My carrier has bad 3G operation, whilst HSDPA works fine. The problem is that phone sometimes switches between 3G and H, and when it does switch to 3G, there is no internet until it swithes back to H or down to E. I'm almost sure that this is caused by carrier, and I can't fix it with firmware. So I would like my Tab to avoid 3G mode at all, while using H and E. Can I set it to do so?

Unfortunately, it's impossible, you can either choose "H" & "3G" with wcdma/umts or "G" & "E" with GSM in Mobile Networks. You can't choose to leave out 3G when it's doing H, cause both of them are under wcdma mode.
Of cause, if you leave your "Network mode" to auto, it will jump around gsm and wcdma when it see fit. By choosing it to run GSM mode only, will keep your network connect to "E"/"G(gprs)" ONLY; Or WCDMA for "H"/"3G" ONLY.

Is that possible?
Do you mean you want to keep the phone on 3G/3.5G only? Why would you need to turn off GPRS?
Yes.
Because sometime my connection is switching between H and G themself. When that happens the download will be interrupted.
Hmm that's weird. The phone shouldn't switch from H to G. It would go H then 3G then E and then finally G. But to lock the phone in 3G only type *#*# 4636#*#* and then hit phone information and then scroll down to where it says preferred network type and choose WCDMA only. That will prevent the phone from switching out of 3G but if you leave 3G coverage you'll lose data connection because it won't drop to E or G
thanks!!!! )
Hey good thread info.
But I was wondering,
How can I turn on 2G (GPRS) so I only have Edge or 3G or WIFI
The reason for this is, when on GPRS browsing it doesn't allow calls though to my Nexus One.
Anyone do you know the command? to turn off GPRS and leave ALL other's on please
I have already disabled fast dormancy using *#9900# code in my Note, but now my phone switch between H and H+ icon. When connection is idel, it falls back to H. If I browse a webpage, it takes more than 10 seconds to connect to H+. And yes, H has no data trafic avalable. That means I have to wait the phone to change to H+ if I want to browse the internet.
Does anyone know how to stay with H+ icon?
OMG no one knows?
I think it depends on your rom..

It depends on your Network and rom + modem u using.
Post the details here and lets see what the community here can find.
Data works fine on H. It certainly seems faster on H+, but, as you say, the phone spends so long finding and connecting, the speed is wasted. I'd be happy to stay on H myself.
I agree, it would be nice to keep to one. My connection jumps from 3g to H to H+ and even to E, especially when moving on a train.
I think it is network dependent
E - Edge 2G
H - 3G
H+ - 3.5G
When you set your network mode to auto, it searches for faster avaiable network. If you set it to only WCDMA, you won't get E, but i think there is no setting to select 3G/3.5G.
Another problem to select WCDMA is, whenever any place dont have 3G coverage, your network will lost.
In germany it is also other:
G - gprs up to 56kpbs
E - edge up to 128kbps
3G - umts up 384 kbps
H - HSPA up to 14 mbps
H+ - extended hspa up to 21mbps
But H+ is only active when it is needed and it is all carrierer depending. If i am on H+ i can se my battery dying

It is network related there's nothing your phone can do about it.
H+ is actually using the 64QAM modulation over the air interface which gives you 50% more throughput ideally than H.
3G is up to 384kbps
H is up to 14.4Mbps (16QAM)
H+ is up to 21Mbps
The above is the throughput on the lower levels, so at the application level you will get around 10% less (and that's if you are alone using the base station and your carrier is not limiting your throughput)
Everything that goes through wireless interfaces has to be shared between users. Therefore, the network has to manage valuable and limited resources to serve everyone and provide a best effort service. In order to do that, idle users or users below a certain threshold will be down switched from H+ to H (this usually happens due to radio signal conditions) and to 3G. After that it kicks you back to idle mode, so even if it says H, your actually not connected until a new session is triggered and based on your needs and availability, you are up switched to a faster channel.
Depending on each country and their marketing:
2G
2.5G is GPRS (G)
2.75G is EDGE (E)
3G
3.5G is HSPA (H)
3.9G (4G in the US) is HSPA+
4G is LTE
Fast dormancy is a new feature on 3G networks (not available in most networks yet) that improves your switching between different channels (H+, H, 3G, idle, ....) and it has a major impact on your battery life and the speed of establishing a new data connection once you are idle. This is also controlled by your network. Anyway, some people believe that turning it off while it is not supported by your network can help improving battery life. Which I don't think is true, since by turning it off you are forcing your mobile to ignore this new feature (and if it doesn't exist there's nothing to ignore anyway) and turning it off shouldn't have any effect unless it is active on the network and your carrier is not managing it correctly.

There is a short code for turning off h+ my phone would always time out when trying to connect to h+ so disabled it. And it works great now, can't for the life of me remember what the short code is though!

