[2G/3G/3.5G] Preferred Network Types Explained & How To Change It Easily

I'm noticing most of us are on the AT&T Network, yet there are those that do not want or need 3G/3.5G and want to use 2G or have another carrier so they cant take advantage of the speeds because they are on a Network such as T-Mobile.
Obviously someone using primarily or mainly 2G will see significantly more battery life.
This is good for someone that rarely uses data service or goes online using WIFI for the most part.
To change or edit your Preferred Network type go to your Phone app
then enter the following: *#*#4636#*#*
>Phone Information
>Set Preferred Network Type
Now you are able to change and edit the way your phone looks for and uses the Network you are currently on.
The Terms are explained below:
Preferred Network Types change the type of frequency the phone searches for.
Android is used on several devices that can gain access to different cell carriers.
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
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.
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.
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
When using the 'only' options you should still be able to make calls.
To put things into perspective, The Nexus One is set to WCDMA preferred as default and the Droid Incredible is set to CDMA auto (PRL).

My Samsun S does not recognise my sim.The sim works in another phone. I tried to change the preferred networkto CDMA preferred, as it is on "unknown". It does not allow me to change it. Please help, as this new phone is now doorstopper.

This option has not worked on any Sense ROM I have tried for the HTC Inspire. It works great on CM7 but does nothing but stay on 3G on sense.

For sense Rom if you are rooted this is how you do it
From today screen
1. Hit menu
2. Click settings
3. Click wireless and networks
4. Scroll down to mobile networks
5. Choose network mode
6. Change to gsm
This will lock you into edge only. Even after reboot settings will stay phone must be rooted or it does not hold settings
If you want 3g/4g only. Set tab to wcdma only

I have tried this on CoreDroid and ARHD and no luck. Went through settings menu and used the *#*#4636#*#* options and neither one sticks. Could it be my radio and hboot and the interface with Sense?
EDIT: Going to try ARHD again and see. If not, I will try CoreDroid.
EDIT: Still a no go for either ROM...ClearDroid included. So far, I have only been able to do this via either method (plus a built in toggle) via CM7. This begs the question of whether this is a software issue with HTC Sense.

Strange I remember when I was on stock sense Rom the settings wouldn't stick. But as soon as I rooted and downloaded a custom Rom it did stick sorry you are having trouble. Here is my complete rom/radio/kernal
Coredroid 9.4 = Rom
12.56.60.25u_26.10.04.03m=radio
Lordmod 5.0 is the kernal
I also changed my build.prop settings to enable real 4g and tweaked gsm gprs umits huspa hsdpa I do not know if this had any effect on making settings stick

Thank you for the feedback. I am running the same radio. I will revisit CoreDroid again. Perhaps editing the build prop is the way to go in this case. It is the one thing I have not tried on any of the ROMs for this phone other than to rename my phone from Desire HD to Inspire (which was only on one or two ROMS). Would you mind sharing your build.prop settings and tweaks so that I can have a baseline to work with? I'll tweak from there as necessary to meet my wants.

I edited only these in build.prop
ro.ril.gprsclass=10
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=7
ro.ril.hsxpa=2
Reboot twice and don't forget to backup your settings
I used prop editor to edit build.prop its easier but I don't have a link for it but I think there is a link in that thread I posted below

Thanks. I will give this a shot. I have edited the build.prop before but only for the purpose of changing device id name. I don't remember what I used to edit it but I am sure I can find it again. No worries about the backups. I kept copies of original build.prop saved plus did a nandroid right before making the changes. Never can be too careful. Will post results later tonight on whether this was success or not for locking in the ability to switch between bands.

In that thread I posted is the build.prop app 8th or 9th post down. That tweak is just for faster data speeds and I do not think it will lock u on to 2 g or 3g but who knows

No go for 2g/3g options. Have not been able to really say about faster data speeds but definitely something I will keep notes on. Back to where I started. Looks like CM will remain my ROM of choice for now.

