I found sthg really weird in my unlocked ATT tilt today. I m curently using T-mobile. As many of you know that, you rarely get signal/reception in basement if you are using t-mobile. but today, when i went down to the basement, reception was gone w/ the E icon, then after a while, the E icon was changed to G, then the signal was detected and I could make phone call too. and the carrier on the screen is still T-mobile. Nothing changed except the E/G Icon. I then checked w/ my friend who is also using T-mobile(nokia phone), no reception at all. Does any one know what the difference between E and G icon on top of the screen is? will I be charged for some type of service fee or something if I make calls or use the Tmobile web w/ the [G] icon? please tell me if you guys know anything about it.
thanks in advance...
The "E" is picking up an edge reception, i get it in the UK sometimes because i have a crappy t-mobile signal in my house. When its displayed i cant make phonecalls/txts etc so might be picking up another carriers signal because i dont think t-mob uses edge here. The "G" is gprs just the basic slow phones signal.
G is when GPRS is available, E is when EDGE is available. No extra charge. This could have been easily answered by looking in the manual.......page 29
I guess this may be different for T-Mobile (and could possibly vary on the ROM you're using) but the E on my device is for EDGE service, and G is for 3G service. 3G, obviously, is the better of the two. But I'm on AT&T of course...

I don't think T-mobile has 3G here in NY.
Thanks for all the replies above
so, the signal of GPRS is stronger than the EDGE? if yes, then we are all able to get reception even if in basement. No need to get verizon anymore... lol
but why can't my friends' phones picked up any GPRS signal? is that because their phones don't support GPRS?

And then H (HSDPA) just defeats them all.
One Icon to rule them all, One Icon to find them...

No no no, g is not 3g, G is GPRS, the slower version of EDGE, thats the reason why you can call in your basement now!
G is GPRS
E is EDGE
3G is UMTS
H is HPSDA
first is the slowest, last is the fastest, so if the fastest is not availible, it switches to a slower one, like happened in the TS situation
My icon used to pretty much always be on 3G, sometimes switching to E when I drove to my brothers house which is about 25 miles away. But recently I haven't been seeing 3G at all, but only H. I did see E a couple days ago, but I haven't seen 3G in more than a week now. I thought H was only supposed to show up when you were using a data network or something? At least that's what I read somewhere on here a while ago... Any explanations?
that H is wat you want to see
first H shows up when downloading data means you're using HSDPA, but is H shows up when u're not downloading data, you have HSUPA too
Ya, as XtreMe_G indicated this is easily answered by opening up the manual.

Yeah, I know HSDPA is what I want to see the most, but when the hell did AT&T have HSUPA? I live in the Washington DC/Northern Virginia Metro area... Anyone else from the area noticing this?
And as for the OP's question about E and G, there is no difference between signal strength and ability to make voice calls. E just means that the cell offers Enhanced G.
Whether you see a G or and E (or 3g or H) is dictated by the data connection offered by the cell - which has no baring on voice at all.
If you have any signal, you should be able to make voice calls - the speed of the data connection (ie for web/email etc) is the only thing indicated by the Letter - except that 3g/H can also do simultaneous voice and data where G (and E) can't.

That's what I thought, but then I tested my data connection speeds and when I'm supposedly on basic GPRS the speeds are much greater than anything either GPRS or EDGE could accomplish (unless EDGE was having a perfect day).
I did notice however that it only shows G instead of 3G when I force the phone NOT to use 3G while 3G is available in the area. If I allow it to use 3G service it shows up as "3G" and the speeds remain the same. As soon as I force it not to use "3G" it shows up as just "G" but the speeds stay the same.
"E" or EDGE always seems to be indicative of the correct speed. But for my device it switching between G & 3G are one in the same, and the speed doesn't change at all.
Could just be a glitch with the software on my phone, but that's how it is for me.

Thanks for that.
That will be the reason that when I used a tomtom one and got traffic via my bluetooth phone, a traffic update would kill any call I was making.
I assume I am correct in also expecting my TyTn II to ignore voice calls (or drop gprs data connection) if I am using the TyTn II for internet access for my laptop and a voice call comes in?
I sometimes get the E but as far as i know we dont have Edge in t mobile UK.
how do you remove the G?

Same thing here in Baltimore. I have not seen my 3G icon in a while, only the H.
data speeds seem to be the same though.
My G Icon changes to E Icon
Hello,
I have a small problem...
First I will Switch ON my wizard. After Switch ON I will see a G Icon at top of the today screen ( That is correct ). When I press the power button, the screen goes off (i.e Goes to Sleep Mode ) and again I press it to wake up. but now the G icon will change to E icon.
I not understanding why this happens.........
Also when i connect to GPRS internet but it shows as I am connected to EDGE with E icon ( This happens on when I wakeup the device )
My probem is that why the icon should change when I wakeup the device.
To confirm you that, I have also disabled the "EnableDifferGprsEdgeIcon" setting in registry.
This problem will not occur in wm5 but only in wm6 or wm6.1.
In wm5 There is no E icon or it is not showing as "connected to EDGE" when I connect to GPRS internet.
Please any one help...............
Thanks in advance

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.
Where Im located I dont get to use 3G very often so Im not very use to it...lol...so the other day when I went to my gym in another town in 3G coverage I was on the internet just a little and noticed it was faster...but it still had the E beside the antenna...so I was wondering if the phone is going to do anything different to indicate its using 3G other than just being faster?
Thanks! By the way Ive got a X2...
No if you are seeing E, that means you are getting EDGE reception, which is faster than G (GPRS) but still sigmificantly slower than if you see an H or 3G icon.
In summary, the speed classes are as follows:
G < E < 3G < H
A quick search on Wikipedia should clear up any more questions you may have.
Oh ok...thanks! What does H represent?

H or HSDPA, here you go
http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access
My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?
From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!
I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...
Hi, it's your phone doing what it should by seeking the best signal.
H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..
Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g 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.
