Got a problem , hope you guys can help.
My my mobile data won't work on anything less than HCDMA, but when I set this my phone signal drops to 1 bar or less!
If I set it to gsm my signal goes full but no data!
I have rooted and installed a insecure kernel /rom as below .... worked fine for a few months.
Model number : GT-I9300
Android version : 4.0.4
Baseband version : I93000VLG1
Kernel version :
3.0.15-928452-user

Is there a chance you are on 3 UK?
Afaik, as their name indicates, they only provide 3G/HSPA coverage and no 2G coverage.
3G uses higher frequencies which means more throughput but less distance so it's normal that the signal is weaker than when using 2G networks.
It's also less resiliant to distortion and other signal issues.
You might want to check into using a 3G repeater if the issue occurs at home but be warned that the usage of these devices is shady at best and illegal in most countries. (You'd need an official license to broadcast at that spectrum even if it never reaches across your own borders)

Hi! Flashing a modem might help you out on that problem.
I hope this helps

no problem. do leave a feedback!
kernels are for wifi connections
modems are for network connections like your signal
Try calling your carrier and ask them to refresh your network and APN setting. I suffered this problem yesterday and called my carrier five times to deal with it. Now it is running fine.

Thanks guys for both of your suggestions, I did change my modem and I did ring Vodafone to refresh.
The modem did improve the signal slightly but the refresh has resumed normal service!
At least I now know how to change or tweak my modem for optimum performance. Also did not know the kernel was for WiFi.....will look at that too!

One strange thing though...only works on edge....anything higher it just hangs.
Sent from my GT-I9300 using xda app-developers app
As i find and as others have posted .
If you have changed modems and get problems after reflash to a known good modem .
Then one solution is to start from scratch wipe phone and install older stock firmware .
Then update .

You are most welcome

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

Washington D.C. has no GSM coverage inside the tunnels. Only some stations have coverage. Only Verizon and Sprint with CDMA devices have service on moving trains.

You can flash DXLF3.. It works so much better than the LFB radio.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...
Hi
Really weird problem my s3 has Been working fine until I woke up this morning and it is showing no mobile network but allows data connection still but not able to make any calls.

Right I turned it off took the SIM out booted back up without SIM the rebooted again with SIM but the signal still keeps dropping off I only get signal for a few seconds. I normal get really good signal where I am. Also battery is dropping quicker then normal I guess that's down to searching for signal though

I'm having a very similar problem on my UK handset on orange running latest jellybean Rom.
There are times when I am trying to load an internet page or xda subscribed thread for example and the phone shows full signal and the data is switching between 3g and h+ on and off and the arrows show nothing happening or data transfer.
I normally end up exiting the page/app and restarting it.
Is this a modem problem? Do I need to flash a different one?

Search the thread for a modem of your region and try a few till you get one to your liking. Takes a while for the phone to get 'used' to a new modem so even if it isn't the best at first, the signal tends to improve after about a day or so. I have never encountered problems with signal but I hope this helps

ST runs on the t-mobile network. You need to flash a compatible modem.

Straight talk runs on either. Depends on your area. You're most likely at&t seeing as 90% of straight talk is.
Straight Talk leases their services. The reason it's slow, it's NOT hspa. It's 3G and that's most likely the best you'll get.

OP, are you being throttled? Seems ST possibly throttles on 100MB a day and 2GB a month. That would leave you with H+ and horrible speeds. Contact ST and ask them to reset your network.
They used to throttle me ALL THE TIME! Good price but **** service. Went back to AT&T so I can use MY data how I pay to use it, not how they want me to.

Flashing a modem is easier than flashing a rom. Get the modem.bin on your sd card, boot into recovery, flash the modem.bin using CWM/TWRP (no wiping needed), reboot, check for correct APN settings (some roms don't include APN settings).
Im sorry bear with me ranger but can u go a li little more in depth for me where do I get that modem. bin

If you have really slow speeds then you are either being throttled or you are not filling in the APN correctly. Does not sound like a modem issue. What speed does your notification bar show you connected as? How about settings > about phone > status >Mobile Network Type: ?

How about a screenshot of the status page in settings? APN looks good. Speed test sure looks like you are throttled. For chit and giggles try removing the proxy and port from the APN and see what you get. Not the MMS proxy and port.
