I have a problem with setting android to only use 2G networks. I can tick an option under settings "Use only 2G networks" but after i leave the settings menu it gets "unticked" again threfore i,m constantly on 3G which wouldn't be a problem but in the areas where there is no 3G signal android loses signal and wont connect to 2G network. I can turn off 3G under winmo tof orce android to only use 2G networks but it takes time. My question is can anyone successfully setup their android to use only 2G networks?
Same Problem
I´m having the same problem and for me it´s worse because it drain my battery really fast (don´t last more than 4 hours).
Could somebody please fix it as soon as possible because this way is really difficult to use android as main OS.
When I put a Sim Card that doesn´t have 3g I don´t have this battery problem.
I hope somebody could help me with this problem.
could someone please look into this? 3G kills my tilt realy fast too. this is the only thing stoping my from using android as my main os.

Try this:
$ su
# rwsystem
# nano system/build.prop
Find the part that says something about default_network=0. Try changing it to 1. Save with dpad-center+x, then y and enter.
# rosystem
Restart your phone to have it take effect. I'm currently trying out the value 3 which is "use GSM or WCDMA, whichever provides the strongest signal" and it seems to work better for me. Before I often had switched to Roaming after calls and somethings loosing connection completely, but I have only tested it for a short time so I'm not 100% sure if it helped or not.
Next release will include scripts to change this and some other things easily.
Oh, and the value 1 is supposed to be "GSM only" so it might help.

Kalt, should we change this "ro.telephony.default-network=0"? to "1"
If so, it didn't work for me . I'm still on 3G.

Yes that's the one. Well, getting information about the settings in build.prop isn't easy. I'm don't know if the information I found was a fact or just a guess.

HELP!!!
I have tried everything here and still no 2G. I love android but battery life sucks. There has to be a way to force 2G all the time. 3G is great but if batterylife will suffer so badly I want to turn it off perminently. Does anyone know how to do this? I'm using VaniljEclair RLS7c and I have been messing with the scrips in the update and still nothing after reeboot.

I have tried everything too with almost all builds (1.6 2.1 and 2.2). My opinion is that ro.telephony.default-network command do not work on Kaiser. If ro.telephony.default-network is removed from build.prop nothing happens. Maybe TelephonyPprovider.apk is something to do with 2G 3G switching.
Bump... Please someone help us!! There has to be some hack we can try.
Please help us!!!
I agree,
Would be great to be able to force certain networks. If you look at the power usage/ per network the faster the network the more power it consumes. I'd like to be able to by default use the low speed and switch it to fast when I'm really using the phone. My EVO has a 4G widget switch. If it didn't the phone would be worthless to me as 4G in my area is not great. 2hrs 4G on (with no 4g network) = -40% battery... Love to do the same for 3G as that would save "about" 20% more battery life alone. I might get a whole day of use without charging...

looks like this is only for 3g-2g data connection.Discussion is about GSM -CDMA network

As far as i know apndroid disables both 2g/3g connections and we only need to block system from using 3g connections leaving 2g still connectable.
Has anybody seen this before?

I get the settings, but the problem is that I can't choose any - no matter what I choose it stick to "Unknown" type..

I've tried that a while ago and it didn't work for me.
I've bin going thru htcgeneric-ril.c (source of libhtcgeneric-ril.so), provided in another topic and noticed this lines:
Code:
switch (rat)
{
case 0: at_rat = "1,2"; break;/* Dual Mode - WCDMA preferred*/
case 1: at_rat = "0"; break; /* GSM only */
case 2: at_rat = "2"; break; /* WCDMA only */
}
Could there be a solution lurking in those lines to ongoing 2G/3G switching problem on Kaiser devices with Android?
Those look like the settings from the phone information screen in testing, it's certainly the right area to be looking in.
Question: who's gonna be brave enough to hack htcgeneric-ril.c and recompile that lib?
I already asked n2rjt to do it, if it's possible - still waiting for his reply.

