Try going to dialer and hit *#*#4636#*#*, it will take you to a menu, select phone information, I use WCDMA only, that connects you to 3g only. Once you choose a option that suits you, go to you Mobile Network Settings, and find Network Operators, choose search network, whatever networks are available should show up, choose yours. This should reconnect you to 3g.

it seems after investigating tht my phone didnt root properly and i have no idea whats happened :S i did (oh i cant post URLs intill after eight posts :/ it was on 'myhtcdesire dot com' method 2) , help lol

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?

it could be a hardware issue

Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino

I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!

Get a new sim from tmo if it's over 2 phones old.

Exactly. Although I got it before I saw your post, you were completely correct.

definitely try a new sim card.

I've tried 5 different SIMs now. It's not a SIM issue. The other poster has a different issue but mine's identical to the OP's.

Haha yup, thanks though! I know, it could always be something so tiny and stupid too, eh.
Someone posted in my own thread and said to do the following. Will by trying it once I get home. Could the OP please try this and report back? I sure hope it works!

first open the dialer
Type *#*#4636#*#*
select phone info
look for the only drop down box - hit it - choose wcdma prefered - hit back 3 times
Go to menu settings woreless and networks
hit mobile network - it need to be ticked
hit mobile networkS hit APN or Access point names - hit the menu button - choose reset to defaults
go back to mobile networks - choose network mode, select wcdma only - look for the 3G or h sign when it shows go back and choose gsm/wcdma auto
if that fails do a manual net work selection - choose your networks 3G option

I did try every setting in there. The new sim card fixed it! So I guess our problems are different.

[Q] HTC One X - Force LTE connection?

I have ALWAYS had very poor AT&T service in my house, from my iphone 3g, iphone 4, iphone 4s....as soon as you pull in my neighborhood AT&T service just goes to ***
I got the One X however and realized I can pick up LTE here when the radio first turns on! I can put it on airplane mode, take it off...and I'll get LTE for about a minute. I get 10mbps down instead of the 1mbps when it's just on "4G"
However..this can barely make it through a SpeedTest as it's 1 or 2 bars of service...then it switches from 2 bar 4G LTE to the 3 or 4 bar "4G"
The phone is thinking I get better service with just the plain 4G so it forces me to connect to that....in reality it's a tonnnn slower and much worse.
Is there any APN setting or any root hacks to force the LTE connection? I get LTE pretty much everywhere in town (las vegas) but like I said my neighborhood doesn't seem to be on AT&T's maps!

If you go to your dialer and type in *#*#4636#*#* it will take to a screen where down a bit from the middle is the option "select network type" tap that and there is and "lte only" option. I have read that this works to force only hspa+ but can't confirm it for forcing lte. Give it a shot though.

I found the screen....Has a bunch of options with "LTE Only" being one of them...however...when I click on that option it flashes as being set to "LTE Only" for half a second and then reverts to the default option of "GSM/WCDMA/LTE auto"
Damn, thought you were on to something!

Did you try any of the other settings just out of curiosity to see if any of them worked?
Edit: just read through a thread that is doesn't work now. Bummer

This does NOT work for forcing either HSPA or LTE. It always reverts back to auto. AT&T does not let you choose your network, period. We will not be able to choose the network unless and until we get the Rogers ROM working on the AT&T units (or until someone builds a custom ROM giving us the functionality of Rogers).

Yes, if you would have read the other posts you would have seen that we already mentioned that this doesn't work.

Necro'ing this post because it has recently helped me in getting LTE coverage and I hope it helps others. This code mentioned earlier in this thread, *#*#4636#*#* and method of forcing LTE does work on Rogers devices.

Sure it does... rogers devices and debloated ROMs are the only ones that can be forced into LTE mode. It's AT&T ROMs that can't

If you are rooted and have an unlocked bootloader, try a version of CleanRom or a stock rooted rom which is not an AT&T base. I have been able to lock my radio to LTE (only when not making calls that is) with CR V and I am on AT&T. The only thing is that when you make a call you get bumped to 3g/HSPA because AT&T doesn't do voice over LTE

[Q] Default "Preferred Network Type"

Can't find the answer anywhere. I am looking for the default network type that my phone came with. It got changed along the way and messed up my signal/data network.
I have an HTC Sensation 4G from TMOBILE USA
Thanks in advance.

Default network type should be GSM Auto (prl). Hopes this helps out

Hi,
Reflash the ROM.
You will only lose mods and add-ons.
Your data and settings will remain intact.

[Q] XT1045 won't connect to LTE

I picked up an XT1045 (Moto G LTE USA) recently from Amazon and had T-Mobile ship me a new micro-SIM, then called them to activate it. I know there are LTE towers around (had customer support tell me as much) but I never see "LTE" in the status bar, always "H" or "H+". Granted, download speeds in San Jose on HSPA+ are pretty fast, but I am wondering if I'm missing something fairly obvious. I have the default LTE APN selected.
I did unlock the phone using the Motorola site and rooted it. Could this interfere with LTE operation somehow ?

Which APN are you using. You should be on fast.tmobile.com

I have the similar setup (xt1045,unlocked bootloader, rooter, stock 4.4.3 and stock kernel) and don't have any issues. It did take a few hours after first boot. I am in a refarmed area however. Mine defaulted to the lte/fast apn.
a few things:
- tmobo indoors isn't great in all places, so try outside
- if you're on wifi, they downgrade to hspa/3g to save battery, you may not see lte until you get off wifi
- you may be over your monthly 4g cap
to be honest, their hspa+ speeds are same as lte out here anyways

Even if you are over your monthly cap, you still connect to LTE. It just lowers your speeds.

Thanks all for the info. I'm using the T-Mobile APN that came with the phone (fast.t-mobile.com), wifi off, have tried indoors/outdoors.
I'm pretty sure I'm not over my data cap -- my previous phone was a Nexus S and my data usage habits haven't really changed yet
It is a much snappier phone and the HSPA+ and wifi and GPS really are much nicer. I like having the microSD slot too. So I can't really complain too much.

Try this:
*#*#4636#*#*
Phone Information
Scroll down and force it to LTE Only
Turn on/off Aeroplane mode if needed.

Never saw 'Phone information' come up. I'm assuming this would be the same as changing 'bearer' in the APN setting to 'LTE' instead of unspecified (tried that already, it just seems to get no data at all then) ?
Have not had airplane mode on for these tests.

So when you dial *#*#4636*#*# , what is the first menu on the top?
It's not the same, cos if you set it there, it allows of 3G connections if no LTE available (dunno if you force it from Settings -> More.. -> Mobile Networks -> Network Mode -> LTE ).
The Airoplane mode is just to "relog" to the carrier network , you just cycle through it On->Off

The last four characters were #*#* in your first reply, and that didn't seem to have any effect at all. When I tried the sequence above and pressed dial, it first said 'USSD code running' and then 'Connection problem or invalid MMI code'.

The correct combination is *#*#4636#*#* and you dont have to press dial after that, the menu should pop-up right after you press the last character.This is not model specific either, it works on all android versions/roms.

Apparently doesn't work on this phone. It's ok, google led me to a couple of apps which appear to do something similar. Thanks for the insight !

Finally got the "LTE" indicator while outside eating lunch near work today. I was amazed that the speedtest.net app reported ~30Mbps down / 20 up. Didn't have to mess with the default T-mobile LTE APN. I guess T-mobile's coverage is just kind of spotty, but maybe the nearby tower was just upgraded or something like that
