Hi Everybody.
I am currently running simcard modded photon q with Wcdma preferred set under testing-> phone info (*#*#4636#*#*) in germany with gsm/umts/hsdpa provided by o2. I wonder which setting under phone info causes what. Playing around with those settings I experienced different cases. Sometimes I only got gprs (G in statusbar) Sometimes I got no Signal at all or only 3g and no gprs.
On some Settings I got no signal at all.
What I would like to sort out is: what are those settings for, and which one is to prefere in gsm/umts based networks?
Also I experienced different Signal strength between those settings.
All in all I have the feeling the signal strength is weaker then with my old motorola milestone especially in buildings or cars/ busses.
So I want to make sure I've set up all correctly.

WCDMA is on bands 850 / 1900 / 2100 (not on 900!). GSM is quadband, and there is no EDGE.

What does that mean? If set to gum auto pre I won"t have edge, or dose it mean photon q is unable to use edge? So GSM contains all wcdma frequencies plus one additional?

GSM is quadband = bands: 850 / 900 / 1800 / 1900. And the phone doesn't support EDGE, just 2.5G.
Okay thanks for this info already.
So to sort things out GSM auto (PRL) is the way to go here in Germany. Now what is the difference between GSM only and GSM auto (PRL)
GSM only is no 3G. GSM auto is both GSM / UMTS.
After further investigation and considering:
http://de.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System#Situation_in_Deutschland
and
http://de.wikipedia.org/wiki/Global_System_for_Mobile_Communications#Situation_in_Deutschland
I would either lack the 900 band with WCDMA on GSM
or the 2100 band on UMTS.
Or am I reading those frequencytables wrong?
You're absolutely fine with the bands. 2100 for 3G (WCDMA or UMTS-FDD), and 900/1800 for 2.5G.

Okay Thanks for the explanation and info.
Just to make this noob safe:
Using GSM auto (PRL) is the right choice for O2 in Germany?!
Yes.

Go to Start>Settings>Phone>More.
First one should be band selection. Highlight it and press Get settings.
You will be able to select the frequency band.
- Automatic
- GSM 900 / 1800
- GSM 1900
- WCDMA
Select either GSM 900 / 1800 OR GSM 1900 depending on your network carrier.
Last, RTFM.
thx !!
I'm going to buy i780 and just want to make sure I can log into 2G band, 'cos the signal of local 3G provider is really suxk. And FYI, I RTFM already, but it never mentioning the band locking/choosing.....
Last year I bought my Defy in Germany (Vodafone) and over there the 3G connection worked perfectly fine, but I live in Colombia (South America) and my local operator (COMCEL) works only with 2G (GSM) 850/1900 Mhz and 3G 850 Mhz bands. According to the Vodafone Defy's technical features the phone is quadband (850/900/1800/1900 Mhz) but when I turn on the 3G connection in my Defy, the phone loses connection, apparently it only works on 2G bands (data and voice connectios work perfect but extremely slow!). I'd like to know if there's any problem with my Defy, or maybe I should install an other ROM or some patch or plugin to make the 3G connection work?
Thanks for your help!
There's a fix flashable zip in this section for whatever areas your in..

These aren't area fixes, they are fixes for phones from certain areas. A European Defy simply doesn't support 3G 850 MHz so that is a no go in Colombia. Sorry for the TS but that's just the way it is.
The European Defy is indeed quad band for GSM. UMTS is double band at 900 and 2100 MHz.
what is the phone bands in 2g network and what in 3g network ?
thanks !!
I believe these are accurate.
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
You will be able to get 3G on T-Mobile in the US and on European networks, but it will not work on other North American carriers like AT&T, Rogers, Telus, etc. On those networks, you will get standard GSM/EDGE (2G) service.
it has 2100 in 3g for sure ?

Yep. Check out the product specs from the HTC website. Scroll down to the bottom of the page to the section titled Network.

