When on 3g, data doesn't work?

I almost always have data on edge, except when its below two bars. Now when ever i get more signal then edge, it switches to 3g...the problem is that I get only about 2 bars of 3g inside buildings, and I never have data working at that point, not edge. I have no way to turn off 3g as I dont have the option in any setting.
What should I do I can't take this anymore. By the way I'm runing custom rom froyo.
Thanks for all the help, danny

What rom are you running? I've not seen a rom that doesn't have that option under Mobile Networks (WCDMA/GSM). GSM would be EDGE and WCDMA would be the 3G option.

3g on tmous tab on att

Popped my sim back into my tab which is flashed to make phone calls and I got hsdpa on att. Made a google search. Loaded it very quickly then kicked me off the network. Had to reboot to get back back on. So does that possibly mean that its att and not the t mous tabs that's keeping them from getting 3g.
I have data roaming off so no chance of wandering to diff network

Try uninstalling juice defender. Juice defender has a problem where it starts making its own decisions and disabling/enabling mobile data whenever it feels needed. I dont think its an att problem. When you rebooted, did u lose connection to the network again after a while?

No its a t mous tab on atts 3g network. That's not supposed to exist

Sorry I didn't clarify that. Just wondering if anyone else has seen hsdpa on their tmous tab on att

Usually flashing to stock fixes all issues. I would suggest doing that and recustomizing to your needs and seeing if the problem arrives.

Yes by flashing your tab to be able to make phone calls, that means you flash it with a european rom. Your tab turns into a european tab and att use the same band as europe for 3G data. That's why you have 3g and phone capability.
Here's what haopens when I put my sim in.
Keep in mind its a t mobile tab
Tab starts
Tab finds att gets on att network
Tab then picks up hsdpa from att
Tab does google search and then is promptly kicked off the network. Have to restart tab to get back on network.
After restart tab then finds att and edge only. Should I constantly have hsdpa on the flashed. Tmous tab on atts network or is getting it on start up a fluke.

K dialed *#0011# and the tab is definiately getting 3g. Its on wcdma 850 at -105. But the h refuses to appear next to the bars.

It depends on the signal strength. You won't always get H sign, sometimes one meter can make a difference it depends on the place where you are.

T-Mobile TAB hardware supports AWS band (2100 down 1700 Up) for 3G. AT&T 3G is 850/1900.
Here is what is happening in your TAB. You have an AT&T SIM in a TMobile Tab. I find's TMO 3G network but is unable to connect since you have a AT&T SIM.
Obviously you cannot connect to AT&T 3G network because your TAB cannot connect to AT&T 3G bands.
no doubt, the OP is liar! the picture is actual att tab , not tmo one.
I own both att and tmo tab.
tmo tab has no way to get att 3G with any modem (include att one).

It is a fact that you will not get AT&T 3G on the T-Mobile Tab or vise versa. They use different bands. So the hardware won't allow it, which can't be fixed by flashing a different ROM no matter what.
Or by flashing a different modem either!

Nexus s 3g is not working in india

Hi I bought my nexus s i9020t from bestbuy 4 months ago. I am ftom india, I am not able to receive 3g signal in india and they say this is because of my mkbile is not compatable. Please help in thus regard, egat shiuld I do to get 3g.
Sent from my Nexus S using XDA App
The basebands for 3g are different in india. The i9020t comes with the 9020 baseband i think if you flash the 9023 baseband with the KD1 radio, Your 3g will work. I got my i9020t nexus from the US and am using it in india. I had a motherboard problem and got my motherboard replaced from samsung here. So they changed my baseband , Hence my 3g is working now.
I used my 9020 with vodaphone and got 3g in new Delhi. I was on vacation

I use the i9020T and I have no problems whatsoever with my 3G signal. Get speeds close to 4Mbps. I´m on BSNL Andhra Pradesh.
Which service provider? Maybe your service provider does not provide 3G in your area?
Or try this -- Go to Dialer and type *#*#4636#*#*
After that tap on Phone Information. In Set Preferred Network select WCDMA only. That´ll give you only 3G signal if available. If you want to go back to 2G select GSM only. If you want both select WCDMA Preferred but this is a huge battery drain.
Hi please give me little more insight to what you have done. Where are you from india. I am in bangalore can you pkease provide me some contact numbers of customer care. Can I directly flash 9023 rom into my mobile? Or will there be any hardware incompatibilities? Please help me I am dying to activate 3g

Do NOT flash the 9023 ROM. That could make many things go wrong. If you're APN settings are configured then do what I said above and you'll have 3G.
Hi anirudh thank you very much for your reply I have already done that but it is of no help. Please educate me littme moe in this regard
Sent from my Nexus S using XDA App
Maybe you send some sort of msg to get 3g activated. For airtel you've to send "activate 3g" to 121. Maybe Vodafone has something of the sort too.
Hi anirudh in my mobile I have already done that so mobile connection is 3g active. Can yiu please give me your number

Frequent disconnection on Vodafone
Anyone facing frequent 3G disconnection on Vodafone network? I have 9020T and have KD1, what radio are you using?
That's the T-Mobile version. The Nexus S is not a quintaband phone. Tmobile 's 3G is 1700mhz band. So I do not believe you will be getting 3G with that phone in India.

I was getting 3G connection with Airtel/Tata Docomo all this while. Now i moved to Vodafone and suddenly it stopped. Moreover, i am getting 3G connections and can access data as well, but it automatically disconnects after a while like 20-30 mins.
This is working now after changing the sim from the same operator. In case someone is facing the same problem, talk to ur operator and get ur sim replaced.

