LTE mode on an LT28i won't enable

I have a stock/generic LT28i from Asia. Totally unlocked and all. I'm in the US off and on, so I got a post-paid AT&T plan with data. 3G works great on my HTC One X (European version, meaning no LTE). I popped the SIM in my LT28i and 3G works, but not LTE. If I try to change the network mode to LTE/WCDMA/GSM, it instantly switches back to WCDMA/GSM. If I put my 3 Sweden SIM in the phone, I can set it to LTE/WCDMA/GSM and see [LTE] AT&T in the network search list. So it seems like there's some switch in the software that's forcing LTE off for my AT&T SIM. Any idea what's going on and how I can fix it? I was having issues with my phone bootlooping so I did a full reflash of the generic 6.1.E.2.29.

Is that account setup for LTE with AT&T?

You may need an AT&T 4G LTE compatible SIM card. I had the iPhone 4 with the mini sim and when I got my Xperia ion they told me I needed a new LTE SIM despite the fact that my then current SIM would have fit the in the ion (and they look the same, except my old SIM had the 3G logo on it).
Maybe you current sim is att 3G.

Same thing happened to me a few times. Kept switching to wcdma preferred. Try clearing cache, dalvik and reboot. Eventually I did get it to stick. Also when this happened to me Rogers network was having an lte outage, so that might have had something to do with it. But persistence did pay off in the end.
And yes you obviously do need an lte sim and the lte apn's for whatever network you're on.

Is your APN set correctly?

Probably figured it out, and never bothered to post something to mark this thread as resolved. Now people that search and find this thread will never know the solution.

Ah sorry, I actually gave up and put the SIM in my One X (HSPA-only version) instead. 3G was good enough for my needs. Maybe on my next trip to America I'll put more effort into it.

having the same issue
I'm having the same issue, built I'm on net10, which is supposed to support lte speeds, but i don't get higher than 3g for their att compatible service.
Also, unable to root after phone overheated and did original gb att to gb lt28i, to ics.. the rootme or e4root neither one would work. I've got backups, but they're under titanium backup and cwm, of which neither can i access without root. Is there an .ftf firmware prerooted on ics that doesn't require anything but flashtool to install and add cwm, since I'm sure I'm not the only person with such an issue. If I've overlooked it, direct me to the page where it is, all I've found so far is stock roms, and deodexed, which i can't use.. Also, my boot loader is locked.. I've checked all threads about root and ion, and noon have been helpful with my recent issues..any downloads needed to rectify this and not the usual I've already done that loop back to the same popular pages would be helpful and appreciated. Thanks in advance.

EDIT: sorry, i didn't see how old this thread was...and to the above, i'm not sure if what it wrote applies to your network...but most likely you need to look into APN settings required by your carrier...

[Q] Not registered on network.

Hello, I am new to xda so please go easy on me. I have been in the wireless industry for over 10 years. I was mostly a Blackberry guy, but recently had to make the switch to Android. I would rate my knowledge of Android as just above average. Anyway, I bought a T-mobile Galaxy S3 from a guy and when we met up the phone worked just fine. When I got back to the house, the phone would not make phone calls, text, get on the internet or anything. When you try to make calls, it says "Not registered on the network". I started to do some troubleshooting and found out that the phone will work fine when on UMTS, but not when on GSM. Examining the phone, I noticed that there was a scratch on the back housing where the GSM antenna is, so I ordered a new back housing. Even after installing the new back housing, the same problem exists. I thought maybe that the phone was possibly stolen and for some reason only blocked on GSM signal. So I called T-mobile and they said that the phone is not listed as blacklisted. Not sure what else could be the problem. The person that had the phone before me unlocked it and used it on att. Of course he says there were no problems before and will not refund. Please let me know if there is anything further I can do to try to fix this phone as I do not want an expensive paperweight. Thank you in advance for your help.

Can u check and see if you have an IMEI number showing when you dial the code *#06#? You should see a 15 digit number. I had a similar problem where I could only get 2g signal. When I checked my imei it had disappeared. Luckily I had a backup available.
Sent from my SGH-T999

Might want to also check Settings>More>Mobile Networks>Network Mode and tick it to GSM/WCDMA Preferred.
And finally, since he was using it on AT&T, you might need to check the APNs and make sure they are on TMobile's and not AT&T. If not, then you can manually put them in there (don't forget to hit save when done).

