Q: I don't have data anymore

So I recently bought the girlfriend a Samsung Galaxy S 4g. Definitely a bit different than the Evo in terms of the overall process. It didn't help that I started out in the Vibrant forums somehow...
Anyway. As it stands right now I have her phone all rooted and it has CWM and I'm using the Valhalla ROM. The issue is that she doesn't have data.... and when I go into wireless networks and check out the mobile networks and such, I can never actually see T-Mobile. If I search I can see AT&T, which I connect to and I start roaming. If I do this I still don't actually have internet. I can't use the market, or the web browser or facebook or anything that requires data. The browser will sometimes redirect me to some web2go website, otherwise it just times out or says it can't connect to the server.
So does anybody know what's going on? Please let me know if you need any more details.
I've never had trouble like this between my Evo, or my Epic 4g Touch or any friends phones. I've also tried going back to 100% stock unrooted GB and I still have the exact same problem. The ROM doesn't seem to matter, neither does being rooted.

Since you are running Valhalla bring down the notification bar and make sure you have the data toggle on.

Yep, it's definitely toggled to on. I even cycle airplane mode and make sure it's on afterwards.

Only other thing I would suggest is a factory reset. The phone should be picking up the T-mobile network without any problems. But if rooted or not and on stock vs custom rom the issue remains you may just have to set it back to stock and send it in for replacement.
And I know this is a silly question but make sure you call T-mobile and verify that this line has data plan. It has happened in the past when I added a line that it wasn't provisioned correctly and out of the blue the data stopped working. The service was automatically removed due to a reps mistake.

Check your APN settings. Should be T-Mobile's, if not then that's what causing the issue. Just look up for those on google.

My APN settings are correct. I've now tried several other APN settings though, and this hasn't helped.
I know this phone is on a data plan. It's on the $50.00 a month prepaid. It did work when we got it, and after it was rooted. I just noticed recently that it stopped working, and I'm not sure at what point it happened, and if it has anything to do with what I've done.
I called tmobile and they said they couldn't see any network related issues going on. Just my phone not connecting, so it was made a ticket for the engineers I guess haha. They are supposed to work on it, and they usually will either fix it and never contact you, or call you if they need you to do something.

Bump.
I've been in really good service areas with full bars T-Mobile and I still don't have internet. So I really don't know what's up. The "T-Mobile engineers" haven't called me back or fixed anything yet.
I'm about to bring myself back to stock and bring it in to a store.

Bring it back to stock & maybe put it in recovery mode & wipe caches & do factory reset again. See if that helps before returning it.

You might try reflashing the ROM or maybe just flash a different modem. I had issues like that once when i was on black ice. If you had data before, there probably isn't anything wrong with your phone.

Having the same Data problem
I had an unlocked ATT BB Curve on T-Mobile and the data was working (although very slow...)
I decided to try out a "Vibrant" hoping to be able to install ICS via Cyanablahblah.
Searching on Ebay I bought one only it turned out to be the 4G (it didn't realize there was a difference.)
Since then I can't get DATA on the 4G except in WiFi.
On the network it goes to the page: u.web2go.com and says my data plan does not work on this device.
Has anybody had any success with this problem ?
Could it be a 4G issue ? Before DATA came from Edge.

Have you checked what your APN settings should be with the magics of Google?

I have, I've tried 3 different versions with no joy.
Update:
As per T-Mobile Tech,
Apparently Blackberry Data service does not work on non BB phones.

tmob probably caught on that you're using a "4G" phone and will try to force you to upgrade your plan.

Is there any way to fool it with a 3G modem flash or something ?
I think I screwed up when I bought the phone not realizing there were 2 variants of the "Vibrant."
I wonder if I would have this problem with the earlier (non "V") 3g phone.

Probably. If it were just the 3G/4G causing the problem, you can force the SGS4G to only use 2G networks in the data settings... but if it's anything like the old Verizon bits with tethering and other data, they check for specific data strings that are harder to fake... I mean, set.

They use your IMEI to tell what phone it is.

the OP was in 2011, so I'm pretty sure he already got it taken care of

Data not working

Hi all, i have some problems with my sensation: my internet connection works only over wi-fi. When i enable data it doesn't happen anything: in the status bar i don't see the H or the 3G icon and i can't connect. I tried everything but i can't find a solution. I'm using the last build of albinoman's rom and the latest sultan kernel. Anyway i don't think it's kernel or rom related because i went back to stock 3.33 firmware and ruu and mobile connection didn't work either. Can someone help me?

