hi!
i am using a tmous hd2 with the stock 2.13 rom and the recently released 2.15 radio. up till now i havent really bothered using packet data on my phone because i am a wifi guy... only recently did i start using packet data frequently...
i noticed two things out of place:
1) for some reason i have never seen hspa service on my phone. my operator runs a 3.6mbps dl 2mbps ul hspa services. whenever i switch to 3g and connect data, i always get a 3G written over the signal bars. and i have never seen speeds over 42kB/s (~384kbps) in several months of use. i have full signal strength in both 3g and 2g. if i am running 2g, then i get an E as expected over the signal bars. i have put in all the access point settings as defined by my operator (which are common for both 2g and 3g). i have enabled hsdpa/hsupa from winmo settings->connections->advanced n/w. is something amiss with the hspa settings on the phone? i really want to confirm that i have my phone set up right before i muster the courage to call up customer care.
(for someone from bombay, india, i am running mtnl 3g prepaid with following settings:- ap:gprsppsmum u:mtnl pass:mtnl123. this in itself is quite baffling because mtnl delhi has separate aps for 2g and 3g whereas the bombay network has the same ap for both. ap=access point)
2) i have never seen the H/3G/E/G icons on my taskbar. i mean the ones that are NEXT TO the signal strength icons. the space between the headset and the signal strength is always empty. isnt that particular icon supposed to show 'availibility' of the respective type of data connection? i read somewhere a long time ago that the icons are ROM dependent. but i am pretty sure i have seen snapshots of tmous phones with those icons...
i have been using bsnl cellone 3g since feb and i always got H in south india, even while roaming,...in few cities up north, like lucknow, i got only 3g icon displayed..i guess it should be H in mumbai..
from what you say, i think you have not enabled HSDPA/HSPA setting in the phone...do that..it is in settings/menu/all settings/connection manager or ?phone / advanced network ( i think...can't tell exactly where...iam presently on the android side...)

no, i have enabled hspa (both directions) from advanced network. i said that in my original post as well. what windows rom were you running? also did you just get H speeds or see the H icon as well?
both H icon and speeds on 1.48 wwe and 3.14 wwe roms
Hi I use an unlocked TMOUS HD2 here in Italy with the italian carrier PosteMobile and experience the same problem of silenced3 (almost the same as I still haven't tried a cellular data connection): My phone doesn't show the kind of cellular signal available, only when it data connection is activated it says what type of connection it's using. Anyone knows how to solve this?
Thank you for your help...

Hey guys, i was wondering if someone knows something about this and what would be wrong with it.
I'm not receiving any 2g or 3g, only G or H. Though H very very few times. While friends of me receive 3g while im at the same place as them.
I have a T-mobile g2 touch, rooted to modaco with the newest radio rom. I had the same problems with standard rom and 2.73 t-mobile UK roms.
I live in holland which has decent 3g network i guess....
I just wanted to know if someone encountered the same problems or have any intel on this, before i unroot and go to t-mobile store.
thnx in advance!
edit: oh and yes, i have web n walk obviously if you wonder
wups, posted in wrong forum! my bad!
I also get more HSDPA and GPRS/GSM than 3G.
Only few times I had 3G in some Citiys.
Never saw Edge... (a friend has a lot of it)
Switzerland, Orange
Never actually saw my 3g pop up, i spend alot of my time in the major cities actually too. =((
You won't "see" 2G, because G means GPRS which is 2G. If your networks provided 2.5G, you may see EDGE, "E", but most European networks never bothered to implement it because they'd already gone 3G and there saw no need for EDGE. As far as I'm aware, O2 in the UK hastily added EDGE to their network purely to support the original iPhone.
Obviously, when it comes to the icons, "H" (HSDPA) is superior to "3G" (standard UMTS) so I'd only really be concerned if you're getting "G" when everyone around you on the same network is getting "3G" or better.
Regards,
Dave
Which is my case, but what could cause this? t-mobile forgot to turn it on on my subscription or something? lol
So Im sure any of you on Tmo UK will be aware of this new option they've given us whereby you can opt-in to use the orange networks if you lose reception from Tmobile........
I thought to myself "yeah...... why not..... cant hurt"
Seeing as I barely get a 3G / HSDPA signal where I live I thought that perhaps it might kick into "orange mode" and give me some 3G action.... (sadly it doesnt)...
Anyway since I opted in Ive noticed that sometimes when Im on the Tmo/Orange signal, the "Edge" (E) symbol is displayed in my taskbar......
Its definitely a lot faster than GPRS but doesnt seem to be as quick as HSDPA, I thought that perhaps it was there in place of the 3G symbol but sometimes that will appear too.....
I thought "Edge" was only available in the US.....
Does Orange have some kind of in between speed that I was previously unaware of??

