AT&T HSPA (H) and UMTS (3G) coverage. - XPERIA X10 Q&A, Help & Troubleshooting

Hi All,
Ever since I debranded my phone when I first got it, I almost constantly get "H" rather than "3G" in my home. However, lately I have been getting a mixture of H and 3G. Is AT&T "downgrading" their network or something?! Knowing that they are crappy, I would not be surprised if they are actually starting to "cap" or "throttle" the speed of their network in some areas.
Anyone else experience a similar thing?

No they didn't. H comes in when you do something like go on the browser. Otherwise it just says 3g but its really h

That's the thing, even when I go on the browser it sometimes stays on 3G.

Afaik they are not throttling their service on the 3g end only when they light up the lte. Mine has been consistently h unless it's idle as someone suggested.

Sometimes. Not since switching from Rendeiros last rom to his latest. I would reboot then try it again with wat u were doing. That worked for me

Yep same here. 3g as I type this, obviously not idle... Been seeing it more lately but not all the time

3G signal on x10i

Right I got me a bit of an issue.
Dunno if it's been covered by someone already, but there's only so much the search bar can do from my phone.
I am using X10i I am on O2-uk
Even when I am sat next to someone that has full 3G signal, I am totally unable to get anything.
I've had this phone for just a year now an idea have never had a 3G signal. The best I can do is get H
The status bar claims to have 3G bit as soon as I try an use the connection, for ANY reason, it instantly switches back over to H
So basically my issue is........ WTF!?!?
Why not ant I connect to through 3G? And does anyone else have this problem? Is there fix for it? An app or something I'm missing?

The infamous "H" ...
From what I understand H is better than 3G...in fact its 3.5G! Increased download speeds when compared to regular 3G..
"H"is a good thing..
Sent from my X10 using XDA App
Really? If that's the case then I should have seen 3G at some point in the last year when I had worse signal???
Sent from my X10i using XDA App
Nope. Afaik 3g depends on availability in your area. Not related to signal strength.
Sent from my X10 using XDA App
Yeah mate the h is for hsdpa which is, as said above, better than 3g.
Edit: if phone can't get hsdpa it will go for 3g. If it can't get 3g it will search for edge (will just have an e). If it can't get e then u need to stop living on mars as u ain't got no mobile internet.
Sent from my X10i using XDA App
You can't really complain some people have issues even getting 2g while your having 3.5g
Sent from my X10i using xda premium
Ok
Thanks guys. I was under the impression 3G was better than H
Cheers for clearing that up

Question for AT&T users.

I had a question for you guys using the international on AT&T.
On my GS2 I remember when data was not being used and was idle the signal meter would show 3G and switch to UMTS and when I used the connection it would switch to H/H+ HSPA.
With my GS3 however, it's constantly showing H even when it's idle. It's NEVER really goes into UMTS mode even when it's idle. I've seen it switch to 3G for a split second every now and then, but then switches right back to H in a split second. In my status I see it's using the HSPA network, not UMTS. The times that I saw it switch to 3g for a split second (I happened to have the status open) I saw it switch to UMTS then switch right back to HSPA.
I know switching to UMTS when the connection is idle saves battery life So I'm wondering since mine doesnt switch to UMTS if it's affecting the battery life
I've tried different modems, in network settings it's set to Auto.
So my question (after that wall of text) is does your phone switch the UMTS when it's idle and show 3G? Or is it constantly showing H like mine?
I'm trying to figure out why the hell it wont stay in UMTS when there is no data activity. If it does switch to 3G/UMTS when it's idle anyone have any ideas what could be going on with mine?
anyone? lol

I actually asked this question myself a few weeks back and never got a straight answer. It would be nice to know, since mine is always on H. My S2 did the same thing, would always switch to 3g when idle.

Maybe you guys should try gokhanmorals fast dormancy app from the play store.
And maybe take a look at the thread that was floating around here about proper fast dormancy settings for at&t.
Mine switches from h to 3g as soon as it stops transferring data.

