Galaxy note 2 (N7100) unable to connect to mobile network

Hi
I bought my galaxy note II 3 days ago, first day it worked fine, in second day the service was lost.
I tried connect to mobile network by Settings/Mobile networks/Network operators
it finding mobile networks but not connecting to him. its wrote "unable to connect, try later"
I changed sim card with another carrier and It's the same thing.
I did Factory data reset, and it still not connected to mobile network.
What can i do? help please.

I had the same kind of issue when I first got my note 2.
I had to wait for my provider to send me a message with the Internet and mms settings for my phone to connect.
Try the "my services" the app in your drawer and get Internet settings from my account. Or you could try calling your provider and getting then to send you the message to install it.

But, the problem that my device not connected to mobile network, so cannot receive data.

I was sent a configuration message via text message which installed the items required.
Sent from my GT-N7100 using xda app-developers app

Cannot send and receive message and cannot call. So the problem not in mobile network configuration, the problem is that device cannot connect to any mobile network.
I bought the note from England, and I am in another country. What can I do with warranty?
No one more than not having a problem?

Yes, it shows a 15-digit IMEI number.

Does your network mode set to 'Auto', if not do that. and still doesn't work then try GSM only
Setting - wireless n Network - mobile network - Network mode.
If you have selected WCDMA and you are not in 3G coverage it can happen.

Not connecting in "Auto" and "GSM only" mode.

Where did you bought your phone?
Sometimes someone sells phone and then report it as stolen, and imei is blocked by network operators.

My issue started once i let WanamLite update the modem. Before that all was fine and dandy.
I tried flashing several stock roms and several modems, no luck.
I also tried a N7105 Rom, no luck either.
People suggest its an EFS issue, reading a bit on that before I do this:

Same here. I bought it new from an authorized dealer. I hate it when I have to bring the the device back to the dealer.

I Found a solution
Hey guys! I'm experiensed with flashing of roms and that king of badass stuff and flashed a sugersonic hd rom yesterday, later on the calling and messaging stuff didn't work and i couldn't connect to the network, then i flashed criskelorom, and now everything is perfect again!
If you are not experiensed with these kind off stuff do research before attempting!

[Q] Verizon HTC ONE can't add new APN

hi, I have verizon htc one running on stock 4.4.3, sense 6.0. I want to use it in europe on gsm network, voice and text works perfectly, but I can not use data because I can't add new APN. there is not options to add new one in access point names. when press on three dots just comes up "reset to default". so what should I do now?

I would call vzw to unlock your SIM, then plug in a prepaid SIM from a local European carrier.

found, I should enter mcc mnc codes, thanks

I have this same issue. I was already overseas, and couldn't add or edit the APN I needed to use for O2.
I've called Verizon multiple times and they say "it's already unlocked" over and over again.
Is there anybody out there with a Verizon HTC One and is able to edit the APN data? If so, what did you do to get the phone to allow you to do that?

same here. using a Verizon HTC One (M7) on Rogers network in Canada. i cannot edit the existing APN or add a new one at all. i am connected to the internet, but it shows an 'E' instead of '4G', and it's very slow. any work arounds?
also, when i try changing Network Preferences and adding Rogers' MNC, (302720), it tells me my Network Preferences list is full and won't save anything when, in fact, it's actually completely empty! any ideas?

Does Rogers use LTE band 13? If not, you will not get 4G. As for HSPA/3G for GSM, the phone only has 900 and 2100 mhz for it. So if your carrier doesn't support those frequencies, you are stuck on edge (E).
http://www.htc.com/us/smartphones/htc-one-m7/
Specs tab shows the frequencies I discussed that the phone can support.
Edit: I also put this info on our Q&A thread.
[SIZE=+1]Q2: can I SIM unlock this phone for other carriers?[/SIZE]
The m7wlv comes SIM unlocked out of the box. It only works on certain frequencies. See if your carrier supports the below frequencies.
CDMA: 800/1900MHZ,
UMTS/HSPA: 900/2100MHz,
GSM/GPRS/EDGE: 850/900/1800/1900MHz,
LTE: 700MHz (Band 13)(only Verizon uses this LTE band thus far)​

Did you go to network preferences and click add....then click operator list. Scroll down the monster list and add Rogers wireless? Once you add it you need to reboot for the apns to autopopulate. With the new way of doing it they autopopulate.

