I bought N920I on ebay, and it is factory unlocked version. When I use the New iphone with att, it is working well, but it seems the signal is not well enough and the GPS (goole map) is not as accurate as Iphone 6 one. So I went to ATT retail store, they told me I should update my IMEI in their system so might solve the signal problem. So I just gave them my NOTE 5 IMEI, but they tried couple times and was unable to update it for me. So I went back home and called ATT customer service , they finally override the system and helped me successfully updated IMEI . I am wondering does it really matter to update IMEI when I switch from IPhone 6 to NOTE 5?
I guess I was lucky. Went in to get a new nano sim. They put in the imei # and it came up right away as the n920i!
Speeds are crazy...88 down 40 up.
That's 4x better then what I got on my Tmo Note4
The modem on international devices aren't optimized for AT&T's network. HK modems are particularly wonky outside of HK. The IMEI controls features (EG: visual voice mail) on AT&T. The SIM talking to the network negotiates LTE and types of access (EG: tablet SIMs don't do voice and text when inserted in a phone). AT&T uses the SIM to determine what's acessible (EG: voice, LTE). Foreign phones aren't recognized by AT&T because their IMEI's aren't in AT&T's database. I have an international tablet with voice and text so AT&T picked a dummy IMEI to associate with it so I could get visual voice mail. Bottom line is any wireless performance issues you're experiencing are caused by the phone and network settings won't change that. Welcome to gray market phone ownership.

Briefly, I have had a few issues with my device. One was the inability to register my S/N on HTC's EU site. Several other reports of this have surfaced as well. That is being addressed through MobilePlanet's very helpful rep James. Glitch on HTC's database apparantly. The second, as Dan mentioned, is my phones total failure to see the 3G network. I now know why...
I spent almost an hour on with AT&T's data support and the guy said the reason was the failure of my devices IMEI# to register the devices hardware. There seems to be no hardware profile for the TyTnII ansd therefore it comes up as an "unknown device" in their provisioning system. I confirmed this on my visit to the store this afternoon as the rep there showed me the screen and sure enough, it comes up as unknown, and the setting for this selection is GSM, not UMTS which all of their 3G phones are set to. He said, your device "does not exist" in a valid profile as a UMTS device and therefore will never be able to see a 3G signal even if I was sitting under a 3G tower... He showed me his phone which is 3G capable and id did indeed have UMTS and a valid hardware profile.
So, looks like I am SOL for 3G unless MP can help. Not happy tonight... I am going to speak with MP again tomorrow or Monday, and see what they suggest, if this can't be solved, I may be returning my new baby. 3G was an important selling point 4 me as I do a lot of data xfers.
BTW, I'm in NorhtEast NJ within a known 3G area. area.
hummmmmmm??? granted i'm in dallas, but, i'm on AT&T and i just popped my 3G SIM (used for a 3125) into my Kaiser and i get 3G with no issues. i would have tried the ATT guy's SIM in your phone (and vice-versa) to validate the profile issue. you didn't mention this, but i assume you have a 3G SIM , correct? i'm interested to hear if other ATT users have had this problem....what about trying a new SIM or one from a friend that has 3G?

Yes, that will work. Per AT&T data support, since mine is an unlocked unit with an IMEI# not in ATT's system, it will never be able to do 3G. Everyone that did get it to work just switched out their existing 3G capable sim to the new Kaiser. I came over from Verizon, so unless I buy a cheap 3G ATT phone, I'm out of luck.
Switching the sim for a new one did no good, same IMEI#, so no help.

I made the mistake of giving at&t my new IMEI# when I went from the 8525 to the Kaiser. Now my phone profile is set to GSM only since it is an unknown profile in there system. I will either have to buy a cheap 3G phone and use that SIM and IMEI# so there system thinks I have a 3G phone or return the Kaiser since I won't be able to get 3G. Right now it is not an issue since I don't live in a 3G area. hhhmmmmm

There is no need for 3G SIM card. Any card should work. I'm using old AT&T Blue SIM with no problems at all.

True any card will work. Did your old phone have 3G on it already when you swapped it?

