how to turn off 4g?

is there any way to turn off 4g on Samsung Charge?
I have thunderbolt myself, I chaged my radio setting to CDMA Auto.
But it doesn't work on Charge!
Help me!

To disable 4G
SETTINGS -> WIRELESS AND NETWORK -> MOBILE NETWORKS -> SYSTEM SELECTION -> CDMA MODE

Go to the market and download the LTE Switch and put it on your desktop. Problem solved.

Anyone know how to force only 4g mode?

Not that I'm aware of. Also, I'm not sure if that's a great idea, considering the spotty coverage so far.
That said, the new EE4 update that came out yesterday (2011-JUN-08) is supposed to improve 4G reception/selection.

Mobile data problems still...

Ok, I know I have complained about this before but when I am connected to mobile data I do not get what I am supposed to get.
I don't get "H" "4g"or "3g"all I get is
"1x"and "E"which sucks because the speed blows.
All I would like to know if there is a fix for this because I have had 4g with the stock rom and now I am on cdma which is odd
I also cannot select a band when I go into the "*#*#4636#*#*"menu -> phone information -> menu button-> select band
What I get is a "select [unsuccessful] (whichever band) message and sometimes a force close.
I don't know what to do any more because I made sure that the apn settings were correct and that I was connected to a tmobile network provider
Someone help please help me
Thanks in advance, googleme1

I would like to know this too because all I get is edge. If I reset connections, my phone picks up 4g and within a minute I'm back on Edge. It sucks. But what are the correct settings for above as I am using CM7 RC1.

Try to get a baseband switcher. I'm on the defy and that did the job.

Well the g2x is relatively new and from my knowledge there isn't any basebands for it as well as radios...although there are some for the
Lg o2x which will probably brick my phone

Sorry that no one has attempted to answer your question. I've ran into this exact issue before. Redownload the rom and reflash it again. Once the phone boot up do not touch the phone for about 5-10 minutes! This step is important! Let the software settle in. Once its settled in then reboot the phone and then wait till your carrier (T-Mobile) pop up and then unlock the phone and depending on your area's coverage you shall now have 3g-4g signal.

T-Mobile is undergoing technical issues from a phone call I made over to them. They said that they are working on resolving the issue ASAP and that it should be within a couple of hours.

Your welcome and completely restart every single step you took to get the rom on the phone. That includes redownloading the rom and then reflashing it and just wait 5-10 minutes once it reboots. The reason why I say redo the step completely is because it could of been a bad download, a bad flash or just that you didn't give the software sometime to settle so to eliminate all possible issues do the whole step over completely!

Unless 2g mode is enabled by mistake. Did you check? Its in settings, wireless and network, and then mobile networks.

Yes, i made sure that the 2g only option in the mobile networks tab was not selected...i dont know what else to try...

[Q] Mobile Network Help? Urgent!

All of a sudden my 3g network quit working! For some reason, I'm also unable to receive sms messages, though I AM able to make calls. The up arrow on the 3G indicator flashes constantly, obviously indicating I'm trying to access data, which I am, but the down arrow stays inactive except for a few random flashes (just once and then a few minutes of nothing again). I've tried toggling airplane mode, turning mobile network on/off, rebooting the phone and I even went as far as resetting, all to no avail. This is my home where I have NEVER had any troubles with 3g. Occasionally, the phone does recieve data for long enough to load a page or anything else but the majority is just getting network errors and failures to load. If anyone can help, it would be greatly appreciated.

Are you rooted? If so what ROM are u running?

Also, just to be sure, what done are you using and who is your provider?

No, I'm not, sorry for not stating that. It's an HTC Wildfire (CDMA) running on a small network here in NC (Carolina West Wireless).

And your provider?

Are you Sprint,Verizon..
Sent from my PC36100 using XDA Premium App

Sorry Slag, the name of the Provider is Carolina West Wireless. Anyway, here's my up/down stats since last reboot: pppsent: 1315 pkts ppprecieved: 519 pkts

Check your apn settings and make sure they match your service providers settings.

