Okay i see on Samsung or ATT for some reason is only allowing 3g connections. When i had my nexus one i was able to use gsm only or gsm auto (prl) etc..
Wondering if anyone successfully been able to change the settings when you dial:
*#*#4636#*#* i believe it is.

could possibly be beautiful widgets
edit - it was fancy widgets
i would love to know where you got your wallpaper
Would love a solution. The standard *##info##** pulls up the admin (or whatever) menu but I access band selection it says access restricted. The menue where you can select WCDMA only or GSM/CDMA auto etc is accessible, but the change doesn't stick. I selected GSM only and then backed out but nothing happened. Killed radio and turn on again. Still on 3G. I tried the *#*#197328640#*#* as well with no luck.
If anyone can figure out how, by any means, lock the phone to GSM or enable manual band selection it would be much appreciated.

I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.

This works, Just have to re do every time you reboot
I would also love to find a better solution to the switching- since I am now locked to a non-unlimited data plan!
-Go to the ThunderBolt's phone dialer. Enter ##778# and hit Send.
-You'll get a pop-up labeled EPST, with the choice to "View Mode" or "Edit Mode." --You want "Edit Mode."
-You'll be asked for a password. It's 000000.
-Now flip down to "Modem Settings," and then choose "Rev. A."
-Change the setting from eHRPD to "Enable," hit OK, then press the Menu button on the phone and tap "Commit Modifications."
This gave me 3G back, hopefully works for others.
gonna try that thanks

Worked for me also
Started seeing nothing but 1xx when I know I've got 3g available. This fixed it. My next question is "why was it not enabled?".
Thanks again.
I'm pretty sure it has to be set to eHRPD if you want to do simultaneous voice and data on 3G.
One of the main advantages of eHRPD is the ability to provide seamless service mobility between HRPD and LTE access networks with a single mobility management protocol. Moreover, with eHRPD, the operator can leverage the benefit of optimized handover – no dropped sessions and reduced handover latency — between LTE and eHRPD.
Do all this steps.
1. I dial ##778#
2.tap edit mode
3.password. is 000000
4.tap on modem settings
5.tap Rev.A
6.Tap on enable
7.Tap on the menu on your phone
8.Tap on Commit modifications
And after you do that your phone should reboot and you should have 3g
THEN AFTER THE REBOOT
Dial *#*#4636#*#*
Okay now scroll to the bottom. the box should say "LTE MODE" I have no 4G service in my area. So I only got. 1x. I changed my radio settings to auto PRL. Its 3G only saves battery. And for. 3G and LTE
Is (CDMA+LTE/EvDo) then after just press the home button then. 1x will disappear then 3G will appear there you go. Ladies and gentlemen

Let me guess, you don't really understand what you just copy/pasted.
The thunderbolt had this and it was nice.
Basically when I'm at work I'm in a fringe 4g area. If I leave the phone in 3g/4g auto mode then it constantly switches between the two and it destroys my battery. Not only that but it makes 4g basically unusable for me as it never stays on long enough to do anything with it.
On the thunderbolt by going into the phone info settings you could select LTE only mode.
On the Charge you only have the options of going CDMA only or CDMA/LTE auto. There is no LTE only option.
Is this something that can be corrected by an app or rom or kernel or is it built into the radio software?
I used the phone info app that worked great on the thunderbolt and on the charge it just comes up with a bunch of options like WCDMA only, GSM only and such and as far as I can tell none of them actually do anything.
Hopefully someone knows the answer to this because I like tethering to my tablets at work but if I can't have consistent 4g then I'm gonna be forced to return to my tbolt which is a shame because I like this charge alot better.
I haven't pucked up a Charge yet, but most Sammy phones let you for some fine grain tuning if the radio and other system settings via a menu accessed by a dialer code.
You could try *#*#197328640#*#* (is debug mode) and dig in from there.

Already tried that, it doesn't work on the charge. It just dials and you get the "Welcome to Verizon wireless, your call cannot be completed as dialed" message.
I believe if you go settings ->wireless and network->mobile networks->system selection change it to CDMA mode will disable LTE.
you can try dialing "*#*#4636#*#*" that takes me to a hidden menu on the thunderbolt. If it works, from that menu select "phone Information" then select LTE only. or if you want to disable 4g (Helps battery in non 4g areas) you can select "CDMA auto(prl)"

