I have search all thread/forums/questions and I didn't found anything similar. Some threads says cause is old SIM card, lemon phone batch and TMO network issue. Not sure where this will fit.
Just want to share this info, be gentle noob here, New TMO customer/new phone
I got my htc sensation few days ago and root it on Stock ROM then install a bunch of apps and freezed a couple apps(aka bloatware) using titanium backup pro. After 3 days I lost all data connection (gprs/2g/3g/4g) except WIFI of course.
Called TMO-US they said that they reset my network and we do a whole bunch of troubleshooting. Still no luck but when I Tried using my sim card on my old phone(HTC inspire) I got a FULL 4g/network signal. WHOA!!!!
I didnt give up because htc sensation is a beast! but after spending alot of hours searching for the fix , no luck... then I decided to let the phone go since Im still covered my the 30 day grace period. Upon looking for a different phone on TMO lineup can't find any phone that can beat the htc sensation. So I resort to getting the same phone replacement.
*****Trust me I've tried everything that this sita has to offer (radio/cipher boot, airplane mode, battery pull, config settings)****
Then this whole fiasco becomes interesting...
Got the instructions to "de brand" the phone. S-off and unroot.
Downloaded stock rom and install it. on first boot 4G icon popped up.. hmmm... tried to browse the net and download some apps on the market check
so I download htc software updates(using 4G), reroot the phone and restore my backup.
I assume the cause is somewhere along the line of
- installing stray apps and freezing bloatwares - (not sure which one- too many to know) or
- some rogue processes triggered the data connection lost or
- need to do htc update first before roorting or
- I just got a freak accident upon rooting.
Doesn't matter I got my data connection back. So far so good.....
HTC Sensation
Stock ROM, S-OFF, Rooted
i had a very very similar problem as yours.
before I was s-off/rooted it was running fine with 3g over in asia. zero problems with the stock rom. started reading on s-off for about a week and went into Insertcoin cos that seem like the most popular.
after rooting to insert coin, problems started ... i could hardly get any 3g network even though the icon showed there was data going in and out. flashed from IC 2.2.5 to 2.2.7 and thought it would work itself out, 2.2.7 to 2.3.0 didn't work as well. Gave up and jumped to ARHD and every thing worked
It looks like both Insertcoin and ARHD uses two different kernels/radios. IC works on TMOUS for majority of the users, so you might want to look at InsertCoin and try that out on your 4G set
This is getting more interesting.. .As Im planning to venture to try different roms.
I'll keep that in mind and yes indeed InsertCoin is more popular.

Any advantage using InsertCoin? Because for now Im happy with my set up HTC sense is a bit laggy but not all the time and speedtest says 6mb++ download : 3mb++ upload.
if you're with tmobile & the your data worked with another phone & not the Sensation, your IMEI was probably blacklisted if you don't have and "Android Approved" data plan according to tmobile.
When the phone first came out a lot of us were having that problem. Our data would work for a few days & then would stop completely. I was running the original Total Internet plan from back when the MDA was release & it shut off. Tmobile didn't remove the flag until I converted over to an android plan.
My guess is you're on an older data plan & they want you to switch to their throttled data plan
Thanks for the info Xnifex! I'll keep that in mind, Im not sure though what you mean by "Android Approved".
Since Im a new customer with a new phone(HTC sensation that came from them). Im positive its brand new not refurbished so I assume IMEI is good.
I lost the data 3 days after I rooted the phone with S-OFF and SuperCID and a few tweaks. but I got the data back when Im in the process of de-branding (unroot and S-ON)
Although I didn't reach the S-ON process because I got the data back after installing the stock ROM/RUU. So I reroot it again.
The only thing I can remember on TMO side is the tech rep told me that they reset my data connection not sure if that helps
So far no issues here
If you lose connection again, call tmobile and make sure that they have you on an android data plan. I had a winmo phone before my sensation and they have 2 different kinds of data plans. Not sure why. My data stopped working after a couple of days. I had to call support and have them switch it away from the winmo data to the android. They might have screwed it up when you signed up.
the android approved was in quotes because it's no different than any other plan, but it's the term they use to get those that were on older non-throttled plans to switch over.
If you're a new tmobile customer than I don't know what's wrong, but if you're an older one who had a data plan from an old blackberry, windows mobile, or other smartphone, they blacklisted your Sensation IMEI until you switched over. That's probably why you could get it to work on a previous phone, which wasn't blacklisted, & not the Sensation
HMMMM... Almost the same scenario as I suspect.
Thanks for all the inputs.
All I can remember on tmous side is they reset my connection and I forgot to mention on the earlier post that I have my att number ported into tmous, probably thats the cause.
But I assume its the phone because after all the things that tmous have done I waited a couple of days nothing happen.. the only way I get the data connection is instaliing the srock rom\RUU.
Its been 5 days now, I've install the same apps that I got before and freeze a few bloats.. Still got data connection. Happy camper here...
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.
Needs Add on Data plan