So let me get this straight....your mobile data isn't working on either Albino's CM10.1 ROM or a stock Sense ROM. Is that correct?
Do phone calls work? If they do this isn't a hardware problem because the calls and data use the same hardware. So that's good news.
If all the above is true there are still a couple simple things to try.
First off when you did an RUU was the RUU for Itally or Europe or whatever the geographical region for your phone woudl be? If you RUU'ed back to the North American varient for example and you are in Italy it wouldn't have the correct APN's. So jus tmaking sure of that.
Second, check the APN's (Settings->data (Might have to hit MORE under the data)->mobile netwoks. Access point names). Make sure the APN's are set to whatever they are supposed to be for your carrier. A simple google search should tell you what the APN's are supposed to be.
If that APN is messed up, mobile data won't work.
Third, has this been going on fro a while? Or is this just like a day or two? It's always possible that the problem is with your carrier. It never hurts to call them up and make sure their mobile data network isn't down. It coudld also be a problem with your account. I once fought with my phone for 2 days about the same thing only to find that my carrier had accidentaly removed my data plan from my account. A 2 minute phone call and it was fixed. You can check this yourself by putting your SIM card in any other phone and see if data works on that device.
If none of thsoe work come back with as much detail as possible.

Phone calls work so it's not an hardware issue. Besides when i flashed the 3.33 ruu it was european and the apn is set correctly. I don't know if the problem is that i changed carrier a three days ago. I'll try to see if it's that the culprit

If you changed the carrier at the same time the problem appeared then that is almost certainly the answer. The next question is what to do to fix it.
You could have gotten a bad sim card, or didn't switch to their sim card. Or something relating to the sim card.
Are you sure the carrier has a network that is compatible with the Sensation's mobile data hardware?
Sent from your phone. You should be careful where you leave that thing.

R530U no signal problem... HELP

Okay so I bought this US Cellular S3 from eBay and the phone had network signal when I first got it. Then I thought playing with the Hidden Menu and try to make it work with GSM but all I got is problem. I lost the network signal on my R530U... I have tried flashing couple of stock ROMs but no luck so far. I can see my phone number in Settings > About menu but the network says disconnected.
Please help!

I made the mistake of messing around with the Hidden Menu on my old Samsung Fascinate and it lost data signal. Basically, you may have cleared out some technical string of code related to network authentication ...some ID or something (i don't know) Once its cleared out...no way to reprogram it...far as I was told...had to get it replaced....every phone is different.

Poor cell phone reception with new ROMs

Does anyone here have issues with poor cell phone reception after installing new roms? I have a Razr HD XT926 4.4.2 running a unlocked but stock rom because everytime I go to another rom (I have tried 10+ different roms) I end up getting poor cell phone reception. In my apartment I typically get 2-3 bars on verizon but with new roms I get 0-1 bars and when I am outside I never get more than 2 when I normally get 4+. This is preventing me from using any rom because I absolutely cannot be without reception for work.
All roms install just fine but just this issue. Anyone else have this?
Thanks

Anyone else having this problem? No one?

Hey! So, I came here to try and find some help on this issue or post myself if nothing else. I also have an XT926 4.4.2 with unlocked bootloader on stock rom. I have tried many different roms and personally I love PacRom, but no matter what rom besides stock that I use, I can not get Mobile Data. I haven't checked the cell reception, but the mobile data does not work at all until I wipe and go back to stock. It's really frustrating because I would love to use a different rom other than stock. I do have xposed running on stock, but it can not give me everything a custom rom can. If anyone knows a fix to this, please let us know!

Do you mean like changing all the settings and apns in there? And hitting that checkbox? Yeah it works on stock, but it does not do anything on a custom rom. I have calling and texting, but no mobile data.

Yes going into that screen. Idk if there is a difference between Verizon account types, but i know for me over on the AHD and on ATT, I need to be set to ATT phone b/c i'm on a prepaid account to get data to work instead of ATT LTE

yes, not as extreme as you, but from what I've read along the way its common to all AOSP roms. My battery life is noticeably worse because its searching for signal.

Hmm... I am on stock at the moment, but I will go to a custom rom for a bit again probably tomorrow to mess around with the settings again. Either way I will post what I tried and possibly screenshots for maybe more help on my part or to help others if they have the same situation. I just have no idea what needs to be changed. I tried copying the apn settings from stock, but that didn't seem to work. Maybe I did something wrong or missed a step or something. I'll be back tomorrow. Thanks!

Mobile networks drops out after android 7 upgrade

Note 5. Android 6 to 7 update. It said an update was available so I did it. My mobile network drops out. Can't text. If I make a phone call it comes back up. I have done a factory reset since the update to attempt to fix it. I did not have this issue until doing this upgrade. I do have the stock 6.0 ROM. I'm almost to the point of loading it back in if I can't fix this. Also my 4g LTE signal is good even when it says cannot find mobile networks.

Have you made sure your Network Settings are correct?
So you have APN settings? Have you verified they are set correctly?
I DO NOT PROVIDE HELP IN PERSONAL MESSAGE, I DO NOT TAKE REQUESTS IN PERSONAL MESSAGE, YOU WILL BE IGNORED. KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

The APN can't be changed. It's shaded. I don't know how it could be wrong. I find it odd that placing a call makes everything work again.

Yeah, that's strange. You would probably have better luck looking around and also asking in the Note 5 forum for your device model.
