WCDMA bands changed on me?

I have a Rogers LG Eve phone (WCDMA bands are 850/1900).
However, I'm not picking up any reception on my provider since I've flashed it to openetna and another 1.6 variant.. Both having the same issue.
I was in the hidden service menu and ran a radio test on the WCDMA 850 and 1900 frequencies, and they said failed, but on 900/2100, they showed success..
Can these frequencies change? and if so, where can I change them back to 850/1900?
Thanks

3G problem in SNS

Hi folks, I using SNS form 4 months. I am not able to see any option related 3G data option in "Mobile Network Settings" screen.
I am in India.
Android Version 2.3.3
My network provider operates GSM Tri-band (GSM 900/1800/1900) or Quad-band (GSM 850/900/1800/1900).
Any additional information also appreciative.

the original model i9020 only works on 1700/2100 for 3G
and quad band for voice
possibly that's why you are unable to get 3G
you might want to sell it and get the AT&T version of SNS that operates on the 850/1900 for 3G

mine is i9020 but it will support for quad band 900 and my network provider is operating at Quad 900. If I am wrong correct me please.

the AT&T version is the I9020A and should work on the proper frequencies. Keep in mind that voice and data use separate bands.

well true

Tri-band HSPA: 900, 2100, 1700

it does suppose to work on 900 for 3G
did you configure the APN settings for your cell phone provider?

By default APN's are configured by network provider. I am getting only EDGE connection. I have tried with *#*#4636#*#* and tried to change preferred network type to "WCDMA only" and "WCDMA Preferred" where default network type is "GSM/CDMA auto". But everything is in vain.
My network provider is Airtel. Any suggestions?

"My network provider operates GSM Tri-band (GSM 900/1800/1900) or Quad-band (GSM 850/900/1800/1900)."
You have given us only the network's GSM bands. Not the 3G ones.
If it DOES support 3G, then check those bands. If it doesn't support 3G, then, well... it's pretty obvious why it doesn't work.

[Q] Using 3g Argentina (Movistar) [WCDMA 850?]

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 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.

Check under settings - mobile network - network mode, set that to wcdma only or wcdma preferred.

i have done thits too, in fact when i put to wcdma only i lose my signal. so i change it again to gsm/wcdma auto.

Try again, after selecting wdcma go to network operators, choose select network automatically or vise versa.

F350S uncompatible in UK

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
