Hi,
I unlocked my MT4g a while back using gfree and now I am going to sell it. I'm on ATT now so I went to test out the MT4G and make sure it is still unlocked but I got weird results. I get a signal with my ATT SIM card and it makes calls fine but it won't connect to data at all. If I look in the network info under settings it says the provider is ATT and the network is EDGE.
I tried turning on/off airplane mode, tried unrooting my phone and flashing a stock image but nothing has made a difference. I also tried my friends T-Mo card and it connects to EDGE and HSPA just fine using that so I'm not sure what's up with it.
I did use EDGE on this phone in the past with my ATT sim card so I have seen it working before, can anyone think of anything that could be stopping it from connecting to the EDGE data now?

Did you check your APN settings? You may need to edit the APN setting for ATT Edge network
I've been tracking and testing a bug where if you activate your N6 on Verizon, then switch the SIM to another carrier (say TMO) to test your phone will not re-connect to VZW when you put the original SIM in. This happens if you change the "Global" setting the LTE (Recommended). After you set that on TMO (or AT&T or...) the options menu only gives you 2G/3G/LTE where when activated on VZ gives you "LTE/3G/1x/Global". The only way to get the phone back on VZ is to factory reset.
Today - I just came back from a trip to Canada where in Global mode the phone roamed on one of their GSM based carriers. I didn't change the roaming mode out of Global (I know better) but when I was back in the US the phone wouldn't go back to VZW - instead went to "Emergency Calls Only" I checked the carrier settings and in the time I was in Canada (2 weeks), the Global option disappeared, leaving only 2G/3G/LTE...and no Verzion. It was done. Factory reset time.
Hope they've spotted this issue in their "intensive" testing process and that's why they are holding up the release. If not..be prepared if you roam globally on the N6 to have a dead radio when you come home and factory reset.--unless there is a service/app settings that can be easily wiped...

I had the same issue (my thread is in the Q&A subforum). Nothing short of a factory reset would fix. Hopefully Google gets on this and fixes it. I travel overseas for work frequently, and the whole point of getting the Nexus 6 was so I could use one phone here and there!
I'm on ATT using a GPS version phone, and I noticed in the "Preferred Network Type" my default setting was on "Global". But it only has choices of "LTE (recommended)", "3G", and "2G". So if I switch to LTE, I have no way of changing back to Global.
Subscribing to thread for a fix.
Can you not change the network type in the *#*#4636#*#* menu to "LTE/GSM/CDMA auto (PRL)"?
I just switched back and forth. Not sure I understand what is going on here.
Edit. Ahhh but you also switched carriers, interesting.
well thats a bit concerning... I'm leaving for taiwan in a couple days and was looking forward to just dropping in a sim over there.
So even with 5.0.1 you cant go back to VZW without a factory reset?
Okay I just got back from a trip to Taiwan. I switched to 2 different carrier Sim cards.
Upon returning to the states, I popped in my Verizon sim card and everything works fine.
Yeah, just do the *#*#4636#*#* and change the network that which you'd like to connect. So for Verizon, you would choose CDMA/LTE in the drop down menu. Once you do that, your network options in the regular settings will change.
Same thing happened to me on a recent trip to Spain. I made a backup before traveling and upon return I flashed the backup to get it to work again in the states.

Has anyone seen any updates on this? Is Google aware of this bug? I'm using my Moto X overseas since I don't want to factory reset my Nexus 6 when I get home. This was the whole point of getting a Nexus 6 in the first place: I could use the same phone here and home with a simple SIM swap!
Has anyone tried
fastboot oem config carrier vzw
to see if that will "jump start" the phone back to Verizon?

That did nothing for me. Tried it earlier this week
Those with the radio issues could try to flash only the radio.img using fastboot. This would let you restore the radio without having to wipe the entire device. Hopefully a fix will come when Verizon officially releases the Nexus 6.
My solution was to pop in an active T-Mobile sim, turn the phone on, and then back off, and then pop in the vzw sim.
That seemed to solve the problem.
Interesting. Wonder why a US GSM carrier would fix the problem, but a foreign GSM carrier causes it. Maybe I'll give that a try next trip (in 2 weeks).
I don't think its the matter of a foreign GSM carrier causing the problem.....
I think the problem is Verizon.
I don't hear of this issue with anyone else but Verizon customers.
I doubt it, since the inability to switch modes is present even before the Verizon SIM is inserted. I think it's a bug within Android itself.

I just tried this exact same thing after being in London and Budapest. My Verizon SIM in my Nexus 6 wouldn't register on their network. I put in the T-Mobile SIM and it did work and register with no problems. Switched back to Verizon's SIM and no luck. Still not able to register on the Verizon network.
To clarify, the verizon sim roamed onto canadian providers without problems. When I returned to a normal Verizon service area, the phone wouldn't register again (on verizon) until I popped in a t-mobile sim, and then switched back to the Verizon sim.

