Can you set to WCDMA preferred? - Nexus S Q&A, Help & Troubleshooting

Issues w/ Preferred Network Type
Sometimes but not always, when i set it to a particular preference, it doesn't stick. Sometimes i do WCDMA only but 1 minute later, i go back in and it's reverted back to GSM/CDMA auto (PRL) default....Anyone having this issue?

There is a different menu that controls the radio on the NS.
I am not sure how you get to it through the dialer.
Download Anycut from the market.
In Anycut Add a new shortcut to "testing" which is under "activity".
Open "testing" and you should be able to to elect the band type. this one does stick
Done.

Testing just brings you to the wireless/networks screen which only has lock to 2g

WCDMA only = 3G. Using a shortcut to Testing instead of *#*#4636#*#* did stick after rebooting. Thanks for the tip clubtech.

whats the difference between:
GSM auto and GSM/CDMA auto? Shouldn't we just have it on GSM since tmobile doesn't have cdma?

Testing just brings me to the network settings screen. What setting did you get to?

Phone info. In Anycut there is also a shortcut for it. Look in Activities / Phone info.

Anycut works for me...but I noticed that with WCDMA only, sometimes I do get 3G on top, but the bars go from green to grey. I end up reverting to default GSM/CDMA.

If you call *#*#4636#*#*
And go to the Phone Information ...
Can you set the preferred network type to WCDMA preferred?
Because, I cant ...
As soon as I set to WCDMA preferred, closed, and re-check, it will be back to GSM/CDMA auto PRL
Both modes are more or less the same, but auto PRL will prefer EDGA on low signal.

Yes it can. I noticed the same issue when I first got the phone but now on custom rom it stays on the wcdma preferred but still resets after a reboot. Wcdma only stays after reboot.

Ah, you use custom ROM.
But, I am using stock ROM ...

Hey are you still on CM7Alpha2? Coz I am using this and mine can't set to WCDMA preferred permanently, it still reverts to the PRL.

Can't get it to stick on mine either. Stock rooted phone. Tried using anycut as someone else recommended, still won't stick.

Same here, preferred won't stick, so I just changed it to WCDMA only. You have to reenter your SMSC number after that though.

i don't need to do that, it works when i set it to WCDMA only, and it stays

I tried to edit the build.prop as discussed in other threads
# Default network type
# 0 => WCDMA Preferred.
# 1 => GSM Only.
ro.telephony.default_network = 1

but ro.telephony.default_network wasn't in my build.prop and adding it as a line didn't seem to do anything for me, at least it didn't help with the dropdown in the phone information screen.

Same problem here.........

Did you get any issue updating SMSC?
I spent some times this morning because I accidently changed the SMSC via *#*#4636#*#*
And I could not change it back!
Every time, I got error "Update Error".
No matter what I put there:
+3112345678
+31 12345678
003112345678
3112345678
At the end, I used my old Windows Mobile, and changed the SMSC there.
It works

The number to enter there is not the phone number. Its a modified version of it, I had to load another sim card fro the same operator and refresh then copy down the number to update it back to my sim card!

Yeah, and that's the problem. In Windows Mobile, I just enter the phone number of the SMSC.
SMSC is usually a phone number.
I checked with my provider (Vodafone NL) and it is a phone number.
If it is not on Android, then I don't know what it is
I read on Nokia (Symbian), the SMSC can be entered as phone number as well.
Probably Android is not using standard format for SMSC? At least on the user interface (to update).

[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.

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.

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.

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.

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

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?

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.

[Q] [SOLVED] Changing Frequency Band

Hey all,
I just moved to France with a i9020a Rogers phone. According to this (http://forum.xda-developers.com/wiki/Samsung_Google_Nexus_S) my phone can cover the 2100 frequency band and according to this (http://www.worldtimezone.com/gsm.html) France's 3g frequency is 2100. I just got a SIM card and my text and calls seem to be working, however, I can't use data at all. Any ideas?
Phone info:
Type: Rogers i9020A

I tried following the steps below, however, after deactivating and activating my phone radio and pressing menu my phone just went back to the home screen. I remember doing this with gingerbread and having a new screen asking which country and provider I had. Can anyone else do step 5 with ICS?
1. Go to Dialer. Dial *#*#4636#*#*
2. Go to Phone information. Choose the preferred network to
"GSM Auto PRL" or "CDMA Auto PRL" or whatever you have.
3. Scroll down, deactivate and activate Phone Radio.
4. Press Menu button.
5. Select Phone frequency, then choose your country.
6. In the previous menu push the Home button to go back to Homescreen.
7. Reboot.

I have tried flashing several different radios with no luck. I did find that I did not have any APN settings so I found the APN settings for my provider (http://mobile.free.fr/faq-config-apn-autres.html) and now I have EDGE .
Since I can only have one APN configuration selected at a time how do I configure the MMS to work? Will configuring it under a new configuration work or do I incorporate it into my current configuration.
And of course I still can't get that blasted 3G to work.
Any help would be appreciated!

Question Pixel 7 att preferred network type question. Help much appreciated

Under *#*#4636#*#* my preferred network type on my pixel 7 pro from att is nr/lte/wcdma. Does that seem right . I've changed it to be/gsm/wcdma and it literally defaults back to the nr/lte/wcdma.. help appreciated
And what happens when you insert another carrier's SIM card or remove the SIM card?
Well why would I put a different sim in a carrier locked phone first of all
Secondly what would removing the sim do?
NR/LTE/WCDMA (aka 5G/LTE/3G) is fine. If you don't want 5G, change the "Preferred network type" from the SIM settings, or choose LTE/WCDMA (aka LTE/3G)
Thanks everything that I tried in the dialer defaulted back to nr/lte/wCDMA no matter what I selected . Is that a glitch or something? Nothing I selected "stuck" lol.

What are you trying to achieve? Are you trying to set LTE as the preferred network type instead of 5G? If so, do it from the SIM settings. That will switch it correctly.
Not trying to achieve anything . Went in there to check some other settings and thought it looked "off" is all

IF your SIM settings has 5G as the preferred network type, it will default to NR/LTE/WCDMA. This is the correct value for 5G/LTE/3G. If you select 4G as your preferred network type in the SMI settings, the value will change to LTE/WCDMA which corresponds to LTE/3G.. The SIM settings will likely override anything you select in the *#*#4636#*#* settings
Ok thanks ...

I was under the impression from reading posts in the 6 forums that AT&T was blocking the ability to change the preferred network type in settings so OP may not even be able to do that.
