Missing incoming calls, poor data speeds after flash...help? - T-Mobile Samsung Galaxy S II SGH-T989

DISREGARD:
I dirty flashed a different kernel and it fixed it.
Greetings. Quick question for anyone who is listening. I could not find an answer that suited me on this.
I recently flashed the G wizz jelly bean 4.1.2 rom and everything seems acceptable except for the fact that when it switches from 3G to 4G (which is quite often) my data rates are horrible. In fact, the mobile data speed is very slow all in all, even though it says 4g/3g. Not just that it's visually switching. I have tried switching between GSM WCDMA auto and just WCDMA and it does not make a difference. I am in Chicago and I've always had stellar 4G service. I should also mention that I have wpied and reflashed this rom a few times just to make sure that's not it. Several different downloads of the same ROM too.
Also, I am missing incoming calls as they are going straight to voicemail from time to time. I've never flashed a radio before (this uses the latest radio UVMC6) I was wondering if perhaps that's what I should do?
Any links for radios, flashing instructions, and others experiences would be greatly appreciated (and would save me more digging). Thanks for any help on this. Have a great day all!!!!

(SOLVED) All users of CM6.XX and Ultimate Droid (AOSP) questions

I seem to have signal issues on both ROM's. I'll give you guys a little background information.
I've used Fresh and Myn ROM's and always get perfect 3G coverage in my house and around town. Everytime I flash an AOSP rom I can't seem to connect to anything but 1X (if I'm lucky). When I was using the 2 previously mentioned Sense ROM's I'd have no issues with data. For the record I don't do a restore of my system data or apps when I flash because I prefer to download everything again to prevent FC's and other issues.
I've done a nandroid restore and updated PRL and Profile in a Sense ROM (2X) and then restored my AOSP ROM (ultimate droid) and that doesn't fix signal issues. My girlfriend has an Evo and she gets perfect signal on 3G (4G as well but she has it off) so it's not network related.
I downloaded the latest radio and pri from the development thread and flashed them in recovery. That didn't do anything at all and may have been a waste of time.
I then did these steps:
Dialed *#*#463+#*#*
Clicked on Phone Info
Turned off Radio (waited 1 min)
Turned radio back on
Ran ping test (failed because of no data signal). I can make/receive calls but nothing data related.
Is anyone having this issue? This has prevented me from fully enjoying AOSP ROM's and I don't know what the issue is. I'm using the latest PRL but could it be that my radio is broken? I would ready appreciate any help.
*** Update ***
I'm typing this thread on my phone and it's displaying 3G in full bars and then jumps to 1X full bars. It's kind of random but never steady. If anyone can please help me with this I'd appreciate it.
By the way I have an Airrave. Could that be the cause of my problems?

Same. i have this issue. although i dont get 1X. but i do however get spiking signal.
from what ive learned, the bars arent ur reception but how good ur connection is to the....satelites? aslong as u have 3G showing ur phone/internet SHOULD be working. although i would rather like to see all full bars where i normally would
i'm in a pretty high 4g signal area, but i love ultimate droid. i too have loopy 3g using cm6 or ultimate droid, would gladly give up my 4g to use either of these roms, but the 3g performance is way slower than on a sense rom. it's not just the bars, 3g on aosp is almost unusable, on sense roms, it works nicely
I solved my issue. The root of the problem is the Airave and how it connects with AOSP ROM's.
When I flash a Sense based ROM I don't have an issue with 3G and signal. I'm in a perfect 3G area by the way.
As soon as I disconnected the Airave last night my 3G signal came back with a vengeance. It hasn't left and is steady. I plugged in the Airave again and I saw my signal disappear and never come back. I could make/receive calls but no data access. I have the latest version of the Airave. Could someone (DEV) of an AOSP ROM investigate this issue. I knew it wasn't my phone because it would only happen in AOSP ROM's.

[Q] Bell Canada i747m losing connection

hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.
Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test
I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread

[Q] weak coverage killing my battery Help?

I direct a summer camp in the summer and now that I've moved out to my summer location I have absolutely the worst data coverage at my camp. All throughout my campground my phone data switches from 4g to edge to no data depending on where I'm literally standing. I think that has been plummeting my battery life so I'm trying to find some best solutions. I'm currently running Intergalactic Rom which has giving me great battery life before I moved out here to camp.
1. Should I consider another rom such as a asop/aokp or does it matter?
2. I already tried locking my band selection to just edge but I can't receive phone calls when I do that. Is that a matter of having the right APN's? Right now my APN only shows the ATT Phone settings?
3. Does having the right combination of kernel settings, modems, etc.. make a difference too?
I would appreciate any help or feedback
Thanks

Turn off your data and see if that makes a difference. There are several apps out there that will let you switch it on off through a widget. I think one was something like aon on off, just a toggle.

will this affect whether i receive text messages or not?
No. Phone calls and texts will not be affected. MMS require data, though.
My 2g speed or edge is pretty sufficient. But I tested it out and I was able to place phone calls but not receive them. Is that a matter of configuring the right apn's and if i do stay on edge does that affect test messaging or mms?
Thanks again

help with data and voice problems

I rooted a T989. Flashed CyanogenMod 10.1. The phone call audio is very choppy. But people can hear me just fine. The data is also weird, its constantly rotating between 3g, H*, and DC. Sometimes changing every few seconds. On the stock ROM it was 4g all the time.
I've tried different kernels and radios. Im gonna try other roms now.
Can someone give me some advice?
For the call audio I suggest you to flash the new Jelly Bean radio: http://forum.xda-developers.com/showthread.php?t=2226835
Also the data is completely normal to do that. Stock ROM couldn't display what other data it's using at the current moment because it only has one image to display (which happens to be 4G
Hope this helped
I talked to a TMO support person a while back, and it was explained to me that TMO no longer has 3G. They only have 4G (which isn't a true 4G LTE network but rather a "sped-up" 3G network) and EDGE (2G). This is probably why we no longer see 3G on the stock TW ROM's. Also, many of the custom ROM's (other than a modified TW ROM) have versions that are used on AT&T and Verizon which still use 3G.
As far as the choppy voice, I'd try flashing the appropriate radio like the other person suggested.
Hope this sheds some light.

[Q] problem with 3G/4G when leaving WiFi

I just flashed CM10.2.0 from 10.1.3. I performed a wipe of data and cache so I'd consider is a clean flash. Since doing this, the phone will usually not switch to 3G/4G over the air when I leave WiFi. If I reboot the phone, it immediately acquires 3G/4G. This was never an issue with the previous ROM.
I see a lot of posts about these kinds of issues with the current nightlies but can anyone offer suggestions for a fix for the CM10.2.0?
I'm hoping that I just have the wrong radios flashed for 10.2.0/4.3.1 - I'm on FK01/FK02 and on Verizon so CDMA...

wow, would have expected to at least get some replies on this given this is a topic that is going hot and heavy regarding CM's latest nightlies.
Bottom line, I did a clean flash and the phone now has a terrible time doing any sort of handoff to cellular data from WiFi. Sometimes I'll see a 3G or 4G indicator and still not get any data, sometimes I don't get any sort of 3g/4G indicator and just see signal bars.
I've even had the phone refuse to make a call - it performs everything like it is making the call but nothing, just silence. I've never had any of these issues before so I'm going to have to assume something in CM10.2 is the culprit.
Going back to 10.1.3 I guess even though I do like some of the features of 10.2.
