I picked up a used Samsung Galaxy S i9000 that was on Virgin (CDMA?). I rooted it, and put JB on it. From another device, I have a Telus data plan that is on 4G. Looking at the i9000 specs, it says it supports GSM and 3G. This where I get confused. The Telus plan I am on is 4G LTE (data). Does this mean that this Sim could fall back to 3G if I use it in my Samsung? I have ran a number of unlock tools (including the Samsung Galaxy S Unlocker) and think that my phone is unlocked, but the radio shows that there is no connection. When I ran the unlocker, it completes but does not say "its done". I can see that I now have the correct APN setting for Telus. The phone sees my SIM and my phone #. And I have the nv_data.bin file ( was not there before running the unlocker). When I look at the phone details, it sees my SIM, knows my phone number etc. It just won't connect. It also has the correct APN settings. If I try to dial a number or use the data, it does not work. Wondering if there are other settings I am missing?
I think the issue is that the sim only runs on Telus 4G and does not fall back to 3G (what the phone is capable of), but again, this is where I am green. I don't know how this works. Does the phone 'ask' the Sim to fall back, or does the network and Sim dictate to the phone what network it will use?

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

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...

Says 4G. I think we are good

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.
So I put my SIM in from my g3 (which was T-Mobile and getting great lte) and phone was working fine then for some reason reverts to 4g and no lte. Check my account online and my phones imei shows up as an old blackberry which downgrades my plan automatically.
I can stick SIM back in old phone get lte, switch again and it reverts. Called and customer service can't seem to help. Anyone else with T-Mobile note on att having issues ?
I have been having a different issue. Every couple of days, I would loose all T network connection as the APN "ATT Phone" would become unselected for a as of yet undetermined reason. If I select it, everything works just fine (include LTE) till it unselects itself a day or two later. I cannot determine the cause.
If I look on my account it shown some "dumb" phone whereas I used to have a Note 2. I do get LTE. I use these APN setting, which seem to show up as default when I press the reset on the APN menu:
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
See if these are the setting your SIM selects. If not, you can try unselecting "ATT Phone", change it and select it after saving. But perhaps you need a new SIM which T should be happy to give (or maybe it is a couple of $) you if you visit a store and say you lost your phone and the sim.
Thanks for the input. Yes I have tried deleting apn settings and adding the ones like you listed. It didn't help. Get 4g but no lte. Went to att they pretty much just said too bad it's not our problem cause it's a T-Mobile phone.
So far no issues running it in Manhattan for a couple weeks - I can't tell the difference between this, my OnePlus One, and my old AT&T Note 3 - all using the same AT&T SIM.
I did get some slow data speeds while in Williamsburg last weekend, but my wife's AT&T iPhone 6 had the same issues so I don't think it was a phone issue.

Oh okay. I don't know why mine is having this issue. Have used several T-Mobile phones on att without issue
Sorry to say it appears the Note 4 is polled or "phones home" and immediately shows it's non-approved IMEI. When I change the SIM from my T-Mobile Note 4 to my ATT Note 2 the MyATT page almost instantly changes from BlackBerry7100 to "Smartphone". Not sure what to do because it'll surely cost my LTE speed.
I've been using a T-Mobile Note 4 on AT&T since the week it launched without these problems. I have a feeling I'm jinxing myself or that it's only a matter of time before it does happen. What's weird to me is that on the AT&T page it shows I still have my old LG G3.
Are you guys using custom ROMS or Kernels or anything? I have pretty much rooted from day one and froze a bunch of stuff and immediately got rid of the Carrier IQ.
Well let me chime in. I never got lte on the note 4 until I got tired of slower speeds haha. I had an iPhone so I went to at$t to get another sim card but brought my s3 so they wouldn't know of the note 4. Problem I think was putting it straight into the note 4 and not settle into the s3 first and get all required info. So I was without LTE for a while until I decided to try again for it. So I called at$t and told them I was not getting LTE on my phone 5s so they changed the imei # to the one for the 5s. Still didn't get any lte so I went to an at$t store when they said to pick up a new sim. I used the iPhone probably for about an hour and got LTE. So from that point I put the nano sim into the note 4 and now I've been getting lte for over two weeks and great signal coverage. On my account it says I'm using a dumb phone but when I go into upgrade options it says I'm on an iPhone 5s.

And yes I'm using a nano sim not the usual micro sim
(I posted this in both the T-Mobile Note 3 and AT&T Note 3 forum)
So, every once in a while it will connect to the T-Mobile/MetroPCS (I have MetroPCS but since MetroPCS uses T-Mobile Towers, it (SHOULD) work and has in the past)
On my Samsung Galaxy Core Prime that I bought from the MetroPCS Store, it works absolutely perfectly.
It always is connected to the T-Mobile network.
But this phone, Samsung Galaxy Note 3 (AT&T -- BUT I flashed Alliance Rom for T-Mobile, so it has a T-Mobile ROM) will not connect. As I've said before, if I get it at the right time, which is completely unpredictable and restart my phone it will connect but 10 minutes later it will disconnect and tell me "Selected Network (T-Mobile) is Unavailable"
Before, when I had the stock ROM (Lolipop AT&T) it did the same thing Except when it disconnected it would tell me "Phone not allowed MM#6"
The IMEI is valid and not blocked.
I do have service
I manually set the carrier to T-Mobile and also quick note when I click "Search networks" it only gives me T-Mobile, AT&T and Virizon (But it does only these three on my Core Prime too)
This phone IS UNLOCKED
and my Sim card is also Unlocked
And also, I have tested another Samsung Galaxy Core Prime's Sim card with this phone ( I have this phone, and one of my family members does too and also has MetroPCS )
It did the same thing
THOUGH when I tested with my other family members Cricket SIM card, it worked Perfectly!
Cricket, uses AT&T Towers from what I remember. So this makes me think that the phone, since it is AT&T it will connect to AT&T over everything else no mattter what I do. So,
Do any of you think buying a T-Mobile varient of this phone (Note 3) would fix the problem? Instead of this AT&T varient?
I also tested this with a Blu Studio Energy 2 (It is not carrier specified) and had the same problem. It would work but sometimes it wouldn't and there was no way to guarentee it not disconnecting, and no way to put it back on the network that I knew of it just happened at random
If I put my sim card in my Core Prime, turn it on then turn it off and put it in my Note 3, it will connect for a couple seconds.
ANY HELP -- Would be appreciated.
I fixed this by myself.
I didn't realize this, but you need to call MetroPCS and add your new phone's IMEI.
Hi there, well I got this new tablet and its pretty good apart from I cant get vodafone 4g to work on it... I got a 4g data plan put the sim in and only got H+ max... when I put the sim in it said due to sim change/new sim will need to update settings but as the device doesnt do it automatically will have to do manually but vodafone doesnt show any settings info on their site when I clicked on the link... spoke with vodafone a few times and so far no luck even though they say the tablet supports 4g and they support the tab... now I swapped my phones sim with the tab sim and at first my phone wouldnt do 4g either till I installed the settings they texted me across (phone supports auto settings) and then the data card got 4g... but the phone card in the tab didnt and did the same message saying get the settings which I cant do as they are not on the vodafone site... anyone have any idea? many thanks
ok so after a lot of searching it appears it might be the fact that the tablet I ordered does not in fact come with b20 (800dd) which is what pretty much all the providers in the UK uses... I think this is hardware and not firmware related (is this correct) so I might have to return it... the tablet was advertised as having the 800 freq range so I either need to deal with H+ or return... ffs just set it all up too...