Bill will test it tommorrow when he borrows a persons sim who has 3G. If it works then they are correct.
You got a pretty good load of BS from the AT&T guy. All you need is a 3G capable phone and the right provisioning to get access to the 3G network. Signing up for a MediaNet, MediaMax, or PDA plan should so it. YOu should NEVER give them your IMEI # unless it is an AT&T phone. Cuz at that point, if there are any issues that require deviations from their "scripted" support, they will say that's the issue. Unless you happen to get lucky and get a real technical support rep.
Just tell them you got an aftermarket unlocked Blackjack and you want the 19.99 MediaMax 200 plan. If they ask for an IMEI number, tell them that shouldn't matter. You can then make any changes to your plan online if you'd like. And that should get you access to the 3G network.
Thats the problem. Talked to several CSR and they won't change the provisions becauses we did give them our IMEI numbers already. They got us there but there are workarounds and lesson learned.

Not so -- my last two phones (Kaiser & Wizard) have been unlocked & not registered with AT&T, and I get 3G HSDPA. However, I don't have (and never have had) a data plan -- I pay $0.01 per KB for data a la carte.
I have a suggestion based on what i'm facing: try disabling the HSDPA in settings and reboot (it will ask you to reboot anyway) then see if you have 3G.

That is total BS sounds to me you dont have the right settings on your phone. Did you use the Network wizard to set things up for you? that might be the problem if you did. I have AT-T and a brand new Kaiser direct from HTC and have no no no issues what so ever with 3G or HSDPA i also think i am getting a little a HSUPA here and there
FYI and a request for some assistance
I use quite few different phones and one day my account froze on me. I had been using a palm treo 650 because my kaiser was out of battery.
when i reinserted the sim into my kaiser days later phone worked but no data no sms worked again. in any att phone all shapes and sizes. I thought it was from the treo because i used the data no problem.
its a company acccount need password to talk to csr at att.
after researching and seeing this thread I retracted my steps
the only other thing i have done is reported an imei on my account for a tilt i needed to unlock for a friend before there was an unlocker.
I believe the imei on file controls my provisions.
Provisions
the only solution to no data on phone that was working is provisioning a pit stop to a service center.
Is it possible to create a solution or is it totally a carrier fix at this point? Is there any other way to adjust provisions with out a walk in or call?
FYI
to change a reported imei number simply call 1-(916)-843-4685 and have them update your device to what ever imei you want them to have.
Note once they update the system make all your changes for rates online the only info att has is what is provided at point of sale or givin by the client
this is just some info to add
Anyone else on AT&T unable to get LTE? The APN settings that auto-downloaded are correct according to AT&T's documentation, but I'm only getting H+.
Your GPRS could be disconnected. I'd you use app advanced signal status you can look at settings Beyer to see if your set up correctly
MasterBrick SCH-I545 Galaxy S4, XdA mobile app...
I had to use my girlfriends IMEI for her Nexus 5 for it to pick up LTE. Before that, I was only getting H+. Try to get an IMEI of another ATT LTE Android phone and it should do the trick!
Can't get LTE to work
I need some help. I have the new, unlocked, Sony Xperia Z3 Compact and I can't get on the AT&T LTE network as well. Here are the steps I have taken:
The Setup
I have a Samsung Galaxy S4 that is on the LTE network with no problem
My AT&T account had a Lumia 820 device tied to my account (and old device of mine) and it worked fine for LTE on all of my future pones, including my S4
I purchased an unlocked D5803 Z3c from Handtec
My Activate Attempt
Went to the AT&T store to pick up a new nano sim card
I gave my new (Sony) IMEI number to the AT&T rep (stupid move, clearly) and they loaded it under my account
With the new sim, my Z3c could place calls and send/receive text messages
Data would not work
My Resolution Steps
I looked up APN settings online and tried several different variations
The HSPA+ Cingular APN settings worked, but left me without LTE service
I could not get the mobile.att.net APN and LTE settings to work
Reading Android Central and XDA, I discovered that others had this issue as well
Using forum advice, I called AT&T
The AT&T rep did confirm that my Sony IMEI number was registering as a "2G" phone, which is why I did not get LTE access
I put one of my extra LTE device IMEI numbers on my account
My phone still won't connect to the LTE network
I notice that even though they registered an LTE phone (and they confirmed it came up LTE), my AT&T account page shows an old flip phone silhouette
The rep noted that there was nothing else they can do...so I basically have to deal with it
I'm posting on XDA to leverage the wisdom of this crowd
I remain confident that this will get resolved, yet frustrated at the same time
I'm at a loss and wonder if I have to activate this nano sim in another supporting device or the like. Thoughts?
Thanks in advance for your help.
No clue, but AT&T tech support confirmed that my IMEI is registered and my previous two devices were all LTE devices. I have no idea what's going on either.