recently got my HTC Hero I am with Optus (Australia) all the time when it says 3G at the top of the screen the connection is terrible (speed tests are slow etc) however if that says H i get more bars and super fast connection
if i use just 2G its just plan slowand not usable for VOIP etc
I am wondering is there a command i set to say only use H which i am guessing HSDPA?
Thank you
OzJames
The phone automatically uses the best connection available to it.
If it's not showing H, you're not within range of HSDPA service.
check on the market and download an apps called "any cut".after u install it open it and create a short cut for phone info by tapping on create a shortcut then choose activity then phone info by scrolling down to the options that says phone info.now go back to the short cut created called phone info and open it and scoll down to set preffered network type.the phone has a default settings to wcdma preffered.tap on the pull down menu and choose wcdma only and press on the back key twice to go to the home screen .this keeps your connection on 3g or H but will reduce in areas you cant get 3g or H.WHEN YOU GET THESE CONNECTION PROBLEMS CHANGE IT TO GSM ONLY.hope this helps

I don't understand, what is the purpose of doing this?
Like I said above, the phone will always use the best connection available (unless you set it otherwise in the options). Why set it to WCDMA only?
If you're in range of HSDPA service, the phone will use it.
Maybe I'm missing something, but this makes as much sense to me as asking how you can download more RAM to your computer

actually it would be like setting the computer up that it would only use a fast internet connection, and if it is slow not to use it at all. would be like connection fast -> page loads, connection slow -> page is not loaded at all.
hs(d/u)pa is an extension to the umts standard. if it is not available in the cell you are using there is nothing to do about it. if you have gsm with edge availabe that might even be faster than a bad 3g/umts connection, but that depends on many factors.
Works perfectly thank you
Its much more stable now