The APN settings are correct, the network mode settings are set to gsm,wcdma,lte. If I go to network operators and search, ATT will be the only network that pops up when I am in GSM area. I have hard reset the phone several times. I don't know anyone with ATT or I would try their sim card in there. My sim card works in other phones. I have reset the APN settings as well. Is there a possibility that they messed something up when they unlocked the phone to be used on ATT? The IMEI does display when I do the *#06# thing. I do appreciate you guys helping me out.
Thank you,

same issue
I'm having the same issue with my tmobile phone. I bought an s3 a few weeks ago and it had been working fine up until a few days ago when the signal dropped entirely. The same error appears - "not registered on network." At first I thought it was a rom I had installd but after flashing several roms I know this isn't the problem. I've tried searching for network operators, etc but still get the same error.
Any suggestions?

Need help on Tmobile

Got my zl today excited then let down by problems with internet, so i insert sim and it picks up tmobile and auto download settings then when it start downloading google play apps it hangs. I go to chrome loop up a page get "error 502 bad request the server could not resolve your request", i have full bars and H+ but wont connect. I also notice that when i insert the sim i can just pull it out with out pressing down on it. Any help...
UPDATE: Got it working just need to tweak the APN settings, for future tmobile user the automatic download setting are not correct here is the link for Tmobile settings http://support.t-mobile.com/docs/DOC-1979

Cool. I was using tue ones from the Somy app...

I know the ZL (6506) is capable of working with T-Mobile's new LTE network, but my question concerns the IMEI number and your account with T-Mobile. On AT&T, your account has to have an IMEI number that is known and recognized by AT&T so as to enable LTE connectivity. Is this also the case with T-Mobile??

The info or where you got your info is incorrect. you DONT have to have a IMEI number that is known to AT&T to have LTE. I have changed phones prob 20 times since I got my first LTE phone and NEVER had to change it again.
You can be on the LTE data plan and everything work fine on a old dumb edge phone then put the sim card back in an LTE device and it still work fine...
LTE worked fine on a Canda Note 2 and One X

Same here. TMo does not care. I just started using my ZL teo days ago, before that was Nexus 4. Just took the SIM from the N4 and inserted in the ZL. All works!

Hey people, I'm seriously considering picking up a Sony Xperia ZL C6502 Black. I'm aware that it doesnt support LTE on either network, but the price is insanely lowwww! My question is, does anyone know what kind of speeds I can expect to see on TMO and ATT respectively? I'm currently using an ATT Gnote 2 on ST/ATT and I have a Nexus 4 as a backup which I use on the TMO $30/"unlimited" data plan. I only point this out to indicate that I don't get LTE speeds now, which sorta makes it a "You can't miss what you never had" type of deal. I roughly get about 14-17mbs down on either device. Is there any chance I'd enjoy the same with the 6502 on either of these plans??? Any help/insight or even opinions, would be greatly appreciated.

The speeds to expect will be the same as you have now.......

i just received my ZL C6502 today and noticed that the data connection does not work at all. i followed the APN settings on the t-mobile link you gave and still no dice (it does show full bars and H+ as you mentioned and when i switch the SIM to my old G2X its on full HSPA+ speed). i left the house and it was running ok suddenly and streamed netflix, etc. but when i went home it lost the connection again. I'm suspecting that this phone does not really work on t-mo's 1700 AWS even though the box says so and that i only got online outside the house because that area is on the 1900mhz refarm. is there any difference to t-mo's AWS 1700 and regular HSPA 1700mhz?! any insight or help is appreciated!!

I have a 6506 on TMo so I am limited in help. However, someone in my office has a 6502 on TMo and it is working fine. He had trouble until he manually set it. Same case as mine.
Perhaps you have a defective unit? Try removing and reinserting the SIM card. Perhaps a factory reset.
I had mine for almost a month and has been flawless in LTE when in DC and HSPA in Dallas.
Sendt fra min ZL 6506

The 6502 is the same as 6506 but without lte it should work I don't have 1900 coverage and I'm always on hspa and there's no lte were I'm at either. U need to make sure the apn is set exactly there should not be any values under proxy and port also under apn type have it blank that was the issue with mine those three things had values and was messing up internet. Also there's three different apn you have use. 1. Fast.tmobile.com (Lte), 2. Epc.tmobile.com, 3. Internet2.voicestream.com. Give it a try.

thanks for the help guys. ive gathered all that info earlier and did try the three APNs different combinations / proxy - no proxy, etc to no avail. i'm leaning on faulty hardware or messed up radio. i'll just sleep over it but so far its been disappointing :crying: great phone though...

