T-Mobile Samsung Galaxy S2 - Data/4G not working

Got the phone two days ago.
Upgraded to ICS via Odin.
Root + CWM via Odin.
Flashed DARKSIDE.EVOLUTION.3 v8.
Didn't work for me personally.
Wiped cache and flashed aokp_hercules_build-M5_0xD34D.zip
Liked the ROM but noticed that signal bars were there but no data/4G.
Have been roaming the internet for hours now trying to figure out what went wrong.
All I can make sense is that something went wrong with the "radio kernel" or something like that.
If anyone can help me sort this problem out I would be extremely grateful. This phone was expensive and data plans are expensive, so I want to utilize both to their full potential. Thanks

I ordered two phones, the other was for a family member and theirs is working fine, even with ICS update, so there is no data outage problems in my area. As it turns out it was a defect in the phone. I contacted t-mobile and we went through this hour long procedure which produced no results. In the end, they asked if I would like to return the device or get a replacement. I opted for a replacement and so will be shipping it out soon. Lets hope the new phone doesn't go all unpredictable on me

"No Sim Card" notification

Anybody know how to get rid of this "no Sim card" notification? Sprint's GS3 version doesn't use a SIM card.
But no matter what I do, I can't seem to get rid of it. Even tried flashing different ROMs, and restoring previous nandroids that I backed up before I started getting that notification. No dice. What's the deal?

94 views, and not one other person has dealt with this.

I just don't get it. I even backed up my internal sd card and did a factory data reset, and it still won't go away!!
All I know is that this happened right after I used the wipe cache/dalvik cache feature in Rom Tool Box pro (which I hadn't used before) because I was about to flash a new Rom. And after it booted up again, it just appeared and hasn't gone away.

I was just looking into doing that. I was hoping I didn't have to do that. But at this point, looks like it's the last thing to try.

There is an option under mobile connections in the cm10 builds where you choose where your connection data lies. There is a NV and SIM option. This may be the cause.

Thank you! I'm going to try that! I've just trying to figure this out on TW, so I'm going to give that a go.

Actually, that did nothing. I saw the setting. But it doesn't really do anything in terms of getting rid of that "no sim card" notification. Sigh.
I just can't understand why I'm getting that blasted notification for no sim card. I'm on Sprint for crying out loud!
Sent from my SPH-L710 using xda app-developers app

So I've been trying for the last 24+ hours or so to remove this "no sim card notification. And I just flashed a leaked TW JB rom, LIG. And this one doesn't show a constant "no sim" notification. But it does show it in the lock screen. Ha! Jeez, this is driving me nutz.

Another possibility is that you're flashing a rewritten T-mobile rom and they never figured out the sim card issue themselves. The earlier leaked TW JB rom was leaked from a sim using carrier. Try downloading the LIF one or a previous ICS version. That or just go straight CM10 if you don't have 4G in your area.

Sprint phones do have SIM cards iirc... they are just built in and internal and are not ment to be accessible... can you make any phone calls? Other then 911.

Ok, so I completely wiped my phone, unrooted, returned to stock, did the hands free activation code, and still, when i rebooted the phone, it still has the "no sim card" notification. I'm completely fresh out of ideas.
I even spent two hours on the phone with Sprint techs and deactivated and reactivated my phone. They gave me all kinds of codes and proceedures to troubleshoot the phone, and still, no avail.
This is hands down, the weirdest thing I've ever encountered on an Android CDMA device. Makes no sense what so ever. Im just going to have to live with that pesky "no sim card" notification with every rom I boot. At least until I switch to Tmo. I'm done with CDMA.
I only found one other guy with this same problem, I pm'd him, but hasn't responded yet. I hope no one else geta this problem. It's just been the biggest headache.
*The pic below is after I unrooted and returned to stock. And still, there you'll see that fabulous "no sim" notification that I can't clear out* (sigh, sadness)

The only one i was on was Freegs3, i think it's L8 based, when it happened. Used the clear cache/dalvik cache feature in Rom Toolbox Pro, and when it re-booted, that's when it appeared.

I'd be surprised if there is a way to get rid of it. You may just have to use a third party contact manager if you want to stick with this ROM.

If IMEI is intact, it's a T-Mobile issue. I was replying to say that I've had this issue before, once. I was going to call them to complain, but it was fixed in under 24 hours.

Yeah, either call support to confirm, or give it a day or two to see if it gets better.

Happens to me here and there. sometimes I lose internet conection for 30min to and 1hour. I already called tmobile and told them bout it and how it started happening after they activated lte -.- they said its weird that it shouldn't be happening what should actually be happening is the data speeds geting faster. All they did is reset my data conection and gave me $5 credit for 6months:banghead:

Well if it gets better soon that $5.isn't a bad deal!
Have you tried Odin flashing the Stock firmware? Wipe data to test clean? Try any other modems?
Sent from my SGH-T999 using xda premium

Iv tried flashing stock via odin and it didn't help :/ so I called and got a replacement so far it hasn't happen anymore the thing that sucks is that the replacement I received is defective the home button is not sticking out how its supose to so I called and place another order but they are out of stock I kinda got upset when I was told I would have to wait like bout a week or so to receive my replacement so I asked if later on the road the home button started giveing me problems was I allowed to exchange for a replacement I wss told yes so I cancelled it cuz I could live with my phone like that not really a big thing

Sometimes if you press the issue they will replace it with a comparable model. They certainly have the T999L in stock if you want to ask if that's a possibility. Dont expect it to work, but could be worth a shot...
Sent from my SGH-T999 using xda premium

I called T-Mobile but they just reset the lines well that's what they said.
And nothing still the same data drops, iam going to try odin flash and I would see if that helps
Sent from my SGH-T999 using xda premium

If the flash doesn't help, wait another day or two and call back if it doesnt improve. Tell them you'd like to have a help ticket escalated because their last attempts did not help. Just try to get them to put you in contact with a tech who has the ability to deal with things on a more specific level. Most likely you only got the first level of support. They don't have many permissions to deal with a lot of issues. A lot if them are told that account resets will fix everything it seems like!
Hopefully though, things will jusy improve as they work on towers and upgrades.

Quick question on selling a 4G device

I am selling my Rezound and Dna on eBay. Does the sim card usually go with the phone, and if so do I need to wipe anything on it? Thanks in advance, never sold a 4G device before.

No, keep your Sim cards or toss em.
No need to send to anyone, they will need their own.

No, keep it or trash it as Santod said.
Whenever a device is removed from Verizons system it flags the SIM card as unusable for 48 hours, sometimes burns it completely. So whoever buys your device needs to provide their own.

Thanks to both of you.
