I recently rebooted my phone. Once it came back up, I was unable to connect to my cell network (T-Mobile). I have found the APN setting is missing (Image 1). Using the *#*#4636#*#* and selecting Phone Information (Images 2 & 3) I don't see the phone's IMEI, the GMS Radio shows as OFF and selecting the "Turn Radio On" does nothing. I've tried to change the "Set Preferred Network Type" to LTE/GSM auto (PRL), or anything else for that matter, and after rebooting it is back to LTE/GSM/CDMA auto (PRL). Factory resets haven't worked, with and with out auto restore enabled, even not signing in with my Gmail Account. Removing the SIM and reinstalling does nothing.
Thoughts? Is the GMS Radio fried?
Maybe bad Sim. I have had 3 changed. I was told this phone should stay on cdma, gsm, LTE auto prl. In hidden menu. And global in network settings in android. Have not had a problem since. Fingers crossed.....

Hi I have a problem with the data, it is often as if he lost the connection to the mobile network internet shutting down for a few seconds and then reconnecting after a while. The whasap not send, do not load the pages ... I have to remove and replace the data.
Does anyone know why is this happening?
thanks
What is your APN settings? I had my APN protocol and APN roaming protocol set to IPv4/IPv6 and was having the same issue. I switched it to IPv4 only and haven't had an issue since.

It's a software problem which will hopefully get fixed in 4.2.2 update

I found a little trick. by keying in *#*#4636#*#*
in phone information on the option to change the network type, I replaced wcdma preferred for LTE/GSM/CDMA auto (PRL) and the problem is gone.
Served to me to, I hope you do too

I did that trick, but after rebooting the phone, setting reverts to the original one, "WCDMA preferred". Is there any way to force that setting to be permanently saved?

Restarting the phone is restored to as before, no rebooting.
Is a solution a little bad, but at the moment there is nothing better
Hello dear XDA Community,
I have an american Nexus 6P (used with Verizon) which is currently used with a Russian cell carrier "MegaFon"
I had troubles with connecting to their LTE, for some reason my phone just wouldn't connect to the LTE and only stick to HSPA or HSPA+ even though an iPhone near me gets LTE signal just fine, the SIM card is fine in the other phone as well. So I started messing with my phone to find if I could fix it, first I started with going back to full stock, that didn't help, the phone still only accepted HSPA signal. Then I tried multiple ROMs and Stock Images but the issue of not connecting to LTE persisted. Then I found out about *#*#4636#*#* menu (aka Phone Info menu) and I started messing with it, which again did not do any good until I hit the menu button and pressed Select Radio Band (P.S. please don't mess with those settings) where I tried selecting all 3 different "GSM/UMTS" Bands. I tried USA band, Band mode 6 and Band mode 7, but this just broke down my signal completely, I cannot connect back to the carrier network no matter what I did. I've tried factory resetting, flashing radio img's, flashing stock/custom. NOTHING HAD HELPED/WORKED
I'm now stuck with a phone that doesn't work at all, and I'm on business trip so I'm just pulling out my hair for messing with those settings in the first place.
Does anybody know a possible fix to this? How could I go back to what I had before even though I tried all kinds of forms of factory resetting the phone
I really beg for your guys' help
Thank You
EDIT: Found this http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347 gonna try that right now
EDIT2: That modified ROM helped! But I still don't get 4G
Have you tried removing the SIM card, rebooting the phone, then going into the Phone info menu and setting the preferred network type to LTE/GSM auto (PRL)? Maybe afterr another reboot with the SIM inserted the phone will connect.
Also check the APN settings -- they might have changed.

I think I've tried it, I'll give it another try after seeing if flashing this one ROM where you can select Auto Band in 4636 menu that I linked in the edit would work.
APN settings were fine.
Thanks
EDIT: That ROM helped! But I still don't get 4G
Looks like the post you linked should do the trick. Good luck!
code in Huawei *#*#4636#*#*
I have the same problem. My Huawei is Portuguese and the sms work and the internet to but no signal radio. Wen I dial a number tells me no radio found. Can somebody help me? Thanks
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.
Hi there,
I have encountered a strange problem. I was fiddling with the preferred network services in the *#*#4636#*#* menu. Now, no matter what setting i use, i can't do any outgoing phone calls anymore, neither can i be called by anyone. I tried to set the menu back to the original setting which didnt help.
Restarting the phone, resetting the sim-settings nothing has worked so far. Does anyone have a clue what I should try to be get my telephony service back?
I am on E-Plus / LTE in Germany.
Thanks a lot!
Try to insert the sim-card into the the second slot.

Have you tried downloading the ZTE A2017G software and installing it? Not too sure about the European model but that has saved my butt with the North American model more than a few times
The phone is stuck in "LTE only" mode. It doesn't connect to 3G or 2G networks anymore. And since my provider does not support VoLTE, there is no telephony service for me. I just found that out in a place where there is no 4G connectivity. The question is - how do I get my phone to connect with 3G and 2G networks again? I tried all preferred network settings in the service menu as well as all settings in the sim-card settings. I formatted the cache. No change. I will try your suggestions and see if that helps. I still find it weird, that I am able to set my phone to 4G only but I am unable to set it back to normal. Btw. the phone is stock and unrooted.
Thanks so far!

I re-installed the A2017G Nougat Update, but that didn't change anything. So I downgraded to B10 (6.0.1). The integrated backup process went bad, so I ended in recovery doing a factory reset. From there things started to get better again, the phone finally connected to 3G and 2G networks! So I updated to Nougat and right now I am setting up my phone again, hey but it works!
I want to warn A2017G users to mess around with the info menu *#*#4636#*#*, especially dont touch the "frequency selection" menu. It gave me two choices "United states" and "800 cellular", both seemed to be wrong for me living in Germany, but I had to choose between the two. I suppose that got me into the trouble in the first place. Stay away from that menu. I learned that the hard way.

Hello
The problem i have is for the Dual SIM version (HongKong).
Every tyme the phone is restarted the Prefered network mode is reset back to default mode : GSM/WCDMA auto
The options I have are:
GSM/WCDMA/LTE auto
GSM/WCDMA auto
WCDMA only
GSM only
Has anyone else experienced this and would you know where is the best place to report this to LG?
thank you!
I'm experiencing the same issue when using on T-Mobile. I've even modified my APN settings to match TMO GS8, small change in APN type.
I submitted feedback to LG HK, https://www.lg.com/hk_en/support/contact/chat-email/email
I can confirm this behavior is the same on my H990DS that I'm running on the telus network in Canada. Every time the phone is restarted it always defaults back to "GSM/WCDMA auto" instead of "GSM/WCDMA/LTE auto"
I wrote LG support in canada and they told me they couldn't help me because it's an international phone. And that it was probably a problem with my APN settings (what a pathetic cop out canned response). There is obviously nothing wrong with the APN settings, as it has no problem grabbing an LTE signal when I set the preferred network mode to "GSM/WCDMA/LTE auto"
The issue, is that the phone resets it's preferred network mode to "GSM/WCDMA auto" every restart. As seeing that other people are experiencing this same issue in completely different carriers pretty much says that this is problem with the phone .
Has anyone found a solution?
I have the very same issue, i the past I have used an app that I could force a 1x rtt connection on a cdma phone, the app itself used the advanced phone menu to do this, but a lot of these app don't work anymore and haven't since kitkat, but I don't suppose it'll hurt to try, the one I used for my cdma phone was for the HTC thunderbolt, had a gray or black round icon with a little red lighting bolt.