Are you having the same issue? Do you see the cartoon sketch of a flip phone in your account as well?
What you have to do is give them the imei of an LTE capable phone. It absolutely does not matter that you will not actually be using that phone.
If you already have an LTE phone, just switch your SIM to your z3 when it arrives. It is absolutely unnecessary to call AT&T with your new IMEI. Anything AT&T tells you to the contrary is flat out wrong.
Issue resolved!
Bottom line...do not give these clowns your Xperia IMEI number.
When they entered the IMEI number it flipped my data plan from a grandfathered unlimited plan to a pay-per-use plan with no LTE (why they couldn't figures this out last night, it beats me). He was talking about my wife's plan and her unlimited data. I then noted "mine is unlimited too" and then said it wasn't. You can only imagine how things went from there.
The unrecognized IMEI number automatically switched me off of my plan.
They have me on a temporary 3GB plan, as the support rep couldn't get me back on the unlimited plan. They have to send the change to their back office team and it will take a week to get it back.
My phone now has the 4G icon versus H+.

Nope, it actually still shows my previous LTE-capable phone.
I actually also initially had this issue ; I was sitting in the AT&T &T store on the phone with tech support until the sales rep realized my phone wasn't showing up in the system as an LTE device. He input a bogus LTE IMEI for me, after which I restarted my phone. It's been working for me since then
Whelp, I guess I'll go to the AT&T store again later, then.
So everything that is claiming to have LTE ----> Do you have a 4G icon on your phone or LTE? I am in US, went to ATT store ---they entered an imei of a Samsung Galaxy S5 and now it shows 4G. If you go into mobile networks preferred network mode it says 4G preferred/wcdma/gsm. I am assuming this is just due to the UK software version not being the same as US...

IMEI problem rectified, they reverted it to my previous phone's IMEI. Now displaying 4G. Sweeeeeetness.
It's just silly that AT&Ts LTE is tied to the IMEI in their system and not simply having an LTE capable phone.
I ported a line to use with my Z3c and gave them the IMEI of an AT&T HTC One so that LTE would work, but they would only send me a micro sim because according to the IMEI that's the sim I need. Tried to tell them I need a nano sim but the gal on the phone said she couldn't send one, I'd have to go to a store pick one up.
If you are going from an LTE phone that uses a nano SIM card to the Sony Xperia Z3 compact, it is not necessary to contact AT&T. You will need to manually add the APN settings on your Sony Xperia Z3 compact. Here is the path to get to the APN settings..
Settings > More > Mobile networks > Access Point Names > press + to add a new APN
Enter in the following settings listed below
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
Save the changes you made, select the APN you just created and reboot the phone. Everything should be working from there.
Here is where I got the information from: http://www.att.com/esupport/article.jsp?sid=KB424489&cv=820&_requestid=838329#fbid=ecLfo9YLvXa
So I do have the 4g icon in my status bar. Does this mean that LTE is working fine?
The only reason I am asking is because on the MY ATT page I do only see the silhouette of a flip phone.
Edit: My phone automatically downloaded internet and MMS settings when I first booted it up. Is this what others are doing?