I don't know it fore sure, but France Telecom (Group holder of Orange) have invest a lot in UMTS maybe it's that you got.

in order of speed, edge has been used in the uk for years
So you texted Yes to 2121 as well.. I honestly cannot spot any difference, still haven't gotten Orange coverage yet

lol you probably wont need it in London........
coverage is poor out here in the sticks though..........
it perhaps won't auto switch networks, because it knows t mo is the preferred network, unless there is no t mo reception at all.
you maybe need to add the orange network as a preferred network
settings menu all settings personal phone network tab set networks let's you set the preferred order and such, so if you find yourself in an orange dominant area move orange above tmo in the list.

OK I'm generally a proud Londoner (Not a bad thing lol).. But sometimes I've been in the middle of Oxford Street and notice I have no reception, London isn't a great place for good reception is some areas, you get better reception in residential areas then main high streets
@sam...
Mine seems to switch even when I have a reasonable amount of signal.
9 times out of 10 today when I looked at my phone I had the roaming and edge symbols sitting in my taskbar....
I generally never struggle for basic network coverage so I was surprised at how often I'm on orange signal...
@don..
Yeah I guess there are plenty of things that could hamper you're signal...
Maybe it's that famous london smog I've heard so much about

Battery Drain
I've also just signed up to this as I get poor signal thru T-Mobile when in some buildings whilst at work.
Problem is that I've noticed a significant drain in battery since subscribing presumably as the phone is always comparing signal strength of both Tmo and Orange and switching between the two periodically.
Is there a way to change carrier manually through some form of *#*# dial code rather than to switch to manual and select the desired network as this takes a while? I don't seem to have the option to set my preferred networks as a previous poster mentioned.
I've had mixed experience with this - make sure your sense and activesync settings are set to NOT download data when roaming - the Orange/T-mobile thing calls itself roaming and I kept getting password incorrect responses from gmail on activesync, I assume because it was trying to access the servers from different IP addresses rapidly. You do not get 3G etc from Orange - your data comes over t-mobile, you just roaming onto the Orange network when there is no signal on t-mobile, so it should give you better call coverage, but for data switch off roaming so it only tries to access data when on t-mobile.

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!
Sent from my Vibrant using XDA App
Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
Hi, I looked for this in all motorola forums but I couldn't find any real solution.
It seems the latest update to my home network (HSDPA to HSPA) is not well received by my phone. My battery is draining really fast since this upgrade.
Is there a way to enable ONLY HSDPA? I mean, HSPA is great for downloading and uploading, but battery life is really poor. I had very good battery life with HSDPA and I'd like to set my phone to this type of data connection.
Somebody told me to look for some entries in build.prop but I didn't find anything. Does someone know how to do it? Thanks

Hey, thanks for your help. Well, I'm not suffering battery draining for any other reason. I don't want to use 2G networks only. Just want to change HSPA to HSDPA. That way, I'll go back to having the usual battery consumption.
Any other suggestion?
HSPA is a term that encompasses High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) - if your network was using HSDPA, it was an HSPA network.
Enhanced HSPA (HSPA+) is an enhancement to HSPA that enables download speeds of up to 21Mbps and beyond, up from the typical 7.2Mbps. The Atrix is a 14.4Mbps compatible HSPA+ device.
So you saying you don't want HSPA, but want HSDPA doesn't make any sense. Do you want to disable the increased upload speeds? (HSUPA) or the HSPA+ speed enhancements? (up to 14.4Mbps) I know Samsung have an option to disable certain parts of the network through a hidden network, no idea about the Atrix though.

Yes, I want to disable HSUPA (what makes it HSPA) since it's killing my battery. I found a lot of info on Samsung phones but I don't know how to do it in a Motorola mobile
Sorry to bother again. Any solution yet to prevent phone from going on HSPA and stay in HSDPA? Thanks in advance
Just for your information, I found some build.prop tweaks to set HSDPA only, but none of them worked. Any ideas? Am I doing something wrong?
Thanks