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

No you shouldn't have. :good:
I have a TMo nexus s, which has been shoehorned on to AT&T GoPhone since I came back up to Alaska. No data, which isn't a problem (its the wrong 3G bands anyway). Three days ago it emptied my account as normal, stopped working like it always does. But wait. I immediately got data service. Its EDGE, but its full. I can even tether. No calls or texts, as expected since my account is empty. But as much data as I care to use at edge speeds for the last three days. I haven't changed anything on my phone in months. Its running an ancient nscollab rom based on gingerbread. I'm not sure what's happening, but I'm holding off on a reup just to see. Anyone have any ideas what's going on?
well lets start with the basics.
check your apn and see if it is the same as the carrier youre on.
settings-mobile network-apn
try restarting the phone and take out the battery for a minute or so.
updating rom.
is there anything else you can say to help me understand more?
I ditched Verizon and went with T-Mobile pre-paid, only 2G data but its a temporary solution and I get service for 3 phones for $90.00 a month.
I so far have a stock t-mobile rom installed, android 4.1.2 with no porting needed and wireless calling and other such bells and whistles work just fine.
Now my next step is I would like to install a T-Mobile radio to complete the scene. Would this brick my phone? Or perhaps delete my IMEI?
How can I back my IMEI up, or any other sensitive info for that matter?
I know I may be chasing a dream but I am still trying to make HSPA data work on this phone with T-Mobile. Chances are slim but if I pull it off I can be somebody for 15 minutes. . I am in an area where every possible T-Mobile spectrum is floating around in the airwaves since they purchased MetroPCS.
Thanks in advance for any help and/or advice. I am working 16 hour shifts for a couple of days so I will be slow responding.

Flashing any modem except verizon and you stand a 99% chance of bricking your phone.
Rrason being is each provider has the radio hardware built to their specs/ system. Put different firmware in there and you have a brick.

Hi everyone - I have a Verizon S3 that I use without any trouble here in the UK. My network (Three Mobile) will soon be turning on their 4G system, and everyone with a 4G device will be able to use it - including me. The only problem is that in order to use 4G you need an OTA update - whether this update is an actual firmware update or just changes to the APN settings, Three don't seem to want to tell me (or more likely, the Three reps don't know).
This OTA update is only going to be sent to Three branded phones and unbranded phones - meaning my Verizon S3 isn't going to get 4G enabled if I leave it as it is.
What I'm wondering, is if there's a way to load the Verizon S3 4G LTE with a standard Samsung ROM that's totally unbranded. That way I should be able to get Three's update and use 4G.
I'm new to this, and I've never flashed a phone before - all Google seems to bring up is Cyanogenmod, but I think that's a bit more custom than I want - I'm looking for something totally vanilla minus the Verizon junk. Can anyone help point me in the right direction? And has anyone used a flashed Verizon S3 in Europe?
Thanks a bunch,
Noam
Would CleanRom 7 work for this? scottsroms .com/downloads.php?do=file&id=415
I see that it's based on "the latest Verizon released VRBMF1 Jellybean 4.1.2 Base and is De-Odex" - does this mean it will still appear to be a Verizon branded phone? Any ideas?
Thanks again.