Yes, you are getting LTE on your phone
LTE = 4G in Europe
4G = H+ in Europe
3G
etc
If you do a speed test, you will see that you are getting LTE speeds on your phone
Problem here too. I just went in to get a nano sim. The guy hooked up my number from a note 2. Does not show data. He said I needed to put in my IMEI number from the box. I didn't from recommendations on here. The problem is that I didnt have a rebutle sp? Because I really don't know how it works. He said if my note 2 was lte, it should work. I don't know what the heck to do

I would try again, maybe try to get a different service rep. The IMEI from an AT&T Note 2 should work.
I carrier unlocked my Galaxy S 5 and wanted to know if it would work on Verizon's network.
It might work on Wcdma, & Lte. Maybe other chime in.

I'd like to know as well.
Because I'm switching and my S5 is carrier unlocked.
When I put my VZW SIM (which works fine in an iphone 6) in the phone there is no indication of a problem, i.e. wrong sim, etc.
However the signal icon is generic and if I try to place a call it gives me that dreaded not registered on network pop up.
If I look in the properties on the phone the (VZW) number is displayed but it does not show as activated on network.
So my question is does the S5 (actually purchased at a Best Buy store as MetroPCS and unlocked to use on ATT) have the proper modem to work with VZW? If not I will need to sell it.
Interestingly enough I put the ATT SIM in the (VZW) iphone and it worked instantly. Placed calls, send SMS, and get LTE speeds with nothing to change whatsoever!
Here's a fairly good read on network bands and compatibility between carriers....
It should help.....g

So. Complicated issue here, and as expected my regional carrier's staff has been less than helpful. So I have a (AT&T originally) UNLOCKED nexus 6 with Android 5.1 installed. After having it unlocked I attempted to insert my SIM from my new Moto X (2nd Gen) on the nTelos network (a smaller regional carrier that I believe generally acts as a Sprint MVNO). This was a new activation on the network the week before with the Moto X having no issues at all. After the SIM insertion into the old Nexus 6 I get only voice and text. No data. So I attempted to replicate the APN settings via the star menu and re attempted connect. Still no data. I get voice and text, and there is an exclamation right on the signal strength locator. I've read many articles reguarding MEID's and whitelisting, but I assume if it was a white listing issue there would be no service at all. And there have been many similar successes with Nexus 6 devices like mine and other carriers including sprint and verizon. As far as I can tell my APN settings are identical to the Moto X that works just fine. What am I missing here? Is it the lack of the MEID in the regional carrier database? I still feel there must be a solution especially given the fact I can make and receive calls/texts. Any one else have some similar experience? The staff at the nTelos store is less than helpful. States it just can't be done but can't explain why nor will make an attempt to solve my issues. I can post whatever info is needed. Thank you for your time.
I believe Nexus 6s purchased directly from AT&T are SIM locked to their network.
Hi Guys, I'm wondering if someone more knowledgeable can help advise. I've spent 12 hours and cant activate my Unlocked Qualcomm Note8 on any of my service providers (SMN-950U1.)
I want to use it on Boom Mobile Red (Verizon MVNO)
I cant get the Network Operator to configure, when I select Verizon it fails on configuration. I'm not referring to APN because I do not even get calls, the Operator is listed as "Emergency Calls Only". The Sim works perfect on my Pixel XL and iPhone 7 Plus. This phone was purchased unlocked form Samsung direct with clean IMEI. I called Samsung and they have no idea, they said the phone is defective, which I believe it is not.
I had an issue activating with Sprint and still have not had Data working, though I was able to get calls. I've given up w/ Sprint and will upgrade that line with a iPhone X.
I inserted my friends Verizon Post Paid Sim from his Moto Mod phone and everything was perfect (calls, TM, LTE calling) and the phone got LTE+. Is it possible the Note8 unlocked will only work with the big 4 carriers, ST and TW? I read a similar issue people from Boost Mobile have when they insert their sims it says invalid Sim. I really have no idea what is going on - Boom doesn't have many customers and their support team has never delt with this issue, they said the phone is defective. Has anyone been able to use a Unlocked Note8 on Boom? I've tried flashing various variants of firmware, including Verizon with no success. I'm puzzled with what is going on.