BUMP... Still trying to set phone to HSDPA only... Any thoughts?
it can be done, it took me three weeks to figure this out. we had a flood come through here about three weeks ago and it did something to just one antenna on the tower, i dont know what it did but it prevented anybody using a phone on hsupa from using their internet on their phone, i called att multiple times on the issue with no fixing of the tower that was transmitting a bad hsupa signal, the same antenna was transmitting a good "3g" signal or "hsdpa" both of my 4g phones would work anywhere else in the world except for at my house where the bad hsupa signal was. so i knew i had to find a way to downgrade to hsdpa to get my phones operational again, no help from att as to when or even if they would fix the towers. att thought i was crazy because i was the only one complaining about it because everyone on 3g was unaffected, probably only a handful of houses on this one antenna, att locks you out of your phone from being able to go to 3g or 2g, all automatic. 3 weeks of this crap then one day i remembered when the atrix first came out hsupa was locked out, remember all the scoff att got for that one, so here's what i did to shut off hsupa and get my phone back running again:
1. make sure your bootloader is unlocked - not sure if this will brick your phone if it isn't
2. download these radio packages http://www.megaupload.com/?d=V0LDOGFJ
3. flash the one radio that says att shipping radio or something like that through rsd lite (this is the original radio that shipped with the atrix) and don't worry its safe to flash if you are on gingerbread..
4. reboot your phone and you will be locked into 3g or hsdpa thus locking out hsupa
5. if you want to turn hsupa back on just flash the other file
this method worked great for me and got my phone working great again and no hsupa for me anymore until att gets the tower fixed which may be never since i'm probably the only one on this particular antenna with a hsupa phone.
all we need now is a nifty dev that can hack one of these radios to shut off automatic network selection for those of us that are stuck on it.

Hey pal, your method worked! After flashing the old radio, the phone is on HSDPA only and battery life is way better, back to Froyo times. I don't really care about the enhanced upload. Download speeds are as good as they were on HSPA.
Thanks a lot.
Can you please upload those radio again? I'm suffering the same thing with my atrix. Thank you.
Poco F1 (MIUI Global Stable V11.0.8.0.QEJMIXM ROM) has significantly better 4G signal strength than 3G or 2G. In fact I got problem with that, when I'll recieve call or make a call, the phone automatically from 4G goes to 3G or 2G, and in that moment signal strength bars goes from 5 bars (4G) to 1-2 bars (3G) and often other side cannot hear my voice. Later I choose manualy network (3G or 2G) and when I try yo make a call => "Cellular network not available"
What should be the problem? Is it software or hardware problem? ...btw I make a clean install/flash thru fastbot of MIUI Stable V11.0.8.0.QEJMIXM few days ago, but I cannot notice some differences

It means that VoLTE (Voice over LTE) is not enabled or it is not available in your region. That is why it is switching to 3g network to make a call. As for the signal bars, never trust miui on that. Got to about phone -> and find a option where it shows imei, sim status, etc.

Yes, in my country VoLTE is not available, but I don't see that as an insufficiency, I use it only for data/internet 4G.
MIUI signal bars should "work" same for both 4G and 3G/2G, i think it is some other problem. Btw use it code *#*#4636#*#* (testing mode) and there i can manually set my network (WCDMA only, GSM only, LTE only, CDMA, TD-SCDMA/UMTS... and all variations of them). Usually LTE strength signal is "70-80dbm / 50-60asu". When I set to WCDMA only or GSM only it is ""100-110dbm / 1-10asu" and that's in the middle of the city (where I live). When I enter some Mall, stairs of building or hike on local mountains, when I want to make a call, the result is "CELLULAR NETWORK NOT AVAILABLE " :crying:
Does it can be antenna problem? But then, why 4G signal is far better than 3G? Does it have separate antennas??? I got no idea really what should be the problem about that

Without VoLTE you cannot make a call on 4G network. The SIM will automatically switch to 3G/2G. It's the same across all phones, all carriers, and in any country.

It is OK that. I know that. In fact, I GOT PROBLEM WITH 3G AND 2G SIGNAL STRENGTH. I mention 4G just to compare signals. I got 5 bars on 4G and 1-2 bars on 3G/2G on the same location. I have super fast internet thru 4G (50-100mbps), while when I set manually to 3G it didn't even connect data, furthermore, I cannot make a call (Cellular network not available). Obviously it is a strange problem. I'm not arguing about VoLTE or 4G...
Is it the same antenna for 2G, 3G and 4G signal? Should I replace it? I will repeat myself again, I can't get HOW CAN 4G signal be better than 3G/2G?!
I insert both SIM cards (with POCO F1 I use dual sim cards) to other phones (Xiaomi Mi4c, Alcatel Pixi 4, Lenovo A536...) and everything is OK with all of them. So, that means it is a POCO F1 problem.

Try changing slots. Or try a different carrier. The culprit could be your network provider. If the problem still persists go to any service center and get it checked. BTW it is actually strange to see that 3g/2g network is weaker than 4g. Usually it is the other way around.