Ok. Honestly,you need to be rooted.LOL. Seriously,it sounds like a network error. I would call customer service,and ask for technical support. If you are with Sprint,ask for technical support. They should be able to walk you through it. Do any of your friends have same phone and network? Check with them,and see if they are having the same issues. You stated that you did a factory data reset,can't remember if that requires reboot. Sure it does,though.Also, try doing a battery pull.

Not since the factory reset. Anyway, to be honest I cant find apn settings anywhere. From what I understand it should be settings>wireless & networks>mobile networks> But "Access Point Names" is missing.

4g lte?

Im looking for the setting and cant find nothing. I know sprint lte is not really pushed out there but there should be a setting somewhere or will sprint release an update for that?
Sent from my XT897 using xda app-developers app

When you go into the settings, there is a "More" tab, and there you can find the 4g settings, although there aren't that many... hope this helps!
Btw, this is my first post on xda!

Network mode problems after cm10 and sim switch

I'm using an infuse 4g with JB 4.2.1 cm ROM. I unlocked my phone and put in a T-Mobile prepaid sim.
I'm supposed to have 4g consistently but I'm getting 2g(edge), 3g(umts) and on very rare occasions I get 3g(HSDPA)... Its approximately 70%-%20-%10, respectively. And these changes are all happening in the same household. No tower switching.
I only have the option to switch on 2g only in my network mode settings on cm10... APN settings are correct and all T-Mobile can say is that I won't get 4g if the tower doesn't support it..
Are there any possible solutions to obtain 4g at all?
If so, how do I keep it on all the time?
Do I need to install a new modem?
If so, which?
Any comments and/or answers would be greatly appreciated.
Thank you.

Using Uckl2 at the moment. FYI.
Also, I know the modem is for WiFi but does it affect carrier data? If not what can I change to affect my data connection?
Sent from my SGH-I997 using xda app-developers app

I always thought the opposite. I thought modems were only for mobile data. But does switching modems help?
Sent from my SGH-I997 using xda app-developers app

Could increase or decrease your signal and rate at which data is downloaded and uploaded depending on your modem of choice. Battery life is also affected minimally (usually).
Sent from my SGH-I997 using xda app-developers app

Hmm, didn't know that... Well thanks for the lesson but have you tried switching modems?
Sent from my SGH-I997 using xda app-developers app

I switched through a couple and uckl2 seems pretty stable but no change on carrier network service.. I want to put on kl3 but I can't find the download.. Not too many options for my phone though.. That I know of.

It might just be your location.
Sent from my SGH-I997 using xda app-developers app

Since I changed to cm10 and switched to T-Mobile sim I have yet to have 4g. Tried where I'm at now and up to 70 miles from here... Very weird. I can't tell if its T-Mobile or the ROM.

Have you had it before on the same phone? Have you tried using another 4g phone?
Sent from my SGH-I997 using xda app-developers app

Yeah I had 4g on it before, on att and on metro. Both while using stock Froyo rom and GB aeon rom.
Sent from my SGH-I997 using xda app-developers app

Weird, it sounds like its the network then
Sent from my SGH-I997 using xda app-developers app

Yeah that's what I'm thinking but when I called T-Mobile, they said that they cannot diagnose a non-tmobile phone. The only info that they can give me is that they assume its my location and possibly the modem but they cannot guarantee switching modems will work. Doubt they hack phones though, Lol
Sent from my SGH-I997 using xda app-developers app

from my recollection..not from experience:
T-mobile or networks other than AT&T will only give you: edge or 3g.
No 4g or hpsa+
to get better than 3g, you need to be on AT&T

When the phone is on "H" I ran a speed test and its pushing 5 to 7 mb download speed. Is that close to 4g?
Any advice on how to stabilize the network?