Mine switches to 3G as soon as data is stopped transferring. No problems here. and it will sit on 3G until data kicks in again and picks up to H+

hmm so it also happens to K Rich's phone. Can you do me a favor? from the dialer hit *#0011# what band does it say when it's connected to 3G/UMTS?
I can also get it to stay on 3G constantly by changing a setting in the advanced phone control menu, but then it doesnt switch to HSPA when data is active.
Sorry never mind. It doesnt do it anymore since i am on LG8 :/

havent personally seen any data drops (either in lte areas or 3g only)
if its something that persists and is unusual for your area id try for an exchange w/ vzw

Are you in bad signal area? Sometimes it gets confused tries to go between 4g and 3g.

I am in 3g at the moment. But several towns around me within a 8 to 10 mile radius has 4g. We should have 4g soon. I also have noticed when I wake my phone up sometimes my 3g is gone and then comes back.

I am on tmobile and it works pretty good I get 4g in some areas, it just depends on how strong the 1900 mgz signal is in your area.

Like the previous guy said you get edge speeds unless tmobile has refarmed the 1900 MHZ in your area for HSPA speeds.
Below is the list of cities where tmobile has refarmed the 1900 MHZ.

The modem is the same chip as the nexus 4 and note2, so I would bet if you use their radios and ril, you would have hspa and hspa+.

Hey guys! Just got my phone yesterday and got it unlocked. For some reason though I'm not getting Data at all. I should be getting something since I live in Boca Raton, FL and that's not too far from Ft. Lauderdale, one of the cities listed on the link Kirdroid provided. On my previous phone (HD2) I got HSPA speeds in my area. You guys have any idea of what could it be? Or any other tips on what network settings i should have?

Yes that is exactly what I was missing. Thank you very much! Unfortunately I'm getting edge here where I work, but the connection here was irregular as well on my HD2, so I hope it's just the area. When I get home later I'll give an update.
Thanks again!

Wow the third option made my speeds faster! Thanks I was having issues with connectivity but that seemed to fix it up!
Update:
The first settings worked best for me. Although the HSPA+ speeds are somewhat irregular on the area where I live, it works great on the neighboring area.
Thanks for the help samomamo !

No need, all I did was unlock and input the settings for the APN. It's been working great!
Does your phone stay connected at all times? Mine disconnects from the network rather frequently for no reason and the data connection is spotty on certain apps.

My connection is spotty too, but that really depends on the area. On areas closer to the Antenna it stays connected most of the time. But where I live my experience is close to yours.
I am on T-Mobile, did the Nexus conversion, and I can confirm that I am unable to get 3G on the 1700mHz band. I live next to a T-Mobile tower, and my last phone (TMOUS HTC One S) got 3G signal without a problem, so I know it isn't the area. I am only able to get EDGE and I have the Nexus 4 modem M9615A-CEFWMAZM_2.0.1700.33.
Sshshshsh! This illegal! No unlocking!!

To you guys who live in Florida:
I spent my day today in Miami Beach and the hspa+ speeds there are constant and stellar there. 4-5 mbps download and 2-3mbps upload. That kind of proves my assumption that it's a matter of the area and not the phone itself.

Miami is probably already refarmed with the 1900mHz band. Where I live about 40 minutes from Tampa, I do not get 3G from my home, which is near a T-Mobile tower.

Go with 3rd vpn Im getting 8-10 mbp so fast lovr it

3g connection?

I am not sure I have an issue or not in all honesty. I have flashed to the new baseband on my lg optimus t. I am using hephappys ics 9.1.4 but I never get a 3g icon. My connect speeds on mobile network show a h symbol and are about 2Meg down by 126 k upload. I am not really sure what I should see for a 3g connection.
Sent from my LG-P500 using xda app-developers app
Google and read more about 3G and H.
H stands for HSDPA.. means 3.5G basically faster than 3G.
Good to know. My stock rom must have just shown 3g instead.
I am surprised that updating the baseband has improved the signal as much as it did. I went from 2bars to 4 bars.
It's also nice to not have to flash a rom then flash the baseband fix.