Heya, I'm also on Optus in Australia. The problem thatyou have described is actually really common with Optus users. Optus has way too many customers and have overloaded their system. A easy work around for a more stable connection is to change your APN from internet to yesinternet hope this helps.
Check the thread pages to see results from other users who have had much better results than the ones I got.
This solution was discovered while I was checking out the CDMA Hero forum, so I don't take credit for discovering the method.
http://forum.xda-developers.com/showthread.php?t=651848&highlight=cell+standby
Goto dialer and dial *#*#4636#*#* (DO NOT press send) wait a second and you will get the test menu.
In the test menu choose 'Phone Information'
scroll down and choose on the first drop down - GSM auto (PRL) (for high speed data) or GSM only (You may get 3g if not use GSM auto (PRL))
Back out to test menu then back into 'Phone information' to see if it sticks (if not try again) then back all the way out.
You might want to reboot, but I found the settings worked straight away.
Edit 3 - I don't take any responsibility for step 6 - 6) Try other settings on the dropdown if you are brave as I don't know the consequencies of using settings like "EvDo only" and "unknown" as they may be better depending on the way your provider provides information.
Edit 4 - can't seem to select the other settings like EvDo and unkown anyway.
Edit 3 - TBH - GSM auto (PRL) is working for me with HSDPA and I will try
(PRL) instead of GSM auto (PRL) <- edit - previously it mistakenly said GSM only
the CDMA and WCDMA settings later to see what other effects there are.
This way I managed to get 5½ hrs and only lose 10% battery (GSM Only)! (Edit 3-) Slightly more drain with GSM auto (PRL) but still better than before.
Previous to this I lost 35% in the same amount of time with the same use (sometimes even more when I didn't even use the phone all night).
Hope the devs can make use of this (maybe mess with other settings in there to improve battery more.). I did notice that the GSM auto (PRL) uses a bit more battery than GSM only, but that is to be expected.
Edit: Actually you might need to set it on each reboot, not sure, the settings stayed when I rebooted
Edit 2: When you change roms (or re-install a rom) you will need to do this again, but should stay after a normal reboot as it does for me.
============================
Results:
Your results will vary depending on the rom, but it should improve battery performance - some have had better results than me using this.
GSM only <---- If you don't get 3g with this it is the same as 2g setting then use GSM auto (PRL) if you want faster than 2g (as some people are getting 3g on GSM only - I will investigate. (if you don't use internet or don't need fast internet)
5½ Hrs - lost 5% Battery - This one is same as running 2g as you don't get HSDPA, but using Opera browser makes browsing fast even using this. If you want Higher speed data use the one below.
GSM auto (PRL) <---- Recommended if you want High speed Internet and save battery
1:40am to 2:00pm (12hrs 20 mins) - lost 40% battery with moderate use a bit of surfing at HSDPA speeds, a few calls and messing with a few apps. Other people have had even better results than me though, so I might change my rom and try again. (I would usually about this amount of time I would have lost about 70-75% - and yes it was that ridiculous - I had to find something to stop this).
" WCDMA Only"
2:06pm to 11:37pm - (9hrs 31mins) lost 46% battery again moderate use and a reboot
This one might be useful if you live in a place that has low GSM signal like the chap in post #10 as it does give HSDPA - but this is only a suggestion as I cannot test it in Iceland. Anyway
" WCDMA preferred"
6:02am to 2:51pm - (8hr 49mins) lost 41% battery this time with less use that the WCDMA use and no reboots.
=============================
Conclusion: (For me anyway)
SO my preference is GSM auto (PRL) some people have got some excellent results with this. You may, however, require one of the other options depending on your service provider signals.
===========================================
EXTRA OPTIONS :
Other settings you can change: (You may have tried this already)
If you don't get GSM auto (PRL) then if you press the menu button on your phone in the 'phone information' page and select 'radio band', you may be able to change it to Automatic or one of the other settings and then you might get GSM auto (PRL).
Available Radio Bands * You may get others depending on the radio you have installed, but I haven't confirmed this*
Automatic
EURO Band
USA Band
JAPAN Band
AUS Band
AUS2 Band
There are other settings there that I haven't messed with, maybe someone with more knowledge may be able to help
Thanks to those who found out what PRL stood for, I will try to update this info in the instructions soon.
========================
I think the reason this works is because it prevents the phone from constanly looking a round for various networks types as it I did notice that the Cell standby time is always high and using this method the cell can standby without constantly searching for a signal thereby wasting power. ALso using this method my "Awake time" is a LOT LOT lower than my "Up time" - about 1200% less (is that right 12 times lower (Up 12hrs - Awake 1hr) ?) - before this the two times were most of the time the same and some times slightly lower. - I'm sure someone will let me know if this theory is incorrect - and I'm open to and welcome that.
This is my experience you can read other peoples who have achieved a lot better than me, and I'm glad I spotted this and let you guys know. (Those who are saying that you've known about this test menu thanks for letting me know that you knew about it before, but a lot of other people didn't know about it. ALso I don't think people have used this as a tool for increasing battery in the GSM section of the forum. As I mentioned at the top of this post I noticed it in the CDMA section as a way of increasing battery performance. - credits to them for thinking it up in the first place.) -
All I am saying though, is to test it out yourself.

Like I said in the first post GSM (auto) PRL gives you 3g/hdspa but not as brilliant battery as GSM only, but is better than before.
I am now unplugged from fully charged. Will report back in the morning and throughout the day to let you know if this works.
About PRL, here's what some telecom website says:
The term PRL actually refers to file stored in your phone. This file directs the phone to find alternative networks to operate on when the primary operator cannot be reached. Updating the PRL will store in the phone which are the most up to date, current networks to operate on. In order to operate on another carrier’s network your primary service provider must have a roaming agreement with other carriers.
Almost all phone carriers, such as Oxygen, Locus, Cingular, Verizon, etc. have roaming agreements with other major service providers.

