In CM 10.1, going into *#*#4646#*#*, by default the network type is always WCDMA preferred. I want to make it permanently stay on WCDMA only or GSM Auto (PRL), but this setting never seens to persist across reboots.
I know it used to stick in CM7, but ever since CM9 I haven't found a way to make it stick.
Anyone know how?

I think "WCDMA preferred" is the best one/most stable one.
because if you select "wcdma only", you will have no data connection when you have lower signal.
with "wcdma preferred" it change to the 2g network to keep your data connection connected (lol), so you wont get any data interruptions

What you described is exactly what GSM Auto (PRL) does, except GSM Auto (PRL) uses a pre defined list to choose which setting, rather than WCDMA preferred which constantly pings around to find the best connection at the expense of battery.
Where I live there is full HSPAP coverage, that's why I don't really care about 2G, and by keeping it on WCDMA only I will save battery compared to WCDMA preferred.
But I have still not been able to find a way for the setting to stick. I even tried editing the default connection property in build.prop but that didn't seem to work either.

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
This makes the phone work on Verizon, right?

See that's what I thought too. ATT = GSM, Verizon/Sprint = CDMA.

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?

Mine does the same thing. did you figure out how to do it? I have been trying but I couldn't do it
I found this here in the forum someone posted and it worked for me thanks for him.

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?

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.

Thanks, John Madden.
So I finally jumped in and got the WanHu ROM installed with M's v5 patch. This thing is really nice now, hopefully it will stay that way even after I reinstall some of my apps.
One thing that I've noticed is that the ability to use only 2G networks is gone. It used to be an option under Settings » Wireless controls » Mobile networks. Any chance that may be coming back?
I know some people would probably think I'm crazy to be asking that, but in my experience the batter life was pretty much double that of what I was getting on 3G, so I'd use that mode sometimes.
Thanks for all the good work on the WanHu ROM.
You can turn off the 3g at Settings >> Wireless networks >> Data Network settings & there is also a 3g widget.
Hi,
At this point you only turn data on or off. You cannot switch from 3g to 2g.
I would like to have this feature to, because the radio at my work is very poor and the battery last much longer in 2g.

switch 2g , 3g, and 2g/3g
if i have to change the default network setting (3, which mean 3g/2g auto), i can from here:
1. from the dialpad dial *#*#4636#*#*
2. from the popued menu, choose Phone Information
3. from "Set preffered network type" You can choose several options including:
"GSM auto (PRL)" (this is usually default and means 3g and failback to 2g, depending on signal
"WCDMA prefered" (this mean 3g and if there is no 3g, then 2g), this settings seems to wotk, but if you exit and return to the same menu it is changed
"WCDMA only" 3g only
"GMS only" 2g only
hope that helps.
p.s. I use Battery monitor application, which has shortcut to the Phone Information menu.

Thanks for the reply. I was messing around in those menus and could not find a "GSM only" mode on my phone. I will look again, but all I remember were an "auto" mode, a "3g only" mode, and a bunch of CDMA stuff (which doesn't apply to our phones).
But I will look again and try out the battery monitor application program as that would be nicer than typing the key sequence everytime.
And just to expand my (rather small) knowledge of the android OS. The option to select only 2G under Settings » Wireless controls » Mobile networks, is that a framework thing that has to be added?
-J
All Sense Roms that I have come across Do not let you Switch between 4G/3G to 2G, This is only possible as far as im concerned on CM or MIUI (Like when you go to Wireless settings>Mobile Networks>2G only) has anybody found a solution to this???
You can, its just worded differently. Go to settings, wireless, mobile network settings, netowrk type and select GSM. GSM/wcdma auto is automatic switching, wcdma is 3g only, GSM is 2g.

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...
http://www.traemcneely.com/2011/12/...rottle-4g-data-anti-throttling-trick-for-att/
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 understand there are alot of threds pertaing to this throttling issue. I was given a warning text from att about a week ago now when ever i run my speed test i am only getting around 50kbs thats crazy. I live in pittsburgh which is not an LTE area yet am i screwed? or is there a work around for me????????
there is no network mode on a stock rom.. i posted workarounds on another thread which I started but can't find link now on my phone.. check my profile for my posts

---------- Post added at 11:36 PM ---------- Previous post was at 11:17 PM ----------
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)
http://forum.xda-developers.com/showthread.php?t=1342111
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)

Hi,
On my old Sony, I had something like "LTE/WCDMA/GSM" mode, so phone could successfully fall back to GSM when 3g/4g connection is weak.
Is there such an option for Pixel 3?
I've tried various settings from 4636 menu, but it looks like there is no such option. Even in "GSM auto (PRL)" or "Global auto" is still uses UMTS with -100...-110 dbm signal strength, while in "GSM only" there is -89dbm available.
Is there a settings or some adjustable through adb option, which allows GSM fallback?
I also could write an android app, in order to switch into GSM in some circumstances, if possible.
I've located in the eastern europe, if that matters, and LTE/WCDMA work best on my network, except in my office location.
