wcdma only? - Galaxy S III Q&A, (US Carriers)

When I had my nexus one and nexus s I could create a shortcut with bettercut called phone info. It took me to a screen that allowed me to select GSM/wcdma or wcdma only along with a few more options. Where I work it switches from "4g" to edge constantly which I'm sure is draining the battery. I want to lock it to wcdma only but can't create the same shortcut. I'm not sure if it has a different name on gs3 or if the option just isn't there. Any help would be appreciated.

Found an app called network in the play store took me to the device info screen and I was able to select wcdma only.

Galaxy S2 Att - Use GSM only

Hi
I just got Galaxy S2 att but I am in Europe, and since I don't use phone only for calls & sms I wonder if there is an option to permanently set phone to use GSM only?
I know the trick with ...4636... menu, where I can set to use gsm, but when I restart my phone it goes back to umts again.
Is there some hack to open that menu in "mobile networks" or should I use international rom?
I'd find what db it edits when you do that then make init.d script to make that edit every time you boot.

can you explain me how to do it?
thanks
The phone should technically revert to edge. You see the phone by default is set to 3g prefered meaning in these situations in which roaming in another country and the frequency bands do not match or cannot find 3g in the area that in which your phone uses "att". It would in this case revert to a lower spectrum until it finds one your phone uses. So in this case it should be automatically reverting to edge when you hopped off the plane, boat, canoe, whatever.

I have 3g signal but it's love, and i have seen posts that 3g uses more battery, so since i don't use data i want be able to force phone to use gsm only.
I have tried *#*#4636#*#* but it won't switch to gsm, stays at 3g.
I got the same problem, dude. Still find no way...Using UNNAMED 2.2.1...
You can check you wireless setting menu--> Mobile network to see if there is an option for you to choos Use 2G only.

unfortunately there is no option to choose 2g because that menu option is gray, i can't even open it.
i am also using unnamed 2.2.1
Try *#2263# and in menu choose gsm only, then it will use only gsm network. Bu again, when you restart the phone it goes back to umts

[Q] Changing preferred network operators?

I was wondering if there is a way to permanently select a operator?
My network operator (Play) allows free roaming on other carriers inside the country (Orange, Plus, T-Mobile)
I get horrible signal in my work and at home with my "home" carrier and I always roam on one of the others. But I have to manually select that network and every so often I get a "refreshing SIM" message and it switches back to my home carrier (Play) which then gives me 0 bars. I then have to go into settings and select a roaming partner all over again (and this happens at least 2x/day)
Is there a way (either by editing a file/deleting a file or some app) that I can force my phone to only and always roam and not connect to my home network?
pssss.... there is top secret solution... when you will be in the roaming range, go to mysterious hidden menu, called: Settings.
Then, in the section called Network, go to the Mobile networks sub section.
When you'll be there, you possibly would find the most hidden secret feature: Network operators selection mode.
when you will enter this one, you can choose between manual and automatic operator selection.
Please do not populate this advice, is for highly advanced users only, and because of that it is hidden so deeply... in the secret document called: Owner Manual.
haha funny. But if you read my post you'll see I do manually select the network, but it still kicks it over to the home network every day.
if you unticked auto mode, it should not switch back...

I did but it clicks back when there is some "refreshing sim data"
I looked more about the operator and it seems others have this issue with their android phones. It seems the operator forces a network update (I guess to cut down on their fees they pay to the other providers)
So my option would be somehow removing the home operator from the list of operators that the phone can connect to (if there is such a list) or some app that forces to only go on certain networks that I pre select. Nothing is set in the network providers as auto, everything is on manual.
Or of course change providers (but I'll have to see what the canx policy is)

[Q] VZW Google Edition ROM 5.9 NO LTE

Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.

[Q] prefered network? hidden menu

Was just curious about network settings. Under the hidden menu my prefered network is set to wcdma prefered. Is this the best setting to use? This will still allow lte network correct? Thats what mine is set to default and if I try to change it it goes back to wcdma automatically. If im thinking correctly wont this automatically pick the fastest network available to me? Including lte? I camebto this conclusion because I do get the 4g symbol when Im in the signal area for lte. Also what kind of speeds is everyone getting with LTE? THANKS for the help! Just want to check and make sure this setting isn't preventing me from getting lte speeds.
The menu setting that you see is to only use one of the the technology's and the bands those the technology's uses to connect to the network (e.g. gsm,wcdma)
BTW. None of the l9s have LTE the l9 2 might

Cannot force 4g only option.

After getting into engineering mode by dialing *#*#4636#*#* And changing the preferred network to LTE only. It stays in 4g for a minute and changes itself back to 3g. Is there any way to force the LTE mode.
I guess it must be one of the ****ty work done by Oppo in the name of enhancing network experience.
There is a solution for you
1.Atfirst clear all your recent apps
2.Open the settings and mobile networks then tap on prefer network type.tapping on that it will show you the network types.keep that page and tap the home button
3.go to dialer and type *#*#4636#*#* and select lte only..
Some conditions works here... engineering mode doesn't work if the settings app not running in background....after selecting the lte only in engineering mode then go to settings in that page of network mode,you can see all the three options will be unselected..It is not so easy as you think...many t&c applied here
Its works like charm
I wanna tell you one thing.
Man you are a fcking legend.
Just got my Realme 5 pro and *#*#4636#*#* doesn't work even if the settings is running in the background. I just want to lock it on lte or lock the frequency band to lowest frequency available here in the Philippines so I can play without lag even inside our house (more like a cave). I was able to do it on my previous phones so I'm kinda starting to get disappointed with this phone.
