Might work for you, worked for me. Couldn't get LTE to stick and this is the method that worked.
First, pop out sim card. It will hit the battery, its ok. You don't need to pull it completely out.
You will get a message "sim card removed", or in my case my phone rebooted lol
Type in *#2263#
Select Automatic if you want LTE, select another band if you don't.
Once you made your selection, push sim card back into place and reboot your phone.
I guess you could do this to disable LTE as well, but for myself it was to get it working. CM10 based roms worked great with LTE but never could get it to work with any JB leaks.
Hope this helps you guys out!

Just a heads up. Flashed a new modem and had to repeat the process again.

I fixed it by flashing a new ROM and wiping all the data!
Someone please help! I don't know what to do!
Nevermind, I think I fixed it!
I fixed it by changing the band to GSM Preferred/GSM ALL but now I only get E. Any way I can get back 4g?
Change it back to automatic or Odin kl1 modem from rootzwiki team kang post.

I changed it to auto, and i'm getting signal. Time to check if 4g. Thanks.
EDIT: It shows signal, but Im not getting any. Can't send text or browse web. Time to odin modem.
I flashed it, and I went to settings and looked at the network mode: It was GSM only. I changed it to auto mode. It seems to still get and send texts, and I looked at band selection with the dialer code, and there wasn't a star besides anything. I think it might've worked, but I still only get e.
By flashed I mean odined. Lol

I had same issue and this is how I fixed it.
disable data connection and switch your phone off, remove the back cover and remove sim card completely. Then re-insert sim card and turn your phone back on and it should ask you to re-enable data connection once it boots up.
let me know if this helps

I did this, but it didn't ask me to turn it back on, so I turned it on manually, and still only E.

Other phones receive 3G? Perhaps T-Mobile is servicing your area? This has happened to me but I had no control over it.

I'm having some issues. I am on Incredible HD RLS 2, I haven't been able to get on WiFi and this isn't the only ROM where WiFi isn't working. It will just never connect. Well, I tried to install ICS Official global CM9 upon initial boot it said it couldn't read my SIM. I powered down pulled the SIM put it back in and put the phone back together and then I couldn't get any service. No matter what I did I have no service.
Yes I followed all the instructions, wiped everything, flashed the proper gapps and the kernel.
Since that didn't work I went back to my nand and still no service. Anyone have any suggestions?? Please help
On global cm9 rum through setup and change network mode to cdma/evdo becuz it defaults to gsm

Awesome, got service back, but WiFi is still not working. It just forever searches and never connects to a network. Anyone have any ideas?
This happens to me sometimes and restarting my router usually clears it up, not sure if you have tried that, just throwing it out there.
I can't reset the router, I'm on a college campus. I have the latest firmware and radios,switched out rom after Rom and still WiFi doesn't work. Any other suggestions?

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
have you gone into settings> more settings> mobile newtorks>and taken a look at your access point names and your network mode?
yes
I even confirmed with Rogers and settings are correct
Are there any service mode type ways to switch on/off data? Maybe I inadvertently did something

Try setting it to WCDMA only, and then use the network operators button to search for networks

Will try this again. though not sure of that option.
for me under network mode it gives me choice of GSM
HSPa
BOth with auto connect
or those two with LTE auto connect.
Right now if I try to select HSPA only ct it does't change and reverts to GSM/HSPA/LTE (auto). Seems it will only accept a choice that allows it to default back to Edge (GSM)
Anyone know if there are some deeper settings to

If I change the sim and put it in my old s2 I get 3g speeds right away so I should at least be getting that and I know form the day I got it that LTE was working well in my home.
it depends on what they flashed maybe they flashed a different antenna because the freq's of the tmo version are diff than the rogers version
Wasn't a flash. It was an unlock code for Rogers entered at the invalid SIM screen. They were not told which network I would be using it

Can I flash the modem if I am not rooted.
Sent from my GT-I9100 using Tapatalk
Does flashing the modem show evidence of such?
I.e if this attempt at a fix fails my recourse is to return the phone as defective. Don't want there to be any evidence of tampering that could void my warranty
You can flash modem.without rooted.
Zip.file.modem.through cwm or .tar modem file through Odin.
And if you are under 14 days of purchase, reset your phone to get your log minutes under 30.
But I guess you.won't need to do.that, flashing.modem and reset should work.

Well did factory reset before risking modem flash.
Low and behold while i had to reinstall and setup everything again, LTE is now working again.
Not sure what happened. Will ultimately root at least to back things up.
I am not sure if this is the right place to have this but I have a tmob s3 that I am trying to get the 3G on att to work. I know the lte won't work but the hspa should thou since it has the proper bands for it.
I have been able to get the 3G to work by manual setting it by the dialer but it won't make calls until I set to it back to automatic it. It won't go back to 3G until I manual set it back
I have tried every apn settings and nothing doing...
I am not sure but maybe I need to try a different radio? I am currently on the latest jb radio.
Any ideas?

I think you need to make sure your phone sim is unlocked. You can do it by some method on these boards or you can call your tmobile and ask them for the unlock code.

If its unlocked you should only need to pop the att sim card in and it shoudl automaticly set the att apns(on CM10 or any aosp rom, rebuild TW rom), and get hspa+, tho if your on stock rom you need to add the apns manually since the apn.xml inside framework-res.jar dosnt have them.
Yea its already unlocked and it gets service it just doesn't make the switch to hspa+ unless I manual force it to do so and it doesn't always work sometimes it will show now service

im having the same issue, how do i manual for? im running on 4.12 aokp
Just curious if anyone has figured out a way to get passed the "RAT selection option is restricted" message to select specific bands (*#2263#). It doesn't appear that the old fix of removing the sim card with the phone on will work for us; the sim card is too close to the battery and maintains contact until the battery is removed.
Edit: So I found a way, if you turn off your phone, pull out the sim card, turn it back on and enter the code you can select a band to force (in my case LTE). Then you have to turn it off and put the sim back in, the setting will be persistent. This is a huge pain in the ass though, so if anyone has a better way I'm all ears!

Yeah that is pretty much what I said in my edit, the airplane mode stuff isn't necessary, I was just wondering if anyone found a way that didn't involve rebooting your phone multiple times
Until someone makes an RAT unlocked radio I thiank thats the only way.