4.4 and Non-VZW carriers

These issues apply to T-Mobile users installing the current build of 4.4 (and possibly other GSM carriers but I don't have an ATT SIM to test). Motorola is aware of the issue. I read these forums pretty thoroughly and I've been answering these questions all over so I figured I'd just put them all one place. Issues as follows:
- Devices with the LTE radio active cannot send SMS
- Devices with the LTE radio active cannot send MMS (Carrier/Settings dependent)
- Devices with the LTE radio active cannot make phone calls and instantly disconnects on call attempt.
Urban Legends:
- Stock tethering does not work - I have personally tested on TMO and know it does work. Yer doin' it wrong.
Fixes
Easiest fix for now if you're on a device running 4.4 and want to... you know... be able to use your phone... is to use phone information and switch the radio mode over to GSM Only (not the auto one). This fix is a little finicky because if the phone realizes it's not running in the mode selected on your mobile networks screen it will override and turn LTE back on if you haven't selected UMTS only.
Full steps are:
Mobile network settings - Change network mode to LTE/GSM/UMTS
Mobile network settings - Select network UMTS Only
Install app linked below
Open Phone Info and select GSM Only
Phone info apk for sideload - http://www.mediafire.com/download/284l17ry2ok1yuk/Phone_info_1.3.apk
I'll update this thread as I discover more issues or as people post issues that can be replicated below.
Thank you. Finally I got the LTE turn off.
I gotta switch the mobile mode to LTE/UMTS/ gsm and select network as UMTS only. Then use phone info choose gsm only.

It was selecting GSM Only in Phone Info. Switched it to GSM auto (PRL) and I got HSPA+ back.
but Seriously dude. thanks for this info. I was tired of using my Moto G while my MAXX was just collecting Dust.
Edited the OP for a more clear fix. Thank you to vuphongkkk for pointing out the UMTS only.
I'm on T-Mobile and live in an HSPA+ refarmed area (NYC), but there are places I go on a regular basis that aren't refarmed. I set it on "WCDMA preferred" and voila, I have both 2 & 3G connectivity, with preference given to 3G.
I can't post links, but this XDA thread explains it in more detail I think: ... showthread.php?t=688492
Vodafone confirmed for anyone wondering.
H+ for UMTS only,
Edge for global.
No Sim adjusting at all
Just popped a sim in today. Getting LTE but really hating the call fail bug. Gotta place the call twice repeatedly to get it through
Maxx'd out Kit Kat
Update: Having major glitches when running LTE, pretty deal breaking for a full switch to tmo right now. Eagerly awaiting the new OTA to see if it fixes it. Seems to have major issues on the HSPA/LTE handoff. How did it function prior to 4.4?
Maxx'd out Kit Kat
On 4.2.2 was working fine, the phone just switch from LTE to 3g itself when you need to make phone call. But I had problem on 4.2.2 that if I connect to WiFi then it'll take awhile to get the LTE back. Normally an hour after out of WiFi range

Maybe thats the problem I was having? I just ended up with a 4.2.2 phone after my 4.4 got destroyed. LTE wouldnt work for me but I was in the house after switching off wifi...hmmm
Arcanexvi what's the best APN to use for 4.2.2? And do I have to have phone info installed or can I uninstall it? Since I changed all the settings to get hspa+ I forgot what the default settings were. =\ whoops and thanks for all your help so far

You can uninstall it if you want. It's extremely small though so no reason to do so unless you just don't want to see the icon. Uninstalling will NOT reset your settings.

Thanks! I messed myself all up though.
In android mobile network settings should I have network mode as global, LTE/CDMA or LTE/gsm/umts?
If its LTE/gsm/umts do I still use gsm only under select network?
And if I leave phone info installed do I have to change anything on there for LTE to work? Phone info seems to change the network selection in the app on its own so I just stopped messing with it. Thanks and sorry to be a pain

If you on 4.4 you don't have to change anything to have LTE work on your phone. Follow step by step from the beginning of the thread to turn off LTE

I'm on 4.2.2 and already changed settings. So was curious on what the original settings on 4.2.2 are to get LTE working with APN settings
Sent from my XT1080 using xda app-developers app
4.2.2 rarely get LTE data. Choose network mode as LTE/gsm/UMTS . select network as automatic. Don't use the phone info. If you already use the phone info app in this thread then use it again to switch back to LTE/gsm.. Or the option that has evething.
Remember to add APN fast.t-mobile.com
But as I mentioned, 4.2.2 has some problem with the radio , so it rarely pick up LTE

Just to add another data point, I have a Droid Mini on stock 4.2.2. I'm connecting to t-mobile with the listed apn info, global and auto. I have LTE the vast majority of the time.
Cheers!

[Q] No 3G signal

So I just got my Note 3 SM N900 a few weeks ago. However the signal received was very weak, so I used Odin to flash a new modem (DXUBMI1, as demonstrated in this thread http://forum.xda-developers.com/showthread.php?t=2475714).
After flashing, the voice call and SMS were more stable, I constantly got -51dbm in signal strength. Yet in terms of network connection I could only connect via EDGE (2G). When rebooting, the phone could connect to HSDPA (3G) initially, but after a while, it drops 3G and turns to 2G again, hence I believe the problem is not with the service provider.
Please see the screenshots for more details. My questions are: how do I improve connectivity and are there any other better modem base band to flash on my Note 3 (I bought the phone and currently live in Vietnam).
Appreciate your help. Thanks.
Just edit out your IMEI Number from that screen shot first - keep that number to yourself always.
Do you have a case on the phone? Or a bumper?

I forced it to WCDMA only and got 3G for a while...then the signal just went out altogether. The phone signal only came back after I switched back to WCDMA/EDGE auto select.
Is there any chance this problem is hardware related?
It is possible that it is hardware yes. However. . For some bizarre reason it may be the case.. take it off and see how it performs then you can reassess