Yes, that's what I did. Went to London/Budapest with the Verizon SIM roaming. Landed back in the States, no more Verizon connection on the Verizon SIM. Popped in the T-Mobile SIM and it works perfectly.
Tried doing the switch back like you mentioned, but no luck at first. Had to try a few times. Back to life now.
Thanks very much.
I just "upgraded" to Android 7.0 today. My carrier is Verizon.
I'm not sure what's up with it or how to troubleshoot it, however I need my phone back up as soon as possible.
Any help would be greatly appreciated! This is kind of a big deal for me.
Under Dual Sim Settings->Network mode it says the following:
Card 1: LTE/WCDMA/GSM
Card 2: missing or error
However, it's not connected to Verizon's network at all.
I've tried popping the sim in and out, along with restarting the device.

A SOLUTION HAS BEEN FOUND

I managed to get a hold of a friend's active AT&T phone. Put his sim into slot 1, rebooted and put the Verizon sim back into slot 1 once the AT&T sim was recognized.
This resolved my issue. I just did it so I don't know if it's a permanent fix or not.

I had to remove both my SIMs, put my GSM (T-Mobile) SIM in slot 1...wait for the phone to recognize the SIM...then reboot a few times...then turn it off...put my Verizon and T-Mobile SIMs in slot 1 and 2 respectively...and then reboot. It's worked fine ever since. An old, inactive GSM SIM or a friend's will work fine for this procedure.
But yeah lots of people are having this issue with Verizon SIMs after the update. Really annoying...but it does seem fixable in most cases.

Thanks, I have a friend with a GSM sim. I'll try this out tomorrow night.
@flyer_andy has helped me too with this problem. I had to buy a straight talk sim from Walmart for $50 to get this thing working. I had to do it because i updated on the way to work. Once got to work i had no phone :crying: lol
I had to use my sisters sim card. I turned off the phone, put hers in, once it saw T-Mobile, I took the SIM out while the phone was on, swapped and was good to go. Boots just fine with Verizon data.

Just had a similar issue, running dual SIM. My T Mobile SIM which I use for the mobile data lost its data connection and would not reconnect, showed full Signal but no data. I eventually had to swap the 1 and 2 positions and now it is working.

I hope a phone came with it for that price.
I picked up a SimpleMobile (T-Mobile MVNO) SIM at Family Dollar for $1.
I also had the unexplained automatic reboots after installing B15 last night. It also wasn't recognizing the SIM. It wasn't even recognizing the GSM SIM. I did a couple factory resets and reboots with the GSM installed. I t looks like it needed the radio reset like back in the old A20 days. It eventually recognized the GSM SIM. I then switched out the PagePlus SIM, and added the Tracfone APN.
Everything I looked at seems to be working. Speedtest is showing 5.46 mbps down, but only 100 kpbs up. I think that's about normal for me.

I wrote too soon. I'm back to no service. I'm not sure when service disappeared
I tried putting in the GSM SIM and rebooting a few times.
I put my PagePlus SIM in my old Galaxy S4 to try to have that recognized on the network.
I powered off the Axon and replaced the SIM with the PagePlus one.
It starts up and shows No SIM card, then No Service, then Verizon Wireless for a few seconds, then back to No Service.
It looks like the problem I had when going to A29, but the solution to fix it then isn't working.
Edit:
I did a factory reset with the PagePlus SIM inserted. It came up with phone service. I had to add the TRACFONE.VZWENTP APN.
It then showed an LTE connection. I shut off Wifi, and it started to load a web page. It then stopped loading, and went back to No Service at the top.

Do you have a Verizon phone that you can stick your PP SIM into, to verify that the SIM correctly works?
i'm having similar data connectivity issues with my Axon 7 and at&t after the Nougat update. Axon 7 is rooted with B15, using 1-sim and a microSD, here's my issue description
-
day 1-3: 4G/LTE connection working, no data issues
day 3: 4G/LTE connection working, can connect to web pages, but could not connect to Google Play, Youtube,Google News and none of my 3 Exchange email accounts. Switch to Wifi and no issues connecting to any Google Play, Youtube,Google News and none of my 3 Exchange email accounts
day 4: Same issues as day 3, factory reset manually reinstall all apps, email accounts, etc. after a couple of reboots, could not connect to Google Play, Youtube,Google News and none of my 3 Exchange email accounts. tried Lineage OS and 4 hours after fully setup, problem is back. with Lineage OS, signal bars showed no signal with each connection attempt and after 30 seconds, connection timed out and signal bars would return.
Troubleshooting:
- swapped sims from two working devices into the Axon 7 and same no-connection/time-out connectivity issues with Google Play, Youtube,Google News and my 3 Exchange email accounts
- all 3 sims tested work in every device except the Axon 7
- at&t re-provisioned my account and confirmed there are not issues on their end.
i'm stumped. any suggestions would be appreciated. otherwise, i'm in my 14-day window and my have to return the device. thanks.
When the verizon sim is installed, is global mode an option under settings, network settings (not the 4636 menu)? If so, try that.

