Help with mobile network

I have recently flashed my phone from stock GB to aokp JB. The fone works great and would like to thank all the people who posted in here and got me up and running. My problem is that after i flashed i dont see tmobile as a network anymore. I only see att as a service provider. I have a tmobile sim card installed. i can make phone calls and data is fine but sometimes when i go underground and lose service my fone acts funny. For example phone.com fail. or i'll lose wifi...
any help would be appreciated..... yes i did for get to save my apn settings and i did try to search through the forums to no avail..

So I flashed it in recovery but Tmobile still doesn't show up as a selectable service. I also reflashed JB just in case. Should my fone be able to run on att network with with a tmobile sim?

I get hspa+ on my fone when I am outside my house.... I get about 20mb speeds more or less..... Everything else works and roaming is off.... Its just for some reason I get bad reception in my house and it affects my wifi.... On GB I didn't have this happen before and I did have bad service in my house as well. Is it possible that's its just a carrier name issue then?

Go to Mobile Networks and select Access Point Names. If you don't see T-Mobile US use the menu and select New APN.
Name T-Mobile US
APN epc.tmobile.com
MMSC h h t p colon slash slash mms.msg.eng.t-mobile.com/mms/wapenc
Everything else should be the same.
If that doesn't work, call TMobile and ask for the settings.

if I made a nandroid... is it possible to get the settings from there?

I can only access H+ and not LTE

I recently got a LTE sim card, and an LTE data plan with Fido. 4G worked for about 5 seconds (I even did a speed test) and then now it's permanently on H+.
APN is set to LTEmobile.APN but when I change to Network Mode LTE/GSM, my signal goes blank and stays like that until I go back to GSM/WCDMA, which doesn't make any sense.
I'm using Task's 10/28 Build, which is the only build that doesn't have black screen unlock.
I tried updating to his latest 4.2 but LTE still didn't work.
Any ideas on what is wrong?

did you not read what he said? He has an LTE sim card. To the OP try a google search and see if there are any different apn's. Its not rom related because task650 gets LTE speeds with his rom. Or if your phone is unlocked and you know someone else that has the same phone or LTE sim card pop it in and try it out

Some ROMs have incorrect Fido/Rogers APN settings; I'd go over what's in the ltemobile.apn settings and compare it to a known good set (such as the ones in the stock ROM).

Soft bricked my phone by going back to rooted stock ROM through Odin. Guessing I should have formated system. Anyways fixed it up. Got lte working on rooted stock. Then when to miui no lte. Read that lte is a problem with many on this ROM so I lose. Hope I can get it working eventually when off stock.

Carriers use different labels for H+/LTE - ROMs differ in how they interpret the actual signal speed.
Some ROMs accurately reflect the network speed, some don't.
Some carriers promote/sell speeds that they cannot provide in every area.
There are many possible explanations as to why you are experiencing this.
You should provide your ROM, carrier, APN settings, network speedtest results, etc. for more in-depth answers.

Oh to have your problem haha. Yes I have 3g on it. Sprint hasn't finished updating the Raleigh area, so I get spotty LTE. In fact, due to their handoff bug, I only get lte for a few seconds before it switches back to 3g (on previous roms)

Which baseband you got? I doubt we have different ones, since the phone I think only has 2 modems out.
Edit: After looking at the post here http://forum.xda-developers.com/showthread.php?t=2451426 I don't know how to distinguish v7 and v8. Regardless, I highly doubt that's the issue.
Have you tried changing your Preferred network type? Mine is set to "Global" On occasion, I've seen Data enabled turned off seemingly spontaneously on other devices, sooo check that too

actually when i reflashed with new gapps I had Global/3g/2g/LTE as my network options. after it goes out, all I have is LTE/3g/2g and anything but LTE kills radio.
I wonder whats going on. Maybe google is restoring some type of data?
i know the guy who flashed yesterday and had it working, lost data after some time, and I wonder if he ran into same issue I had.

It sounds like the ROM doesn't know how/when to fall back onto 3g to answer phone calls. Did you try 3G or 1x only to test calls?

it switched fine initially. showed 3g in status bar, sent SMS. started a call.
once the preferred network changes, anything but LTE kills the radio. "Emergency Calls Only" is what the status is in the quicktiles. With a blank radio signal indicator.

so i can go into the *#*#4636#*#* menu via the dialer and change the radio mode to EvDO only and get 3g and can make calls and send SMS. If I choose CDMA/LTE it transitions to the LTE network then ****s the bed and won't send SMS or make phone calls. It does send MMS and have fully functioning data on LTE. However, then its just a tablet.
I'm going to wipe and reflash again, as I did mess with a whole bunch of crap now and see if I can get anything figured out.
Any ideas?

Baseband display number is the same from ZV7 to ZV8, hoping LG gives us an actual name for the next one.