Is there a code to turn on H+ too? Because my phone used to show H+ but now it only shows H although I have not changed any settings.
Guys I have an odd problem.
Where I live, the signal on the HTC One switches erratically and constantly between H+, H and 3G. At every switch of course the data connection goes offline. It's driving me crazy.
Is there a way to force the phone to one of the three: 3G or H or H+?
Please see image 01.
I've tried going into *#*#4636#*#* but the choices baffle me (see image 02). I've tried a few of the available choices but it seems that 3G, H and H+ fall into the same category.
It's probably a dead end, I can't imagine what else to do ..... has anyone else had the same issue?
The 3G logo means it's on voice only, and H+/H means there's data incoming/outgoing. They're using the same radios and frequencies, it's more like an idle state when it shows 3G. 3G will still periodically go up to H+/H to check for any incoming data then goes back to sleep at 3G.
I have the same problem with my connexion. It is only stable when I have the "3G" symbol. I did not find a way to force "3G". It seems the switch to "H" is on demand...

It's normal behaviour, if you have a good H connection it will switch to this when there is data traffic but when there isn't it will switch between 3G and H
Guide: How to turn LTE off
Turning LTE OFF can be very beneficial to the end user. Turning LTE off can boost your signal and save battery life in areas of weak LTE signal strength. HSPA+ and EDGE signals travel further than LTE signals. At the time of this writing, AT&T’s HSPA+ network performs very, very well. Most people have switched to LTE. It is very easy to pull 10mbps down on HSPA+. Therefore, if LTE is congested you can try out HSPA+ (AT&T calls this 4G). Some people also like to force the device to LTE only; this way they don't get calls, but can receive texts.
1. Open dialer
2. Dial *#*#4636#*#*
3. Device information
4. Scroll down and then choose your preferred network type:
WCDMA Preferred = Your phone will prefer UMTS/HSPA or HSPA+. Will connect to EDGE if it has to. NO LTE.
GSM Only = If selected, your phone will only connect to EDGE (2G). You will be able to call, text, and use slow data.
WCDMA Only = UMTS/HSPA+ only. No EDGE, or LTE whatsoever
GSM/CDMA Auto= Will connect to either UMTS/HSPA/HSPA+ or EDGE (which ever one is available)
LTE/CDMA Auto = Will only connect to LTE and UMTS/HSPA/HSPA+, NO EDGE
LTE/GSM/CDMA Auto = Will connect to LTE, EDGE, or UMTS/HSPA/HSPA+
LTE/GSM Auto = DEAFAULT SETTING
LTE Only = You will only have LTE. You cannot make calls under this setting. Good for those who want data and text capabilities.
Hope this helps!!!

Will the change last through a reboot or does it need to be changed every time the phone is restarted?

Yes. For each reboot you'll have to repeat the above steps. However, I would rather do this, than have to take out the sim each time.

I wonder if a NFC task program can be used to program the sequence into a NFC tag so it can be easily changed each time?

Thanks! I switched from the default to WCDMA preferred and seem to have a better signal where I live (on a mountain).

Sorry if this is a stupid question but I don't want to screw up my phone. Which would be the default in case I want to turn LTE back on?

You will not screw your phone up, no matter which setting you choose. LTE/GSM Auto is the default setting. Once you select your preferred network it will not stick once you reboot your device anyway.

Probably leaving it on automatic.

Cannot turn off LTE with above instructions
When I try to follow the instructions, I dial the number and a pop-up appears with "USSD Code Running..." then it closes and a new pop-up appears saying "connection problem or invalid MMI code". I have tried to make this call from various areas with better connections than in my house, but still to no avail. I'd really like to disable the LTE because it is only strong enough to constantly force changes from 4G to LTE and back while massively draining my battery in the process. Any advice?
I upgraded from S3 to S5... In Out location there is one LTE tower.
When at office which is bit far from LTE tower, It only connects to LTE and due to congestion i always get 0.2 mbps only..
But When i had S3, it will switch automatically to 4G(HSPA+) at office and at home or shopping it connects to LTE.
So I called ATT support and they said its due to network congestion and they switched to 4G on their side.
So now its always shows 4G only no LTE but speed are good like 8 to 10 mbps..
I tried the steps in post1 and it shows WCDMA preferred... Is this what they modified remotely?
Try Intelli3G everyone, you have to install Xposed framework and then install it but this app is amazing for convenience.
I tried changing to LTE option its not allowing. I can change to other options other than LTE.
Any idea.. Is it controlled by AT&T?
I called ATT and asked them to change it to LTE.
Now I can change the settings as needed.
So if ATT sets to 4G, you wont be able to switch to LTE.
Is this the only way to change the preferred network mode on SAMSUNG-SM-G900A, ie. by going to details mentioned under #2
Has anyone tried this lately? I know the old 4636 code worked on older galaxies buy I can't get my G900a to respond. Still on 4.4.2
Work fine here on 4.4.2 and 5.0

Hey, im not sure what i should have called this thread but anyway, when i lose LTE on my phone it used to switch to H+, now it switches to 3G. Basically im wondering what i need to switch in the default file to display H+ instead of 3G
i hope this makes some sense
Well 3g and H+ are different. You can check to make sure in data settings that you have GSM/WCDMA/LTE AUTO set in there.

I basically loose the H (HSPA) service with my operator by taking the 4G package, I get 4G LTE, and in bad coverage area's, which is almost everywhere for Vodafone UK except major cities, I get a G or an E unless I can connect to a wifi.
