Hi all.
I'm under the impression that umts = 3.6mb and hsdpa = 7.2mb and hsdpa+ = tmobiles sexy new 21mb service.
Am I right? I'm asking because my phone switches to hsdpa from umts only when I'm using data. Its always hovering on umts when I am on 3g.
Thanks!
With cm rom I also saw the fluctuation. 3g was umts and the h was hsdpa right?

I bought my HTC Diamond on UK. I updated the ROM to the RUU_Diamond_HTC_HK_WWE_1.93.831.1 this was supposed to make my phone QuadBand. It does work in USA (Boston) where I live. But I have never seen my phone doing 3G and speed test top was around the 1xx kbps.
Any Ideas?
PS. I am on the ATT network
Are you sure you have 3G coverage in Boston? Do you have a USIM-card (which I was told to be required for UMTS stuff)?
3G speed
I did look at the ATT coverage map and it said that I do have coverage.
How do I know what type of SIM I have? The SIM does have the 3G logo on it.
Are you sure your phone has the bands?
Check the Band setting, Settings->Phone->Band,
in the dropdown box for "Select your GSM/UMTS band", my US 3G ATT phone shows the following options:
Auto
UMTS(850+1900)+GSM(850+1900)
(oddly enough, the settings have to be on Auto for the phone to work..)
When I bought my diamond, I was curious about my sim too, so I took it into the ATT store and asked if it was the "latest 3G sim" and he said yes. Mine is half white (top) & half Blue (bottom), with a orange 3G fireball in the topright corner.
If yours matches all that, then take it to the ATT store and see if you get 3G in the store
Also..if you have doubts, I've had multiple Sales reps in the store tell me I can get a new Sim for free at any time, just need to ask.
3G
I do have that SIM half blue half white with the 3G fireball logo.
On my select network I have
Auto
GSM
WCDMA
on the GSM/UMTS band I have
Auto
UMTS(900+2100)+GSM(900+1800)
UMTS(850+1900)+GSM(850+1900)
UMTS(800+2100)
UMTS(850+2100)+GSM(900+1800)
UMTS(850)+GSM(900+1800)
UMTS(1700)

What ROM do you have?
RUU_Diamond_HTC_Europe_1.93.401.2
RUU_Diamond_HTC_Europe_1.93.401.2
Does this ROM supports USA 3G????
Sorry for my English
You have the European version and have only HSDPA 2100 / 900 (3G) and probably ATT works in HSDPA 850 / 1900, if this is the problem, sorry 3G is impossible for you, because is a hard problem, not a soft problem, search in this web there are many post about this. The European is quad band in GSM but not in HSDPA (3G)
CArlos
How about if I use another ROM
If I use another ROM ? would I be able to do 3G?
No I think it's impossible since it's different hardware I believe.
I think the one you have from UK, it only contained HSPA 2100 and US /Canada is using HSPA 850/1900, that's why you don't have the 3G signal.
Quad band only for voice and EDGE.

i think i have an Eropean model from UK Vodafon which has the front camera... but i am not sure about 3G !
????
I hope someone can help me or at least point me in the right direction.
Im in the Philippines and my g1 is unlocked/rooted with the latest cyanogen rom 4.2.6.
The network im connecting to is smart communications with according to http://en.wikipedia.org/wiki/Mobile_network_code has:
515 03 Smart Gold Smart Communications Inc Operational GSM 900 / 1800; UMTS 850 / 2100
our phones have Modes GSM 850 / GSM 900 / GSM 1800 / GSM 1900
WCDMA 1700 / WCDMA 2100
So i should be getting a 3g signal or something but im not, my phone is not even making an attempt to connect to 3g. I have checked the settings and i cant find where to enable 3g. Use only 2g network is not checked. my apn settings seems to be correct but its not even getting to the point where it tries to connect to 3g. I have no 3g symble or edge symbol. please help..
help someone pls
I am seeing GSM/WCDMA in the network mode on my Galaxy S. Is this different from UMTS? I think GSM-UMTS is the right wording? I am in India.
in simple human non tech terms
WCDMA = UMTS = 3G = Data
GSM = voice
ok... my telcom operator website says hspa is faster than wcdma ...so wanted to cross check... thanks

Isn't it
WCDMA = UMTS = 3G Cell (voice + texts)
GSM = 2G Cell
HSPA = Data
I've had my phone connected as UMTS where I had no data but was sending and receiving texts. Although the most interesting of all is when instead of an H I had a G when Bell doesn't have a GSM network...
yes & no
you are right in some stuff, and that's how people gets confused by all the different techno terms
HSPA = 3.5G and it needs WCDMA for it to work
Text as in SMS doesn't need 3G, any GSM can do Text, but again that's complicating things
2G is better known as EDGE on marketing and Sales people talk, it's so uncommon to hear or see an advertisement say "blah blah blah and we offer 2G Data!" 0_o
there are more.... but anyways lets keep things simple
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.

Hi,
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with 3g. I have looked for APN information and the info downloaded to the phone when I connected to network is identical to what is listed on the net.
tmobile docs url not allowed
i had to add the MMSC setting since it was not there as listed in step 12.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And
wikipedia entry for tmobile not allowed
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.
John