Thanks but did you guys even read my original post?
For starters, I'm not trying to disable LTE... I'm trying to force LTE only.
Secondly, as I previously said, This phone does not have the same radio options that the thunderbolt does. There is no option for LTE only. I understand the difference between CDMA auto PRL, CDMA/LTE auto and LTE only. THE PROBLEM IS THIS PHONE DOES NOT HAVE AN LTE ONLY OPTION!
I tried the phone info app that works on the thunderbolt, the only options are all for WCDMA only, GSM only and CDMA only and various combinations of them. There is no LTE only. Besides, none of the options present in that menu actually change anything, only the 2 that are built into the wireless network settings do (CDMA only and CDMA/LTE Auto).
Not trying to be a **** but if you're gonna post something to try and answer a question or help someone at least make sure you read the question.
In the same boat as you. I actually get decent service on LTE at home, and virtually nothing on 3G... go figure, but it keeps trying.

i have the same problem as both you guys and this is so frustrating. when its connected to 4g i get between 8-10mb down. i also have a samsung mifi hotspot for verizon and it shows a strong 4g signal and gets over 10mb down consistently in the very same location.
i have no idea why my droid charge keeps switching between 4g and 3g. the funny thing is the only reason i really mind is because the 3g signal is horrible. if i was getting 2mb down on the 3g like i have seen at other locations i wouldnt mind at all.
yeah i have the same issue as well, i'm really not even sure what it's testing to decide to switch from 4g to 3g, i live about 100 yards from the verizon tower i'm connecting to and have full reception on both 4g and 3g but yet it still switches randomly between the 2, we really need a way to disable 3g

Still nothing on this front? I'm afraid I'm gonna have to return my charge tomorrow then =(
No LTE only mode = no 4g for me.
I already did and canceled Verizon, I'll have to stick with sprint. I really loved the charge, and wanted to keep it and stay with Verizon , but my evo gets a full 4g signal both at home and work. Too bad, the charge was an awesome phone

It actually seems to be the way android handles 4G, either on purpose or just coincidentally.
I have the same issue at work with Sprint, 4G gives me 2-3 bars but there is NO 3G, but it turns 4G off when the screen is locked, so it sits there trying to get backups in 3G all day, spare parts lets you force wifi to stay on, surely there should be a similar switch for 4G a dev could find.
Any luck on this issue here? I have a feeling I'm in a fringe area where it could potentially switch me between networks quite often...
Is it safe to assume that an LTE-only option is impossible unless Samsung does something to enable this functionality out of their LTE chip (CMC220)?
Any updates on a LTE/4G only option?
I found out how to force LTE Only ...
Warning! If this bonks up your phone, don't blame me!
Use at your own risk!
Now that we got that out of the way, here is what I have found:
Enable the Hidden Menu option by entering the following code in your phone dialer: *#22745927
Enter an SPC of: 000000
Select: Hiddenmenu Enable
Select: OK (Your phone may reset after this)
To get to the "Force CMDA/LTE/Global" menu, enter the following code in your phone dialer: **583
If you press the LTE button, you will be fixed on the LTE network.
Reset your phone
Taaa-daa!
Note: You apparently need connectivity to the CDMA network to make phone calls & text messages (Thanks, chaoscentral!) Oh, well ...
To reset back to the normal LTE/CDMA automatic selection mode:
Go to the "Force CMDA/LTE/Global" menu by enter the following code in your phone dialer: **583
Press the CDMA button, which will re-enable your phone to default to the CDMA network.
Reset your phone
When your phone boots back up, go to: Settings >> Wireless & network >> Mobile networks >> System selection >> LTE automatic
Cheers!
just keep in mind LTE only mode means no phone calls or text messages. since those go over CDMA
Ah, I should've guessed they would make the phone code for this hidden menu option "LTE". Now I wish there was a way to only disable EV-DO 3G (leaving CDMA intact for phone calls/texts). Can't have it all I guess...
Thanks for this regardless!