Screenshot?

here (as you can see, the list is empty, but it's telling me that it's full!):
and when i add Rogers Wireless by entering the MCC / MNC manually, i'll get this:
and going back to the previous page gives this message:
also, i cannot edit or add any APNs at all.
i'm sure it's the phone. is it SIM locked? (it shouldn't be given that it's from Verizon, but i got it as a replacement from Verizon because my first one had a faulty GPS, and it was refurbished.)
any ideas?

When you click add.. don't click add network code. Click operator list.

i didn't click on anything. that's the window that pops up when i go t Network Preferences List. i cannot do anything else.
i really think it's a phone software issue (the same phone, using a Verizon SIM card, was able to connect to Rogers' 3G network while roaming)...something must have messed up the software. funny thing is that with the Verizon SIM card, i could look at the operator list and add/edit the APN and all that.
is there any way, short of a factory reset, to revert the settings back? could it be that the phone is really SIM locked?

Having the exact same problem
I'm having the exact same problems as those described above... I am on a fully stock Verizon M7 with the latest official release. Not rooted.
- cannot add new apn.... Option missing from he apn menu
- when i attempt to edit the existing apn, all i can do is edit one line... The apn itself. All other lines are grey and will not allow me to change the settings.
- with a non Verizon sim in the phone i was also having the " network list full" errors described above...
I was in Europe with Lebara mobile sim and was able to get on 3g but it was unstable as apn settings were incorrect and not editable. I was in the UK on a 3 mobile sim and all was the same. Now back in the US, the same problems above with apn add/edit are still there though my "available networks" settings are behaving normally with the Verizon sim in there.
IT must be something wacky with this build or Sense 6 as my GF is also on Verizon and her Razr Maxx had none of the above problems as she travelled with me with the same carrier sim cards as i was using.

yeah, it's very annoying. maybe we should contact Verizon to figure out what's going on.

Exact same problem - no option to add APN or add network

I have an HTC One with the exact same problem. It won't let me put in the proper settings to activate mobile data on the Mexican Telcel network. It was a Verizon phone which is unlocked and will do voice and text but since the APN settings are not allowed to be edited it is not data capable. I'm in Mexico for a few months and this is ridiculous. According to Verizon "of course your phone is unlocked. We haven't sold locked phones in years." I guess they aren't locked now they are disabled or crippled when you try to take them to other networks. BTW this isn't just a problem of us not knowing how to input APNs, this is the problem of the phone not allowing editing at all. Very, very frustrating. Especially when you find out that root is almost impossible when it has the latest over the air update.

Factory Reset Doex Not Fix This
Confirming that factory reset does not fix this. So don't waste your time... Ih yeah, and HTC backup and restore service is down until further notice... Another fun surprise

Maybe I'm wrong but I thought you needed to be boot loader unlocked and s off to edit the apn and mcc list since they are system level files. You need read/write ability for the system in order to do that which requires root.

nevermind

^ what does this "nevermind" refer to?

[Q] Can't add or edit APN settings...HELP!!!

Ok so the APN settings on my phone appear to be locked or something. The only option I have is to restore to default. I can not add or edit apn settings! I have tried different ROMs and some other tweaks I have read and nothing will fix this!
Can anyone help me? I mean is this a Verizon security measure that can not be undone or can it be undone? I'm about ready to get rid of the phone at this point!

You don't edit them anymore. You need to go to mobile networks- network preferences and hit the three dot menu button. Click add and then operator list. You then add the carrier you want from the list. Then reboot and the apn for your new carrier will be there. They made it so all apns are loaded and known by the phone. You just have to select the right operator. They don't want people manually editing apns when you shouldn't have to in the first place.

So what operator should I put in for Straight Talk??? At&t or do they have a ST one?

^ that doesn't work on my Verizon HTC One M7. i can't add any network operator. Verizon has certainly fine something to this phone. there was another thread earlier with a lot of people having the same problem.

Do you have a SIM card in the phone right now? I have a non activated vzw SIM in mine. If I take it out I get no options. May need to have a used/New vzw SIM in there to get it switched if the straight talk SIM doesn't give you any options.

