First of all, I'm stock and running faux kernel. I started experiencing this problem yesterday when I had no data and I was outside (Where I usually get 4g speeds). Now I either get 1x data speeds or none. Is there any solution for this problem like hard reseting or something

That sounds like either a Verizon problem, or sometimes your phone wants to revert to an evdo state if it can't get a 3g or 4g signal.
Download the phone info app, and open it and click device information, make sure it says lte/cdma/evdo and not evdo only.
Sometimes the setting won't stick, so in that case I would either flash a new rom or go back to stock with Odin, ota update, and reroot again.
If it says lte/cdma/evdo, then I think it has something to do with verizons end.

Actually I tried something else... I took my sim card out of my s3 and put it into a friends verizon s3 and the data didn't work on his phone but once I put his sim card onto my s3, I had 4g and many speeds I thought never existed. So what does that mean?

Pulling your SIM helped your phone to relock onto Verizon towers. It just essentially resetted the prl, glad you got it working fairly easily.

Not exactly, because my s3 for some reason got 4g and 3g when I inserted my friends SIM card onto mine but on his s3, his data was acting like mine because he had my SIM in his s3... so that draws me in one conclusion, my SIM is damaged

Ok so I got the Infuse today. Go ME! The screen is sooo much better than my captivate's, if that's possible.
So I take the SIM card out of my old Captivate that I got this time last year. I have the 2GB plan for it. But only now, my Infuse 4g has no data connection even after letting sit for a few minutes.
I did some looking around here at different APN settings and they didn't seem to do anything except cut off my Phone service. Some other people suggested my data plan might not be up to par. But I have a data plan for the Captivate that I activated when I got that phone. Are the phone's data plans really that different that I have to call AT&T to resolve it?
The phone is totally stock, no flashes done to it, hasn't had root attempted on it yet. Brand New out of the box.
You have to call att to have it switched from 3g to 4g I had the same problem they had me give them some numbers and put some numbers in my phone then everything worked.

Ah. Thanks then, that should be easy enough then. Too bad its today though, even the non US tech support is closed till tomorrow.
If u used the sim out of ur captivate u need a new sim because infuse is 4g and captivate is 3g(it makes a difference some over the phone tech doesn't know better). I had this problem

When I'm blocking someone its on purpose and I use call master. If there is a problem with connectivity I can reset the radio layer or reset the telephony service. This might be an idea just to have the ability reset the radios at different levels in order to clarify the problem

(put it back to gsm only and it started working even with data on, but when its on LTE with data on is when it starts screwing up) does that mean when its connecting to an lte tower its messing up? Is that my phone's issue or the towers? Is there anything I can flash to the phone to see if the problem goes away.. already flashed stock radio but didnt help

Sent from my SAMSUNG-SGH-I727 using xda premium
any fix??? it just started happening like four days ago and never had this issue before.
This is a known issue, at least in Canada with Rogers. It has nothing to do with what rom or Kernel you are using.
It appears that Rogers is having intermittent issues with the LTE network. It comes from the handoff between LTE and 4g when a voice call is received. After you hang up, you are supposed to go back to LTE automatically. But with this glitch sometimes the phone will get stuck and as a result you get no texts and calls going straight to voicemail.
You could try creating a new APN node for 3g/4g only and using that to see if it solves your problem while Rogers is actually becoming aware of the issue and fixing it.

The same thing happened on my non-rooted Verizon S3 after using Phone Info app. Verizon tech said my phone was defective. When I went into Best Buy, they started switching my phone to a new S3 and it still did it...found it was the sim card. After I got a new one, it's been working ever since.
I have posted the fix in about 4 other threads...you need to reprovision your device with the dialer code

Id say delete the phone info app or wait until it's updated to be compatible with jellybean. 3g is almost then same as lte anyways at least with my phone I almost always have a strong lte signal. The s4 chip in the gs3 was designed to be a power saver on lte compared to older chips

Ok, so if I delete the app is my phone still stuck in 3g mode somewhere in else in the phone then? I guess what I mean is does deleting app force the phone to run off the APN settings? And if this still doesn't work can I use the re-provision code ( *2767*3855#) that I saw earlier in the thread? Finally is there a way to simply check if my SIM card is screwed?
I just got my phone back from mobiletechvideos JTAG service. Since then, my phone struggles to hold WiFi and 3g. It very rarely pulls 4g. I have tried a factory reset. Also restored my IMEI backup just in case. I have an extra micro sim arriving today. I'm just wondering if I could be missing something simple or is my phone royally screwed?

I did take the phone apart and found that the WiFi connection was loose. I corrected that. I started the phone back up and held the Sim card down in the slot while booting and the phone miraculously got 41asu.....for about 5 minutes and now its holding at a steady 2asu. So, would there definitely be something wrong with the Sim card? Or could the Sim port be going as well? Is there a way to test the Sim connectivity in the phone settings?

The lower the asu the better, in contrast to a higher dbm is a better signal.
2 asu is a pretty strong signal, you should be around -80 dbm.
Edit; Nevermind I mixed it up, a higher asu is better. I still think it's radio related though, but changing your sim card is an easy potential fix.

What is your IEM Showing?
If its been erased, then ODIN to stock firmware probably won;t fix that,
but, have you check your mobile network setting to see if you are on the correct network?
If you are with Verizon it should be set to CDMA, not GSM.

Just for kicks, I would turn on airplane mode and let sit a second then turn it back off and see if it does any good. If not power off, pull battery, sim, sdcard let sit for 30 secs to a min with nothing installed. Then put sim, sd, and battery back in and restart. The 4g data is refreshed with the sim being pulled.
Good luck,
