is there any way to make the phone roam onto a 3g network over the others...i am in sweden where there is a good 3g network, but i am alsways on H & G, hardly 3G.
Thanks

You should not complain then, since H means HSPDA, which means 3G+ and is faster than 3G.
Regarding G, it is supposed to mean GPRS, which is indeed the slowest one.
Maybe your carrier didn't not bother to maintain the intermediate services such as (E edge, and 3G umts).
You get either the fastest or the slowest.
G means GSM
And yes, HSPDA is better than 3G
i know its HSPDA, and G means gsm or gprs, but with HSPDA meaning hi speed, i cant get video calls or streaming when its on H.....if you get me, but i can use them when i get a 3G connection
just tried again and now it works, strange....

I did the kaisertweak to enable the H network or whatever (yes i don't understand it)
the network still says E or 3G . It said that all the time, for the last few days.
Then I was messing around trying to get this gps to work in google maps and I noticed it switched to H. but now it's back to 3G. is this all normal?
Ive noticed that too..
no idea what it means
what operator are you with in what country
check with them to see if you have hsdpa reception my hsdpa is enabled but since i dont have coverage i stay at 3g
hsdpa is a better version of 3g
its often called 3.5g 3g+ or mobile broadband so basically all the twaek is is to let your phone get the faster connection but only if your operator has the signal to do so
The H icon (HSDPA) is a step up from 3G it allows anything up to 7.2Mbs transfer but the HTC instead of contantly allowing this to be active thus creating massive battery drain only allows it when a data connection is active and data is being transferred any other time and you will only get G, E or 3G
3g alows ypou to have video conferences but H mean HSPD fast internet 3,6Mbit or 7.2Mbit depands that the difference i belive.
exactly just because you enable it doesnt mean you can recive it
I turned hsdpa with kaiser tweak also. I noticed it will only connect to hsdpa when transferring data (IE, emails, weather, ect.). Otherwise it will go back to 3G when on the today screen, or offline tasks. I guess its to conserve power?
Maybe thats what your seeing?
ok thanks, looks to be normal =]
I can't seem to figure out why sometimes I get a G connection vs a 3G connection based on the radio icon in the notification bar. Does anyone know what the difference is? G seems to be much slower then 3G.
G stands for GPRS which is a 2G connection and doesn't use the 1700MHz spectrum like 3G (HSPA) does. There are several reasons why your phone would switch between GPRS and 3G. Signal strength and 3G coverage area is limited in the US for TMO is the most common. Certain types of electronic equipment can interfere with 3G as well.
Thanks for the info, I wasn't aware of GPRS. Typically I get E (EDGE) or 3G but inside my office I get GPRS, chances are it's the equiptment. Explains why my connection is so slow inside.
After digging through pages of posts about data speed issues and 2G vs. 3G vs. 4G/LTE, can someone with good expertise and knowledge summarize exactly what the phone supports and how it does it? I am seeing conflicting comments, so it is a little confusing. Also, please clarify a comment I recall seeing from at AT&T person that that the Vivid has one radio that switches between LTE and HSPA+ rather than having as separate 3G radio as earlier LTE phones did.
Or point to a good tutorial.
Thanks
I'll see if I can help!
So in order from slowest to fastest, the GSM data technologies are:
2G:
-GSM
-EDGE
3G:
-UMTS
-HSPA
-HSPA+
4G:
-LTE
Most Android phones display these as G, E, 3G, H, & H+ (don't know what stock Android displays for LTE). The Vivid, however, displays G & E, then displays 4G for 3G, H & H+, then 4GLTE for LTE. So no matter what 3G network your on, it'll show 4G (because AT&T thinks H+ counts as 4G), then when you're on an actual 4G network, it'll show 4GLTE.
As for the single radio, yes, that's true. LTE is a GSM based technology, so a single radio can handle all of the above connections. This is different from Verizon, which uses CDMA for its 2G & 3G networks, then switched to LTE for its 4G network, necessitating two different radios: one for CDMA, one for LTE. AT&T, however, has been GSM from 2G on, so one radio can handle everything. This will most likely continue to be the way it works: Verizon (and eventually Sprint) phones will require two radios for two technologies, AT&T/T-Mo phones will only require one.
This leads to one consequence, however, concerning simultaneous data & voice. No LTE network currently implements voice communications, they're purely data. Even when they do implement it, it'll be VoIP based, so it'll just be more data (This will be called VoLTE for Voice over LTE). Therefore, since this isn't implemented yet, phones must revert to the 3G network to make voice calls. On Verizon, since they're two different radios, you can continue to use LTE data while using CDMA for voice. On AT&T, they're the same radio, so dropping down to 3G drops the LTE connection. You can still use simultaneous voice & data (as you can on just about any GSM based network), but you just don't get LTE speeds.
Make sense? Let me know if that helps!
Thanks, BJG222
That's what I wanted to know. I appreciate the info.

Wow thanks, a very helpful summary of so much **** otherwise kinda complicated to figure out.. quick question, under the Network menu, my phone always says HSDPA, not any of the other options you listed above. This means..?
Here is an interesting read...Explains alot, considering I bought my White Vivid in Houston and got amazing speeds on LTE, and can barely stay locked on an LTE signal at home here in the SW burbs of Chicago.

Actually, HSPA+ is also categorized as 4G.

Well, AT&T & T-Mobile claim this, but it's not really true. UMTS = 3G; HSPA was an upgrade to that, call it 3.5G; HSPA+ is an upgrade to HSPA that incorporates higher bandwidth behind the scenes, more of a 3.9G. LTE's actually a new protocol. Technically, by the initial ITU standards, that's not even 4G (LTE-Advanced, the next upgrade to that, is the only one that does), but they've since expanded the definition to include LTE, too.
so we don't get a different symbol for 3G...so how do we know when we are using 3G verses HSPA and HSPA+ ? (other than speed)...
sucks...
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.
Hi guys!
I just got my contract with mobile internet in it.
Each month, I get 1GB of data and it's awesome!
But I have some questions/problems with it.
When I connect to the 3G network, I sometimes have an E-connection.
It's pretty slow, but I found out this is some kind of 2G netwerk (called Edge).
Mostly I get an H-connection (HSPA(+)) I think and that speed is fine.
But sometimes it changes from a fraction of a second to a 3G-connection.
I think that is what I really need, but how can I "force" it to always go to 3G?
My carrier supports Dual carrier 3G, so that "should" double my 3G speed.
It would be awesome if you could help/inform me!

H (HSDPA or HSPA) is faster than 3G is faster than 2G.
I also get switching from 3G to H a lot at home were signal is not good.
