[THINK TANK] Turning off 3g allow only edge.

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!

3G fix for Thunderbolt

LTE is back online, please follow steps at the bottom of this post to get everything back in order.
*If you are in a 4G area it is advisable to make sure you switch to eHRPD to avoid bad hand offs between 4G and 3G as well as allowing simultaneous voice without hiccups. I noticed my GPS was not working last night so it is possible eHRPD settings will affect your gps or it could have just been due to the network issues.
As most are aware both the LTE network and eHPRD are down (a special version of 3G for the Thunderbolt only). To get 3G data back you just need to change your settings back to the normal 3G network. Here are the steps:
Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose enable and click OK, hit the menu button and then press “Commit Modifications.”
Restart your phone and you should see 3G is working
last step (may not be necessary)
dial *#*#4636#*#* go to phone info, then set preferred network type to CDMA auto (PRL)
I hope this helps anyone that is left in the dark by this outage.
If you are running a non-stock dialer or a rom that included a dialer it may prevent you from entering settings. Flash this zip to go back to stock dialer
http://www.mediafire.com/?9yf09ri4t2mip4z
For those that want instructions for after LTE is back on
These 2 steps will put you back on LTE and then put you back on the correct 3G for the Thunderbolt, when its back up.
dial *#*#4636#*#* to get LTE, go to phone info, set preferred network type to CDMA + LTE EvDo auto
Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose eHRPD and click OK, hit the menu button and then press “Commit Modifications.”

Isn't this selected by default? I changed it to "enabled" let it reboot, and 3G is back on.

By default we are setup for the eHPRD 3G network on the Thunderbolt because it allows faster switching between 4G and 3G. Since both network features are down you have to switch your settings to the 3G network used by all other Verizon phones.

eHRPD is the new 3g in thunderbolt I believe you need to select enable.

yea but in your instructions you said select eHPRD, which is already selected.

Yes enable, sorry I was too fast in typing out my instructions and goofed

one more step guys, if you are on auto cdma/lte settings, you might have to go in to
*#*#4636#*#* and select phone info and then select EVDO only to get 3g under preffered network settings.
It would be nice if you could add this to OP wakestrong. I think people in 4g area have cdma/lte auto option enabled so in the phone settings the phone is still trying to pick up the older cdma.

So this has worked for everyone? I tried this earlier with no luck and just did it again with no luck either :/

Look post above. You might have cdma/lte auto enabled under phone info menu so it is still searching for 4g and older 3g.

technically if you would have waited it would have eventually gone to 3g but might have taken a while, but that option is just an easy way of doing it.

Thanks a million! It worked. Good night, I was on 1x ever since I flashed the stock rom. I thought for a while it was an error on my part. Talk about bad timing.

Thanks OP.
First the PSN is down for a few days, and now Verizon's new network. Wth?

lock your infuse to cdma

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

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.
champoux said:
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.

In settings there are only options for 5G/LTE or LTE.

I can but during events with large crowds, 4G network can sometimes get so congested where 3G actually works better.
It has to do with having a bad mobile network operator as well

Question 2G on A13

Can anyone who has already upgraded a Pixel 6a to A13 tell me if the "Allow 2G" option is still available in Settings-->Networks-->SIMs ?
Some people on twitter are saying that they cannot set 2G as a "preferred" network anymore, not sure what it implies.

The option is still here yes. However, you can't set 2G as the preferred network type.

Try this..
Open Dialer
type :- *#*#4636#*#*
Click on Phone info
Select Preferred Network type & Scroll Down & select "GSM Only"

Thank you guys.
Current situation is bizarre for me. I need 2G working for voice only. My carrier is switching 3G off, and I cannot have VoLTE working (despite the corresponding option being enabled and carrier saying that it should work). Currently, when I make a phone call, the 4G data connection gets disabled and voice travels over 3G or 2G. When the phone call is over, 4G data connection gets back on. Since 3G is being switched off, if 2G suddenly became totally unavailable, I simply couldn't make phone calls anymore.

I believe you can get a number with Google Voice, and call thru the app. I haven't used it in a while tho.

Not sure if you have tried enabling this option in the SIM settings (something to do with the Tensor Security settings as Google deem 2G to be less secure.