I would bet if you guys got a vzw sim in there you could add your network and put your SIM in later.

Well I have the same problem trying to get apn for Mobistar network in Belgium. For reference, this is using a SIM card that has worked in the past with earlier version when manual "add apn" option was still available.
When the mobistar sim is in, I have the same problem reported before. Preferred network list is empty -- but gives me a message that it is full (!) and when trying to add network manually I get a message telling me it's full and it does not stick. I would have to assume the "feature" is sim card related and not available on that sim card. Hence the "list is full message"...
When I put the Verizon sim card back in, I get the preferred network list OK. I can add the mobistar network to the list. However when I put the mobistar sim card back in still no luck. I still have the wrong APN. Also preferred network list is back to blank. Again the list seems to be stored on the sim card, so bottom line is whitout a sim card with that feature I don't see how it would work. I will have to test this with a new sim card from Mobistar, although probably not this time (I am only here for a week for business meetings).
Also for what it's worth, with the verizon sim in, the new network added to the list does not stick when I reboot the phone.
Bottom line: <sarcasm>one on Verizon's usual great improvement</sarcasm>. If it's working, break it, right?

Actually I think Verizon just doesn't want people to use their devices on other networks. Especially since they have a contract with Vodafone to handle global capabilities. I'm surprised you guys having APN issues don't use a gsm phone instead. They are much more user friendly on other networks.

Well you might give them too much credit for breaking things on purpose instead of by accident. It is worth nothing it only occurs in 4.4.3; I had a nandroid backup with 4.4.2 and went back to that since I remembered it was working fine before. I can confirm there is no problem adding the apn in 4.4.2.
Yes it is strange to use gsm with Verizon but I actually find Verizon world phones to be quite good (until this recent apn issue). The global capabilities work fine and can save you in a pinch (but not good for extended stays due to cost). Or more likely I am too lazy to change carrier...

After doing some googling it would appear this issue also affects the m8 since 4.4.3. Most likely it is an issue from HTC not Verizon.

From what I can remember, all I could do is put it to the top of the list -- not sure what other selection there is. But then when I rebooted it was gone from the list. It doesn't seem to stick. I am now back on 4.4.2 so unfortunately I can't investigate any longer. But I have a working internet connection...
Hopefully the add apn setting was removed by mistake in 4.4.3 and will be back in the next release. For now the word should be that those that need the feature should stick to 4.4.2 if they can.

yes, the APN settings don't want to stick after the reboot. i put my Verizon SIM in, changed the network settings, turned the phone off, put Rogers SIM in, turned the phone on, and puff, nothing is there.
is there a way to put 4.4.2 on the phone? mine is completely stock.

Have you s-off'd? If not, use sunshine to get s-off and downgrading will then be an option.

no, the phone is completely stock. from what i've read here, sunshine is the only method, am i right? i will use it either to install stock 4.4.2 or to install other ROMS, but i haven't done anything of that sort yet (i've bootloader-unlocked, through HTCDev, my other phone HTC One S, and i've rooted it, but that's all i've done). is being S-OFF the only requirement for installing another ROM?

N910V No signal in Argentina

Hello everyone,
I bought a Unlocked Note 4 from Verizon in USA. In Argentina I don't have signal. We use GSM so it should work right. I know this device has not root access. I just want to make some calls or messages.
It doesn't let me search network manually. It throws an error "error searching networks"
Android Version: 4.4.4
Network Mode: Global/GSM
Somebody could help me on this.
Thanks in advance.

I am in Europe past month, leaving to us in few days and was using my note4 in GSM mode all the time and switching between carriers on a prepaid sim. I would do factory reset or maybe get a new sim.
My prepaid sim allows roaming on all carriers.

I already flash the mobile with Odin thinking that the Android version might be the problem. It still not getting signal. I'll try with another SIM card.
Did you use others GSM carriers instead of T-Mobile?

I tried with many SIMs, I flashed the device three times and I still having. So maybe there is a another issue. Please someone can help me. How is the Micro SIM should I use?

