[Q] Please Help!!!Good signal connected to HSPAP but no Data

Hello, thank you in advance for whatever help you can give me. I purchased the AT&T galaxy s4 and I am trying to use it in Colombia with my provider Tigo which runs on 1900mhz but I have problems connecting to the internet.
This is my second galaxy s4, the first one I had I opened the AWS bands, selected WCDMA/GSM Mode Only on the service menu and my internet was working just fine. Unfortunately I lost my first phone and bought another one, and went through the same procedures but my mobile data is not working for the most part while it is connected to HSPAP.
If I select GSM only on the srvice menu then it navigates, but at 2G speeds. What seems strange is that I am getting great signal and when I go to about device/status, it shows it is connected to hspap, and gprs, but I dont have an internet connection except at a couple of places, for some reason when I am in my house it works (wifi off), but when I leave my house it doesnt work.
If you have had a similar problem an were able to figure it out I will appreciate any thoughts you may have. It is frustrating having this phone and not being able to use the internet.
Thank you.

[Q] RARE no WCDMA or 3G conection at all

Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.
I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.
Searching the net, i came over this:
Nexus 4 Suffering from 3G and 4.ยท Upgrade
And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.
Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?
And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?
And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...
One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all.
Really annoyed with this, hope someone is able to help me with this.
Thanks to all in advance.
Nobody? well i will try to find out myself.
Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.

[Request] I9506 Modems

Hello
I live in Romania and own a I9506 from other country and in some poor signal areas the phone loses signal and emergency calls only appears while other i9505 holds the signal from same carrier (Orange Romania).
I would like if someone would help with a few modems to try and see if there is a difference in the signal quality.
Thanks in advance
Adrian
So ... it seems that this device lacks the support ... Pitty for a device this powerful ... Wil sell and buy something else
Well you can extract modems by yourself. Just download the software you want and extract it with 7zip.
We don't know what's you're on now.

Just flashed the nordic rom... will post if it works or not. thanks all
Ok so the problem is this ... The phone does not connect to network on gsm mode ... if it's on auto lte/wcdma/gsm it works on wcdma. If i select gsm only it does not connect to network. On manual search it all goes ok finds all networks but when I sellect my carrier it says registering on network for about 3-5 mins and after that can't register to network error. On other phone it registers with edge speed.
What can I try ???

Problems with N900A LTE Signal

Hello everyone: I hope I'm not breaking any rules by posting this, but I'm having annoying problems with my handset since I updated the OS to Lollipop N900AUCUEOC1. My handset is SIM unlocked and use it here in my country Peru, South America. The problem is as follows, it is most of the time with only 3 signal bars of LTE, the handset must outside to get full bars, but the real problem is that sometimes it doesn't get any connection at all (pic attached), most of the time happens right after I disconnect from my house's WIFI, or sometimes, it only connects to H+(4G), I have to dial *#2263# and change it to any option and then, set it back to LTE/GSM to gain access to the LTE Signal, and I do this everytime I lose LTE signal, I must tell the phone to use LTE instead H+ o get the signal back. I think there is a set of numbers somewhere that I can manipulate and tell the phone that LTE signal is available always and stop losing signal. I little story to understand my predicament, when I bought it it I had the same problems, and I took it to a guy who did something to the handset and worked perfectly ever since, he told me he "recalibrated" the signal settings. But after upgrating it to Lollipop, the problems came back. And the guy is no longer where I remember I found him.
Thank you in advance for your help, I really appreciate it.:fingers-crossed:
If you have questions or need more info, I'll be happy to provide it.
Hello,
Try to enter in Settings -> Mobile Networks -> and choose the Prefered Network to the mode you want!
**You're not breaking any rules, you are just asking for help! XDA is exactly for that!**
(I'm using an unofficial and modified CM13 by TEMASEK, so this steps is in AOSP settings app, but I think that is almost the same thing in TouchWiz)
Try this and tell if it works! ^.^
Sorry about my english, I'm brazilian...