As a quick update I did literally sleep over it and I'm happily up and running with hspa.. I literally left the phone alone overnight lol. Rooted the fone and all I need is to figure out how to get to recovery to put CWM since pressing vol up at boot is not working and flashboot isnt going either (that's for another post). Moody bastard this ZL is.. Anyway Thanks again!

I have a 6506 on TMo without any issues. I live in LA without TMo LTE, but speeds have been as high as 18Mbps in West LA. I only have the issues of bad coverage at my house, but that's just TMo and not the phone.

That's the thing you had an LTE phone AT&T had in their system when your account was provisioned for LTE so you never had a problem after that. For those people that have the ZL as their first LTE phone on AT&T they will have to first get the account setup for LTE using a phone AT&T recognizes on their network.
So basically put the SIM in an AT&T LTE phone, have AT&T provision it for LTE then once that's done you can put it in any other LTE phone and it will work fine

[Q] Connection blocked by the provider?

Hi guys... Im from Panama and i have a question let tell a little background
Here in Panama we have 2 providers that have LTE and uses band 28 this is why i bought my zenfone from taiwan with band 28 reception... this is the problem i put my sim card from one of the provider and guess what didnt got LTE and they told me is becuase is my phone that is not allow in their network (they are selling phone which is LTE ready according to them) But i friend of my put his simcard of his samsung S6 from the second company (uses the same 28 band) and my phone got LTE rightaway... So is somthing the provider can do to stop phones coming from outside getting LTE? Right now my phone is getting HSPA+ that is H+ but nothing else
And in the screenshot my phone is detecting the network which is the first LTE that you see. The second LTE with Forbidden is from the other company from which my friend have his simcard..
Thanks for the help

mmm, should you probe further to your Service provider on why it is not allow, could it be that your version was the TD-LTE? which only china has? they use difference accessing method.
the possibility of SP locking the network base on phone is rare as they need to spend extra server to cater for such banning and this does not goes into their profit and Ike customer in general. It could also be that your sim card does not have LTE function. this function is stored in HSS ( HLR) where all your services are known in the network.
Check further then post here. seem to me it is more of your sim account issue.

i post tomorrow im going to talk to my provider and hear what they have to say
Thanks for the interest

Hi good evening , well i came back and I talk to my provider this time the guy told me that my phone should work withouth any problem since it uses the same LTE band as they do which is band 28. He told me that aparently they have to activate something in their network in order for my phone to get LTE signal so they will be calling me tomorrow to tell me if I need to do somthing else. I ask him if i need to use a contract or if prepaid work too. And he told me that it also work with a prepaid service. He told me that my simcard is LTE ready and should not have any problems but told me that they will investigate. Also they dont use TD-LTE.
I will post a soon as I have the answer from them

dont trust your telecom, some truth are not allow to tell customer about, i work for 7 years for 2 different telecom.
if your phone is TD-LTE, you can never connect to your network no matter what, just see it as a door with a wrong key
if it is FD-LTE, it is most likely the settings on your profile is not provisioned, the Customer service may tell you they see it is up but in fact the system that they are reading the data from MAY not be unified with the back-end servers.
It may also because someone in-experience have wrongly provision your SIM profile.
Lastly it could be then handset is faulty with LTE service.
the best way is to call up the telecom with another phone and proposed a testing right when he/she is attending to you. ask them to forward the testing time/ MSISDN to the supporting engineering for wireshark trace. they CAN straight away tell you what problem you encounter.
you are at least someone in the forum that listen and understand truth. some others in another part of the forum are stubborn as hell..
hope you gotten the FD phone and it works for you.

Thank you very much for all these usefull information you are giving me that you gain from your expirience I really apriciate all your help and kwoledge and this will help me explain my self better when i have to talk with them.
I came here becuase there a lots of thing i still need to learn about telecomunication and bands in general (Im actually studing medicine but this calls my attention)
Well i im sure that I got a FD phone because with the second telecom (the one that my friend uses) my phone got the LTE right away so im sure thats not the problem and becuase it got LTE im sure that my phone is working all good.
Since the phone is FD then the most like thing is happening is that they havent afiliate the services correctly (that what the guy from the telecome told me) and that technicians will set up that in their side. They will call me tomorrow and tell me whats happening.
He also told me that aparently there have to be a second registration of the data service which is the one for the LTE that hasnt been done and this could be the reason of the problem.
The only thing is about the testing you you are telling me. Let me see if a got it right. Tell them to foward the time/MSISDN (its the phone numer) to engineering to wireshark trace (this is for looking that the connection and the setups are correct and the case they are not then look where is the problem if in their side or my side)
Again thank you very much. Really apriciate your help and im came here to learn and maybe some else with the same problem have the answer here