Yep. I tried goofing around with a few different options on the "LTE" theme, but nothing came up.
Then, I realized that I had loaded new ROMs since the last time I had enabled the Hidden Menus option, and figured out that my Hidden Menus were no longer enabled. Once I re-enabled the hidden menus, I tried *#LTE#* (which didn't work), and then **LTE, which did.
BTW, for anyone that has had problems making phone calls after following my original settings, I have updated the post on to how to get back to automatic LTE/CDMA.
Also, has anyone tried that **583 "Global" option yet? Verrrry Interesting!! (But, spooky!)**
Ain't messin' with your phone fun?
** Anyone who gets this reference wins one "Bippy".
This is actually on old hack I used from the G1 forum. This is really useful if you are in an area where 4G or 3G is weak and you phone keeps switching back and forth to edge. Very annoying...
Install AnyCut from market
Open AnyCut and click NEW SHORTCUT
Click ACTIVITY
Scroll down to "Phone Info" and select that.
I renamed the shortcut "FORCE 4G" but you could name it anything.
Click OK
Now open the shortcut on your home screen, and scroll down to the bar that spans across the whole screen. This is the bar that controls all your network types listed here.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all. (FORCE 4G!)
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (MY FAVORITE ON G2X)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
Im sure this hack works on all android devices, less options will show for phones w/o that capability.
BetterCut will obviously also work and youll be able to customize an icon for the shortcut
Menu, settings, wireless and networks, mobile networks, network mode, wcdma only.
Won't that do the same thing without all the work?
*#*#4636#*#*
Phone information
Scroll down
Change WCDMA preferred to WCDMA Only
Same thing as well... If youre that desperate for "4g", however, if you lose 4g/3g you lose ALL SERVICE, I believe. I had played with these settings on my n1 last year. In the end, I found WCDMA preferred was the most reliable ;-)

He's talking about changing the hidden menu. There are two menus, if you change it in the non-hidden menu and not on the hidden menu, is different.
This should probably be moved to themes and apps or general. Nothing really developed here, no offense.

This isn't the hidden menu this is just the phone info menu that you can access with *#*#4636#*#*
Thanks! I skirt the edge of society and there are a few ROMs that I really like to use that don't have this option built-in. Bionix has it but CM7/Faux and others do not have the option available from the mobile networks menu. I'm sure it adds to radio life if you set it to stick with the highest signal since the phone won't be switching towers.
I have a post about this in the Q&A section, but have any of you experience the G2X using only 1X or CDMA data frequencies other than 4g?
Dial *#*#4636#*#* go into phone information scroll down and choose wcdma only and your done default is GSM/WCDMA auto (PRL)

please excuse my ignorance, but what would be the purpose of this?
so that it dosent jump around from 3g 2g if its auto and your not using data it automatically defaults to 2g i think to save battery then switches to 3g oir hsdpa 3.5g or what att calls 4g on demand this keeps it locked on wcdma or 4g to my knowledge

seems like it reverts back to auto after a reboot

Mine goes back to auto as soon as I back out of the menu. Am I doing something wrong by using the back button?
wouldn't this, by locking it, render the phone useless when traveling out of area that support that network?

Here's an alternate method I puzzled out (and then afterward discovered it was already posted in thread 751237. It's a bit faster and has the advantage of surviving flight mode; still gets reset upon restart.
Dial *#*#2263#*#* (mnemonic: *#*#BAND#*#*).
This brings up the Band selection menu which you can also access from the above method by dialing *#*#197328640#*#* then going into DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL.
Select [3] GSM BAND
Select [1] GSM ALL
Select "Select GSM All Bands"
Menu key > END
To switch back, go to *#*#2263#*#* and select [1] AUTOMATIC > Select GSM &WCDMA All Bands > Menu key > END.
Something else I'm trying out is switching the acquisition order so when it is in "dual" mode, it'll try GSM first. Even so, it will still switch to 3g if there's enough signal. Seems to help keep it on 2G though, when it would otherwise cling to a faint 3g signal with 0-1 bars.
To do that, go into the NETWORK CONTROL menu (see above) then
Select [4] AQUISITION ORDER (yes they misspelled it)
Select [2] GSM->UMTS
Select "Select ACQ_ORDER_GSM_FIRST" (at least they abbreviated it correctly)
Menu key > END
This option does not get reset upon phone restart.

I did this and now my sms or text messaging don't work help
I had this happen too, but I didn't use the above method. Don't know what happened, but when I checked message settings, I had no number under "Message Center" did a quick google search and found an ATT number "+13123149810"...now it works again.
Did u call the number
Never mind i fixed it.but now in my network type it says umts is that faster then hsdpa and are there any other number sequences i can use to tweak my phone
I'm getting RAT restricted, which I got on my Vibrant but never my Captivate...
How can I change to show the different bands?
Sent from my Samsung Infuse 4G
wcdma and cdma have nothing to do with each other. wcdma is also known as umts, the base part of 3g (and 4g when hspa+). hspa is a protocol that runs on top of this cell technology providing higher data speeds. gprs (known as edge, and some times called gsm) is 2g. you can turn one or another off so the phone does not seek and connect to both services, which could save battery life. even though ive yet to see my phone find less than 3g/4g in houston, i still dont turn it off, just in case.