Hi! I've bought this phone (SGH-T959V) from T-Mobile on USA, and when I went to Argentina, I found that the carrier that I have (Movistar) mixes the frequencies or something like that.
It uses GSM 850 / 1900 and UMTS 850 / 1900. By default, my phone can't use 3g (neither HSDPA) from this carrier.
Dialing *#*#197328640#*#* And going to Network Control > Band Selection, I can choose which frequencies to enable / disable.
If I disable GSM 850, and enable all the rest, I can get to use 3g on the 1900 Mhz, but I get much lower signal.
The frequencies that I can enable / disable from this menu are:
GSM 850
GSM 900
FCS 1800
PCS 1900
WCDMA 2100
WCDMA 1700
WCDMA 1900
I don't know how this works, I want to use my phone and be able to use 3g / HSDPA / HSDPA+ / 4g if possible..
I think that I need to find a way to enable WCDMA 850 on my phone.. Is it possible?
I am using the last upgrade from Kies (Gingerbread) 2.3.6
Do I have to flash a new modem? I've searched for available modems for this phone, but none of them say anything about enabling WCDMA 850 frequency
When I go into Settings - Wireless and network - Mobile networks - Network mode it has a GSM/WCDMA (auto mode)
Have you tried that?
Yes, I've tried that, that option is enabled!
In the GL9003L model (Samsung Galaxy S too) from this country, the WCDMA 850 option is enable (also the WCDMA900). Isn't there a way to add that frequency to my phone >.< ?
The hardware doesn't support UMTS 850 which you said is used by your carrier's 4G. You won't be able to use this phone on their 4G network.
Buh, so there's no way to change the frequencies it uses?
Sucks I can't use 3g (not 4g, 3g!!!) on my country
No you won't be able to. According to this page, these are the frequencies available on the phone:
http://www.gsmarena.com/samsung_galaxy_s_4g-3719.php
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
Click to expand...
Click to collapse
Your network will have to be running on exactly those frequenices to get 3G/4G
I think that is wrong.. I have another carrier that works on the 850 / 1900 band and I CAN user their 3g (mostly because I can connect to the 1900 band..), but I can't use HSDPA+.
So:
with one carrier, Movistar, that uses UMTS 850 / 1900 I can't use 3g, it only connects to the EDGE network, and when I dial *#0011# with the GSM bands disabled it says that the 3g service is limited and I can't use it at all.
With the other carrier, Personal, that uses the same bands, I can use 3g on the 1900 band, but can't use HSDPA or the 850 band.
Also, from the #*#*193728640#*#* menu I can choose the UMTS 1900 band.
I've a similar problem the difference is a got 3G but not 4G and can't figure out what is going on. I'm with digicel and the only use 1900 wich is already enabled. I once tried movistar and had the same problem I suggest you another carrier
This's my problem:

Do not trust phonearena as it has wrong information about our device frequencies that it can use.
umts 1700,2100,1900
So basically no, you won't get anything else than edge on those 850/900 frequencies.

So i just bought a LG G PRO 2 checked it everything seemed to work fine
But then i realized the network connection drops every few mins and reconnects only to a G signal (2G)
so upon further investigation i discover that the band frequency on this model is CDMA eg. USA + Canada
To say im P*&^ed off is an understatement clearly the person who sold me this is aware and is now ignoring any contact i try to make with him
I have contacted LG to see if i can possible purchase a motherboard for model D837 or D838 as i see this is my only option to get the device working
Unless anyone here can advise otherwise
Once i go into the band selection screen and disable CDMA bands it seems to sustain a stable connection but only to a 2G network haven't been into a 4G area as of yet to test but it is completely incapable of connection to a 3G frequency within the uk which i will be connected to 80% of the time
not 100% with the F350 but the frequencies for it should be:
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: UMTS 2100 MHz
4G: LTE 850 / 1800 MHz
2G is fine, as UK uses 900/1800.
3G: all UK networks at 2100.
4G: only EE/3 use the 1800MHz frequency. no-one uses 850 in UK.
look around the forum for the secret menu and see if you need to enable 3G/4G manually. or do a manual firmware update.
,My Wife has an F320S (G2)and she can enable all Bands in the Hidden Menu and works fine in Europe in Austria.Network Operator is Three (HG3).
I think the F350S is the same.
Go to Dialer and tipe 5457#*350#
in Modem Settings can you aktivate all Bands what you need
I hope this works for you.
Thanks for the reply guys
There's loads of settings in the hidden menu
I cant see how changing anything in here will help as it is a CDMA device which means it physically does not have the necessary hardware to connect to a 3G network in the UK
As it uses a totally different technology than UMTS
Ive discovered at WCDMA is actually UMTS so i cant see why it doesn't work ?

Those are the default settings that the device is on so no joy with that thanks anyway
using my EE sim signal drops frequently using my daughters O2 sim it seems to sustain a connection but again only to 2G network
Clearly the problem is the WCDMA bands on the device are 850 / 1900 / 2100 while 2100 is used here 900 is the more widely available and thus incompatible with device
I think my only option is to sell it on but to who its no use to anyone in the UK really
