most recent)
My problem is obviously different as I'm on t-mobile but f.y.i.
I flashed October's image (MDB08K) which is an image that doesn't support the newer LTE bands (eg 12) and now I have LTE again.
just got the phone yesterday and updated it to the P beta. everything works amazingly well for a beta in my opinion, BUT i cant receive calls. outgoing calls, texts, web and apps are just fine.
spent almost 2 hours at tmobile flipping all the settings around and no luck. any ideas would be appreciated.
Same issue here bro...Incoming don't ring but I get voicemail notifications.... Really annoying, even if it is a DP.
Turns out the beta doesn't play well with the essential LTE. Switch to 3g and calls will come through. Hopefully it doesn't take long to find a work around for it
I believe the people having this issue have volte enabled...try and disable volte (it's broken anyway and more than likely why calls won't ring through) and see if that works
Got same issue... My experience was that I could solve the problem with reboot.
Issue came after playing on settings for mobile network.
Is meaning, when you do this you have to reboot afterwards otherwise you can't receive calls
Try it.

Tried rebooting multiple times while changing settings around. The only way I can get the calls to come through is by going without LTE completely.

Settings/network settings/mobile network/advanced/enhanced LTE?
I had the same issue and to fix mine I just enabled Wifi Calling.
When on wifi I didn't get a call, just missed call notification. After enabling wifi calling, it comes through without issue.
I tested calling off wifi and on wifi and all calls come through good now.
This could be similar, so you guys might want to look at that also.
Good luck!
Heard from a few that this was solved by going into phone app settings -> calls -> calling accounts, then turning on "receive incoming calls". Seems it's disabled to save battery? Can't confirm as I just flashed to try it out and then went back to 8.1 because I like themes too much. Lol.
I'm on Sprint and was never able to make or receive calls regardless of Network settings in the easily accessible options menu.
The following fixed my issue. You can access this menu without downloading an app but I forget how so it's easier to just download the free app https://play.google.com/store/apps/details?id=com.xsquarestudio.forcelte
I had my network mode set to LTE/CDMA when first using this app, and somewhere in the middle I changed it to CDMA but I'm not sure how much that impacted the actual fix.
These were my steps. I'm not responsible for any damage this may cause to your device as I'm not sure if messing with these settings is foolproof or not.
First, opened previously linked app "Force LTE" then under "Set Preferred Network Type" I changed to CDMA only. Enabled/disabled airplane mode. This seemed to do nothing as LTE was still showing in statusbar.
I then chose CDMA auto (PRL), airplane mode on/off, didn't seem to do much either. LTE still showed in statusbar and couldn't make calls. Also "Voice Network Type" showed "Emergency Calls only" inside the app.
I then chose the 3 dot menu and chose "select radio band". I changed that to United States, without resolving problem. Then selected "Cellular 800" and this may have solved the problem, but I continued on and selected PCS, fiddled with some settings in Phones settings menu. Was finally able to receive calls and my signal indicator showed 3G. In app Voice Network Type was listed as 1xRtt. I decided to select radio band once more and chose Class 10.
Calls were still functioning fine. So I went into Main settings menu and changed mobile network from CDMA to LTE/CDMA. LTE kicked in and calls still work!
Again, these settings may only work for Sprint hence the PCS Network option, and I believe Sprint may utilize the 800mhz frequency. The app might show you different options depending on your carrier. I don't know.
Anyway, fully functioning! Woohoo!!

I don't have anything in my settings that says "enhanced LTE" .
Tried using the 4g/LTE and the LTE only options. Neither would let calls through.
I have this problem using the Essential PH-1 with Android 9 Pie in South Korea on the KT network. It should be fully compatible, according to radio specifications, however it only works when I change the following setting:
Settings | Network & Internet | Mobile network | Advanced | Preferred network type | 3G
This is not ideal, since it makes the Internet slow, but at least I can make/receive voice calls. I submitted a support ticket to Essential requesting their official help (I'm well within warranty).
I had the same issue when I use my Att prepaid plan. The problem is caused by wrong network type, you can send text and browse internet, because they use the different channel. My PH-1 wrongly recognized the sim as CDMA/LTE mode, just switch it to 4G/LTE, it will be work. Go to Settings, then search "wi-fi calling", point "advanced" then you can see an opinion "Preferred network type" if you are ATT or T-mobile user, and your preferred network type is "LTE/CDMA“ then your phone cannot make call. Switch it to "4G/LTE", you phone will be work. BTW, Verzion uses CDMA, so if you are Verzion user, CDMA/LTE will work for you phone.
Problem background: I was having problems when phone was getting stuck at WCDMA (found out using network cell info app), losing sms and calls function, and not switching to other network types, requiring a restart or a toggle of the 2nd sim to off and on (I had my sim 2 off most of the time).
Solution: enter *#*#4636#*#* in the phone dialer, phone information, set preferred network type, NR/LTE/TDSCDMA/GSM.
Phone will not connect to WCDMA but for me, this is the better option since LTE signals are stronger in my area.
One benefit was also an improvement to my battery life, I guess because phone will not search for the weaker WCDMA signal anymore.
I hope you find this useful and you also resolve your problem.

Sounds to be connectivity. They should have gave you a new sim, unplug modem, repulug modem. Clear cache, reset phone, this looks for best tower signal. Make sure your on the latest update. These are basic troubleshooting. If nothing call one plus technical support number. They will ask if you've done these steps. They talk you through More steps. Get it fixed!! Do not Hard reset unless instructed to. Get back.

Pretty sure this is not a sim or network problem. used the same sim on an iphone and samsung and never had this issue.
I had signal issues a found turning off smart 5g in settings yielded better LTE and 5g connection there is a reddit post about it even maybe try it if you haven't already worked for me and my device is 8t global on T-Mobile by the way.