let me put it in this way
1) call up your telco and during the call,tell them that you will be performing a test for packet transfer on your phone now.
2) just try to manually connect to their LTE network by search.
3) let them know the time range that you are doing this (eg. 14:00 to 14:05)
4) get them to let the back end engineer do his/her work tracing > SGSN signalling > DPD context.
5) wait till they come back with you on the details why is it not working for you.
the handset send a signal to the radio (UTRAN) and request a data service (LTE), in this case it the radio will forward this request to the SGSN to S Gateway( just take it as signalling module), if everything is okay, it will inform the UTRAN ok to set up tunnel (in layman context, it is the traffic medium) > so P Gateway will directly link from user UTRAN to it and out to the web via PDP context.
hope this is not heavy for you, in between there are firewalls which the network engineer is able to pick up where the data is dropping for your case.
oh i see that you are going to be a medical personnel, all you need to know is that radio are everywhere and there are some instrument that is using certain band of frequency which will interupt (crosstalk) to your instrument.
the normal cases are WiFi band as it is under free band and medical usage.
For cellular, it does not matter. the reason why hospital ban it in sensitive area is because folks in the older days are using analog signal for transmission (ASK,FSK,PSK) these are to determine the data status of any radio instrument. however nowadays, we no longer use them and systems are all digitized. so it doesnt matter if you broadcast radio in sensitive room because we are using higher tech like QAM64 etc.
lastly the reason why medical still insisted that no radio in the sensitive room is all because... changing of something might affect something else, even if they know what i said, they worry that other stuff might complicate. look at Airport during flight, it is the same reason, handphone can switch on during flight but they say no. its the same reason.
The top management knows nothing and the engineers is reluctance to set things right, too much work to do.
you can read more into those, i know pilot also need to learn about these too!

hi good night im still waiting for them to reply so i think they will call me on monday. When i contact them ill ask them to do this test you are telling me and ill get back with you as soon as i have results.. Thanks and have a good night

hello a came back and with good news. The lady sold me the wrong sim card and they also had to activate LTE services. Now everything its working great thanks for the help sooty84.
Right now im getting 25Megabites pes sec down 20 megabite up i think its because LTE network is new

Unlocking 4G service on n910p Outside the USA

Hi
i have a couple of questions here , how can i access USB settings on n910p
cyanogenmod rom 5.1.1
becuse i want to try this on it .
and i want to know is the phone hardware locked when it comes to the frequency it supports ?
becuse we have LTE B3 (1800) in my Country , and the phone supporte LTE band 2(1900), 4(1700/2100), 5(850), 12(700), 17(700)
so i want to try and unlock the 4g service if it's possible.

Let me give you an insight about your query...
1. I'm too using an unlocked N910P with a GSM SIM like you where the 4G bands present in my country are not supported by this phone's hardware.
2. I've tried the post that you are referring to in the past but wasn't able to do anything because the software QSPT couldn't find my phone. Tried several times but with no success.
3. You can access USB Settings using Iodene Tools or Galaxy Tools. It has now become a paid software so the developer has removed it from XDA. (Search on XDA to find some threads related to it. You might get help from someone).
In short, it's almost next to impossible to unlock the bands as there's a high possibility that some tempering must have been done with the motherboard to unlock it, especially if the phone you got came with some Chinese firmware on it.
You can always try to check if it works for you or not.

Thank you for your explanations. I have something to ask.
I bought N910P. It was on Lollipop and 4G/LTE network was fine. But then I upgraded to Marshmallow via Odin. And now, there's only 3G with setting already to 4G/LTE. What is this problem related to?
Thanks.

See, the 4G icon that you witnessed after purchasing N910P was just a false indication. In reality, the network was 3G. Even when I got this phone, it was on Lollipop and it used to show 4G and the funny part was that I wasn't even using 4G then.
I've seen many users getting confused regarding this matter.
The only option available is that the network providers of your country start 4G services in the band that is supported in US (which again is highly u).

That 4G icon you were seeing was just HSPA+ but not actually 4G. If you see LTE then you can assume that you are on actual 4G.
