Hello.
Hello.
I am currently using the The Ultimate ROM, when active data I always get in the notification bar E data, but when I activate the 3G signal dies completely:crying:, I mean to activate 3G data not working. That is problem with your machine or ROM?

...3G works fine for me :S
Go to setting and disable 2G networks

Check your APN settings and make sure they're correct, my friend on the Ultimatum has no problems with his 3G so it may be that your APNs aren't set up correctly

Does 2G work on Telus with Milestone?

I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.
Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.
Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.
Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.
Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Is this not the same then as just shutting off data?

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.
I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.
The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.
ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.
I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!
I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!

Any way to force EDGE over GPRS?

Can anyone tell me if there is a way to force my phone to stay on EDGE. I have good EDGE signal but it keeps jumping to GPRS.
Thanks
I don't have my note yet, but in SGSII. If you go to settings>>wirelsss and network>>Mobile Networks>>Network Mode, Choose GSM only, it should always stay in Edge.
It worked for me.

this will prevent you to join 3g, if u select gsm only, it will disable 3g.
but i dont know you can select between edge n gprs

well I'm using a unlocked GNote on Tmobile so for now no way getting 3g anyway but in a area where I have full bars on Edge sometimes it switches to GPRS which I'm trying to prevent.
I think it depends on network, n even i dont believe it have relation with nwtwork bar. You will get edge or gprs according you are connected with network. So it is metwork dependent. I dont think you can change it manually, as both are comes under 2g. We can chose 2g/3g, but afaik we cant select subtype.

sucks for me
you can try with this hidden menu, in the phone dialer input:
*#*#4636#*#*
first option, about phone, slide to the bottom and you will see network connection options, choose CDMA only to force EDGE, also you can choose more options than in the normal menu, don't modify anything else in this menu

CM 10.1.2 2g jumps to 3g problem

Hi
all fine on CM10.1.2, except the fact that I want to use 2g only for battery saving, and after switching to 2g only, the phone autoswitches back to 3g after a variable period of time (30 min - 1 hour). During this time, the phone is on 2g as required. I have factory resetted, formatted all the partitions, odin-ed android 2.3.6 and after that CM 10.1.2 from CWM; so all clear, but the problem with 2g/3g remains...
Any fixes please ?...
Thank you!
think you can change the settings in service mode, not sure what the code is... also you have to type it into the stock dialer to access it.
tnanks, but I want to manually and easy switch to 3g when I want. Anyway, I didn't find any working codes for secret menu...
goto "settings" then "wireless & networks" then "moble networks" then click on "use 2G network only" also select "GSM/UMTS Network preferences" and select "GSM only"
I don't find GSM/UTMS option... when I click 2G only, after a while it uncheck itself and switches back to 3G.

I have temporary fixed it by using juicedefender. When not on wifi, it goes on 3G, so it's ok.

[Q] is there any way to keep the phone from using LTE?

my phone is unlocked and i use tmobile service..
they just switched on LTE in my area.. and its working great.. i assigned a new APN (fast.t-mobile.com) and i get upwards of 18Mbps.. but..
in my house.. the LTE signal is 1 bar.. most of my calls go straight to VM and i sometimes dont get texts for hours..
in my house the 4g signal which was the default before is 3 to 4 bars.. i never had a problem receiving calls and texts when its on 4g.
so it seems now they have LTE service the phone favors that no matter what the signal is..
i cant find any options in the settings to turn off LTE and just use 4g.
i guess you can disregard this question.. i installed CM10.2 and it has the option to only use WCDMA instead of LTE..
this fixes my issue

the CM10.2 has 3 options.
WCDMA/LTE

[TOOL] [v1.0.6] LTESwitch 2G-Auto-LTE for Nexus5/6

1) You can switch mode by clicking the button in notification : GSM for GSMOnly, AUTO for GSM/LTE Auto; LTE for LTE Only
2) There are some Auto modes : switch to GSM when WiFi connected; switch to GSM if the LTE signal too poor and so on.
You can find the settings in the main activity
App link in Google Play : play.google.com/store/apps/details?id=com.howui.lteswitch
switch to GSM when WiFi connected... is a nice one
@howui , can you add an option to remove the app from status bar ?
It switches data off and 4gv to 2g very fast but toggle data back on does not work
I have to manualy do this in settings

It should be enabled if you want to switch to LTE when mobile data network connected
This feature is not tested enough , so I make it disabled as default
how to make mobile data activate & switch to LTE when wifi is lost?

No this feature by now,because that in general WiFi is free and Mobile Data Network is not free
It should take user action to turn on mobile data network
Forgive me for my poor english
no problem with your english bro but maybe you can consider activating mobile data when wifi lost as sometime the user did not notice wifi lost then will have many missed notifications.
thanks for reading
maybe you could ad a timer like when disconnected from wifi wait 60 sec then enable data + 4g
Hi,
Haven't got the chance to test this app but can it:
switch to 2G when connected to wifi
switch to 3G/LTE when wifi get disconnected
but this without enabling/disabling mobile data etc?

I think there's no need to use this option since the phone automatically shuts data connection off when connected to wifi.
Go to settings - about - status - sim status and you'll see that "cellular network state" switches from connected to disconnected, independent from the data switch in the settings.
Other than that, this works perfectly for me. At work I have really bad lte signal but I have wifi, now it goes to 2g and the signal bar goes up automatically.
Can you explain why it needs all these permissions?
And is this open source?

Hi there may I ask for your expertise in guiding me how to change build prop to default Set Preferred Network Type to LTE / GSM Auto (PRL) as I am using xt1103 & the default is LTE / GSM / CDMA Auto (PRL) but I don't have CDMA in Singapore. Many thanks

Hi, FYI : https://forums.oneplus.net/threads/4g-lte-issues-build-prop-edits-fixed-it.57071/
For long time I am not on Android Rom work, so I'm not sure whether it works on nexus6.
The better way I think is set perferred network in android test settings
adb shell am start -n com.android.settings/com.android.settings.TestingSettings
