Good morning,
I have an Xperia Z5(E6603) which is unlocked. I live in Dominican Republic so I use the 900 MHz for 3G connection.
I accidentally went into *#*#4636#*#* > Phone Information > "..." > Select radio band while testing something and selected "USA Band" which does not have the 900 MHz for 3G. Now my phone only works on 2G or LTE(which this last one does not have so much coverage on my country).
"USA Band" was the only option I had and its still the same.
Is there a way to fix this?
Thank you very much in advance.

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
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.
hello guys!

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.

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

Just sold on ebay for £165 but its to someone in brazil with 4 feedback
Just missed it.
It's back up as the winner was obviously a scammer
I got this korean version of lg g2 320s. This is for the SK Telecom carrier in S Korea. When I use this in India, I am able to use only gprs on this. I have tried setting the apns manually but not able to get 2G or 3G to work.
When i go to network settings it shows only 2 options for Network Mode. first is LTE preferred and second is 3G only. My carrier Idea says i need to select wcdma which i don't see.
I went thru some forums before posting here and tried 5457#*320# i tried changing band selection but still my device wont get 2G or 3G signal.
Then I thought this problem may be because of the OS, so I rooted my phone and installed Cynogenmod 12 custom Lollipop ROM for my phone.
Now I see following options to select for the preferred network type:
WCDMA preferred
GSM only
WCDMA only
GSM auto(PRL)
CDMA auto(PRL)
In spite of selecting WCDMA preferred my phone shows network type as "GPRS". I tried changing the bands but it also didn't help.
These are the bands I see in radio switcher.
Euro Band (GSM-900/DCS-1800/WCDMA-IMT-2000)
USA Band (GSM-850/PCS-1900/WCDMA-850/WCDMA-PCS-1900)
For India following networks a re supported.
2G capabilities -- GSM 900, GSM 1800
3G capabilities - UMTS 2100
4G capabilities - LTE 1800, LTE 2300
It would be great if you can guide me to the right forum to get some pointers
Thanks in advance.