LTE bug

Hi I seem to have a problem getting LTE. I'm using a galaxy s3 i747m on Fido and I'm using stock Rogers ROM. I have a problem with LTE. I used to get it everywhere most of the time but it now only works once in a while. When I do finally get LTE it only works 30% of the time. I have full signal LTE but it doesn't load any webpages or anything. Once and a while it does though. I have tried bootloaders, modems, different Roms and I can seem to solve this problem. Does anyone know how I can fix this?
Thanks. I need my stable LTE back.

By modems do you mean basebands?
Have you look into your Access Point settings and preferred network type?

Yes by modems I mean basebands. My network type is LTE,3g, 2g. My APN is right. I can get LTE but when I do nothing loads at all. I have tried different Roms, different modems, different kernels and nothing seems to work. I did have LTE that worked before though.

When did it stop working? Do you remember what was done to the phone?
If nothing particular was done before that happened, you might wanna give Fido a call so they can check your connectivity and perhaps get a new sim card.

Well it stopped once flashed aokp ROM. I have a cut some card so that could be the cause unfortunately. I'll try a new simcard and see if that fixes it. I might also try flashing back to complete stock but I'm not too sure if that would help at all. I remember having LTE as soon as I turned it on and now it never turns on.
Thanks for the info!

You can backup your stuff, fully wipe and go on from there. Worth giving it a shot before changing your sim card.

I actually swapped the Sim card and that didn't seem to work. I'm just going to go back to complete stock and see if that works.

I went back to stock and I still can't get let. Do you think it would be a good idea to change my flash counter back to zero? Nothing seems to be work and I know my phone doesn't have a problem. It has to have something to do with what I'm flashing. Any other ideas?

I have literally tried everything lol. I think it has something to do with our phones picking up the wrong signal. I live in Mississauga Ontario and I get LTE in the middle of the city but it doesn't connect at all. All it does is take forever to load a page and times out.
Sent from my SGH-I747M using XDA Free mobile app

So I fixed the issue. I added another APN to my settings. So I have two ltemobile.apn for fido. I turned off the phone removed the sim. Turned the phone back on without the sim and entered service mode *#2263# and I put it to LTE all in the settings. I then turned the phone off and turned it back on with the sim and lte is working and my speeds are back. After that was all done I entered back to service mode *#2263# and put the network back to automatic all and now the phone automatically connects to LTE when I want it to.

[Q] At&t S3 On MetroPCS LTE/TmobileLTE

Hi guys, i have a s3 i747 that has been unlocked and ready to be used on other gsm networks.
I went to a metropcs store and had the phone activated and sim card inserted, my imei was connected fine and everything went great.
I instantly had EDGE(1x or 2g) and even after hours of searching and phone calls to metropcs all i can find is APN solutions that dont work.
I currently live in Dallas/Ft Worth so i know the LTE coverage for Metropcs/Tmo is amazing it just ill not connect to LTE.
How do i get LTE to work on this device ??
Phone Specs
Has root
Unlocked
S3 i747 from At&t
Worked fine on At&T for LTE
Su keeps for closing at start because it says security issues
Stock rom on 4.3 but it says custom build under about settings for some reason.
Data speed is about 0.09-0.10mbps
Any help would be great. Sorry if this is a repost of other types of threads but i never found answers and did not want to re awaken old threads.

This issue seems popular this week.
If it's like the others, it's an issue from unlocking. the nv file gets damaged. The solution so far is to use nv-reader-writer to copy another phone's nv file and replace yours with it.

have you tested *#*#4636#*#* method? just mess around with the preferred network and see
I'm on Tmobile and worked fine with LTE

Where could i find a nv file for the s3 i747?

Sir, i tried to use the nv tool but it keeps saying phone wont connect.
i have the drivers installed, it sees my ports for the phone, i go to connect and it does, but when i click read device it fails. Ive had no boxes checked, one box checked and both boxes for spc and fast read(i think it is) checked. No Go either way. Any suggestions for this? Then i can see if the NV Writer is a solution. Also i can use my own NV file right??? Or would that just be a corrupted file being reloaded ?? If thats the case how do i find a clean NV file for a Samsung Galaxy S3 i747 for AT&T??? Thanks again for the help brother

I would think you would need to load an NV of a different s3. I will try to load my NV here in a few and see what happens. PM me also

Ok guys i tried some settings. a guy i know tried to inject the AWS for Tmobiles band freq. and it didnt work.
SOooooooooo im thinking we might have to skip AT&T phones on metro/tmo and get a tmo phone or a AT&T phone that supports AWS band freq.

Wait....How are you getting 4g ?? it might not be LTE but da*m its faster than Edge. Could you tell me your apn, and your settings if you changed anything since you first switched to metropcs.
Like dial star, hash(number sign)twice, the 4636 and star,hash star, hash and go to device info, then screen shot, then scroll down and screen shot again where i can see "set preferred network"
also man are you sure you have the S3 I747 from AT&T??

Make sure you are checking your connection in Settings > About Device > Status > Network Type
You cant always trust what's displayed in the status bar. Especially when using a custom rom or using a device on a different network than it was intended for.

Yea man I know. I've checked everything and says edge still.
I think it's based on your radio and kernel. Brad what kernel and radio you using.?
I'm on 4.3 Rooted and stock.