Preferred network type set to unknown
Hi frnds.. i had accidently set preferred network type to unknown by going in secret setting by using the code *#*#4636#*#* in my Micromax A54 and now my real imei number is changed into 00000000. My mobile is not recognizing any sim and on notification bar it says ''searching for service''. I am not able to reset previous setting i.e. unknown to gsm auto(prl) or gsm only or wcdma only. Please help me how can i resolve my problem.
Your help will be appreciated. thnx in advance..

hi i have samsung note2 my network show unknow but every thing is ok call sms is fine how to i fix it to my network when i restart it they show gprs but when i call some one they going to unknow

Turns out the device has two SIM card slots - one strictly for GSM, another with WCDMA support. If this is the same for you, change SIMcard slot and the preferred network type will change

Thunderbolt not connecting to 3G in non-LTE 4G areas?

After doing a manual root, the Thunderbolt connects to LTE fine but when there is no LTE, the 3G won't connect and the phone doesn't receive data.
Advice?

Try checking to make sure you are not in LTE only mode. Dial *#*#4636#*#*, select phone information, scroll down and go down and make sure you are on the CDMA + LTE/EvDo auto option and not LTE mode.
If that doesn't work, try downloading "reset connections" from the android market and running that app when you enter a 3g area out of 4g range. It may be a handoff issue from 4g to 3g towers.

##778# hit dial, edit mode, password is 000000, modem settings, Rev. A, change to enabled, instead of eHRPD, hit menu, commit changes.
try 3G again.
I assume like me, you are in a section where Verizon's Hybrid Network isn't working, and so you must tell your phone to revert back to their regular 3G network.

We have 4G in Pittsburgh, but there's a spot in Squirrel Hill that I go through on the bus in the morning where I drop to 1x, and I'm fairly certain that there is 3G there. However, there are other areas I've definitely seen 3G. So, it seems a little mixed. We're definitely early adopters of this new network

The fix
Phone ##778, edit mode, 000000, modem parms, REV-A change from ePHRD to enabled, menu, commit, reboot, problem fixed.

seems to have worked for me. I was having a problem with syncing too, hopefully this fixes that as well. Thank you!

Not to familiar with TB verizon, but friend bought his TB and I saw there was 4GLTE on it, and now nothing, no icon not in wireless networks, nada!
What is this "fix" for?

Any way to force LTE only mode?

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!)**

[Tweak] FORCE 4G with anycut

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?

How to Fix AT&T Data Throttle Your 4G - Your Data Usage is Among The Top 5% Of Users
There is a nice little APN fix. Just change the APN to Phone and force your phone to use HSPA in your phone's settings. I have instructions with a screenshot...

How do you perform the first step on the skyrocket?
1. Go to Settings > Wireless and Network > Mobile Networks > Click Network Mode and force your phone to use GSM/HSPA (Auto mode).
I don't see "network mode".

Click Access Point Name..
I am now getting 512k vs 150k.

Found another trick.
I named the access point the same ATT pta, then I put Phone under the APN setting.
Put your phone into GSM/HSPA (auto mode) let it connect to the network,
then go back and put it as HSPA only.....I'm getting 1-2g+ bypassing the throttle using HSPA+ works like a charm.

Att Throttle Samsung Skyrocket
i did all when i click on Mobile networks i see access point names and network operators and use packet data. When i click on network operators is says Default setup doesnt allow me to do anything. Please help

Same here. Don't see 'network.mode' selection. Please help. Does it have to be rooted?

I am still not sure where/how to pick "GSM/HSPA (Auto mode)" on stock rom. Thats not an option.
What I have are:
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.
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. (Maybe the Samsung Galaxy S will take advantage of this???)
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
(Cut n paste from another thread, dont know if these are applicable to Skyrocket/LTE)

Thanks for the pointer to the thread but my whole point is that I dont see those options and for some reason my network mode changes dont stick.
So if I disable packet network, switch the APN, change the network mode and then enable the network again, I see that it has gone back to GSM?WCDMA/LTE auto mode again.
So for some reason my network mode changes dont stick. Also, I am on stock rom, could that be the reason!

Custom ROMS give you the options you are looking for.

I am confused ! If the stock radio is *locked* to use LTE if available, why are some people reporting to lock onto HSPA+ network with stock ROM. Are they exploiting some bug?
I have tried various things but I cant switch my radio to anything except GSM/WCDMA/LTE auto mode. It seems to come back to that mode.
Do I need a reboot after changing the mode.
I am using *#*4636#*#* to switch the mode.

Switching APN 's worked like a charm ;o)
