3uk Android on Kaiser Problems

Hi
I'm running android on my Kaiser, from Nand and I'm on 3-UK
The problem I'm having is that the 3g signal where I live is really bad - so bad I have to disable it in windows mobile or all I get is constant flicking between 2g GPRS and 3g
I have tried the setting on the android through the settings - wireless - mobile networks but the 2g only won't stay checked.
I have tried the *#*#INFO#*#* menu setting and it always reverts back to WCDMA preferred.
Both of these can only be changed when the phone finally locks on to a signal.
Now 2g will always show as roaming, I think because 3-uk's 2g is on Orange, in windows it still shows as 3 but on android I get the following:
2G: Orange PCS Ltd
3G: [email protected]
My phone is originally an orange kaiser but has been unlocked and hard spl'd
Really frustratingly if I run Android via Haret from Windows mobile (where I've forced it 2G) it runs fine.
Can anyone here on 3g help ?
Anyone help ?

How do I select UMTS/WCDMA mode only?

Well guys I am a newbie to the Android world!!
On my earlier Nokia I used to have three options for the Network Mode under the Phone Settings, viz. , Dual Mode, UMTS, GSM. Since in my area the 3G signal is a bit weak I used to select UMTS only, so that the phone doesn't switch over to 2G automatically.
However, in my android device (Samsung GT-I5503) the only option under the Mobile Networks which is anything similar to a Network Mode selection is the Use Only 2G networks checkbox. I believe it disables Dual Mode and allows GSM network only, in the Android device. So Android Gurus and Forum Moderators, do you guys know of any method or software which can select 3G network only!!
Please help me guys as the 3G reception in my network is a bit weak, Android doesn't switch over to 3G!!
Oh and BTW, I'm getting a really good 2G signal. The Signal Bar is 4/4 most of the time!!
@Mods: Could you please change the title of the thread to "How do I select UMTS/WCDMA only, on Samsung Galaxy 5 (GT-I5503)?"

[Q] can't switch to 3G :'(

Hi all
I've got a problem with my Verizon S III device
I live in a country that doesn't have any 4G networks ( 3G only )
so i went to "settings">"more settings">"mobile networks">"network mode"
there i tried these:
Global witch doesn't connect to 3G
LTE/CDMA witch gave me that my SIM have "no service"
GSM/UMTS witch didn't connect to 3G also
so if anyone would help me on how to connect to 3G network I'd appreciate it

[Q] SIM MODded Photon Q 4G LTE issue with GSM

Hi guys,
I normally am not a big responder or thread creator here.. Just a happy Photon Q user … but now I am looking for your help!
I own a Photon Q modded by CornholioGSM. Worked like a charm untill I got on a plane last week. (From Netherlands to Italy)..
When boarding I set the phone to flight mode.
Got off the plane and switched it back on, turned off flight mode. No longer acquiring connectivity to mobile network.
So.. went into Android testing (*#*#4636#*#*), turned Radio Off and set it to GSM Auto. Turned Radio back on.. still nothing.
Went into settings.. Mobile Networks > Network Mode was suddenly changed into “Global” and could not change it into anything else.
Factory Reset the device, again set it to GSM Auto and Network Mode was now changeable.
Set it to all kinds of different settings but it still won’t connect to a mobile network.
Everything else on the phone works fine except mobile networks. So no GSM, EDGE, 3G etc. WiFi does work.
The SIM card is also detected and eg. Whatsapp works fine too.
Does anyone know how to solve this?
Do I have to reconfigure the device or perhaps try a different ROM?
Any help will be greatly appreciated!
Grazie,
Steve McQueen

Photon Q &/or Note 3 on ting.com
Thnx for your reply RBeavers!
I did consult the SIM MOD thread.. My issue is a bit different though.. My Q has no network connectivity anymore.. at all.
It doesn't drop sometimes and then reboot to fix.
Btw: Its running stock ROM. Might be worth to mention that
Hope someone can help!
Hmmm just installed CM 10.2 .. Set the band to 800/900/1800/1900 .. Set Phone testing to GSM Auto.
Mobile Networks to connectivity to GSM/WCDMA Preferred.
Still outta luck.
Can't think of anything else other than a wire has come loose.

Maybe it's something like this?

Also, getting radio log (as soon as possible after boot) could help to diagnose the issue:
Code:
adb logcat -b radio
Happy days!!
Got it working with CM10.2!! Fiddling around with it. Set band to Automatic, *#*#4636#*#* GSM Auto, Settings > Mobile Settings > Preferred Network Mode: GSM Only
And set Use Only 2G checkbox. Magic.
These settings in the stock ROM wouldn't work anymore.
Thread can be closed. Thnx everyone for reading and replying!

Network Mode LTE reduce signal

Hi,
I'm having some really annoying issue with my phone, when I select the Network Mode to GSM/WCDMA (auto connect) it is working perfectly fine but as soon as I change to LTE/GSM/WCDMA (auto connect) I lost 75% of my signal.
Of course without activating LTE I cannot access the 4G Network which is a bit annoying.
I also tried to flash the latest modem for my phone g920i but it didn't solve the problem.
Any idea would be greatly appreciated.
Thanks
Maybe it is caused by your carrier?
Check mine... its normal
Same issue with my S6 on Telus in Canada. Loses cell signal when stet to LTE or wcmda at times.
That's normal

This is because cellular repeater is a bit far from you try this app https://play.google.com/store/apps/details?id=com.staircase3.opensignal to see where it is. You will notice this happens also when you enable LTE/GSM/WCDMA and there is no LTE signal your phone will go in 3G mode (or H,H+, etc..) and the signal indicator will change. Sorry for my bad english if i made mistakes, I hope I was helpful.