So I guess it's useful?
Suppose so.
I am on a fairly small operator in Iceland and my phone started roaming when I did this.
I lost 3G connection and went over to Edge...
Switched back to the WCDMA Preferred.... My provider has a little limited coverage but has no roaming charges on the GSM network.
Any ideas what setting I should use for my phone other then WCDMA preferred
Yea mine is on Wcdma preferred when i go into it. Im on t-mobile uk. Ive left it for now as dont really know how long this battery is lasting. Going to give it a few days to see an average

I'm on T-Mobile UK and GSM auto (PRL) gives me 3g/H and GSM only gives me gprs. Like I said, both give me loads of battery time (GSM auto PRL is a bit less than GSM only though).
Interesting, I may have done this accidentally a few days ago...
I just checked and it was already on GSM auto PRL, I'd changed this in my build.prop last time i was fiddling:
ro.telephony.default_network = 0
I thought that would give me wcdma preferred but apparently not...
I'll have done your tutorial ... will wait till end of day what happens
Definitely helped battery life.
Thumbs up!
In fact i can be wrong, but this tip only disable 3G access... only GSM and Edga.. so it save some battery for sure.. but you will navigate slower if you have a real 3G or 3G+ access.. am i wrong ?
Ciao

Surely this does the same as the button in the options to just use 2G?

Correct me if I am wrong, but isn't HSDPA faster than 3G?
source: http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access
in which case you would get your faster browsing using GSM auto (PRL) - giving you HSDPA. I certainly get a H showing at the top of the screen while browsing and it isn't constantly connected when I'm not browsing, which it was doing (connecting and disconnecting all the time) before I chose this setting, and thereby my battery life was extended a lot.
Edit: Just try it - if it doesn't work just put it back to your original setting, it has worked for me - There are other settings in there but I have not tested them out yet.

It may be, but not if you choose GSM auto (PRL) - also make sure you have the correct APN settings from your service provider. I did notice that the standard APN's on the phone have always been a little different from the ones on the T-Mobile UK website.
This is not a fix for the battery issues in 2.1 roms, althought it may help as 3g doesn't use the same amount of battery as 2g. But i think everyone knows that anyway. Much easier having the 2g/3g toggle on the home screen and changing it to 2g only when you are not using the web browser etc
ps: before people say other wise this menu has been known for ages and every rom I use is always on GSM.
Hey I just came from Galaxy S and there is a way to disable Hsdpa in there which improves battery life amazingly....
I was wondering if there is a way to do that in Desire? (for my city 3g speeds are faster than hspa for some reason)...
Also is there a way to select which band the phone is connecting by 850 vs 1900 ... or to see what it is using ?
any help would be appreciated
It's in the settings someone in network
There is also a widget to totally disable mobile internet which I use to save battery
Sent from my HTC Desire
Go to Settings > Wireless & Network Settings > Mobile Networks...
That's pretty much what you can do with the Desire as far as mobile networks are concerned. GSM phones normally switch to different frequency bands depending on where they are located and in the Desire I don't think you can select which one to go for (besides it's an unnecessary feature in my opinion)...it just does it on its own. Maybe there is an app around that let's you do this?...
As for viewing which band you are on....you can't do it on a standard ROM but there might be custom ROMs or an app that let's you do this.
Update: Some apps that might interest you => 4G, CDMA, GSM & Wifi Map Viewer from Sensorly.com
=> Open Signal Maps Beta from Staircase 3, Inc.
=> Antennas from mpoly
=> Quick Settings (maybe..)

Ah, so you have a Galaxy S.....unfortunately, this is a HTC Desire forum, so it would be better if you posted this in the Galaxy S forums. You may not find the answers you are looking for here as this forum mainly handles a different device to the Galaxy S.
What I said before is only applicable to the HTC DESIRE. I thought you switched to a Desire when you mentioned you came from a Galaxy S, but I was mistaken. The apps I mentioned as mainly for monitoring the 4G, 3.5G & 3G (i think 2G too) coverage. If you are looking to switch between them (i.e. turn HSDPA off and turn 2G on) I am sure there is a way to do so...on the Desire this can be done through the Mobile Networks settings...
And no, I'm not familiar with the Galaxy S....
no i had the galaxy s... (i posted that for reference as to how its done on that)...
and ya those apps just toggle just 2g vs 3g...
im looking for a umts vs hspa toggle... (3g vs 3.5g).... because umts takes way less battery than hspa does...
tried to mess around in the band setting screen but couldnt find anything
SOLUTION
what you need is to edit /system/build.prop file
here are my settings:
ro.ril.hsxpa=0
ro.ril.gprsclass=12
ro.ril.hsdpa.category=1
ro.ril.hsupa.category=1
after doing the and couple?... of restarts H icon changed to 3G and it really does save battery significantly and speed is pretty much enough for browsing or email
would have thought if battery life was vital then you'd disable data completely tbh
This is somewhat network dependent. Here in Sweden I know of one network that will have you at HSXPA (H) as soon as it is possible. My network on the other hand will set to 3G when WCDMA is detected and set to H only during data traffic.
And then G if only GSM is detected.
I disable data via widget if I want to save power even further. Not that it has that much impact. There is a setting under wireless and network > mobile network at the bottom : ativate mobile data (this is translated). This setting will force the data connection to be active even if unused. You have to experiment here what setting is best for your network. On my network, if I remove the tick here (data connection will let go if not used and reconnect when needed) my battery will drain quicker. Providers with other policies might give different result.

