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 have tried a few, no luck. If you can give me a link of any that you think might work, that would be great

This is a shot in the dark but try going into your settings --> more... --> mobile networks--> and check "use packet data."

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

[Q] Canada Virgin Mobile S2, T Mobile 4G not working.

antenna boosters, do they work?

I've seen these things all over the place, some crazy designed hexagon sticker you stick on the back of your phone or battery that's supposed to boost signal.. do these things work? if these don't work is there anything that DOES? the s3 has the worst reception of any phone I've ever used.. everyone around me will have 5 bars, ill have 0 and were all on the same AT&T network, cept I got this godawful phone.. anyone know of a legit antenna booster? if it goes under my case no one will see it anyways
'Thanks' to any useful replies!

Could be a bad phone... Take it to your local ATT store and compare signals with their display model?
Sent from my SAMSUNG-SGH-I747 using xda premium

I have the i9300 not the att variant so there's no way to compare. but otherwise yeah I get 0-1 bar where everyone else with att gets 4-5.. I'm hoping its just the modem, and it'll get some nice upgrade in the future, but till then, looking external help
Sent from my GT-I9300 using xda app-developers app

Change your modem I used to get 1 bar to none on att now I get 3 to 4

I don't know if this will help but it appears to have worked for me. I can't find the original post with this suggestion so I don't know who to give credit to. Pull SIM card and battery. Put them back in and see what happens. It's improved my data tremendously. Hope it works for you. I'm on Verizon in case that matters.
Currently not being productive.

To answer your question -
No, they're a gimmick. If they worked, the manufactures would put them in there themselves.

It's been proven they do absolutely nothing

I had it on my old phone, galaxy s2, but it didn't work out. I didn't notice any difference.

Faulty phone for sure because the GS3 has like the best reception I have ever had and I have owned them all in the past two years, literally. Lol

Those things are still around?! Hollyyy....

SGS3 has fantastic reception. I have had so any different phones and this one has great signal strength.

Wow they really are a gimmick? I was not planning on getting one or anything but all this time I really thought they worked.

I have sprint and the reception is bad an air rave works well at home and a good repeater for distance check into the linkys E4200 v-2

[App ] to set WiFi to 2.4ghz, 5ghz or auto.

Note this was removed in lh1 and newer firmwares. Even worse is that I had mine set to 2.4ghz only and that Is what was still set after flashing to lh1 which means without thus app I could never have gotten 5ghz to work.

Thanks for this gonna make a backup and try it out
Edit: I don't know if I switch it over to 5 ghz it doesn't connect to anything at all. The wifi on this phone totally blows that's about my only gripe I just use the mobile network cause I know out won't drop!
Question: is there any possible way to actually just increase the power of the wifi? Or does that need some kind of patch or something? It would be nice to use wifi when not sitting directly in front of the router

Yours maybe flawed, my first s3 had trouble connecting to wifi, swapped it for another and no more trouble. I can be outside at my truck in the street and connect to my wifi in the house on the second floor

Shi**y beans whatever I guess I'm not gonna bother grabbing a new one I'll just wait for the s4 to come out next year

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.

I think is towers issue I had that in mind too, imei issue not at the moment just data drops and it stays on Edge for long until I put airplane mode for a moment and switch it back that's when I get H+ back

Yeah, either call support to confirm, or give it a day or two to see if it gets better.
Sent from my SGH-T999 using xda premium

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:
Sent from my SGH-T999 using xda premium

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
Sent from my SGH-T999 using xda premium

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.

Issues with wifi calling

Hi there
Recently I've been having a lot of issues with wifi calling. I haven't been able to receive any calls directly go somewhere voicemail and when I try to call somebody it says the call cannot be made at the moment
This really sucks because I got really bad cell phone reception in my house I was really thinking of using this as my main way of getting calls in my house
Is there any way to fix it or maybe troubleshoot it in anyway
By the way I'm running tweaked rom on my device

Has it always been like this (both in general and on the rom)? If not, any recent changes/tweaks/flashes/updates/installs that coincide with when you notice the decreased wifi calling ability?

Hmmm I think back now the issues started right after I rooted the device

Meaning they started on stock after all you did was root it? Interesting... I use it pretty often and haven't noticed any big difference between pre- and post- rooted. Maybe flash back to stock, test it out, and if all is well try again? That's what I would do anyway.

Most likely you are having these issues only when the phone has weak/poor wifi signal, can you confirm ?