Which carrier are you using this on? Verizon has always used CDMA for 3G, not GSM. The Verizon Note 4 (SM-N910V) does seem to have limited GSM support, but it might not work on every GSM carrier.
This website seems to be pretty accurate: http://www.willmyphonework.net/

Acording to that page my phone should work perfectly
with 2G, 3G, 4G LTE.
I'm using:
Brand: Samsung
Model: SM-N910V
Country:Argentina
Carrier:Claro Argentina
I don't know what is the problem.:crying:

You may need to add new APN settings before it will work.
On mine, the option to add a new APN is disabled, but I'm actually using mine on Verizon with a Verizon SIM card, so I'd have no reason to edit the APN settings manually. Are you able to edit yours?

I already set the APN and nothing happens. I'm not sure APN could be the problem. Should be something else.

If the APN settings aren't correct, it could absolutely be the problem. It's worth double checking.

APNs
I tried with severals APN and nothing happens.

I have an Oneplus One with the same APN and works perfectly. That's why I think the APNs are not causing the problems of signal. I still having no signal. I cant make neither a call nor send a message.

Hmm sorry bro not sure what is going on.. last thing I could suggest if you have some money to spare try any other sim card from different provider or ask a friend to swap it for a minute or two,anything to test that it's not your carrier somehow not wanting to work with VZW N4.

I think this phone has the bands blocked. I do not know how to check this.

Hey I read something couple days ago and forgot to get back at you.. I read somewhere if you block activation agent it should work some people on T-Mobile USA had the same issue. Use debloater to block activation agent on boot. They said this could be because the note could never been activated on Verizon even for 30 seconds and this is why it might be happening.
So block activation agent,and setup wizard so it's blocked on EACH BOOT.
Let me know

I do not have any dummy sim from Verison.

2nd SIM losing network when activating 1st SIM data [3.2.7 stock]

When I switch it to 2nd SIM, Both SIMs have network.
Anyone else have this issue? Whats the workaround?
I am on Stock 3.2.7 Rooted.

No idea, but u tried switching the Sims around in the sim tray.. maybe one is more suited to 4g than the other!?!

Wow are you sure? If it is then its kind of a serious issue though.
I dont understand how it can be network related though?

yes im sure. just switch the sim cards. put vodafone in sim 2 and jio in sim 1. now activate the jio for cellular network. if the problem is with phone or rom, the 2nd sim should lose network right? but it doesnt. it works fine. this problem is only seen with jio.
and i had the same issue while using in asus phone with other jio sim card and airtel

So putting Vodafone in SIM 2, and then using Vodafone as preferred cellular data won't drop Jio's network? You tried this?

i've tried that too. it will drop the network.. jio needs to be chosen for cellular data to get network.
so its nothing related to phone or rom.

But I dont get it still. We are choosing "Preferred Cellular Data" when data is turned on. Why does the whole network is lost just for choosing "preferred" option? How can this be network related.
Any ROM experts around?

the reason behind this is jio doesnt have gsm or wcdma networks yet like other network operators. so it has to use lte for both data and calls. i hope u know how calls over lte work.

You are not getting what I am saying.
I am not saying Jio should use GSM.
We are setting up "Preferred Cellular Data" which when turned on, it should use either Jio/Vodafone. We are not activating GSM network mode on Jio SIM. The thing you are saying is:
Edit: I understood what the problem is from other forum. Thanks for your input

Yeah I did not know that in our phone we can only use 1 SIM active as data and other can not be used.
Thanks for your input.

When I roam around remote areas with weak Signal zone , I did experience what you are saying ... switching data and other sim signals would vanish . So I use to disable data first and later turn it on that way signals would stay . I.e.
Disable data
Switch sim data
Turn on data .
P.s. Everyone network has a fallback even if we don't use LTE ,networks fallback to device / network supported typed

Just for your info it has nothing to do with OP3 or any custom rom, It's JIO which h is an all time 4G network.
So when u chose data on any simcard apart rom the JIO the 4G band shifts to that particular sim be it idea Voda airtel, JIO will loose network as the band on that slot is 2g/3g.

no one can resolve.
ok,
faced same issue in my oneplus 3,
and it is there in every phone, and no one cant resolve it.
actually jio use its data network to make call, receive call and send sms, so if you change your network connection to any other sim, it will lose all its services.
so if you want to use both sim, your data connection must be connected with jio sim.