Thanks! Very useful! For me it was only necessary to change the "ro.ril.hsxpa=0" line, then do a couple of restarts (to make it clear, a single restart wasn't enough, HSDPA was disabled only after the second restart for me).
Hello guys,
I need some help here with my DHD. My serious problem is about its signal. I am in my home and i am talking on my DHD, but sometimes it loses the signal. In my house, the signal is very good, not always at 3G but at 2G it is always at full signal.. Although, it sometimes loses its signal and my call is closing.. By the way, to be more clear, when my call is closing i check the signal, and i see it to be full... At this step, when i am checking about the signal, sometimes i see the signal to drop down to zero, after 1-2sec.. But the other times it stays full.. But in both of these cases, my call is closing many times.. What can i do to solve this problem, anyone knows?
Thanks, and i hope to help me with this.
P.S. Sorry for my bad english guys And one more problem that i have is that my DHD few times, it lags, stucks, dont know how to say it, and in first case it unstucks afters 30-40 sec, or in second case it restarts..
AFAIK, the gsm antenna is located in the bottom cover that the sim and microsd is hidden behind. If the contacts inside dont make a good connection you will probably get lost reception from time to time. You could try another cover, or bend the two gold coated spring contacts near the simcard very slightly outwards to make the connection more reliable.

I tryed it mate, and tnx for your reply. But today in the morning, when i was talking on the phone, my call closed 4-5 times in a 20min call.. Dont know what is happening, but maybe anyone of you guys knows another tip to help me? Maybe any change on the software? And by the way, my phone had in automatic the choice about 2G/3G, but i changed it some days ago only to 2G because in my house the 3G signal is not so good always, and if it loses the 3G signal and it needs to change to 2G, the call is closing for sure..
I have the same problem with my DHD, I live in an area where the 3G signal is crap. I found that when running CM7 you can switch off the 3G and just use the 2G which helps. If you using a sense ROM you don't get that option which is a pain, so I'm sticking with CM7 for the time being until someone produces a workaround for the other ROM's.
switch off the 3G and just use the 2G which helps.

I have the same problem with my DHD, I live in an area where the 3G signal is crap. I found that when running CM7 you can switch off the 3G and just use the 2G which helps. If you using a sense ROM you don't get that option which is a pain, so I'm sticking with CM7 for the time being until someone produces a workaround for the other ROM's.

You can swith off the 3g in Sense ROMs, press Menu > Settings > Wireless & Networks > Mobile Networks > Network Mode change to GSM Only not GSM/WDMA Auto (WCMDA is 3g)

Oh OK, that sounds like an old sense ROM. I used to have this problem when I first got my phone. Im using Android Revolution which is based on the latest Gingerbread.

Try your sim in another phone. If the signal is still bad you should try contacting your network operator and ask them if there are any faults or if they can do anything to improve your signal.

No sense is like CM7 (Cyanogen Mod 7). They are as close to standard google android with added features. Standrard android is found on googles own devices like Nexus and Nexus S. Although CM7 is based on AOSP (google it). Sense has a different (rosie) launcher and added extras included such as widgets, Icons, and other extra HTC only features. Look in the Desire HD andorid development thread for different ROMS with sense no sense.

