missing network mode? - T-Mobile, Samsung Galaxy SIII

I just got the S3 and noticed that I am not able to switch from a 2g network to a 3g/4g on t-mobile. I go into network settings and don't see the network modes option. Any help would be great. Thanks.

Try downloading an app from the play store called phone info, should help, if not try downloading a toggle widget, hope this helps

Tried both and didn't work. Chatted with Tmobile online and the rep said that its not possible.

Actually I think I know why. on newer samsung phones like mine its not there but in future development I'm sure you will see it happen. I have the network mode now but I didn't before.

What did you do?

I didn't do it a rom developer did it and all it was is doing the Rodgers ROM which has network mode

LTE Toggle?

I can't seem to find a way to toggle LTE on this phone? Maybe I'm just missing it. Also funny, I'm with Rogers and they tell me that I have to get a new plan in order to get LTE. However, I'm in the city today and my phone shows LTE and it is blazing fast! It is killing the battery pretty quick. Hopefully I'm not incurring extra charges??

Under your wireless and network settings tap more and then go into Mobile Network settings at the bottom. You should have a Network Mode setting you can change unless Rogers has disabled it (it's there in my TELUS version but AT&T is known to disable it for whatever reason). Be aware that turning off LTE has led to some massive wakelocks and battery drain on the AT&T version but the Rogers one may not suffer from the same symptoms so give it a try.
Also, I'm not on Rogers but on Telus I did not have to get a new plan to get LTE. Sounds to me like they were trying to swindle a contract renewal out of you.

AT&T have disabled the option. There are a few hacks or build.prop settings to disable LTE. As I said above, be warned that some users reported massive battery drain when turning it off but that may have been resolved now that fast dormancy can be disabled. In any case, there's an AT&T LGOG forum here with more info.

fix for disconnect from 3g network

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.

I remember having this issue, as well as on my LGOG, also on my S3 and LTEVO. I just couldn't remember how I fixed it, and this was my method of fixing it. Thanks! :good:

HELP, no connection after flight from NC to TX

Hey all,
I could really use some advice. I live in North Carolina, my phone has worked just fine for over a year. Monday I went on a business trip to Dallas Texas and my phone won't connect to Voice or Data services at all. What can I do?
I tried turning airplane mode on and off, removing the battery, chatted with Sprint online, called the Support number. Sprint is NO help at all. They didn't outright tell me that my phone was broken, but practically did. I guess it just magically broke on the plane to Dallas??
Even in areas with good coverage, like my bars show good connection, I can't connect. I can hook to wifi just fine, but that is it. Sprint support told me that they can't even see where my phone has connected at all since I arrived in Texas.
Should I try flashing one of those PRLs from another thread? I'm not sure what to do. I assume that as is my phone will start working again when I get back to North Carolina though. I tried reflashing a "stock" rom and some of those "#" number calls, but none of them work since my phone isn't connected to any towers. Help!
Did u by chance try ##72786#? That's the hands free activation. Will turn ur phone off and should boot back up after a few seconds

That is what is so strange, I can dial that number, even from a stock rom, and my phone doesn't do anything, it just sits on "dialing" then makes the hang up noise after 15 or so seconds.
That's definitely weird! I'm from this area so I know it's not the water...lol. Have u taken to an actual sprint store?

Not yet, since I'm here on business I don't have much time to do that, but honestly I don't think they would be able to do much more than the support person over the phone did. I'd have to unroot it and all of that before bringing it in, the folks in the store would try those ## type calls, wipe my phone and reset it, then probably tell me my phone is broken and try to sell me another phone, especially since I am eligible for an upgrade.
I don't want to actually buy a new phone until I get back to NC since I still think my phone will start working once I am back there, which would be just as confusing.
This is the same phone I brought here to Texas last October and it worked fine, so I don't know what exactly the issue could be.

If you are still having this issue I would suggest you try an app called Network Signal Refresher. It basicly updates your prl and profile by connecting you to the nearest tower

Thanks, I gave this a try, but it doesn't look like it worked. Part of the issueI think even for PRL updates is that my phone won't connect to the towers. Like with a Stock Rom in the Sprint Zone you can get to that section where you can do a Profile update and all of that, it always fails with a connection error. I gave that error message to Sprint support but they couldn't do anything with it. I will keep trying it though now and then.

Is there a good updated guide for doing that? I did that on my EVO 4G, but never on the S3. I haven't looked yet but I will check into it this evening for sure.
They could be working on the towers in the area. When they did in my area, it showed I had bars but could not text or call. I would try flashing the 2 PRL, as it helped me get my phone working until they fixed it or in your case until you get Home. I can upload it if you need it.

Cannot lock on to a 4G signal on my SM-N900T

Hi
So I have a T-mobile unlocked SM-N900T that I'm currently using in London. I'm on Lycamobile and want to try their 4G network but for some reason my phone just will not connect to LTE. 3G works fine but that's as far as it will go.
I've been able to use 4G in India on the same phone so I know it does work, but for some reason it just wont connect here. I've tried the *#2263# service menu and selecting LTE -> ALL just gives me the no signal / network icon.
Have tried resetting, pulling out the battery and SIM but nothing seems to work.
Has anyone had these issues or any suggestions?
Oh - phone is Unrooted and running the latest KK update.
Any help or advice is graciously accepted. Cheers!
They just might be using a band for LTE that the phone doesn't have/support.

Thanks, shouldn't this phone be able to handle the various bands though?

It handles a bunch of them, but not all. I'd look up the band their service uses for 4G, and see if it's compatible with your phone.

Cheers sir. I'm on the phone with them now and they don't seem to know! What are the usual bands that would normally be used in London though?

Find a phone that they sell and look up spec's and compare.

Thanks Andrew. I'll give that a go. They've called me a few times but keep reading from the same script. Was promised a call back on Sunday, but nothing and its Tuesday already!
They don't offer contracts as they are only PAYG but let me look up specs for O2, as they piggyback their network.
Sent from my SM-N900T using xda app-developers app
Ok. ..so it would seem that the tmobile phones operate on different lte bands. So I've attempted to flash an international rom on this phone and as the Eagle eyed will note, this was done successfully. I should therefore have an international modem etc now? But I still can't connect to 4G! So does this mean that this is a device (actual hardware) issue or can this be sorted by flashing a modem that allows me to connect to all bands?

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.
