I'm getting weak signal but I'm not sure which band is the problem (we have LTE1800 WCDMA850/900/2100 in the same network).
Where do I find out which of the 3G bands is my phone registered on?
Thanks

Can somebody please explain GSM vs WCDMA vs UMTS for the bands?
My impression is GSM is 2G and UMTS is 3G and both can supply regular phone service? What's WCDMA then?
T-mobile USA is GSM 850/1900 and what else?
I was thinking if I specify what network and band to use it'll use less batter (ie. no 3g unless I really need it).
this is a really easy google search... or just go to wikipedia....really any search you would try will answer your question.
(you're half right, but mostly wrong)...here's some links for you

Well I did google already, but still is over my head when I look at the band settings in the TMO HD2.
If WCDMA = UMTS why is there a separate GSM/WCDMA network selection, both allowing bands in GSM and UMTS.
Sounds like GSM is older tech, meaning 2g, whereas 3g is the newer GSM, which is UMTS, which = WCDMA. Therefore, how can you choose UMTS band frequencies on a old GSM network?
Perhaps I'm not phrasing my question correctly. I'm asking these because of the phone settings. I'm trying to figure out if it's more efficient to just tell the phone to look for specific network/band for TMOUSA thereby saving time and battery.
is this just too simple of a question or not many people understand. anyone?
ok, instead of giving you a bunch of info, let me give you just what I think you need.
I'm guessing you're going to Settings>Wireless Controls> Phone>Band and that's where the confusion is coming from. This screen is wrong and the Bands listed there are wrong (they're from previous devices, and htc didn't bother to update that screen).
So, you have 3 main choices there that should be of interest to you as long as you're in the US on Tmobile's network: Auto, WCDMA, GSM (under Network Type).
Auto: switches automatically between GPRS/EDGE/3G (HSDPA, HSPDA+)
WCDMA: 3G (HSDPA, HSPDA+)
GSM: EDGE/GPRS
The only way that playing with the band frequencies could help you would be if you're just interested in Edge/GPRS since tmobile uses two different frequencies there (native 1900 and 850 roaming). For 3g however, Tmobile uses only (and concurrently....as in you need to use both to get 3g and not just one or the other) 1700/2100 frequency.
Long story short, if you're trying to keep the phone from switching between 3g and Edge and you're in an area that has constant 3g, set it to WCDMA. (but note that if you loose 3g but are in an area with Edge, it will not switch to Edge, it will just be 0 bars/reception).
thanks alot, that really clears it up. I don't have data connection besides mms so I figure I may set it to no 3g and save some battery.
Hi! would someone please tell me if there is a way to find out if I have a
US Model: UMTS850, UMTS1900, UMTS2100
or
AWS Model: UMTS900, UMTS1700, UMTS2100
"System View" app says it is HSDPA 850/1900/2100, but no other app says that kind of info.
I have an unlocked dvp I got from ebay, the seller said twice that it is a UMTS850..., like for at&t,
but
the problem I have is that there is no way I can get 3G signal here in Costa Rica, I have a 3G sim also, with 1MB internet but the phone only gets "Edge" signal for 128kbits/s internet, I have 3G option enabled btw, and I also messed up with EM, and the RF power stuff was set to UMTS 1700, I changed it to 850, setted and that doesn't changed anything.
Tried some test in the tmobile section and some tests say WCDMA disabled or something like that.
Also if someone know a way to force WCDMA / UMTS / HSDPA ?? of enable it?
or set manually frequencies, or know which version I have.
BTW! internet speed works as it should be on a 3g datacard con my pc, but not on the 3 cellphones I tested.
I ordered an unlocked 3g huawei e220 modem and it wont connect at all, I am trying to connect to Bell mobility's 3g network in Canada.After putting the Apn for bell and connecting through the ppp widget , it keeps saying "dialing out" and nothing happens. The modem has a continuos green blinking light too.
Can any one please help me here, I am getting so frustrated with this now
I know it's late but this 3G modem is not compatible with HSPA frequencies in North America.
Specs are:
HSPA on 2100Mhz Band for E220
Edge/GPRS: 850/1900
Bell do not have like Rogers 2G Gprs and have only:
Bell HSPA 850/1900, LTE Band 4 (AWS), Band 7 (2600)
Sorry!
Hi,
I've been going through a lot of posts for this, but I couldn't find a definite answer. Even though Band 40 is supported by D802's hardware(and also shown in the LTE bands in the hidden menu), used along with the Airtel 4G Sim Card(Karnataka, India), I still can't use it because it is disabled by software/firmware? Also, I can see LTE in the Network selection menu. How is it that I can see the Band for LTE(2300 Mhz) used by my carrier but can't use it??
Anybody able to explain this to me would be of great help!
Thanks!

Never mind, I moved on to G4. On a side note, i couldn't get the 2300 Mhz band to work.
Hello
I bought a YD206 and installed russian rom.
It connects to H or H+ 3G network properly. Otherwise, the device does not connect to EDGE.(2g)
AsThe 2g network is complementary for 3g, the device is offline in the shades of 3g network.
Have anybody had same problem before?
I am using congstar, germany. It uses tmobile network. My contract has only 2g and 3g netzs.
The band is,
Name Interface
900 (E-GSM) GSM
1800 (DCS) GSM
Name Interface
B1 (2100) UMTS
I though YD206 has all three band width, doesn't it?
Do I have to set-up some properties?
You need to flash 'chinese' radios:

That is exactly what I was looking for.
Works perfect! Thank you!!!