I was using some times another phone but i didnt have this problem same as i have it on my DHD. Yeah, maybe i had it few times on my other phone but occasionally, and not so many times like these on my DHD.
I had the same problem. I had to order a new sim because my sim card was old and apparently wasnt very compatible with my DHD. I'd suggest getting a new sim from your service provider
Hmm leaked from my thumbs through my mobile device....

When u are saying that your sim card was old, how many years do u mean?
Cause i think that i have bought it about 4years ago... You think i have to ask for a new sim card with the same number or what??
I'm running my Captivate glide on Orange network (device is unlocked).
I rooted it following all the steps shown in http://forum.xda-developers.com/showthread.php?t=1378082 (BTW, works great thanks).
I kept AT&T rom, but issue happens also with Rogers rom.
This happens only on 3G/3G+ connections.
WiFi works great.
The issue looks quite simple: data connection drops (very) often.
No more email push notifications, ...
Have to go to Settings > Network > Airplane mode : switch it on and then witch it off to get data connection back.
It is not an operator issue. My other phone(s) are using the same and data connection works.
Is this a radio rom issue ? Is there a fix ? (didn't find a thing related to that issue).
Anyone having this issue ?
Depends on how strong your network is, I have experienced this a few times.
I keep getting this now that I have had more experience with it, anyone else experiencing random sharp drops in data speed/connection?

Well, I have 4 out of 5 bars... Signal looks strong enough to me.
If I use the same SIM card in a HTC MyTouch 4G slide => Works great, no data connection drops at all !
Looks like it depends on what programs are running and using the data connection:
- email push - connection last long enough.
- when I'm running Bejive (IM) - connection last a bit less (before the 1st drop).
- when I add Skype & LoudTalks : almost every 5 minutes connection drops.
I also noticed that after a voice phone call, sometimes data connection doesn't (cannot) restart by itself ...
Here is an idea :
Is there a way to tweak Operator connection like it can be done with HTC phones : GSM + CDMA, CDMA Only ?
Because when you switch the phone to CDMA only, it uses different frequencies and allow to keep data connections while talking on the phone.
Didn't find that option in Captivate Glide settings ...

Settings --> Wireless and Network --> Mobile Networks --> Network Mode
Didn't make a difference for me using HSPA only.

I just checked ... I don't have the "Network Mode" option in "Mobile Networks" section.
I have Roaming, allow data connection, APN, ... but not Network mode.
Weird...
I checked the operator info. Nothing out of the ordinary there.
I'm stuck ...and it keeps happening. No solution for now.

Maybe try flashing the Rogers kernel and ROM since that's what I have?

Already did that, but that was a few days ago when looking for the WiFi tethering feature ...
I'll flash it back to Rogers kernel & ROM and test.
Update: Flashed Rogers rom.
Good news is I now have the Network settings back. (AT&T rom is not the right one, for sure !)
Data connection last longer. But the issue is still here.
Still investigating...
Anyone else having this issue ?
the day before yesterday, I went to the copier room in my school and stayed for about 2 hours (too many copying). before i get out, i have no signal (mobile network not available). I need to go out to have signal back or reboot.
It happened again yesterday on the exact same location, I'm going to be there again now.
I believe it might be location wise....in my case at least.

I checked, looks like it is not linked to a specific location. I've been travelling and issue kept occuring.
Once data connection is ok, it usually stays up for 2 to 5 minutes, then drops.
"4G" symbol is still displayed - but no more data connection. Web pages not available in browser, no email sync, no more IM, ...
While data connection is down, Cellphone still works, WiFi as well.
It may be linked to an APN issue ... Or definitely a Radio ROM issue.
I'm running Baseband I927RUXKJ5.
Anyone else having this issue ?
When I got the phone the AT&T rep told me there was a known issue with the phone dropping down to lower data speed. He told me if I experienced it to get a new SIM card. Doesn't sound exactly the same but maybe try that?