I should have been clearer. The PP SIM works fine with my old Galaxy S4. I miss a lot of incoming calls with it, but that isn't configuration related. It's always done that.
Thank you for the reply.
Can't recognize ATT sim either..
Pull the sim and factory reset, reset network settings also. Then put the sim in and keep factory resetting until it's recognized. Took 3 tries on my phone and 5 on my friends.

Are you all able to use HD Voice & video calling with the native dialer on the Verizon network? Some phones have an option under settings called 'Advanced Calling'. This is where you can turn on HD Voice & Video Calling for Verizon.
Hi guys,
I bought the unlocked firmware phone back in December 2016. The phone is great, the problem is I am using EcoMobile MVNO. It's refusing to recognize the network with the MVNO's sim card. I've spent hours on the phone with them and they claim all is OK on their (and Verizon's) end.
The phone sort of works, so I've just been grinning and bearing it so far. Using 4G switcher, I can put it in CDMA only mode, in which case it connects to '123456' and I can receive and make calls, and receive texts, but have no internet. If I put it in full LTE/GSM/CDMA auto mode, it connects to LTE, so I have internet, but it claims I'm not connected to Verizon network and in fact it's not available. So in this mode I can't receive calls or texts. Can't send texts under any mode. I've done a full factory reset at the MVNO's behest, of course that did nothing. The phone seems to connect fine to Verizon's network if I borrow someone elses's Verizon sim. My MVNO sim also works in my wife's iPhone5 without a problem. So it really seems to come down to the firmware on the phone. I'm holding out against hope that when Nougat comes to the G935U firmware, this problem is magically solved... but just in case decided to post here.
Please help, any ideas would be appreciated.

Flash the vzw firmware or go through the steps for the hybrid rom with vzw modems implemented.
Thanks. I was really hoping for something less intrusive, maybe some CSC edit fix, or some such.

Welp, the 7.0 update is here, and it didn't fix my issue, in fact now I can't even get LTE data as I used to get. :crying:
So I had this issue when I first got the nougat update. When I got my S7 I put in my brothers sim card to made sure it worked on Verizon cause i was buying it from someome and anyway I activated my straight talk verizon SIM and everything was great until I got the update and my service was weird and I didn't know what to do and then it dawned on me, I put in an actual verizon SIM card, doesn't need to be active let it register and then put your SIM back in and everything was great! Hope this helps...
Switched to TotalWireless, phone works now. They first sent me a SIM which didn't work, then had to send a different, post-paid one.
I now suspect if ECO also sent me a postpaid based SIM it would start working. Things are always way too complicated when Verizon is involved.

I'm tempted to try this as I'm having the same problem with my 935U and Xfinity Mobile (Verizon MVNO) SIM, instead of connecting to the Verizon network, it connects to network 123456. I did load the 935V firmware, which worked fine, but I'd prefer to return to the U firmware if this would work. Is this still working for you, and if so, do you just need to put the regular verizon sim in once and from then on the MVNO sim will work, and continue to work including after a reboot?

I put in a Verizon SIM in it once and that was after the nougat update. But every time the phone restarts, I have to make a phone call for it to connect to the service or it will just stay stuck in "searching for service" but once the phone call connects, I hang up and everything works as it should.

Thanks, strange problem. I'll probably just stick with the 935V firmware for now as that's working fine (just have the Verizon bloat and failing the hotspot check). I also have a dialog going with Samsung support to see if they're aware of the problem and have a fix.
I used prepaid T-Mobile from the first day that I had this phone and never had an issue with VoLTE. I decided to switch to AT&T prepaid for a month to try it out, and it wasn't very good in my area, so I decided to switch back. AT&T prepaid doesn't have the specific feature where LTE data service remains while on a voice call (I'm drawing a blank on what this is called at the moment), so I wasn't surprised when on AT&T's network that the phone would drop back to 2G for data service while on a voice call. However, after switching back to T-Mobile, the phone is still falling back to 2G while on voice calls. My girlfriend also has an S8 on T-Mobile and so I can verify that we can be on Band 12 and she can place a call and remain with LTE data while I fall back to 2G.
As for troubleshooting that I have done so far... The software did update when I put my T-Mobile SIMcard in and I verified the APN settings and that VoLTE is enabled. I also did a factory reset with the SIM card in the phone and it still did not work. At this point, I'm just looking for suggestions on what I could try next. I don't understand how a factory reset could have not fixed this. Any input from those knowledgeable about how the software updates for specific carriers modify the phone would be helpful. Thanks for the help.
Bump... Anyone have any ideas of what's I could try next?
