[Q] Data going in and out - T-Mobile Samsung Galaxy S 4

So i work in a warehouse. My cinnection keeps going in and out, like my phone service. I am connected tobthe wifi which is always strong so that never fails. But sometimes my mobile data goes out and i cant send texts meanwhile i can search the web. Theres times it goes out for a while and i have to restart my phone. Never had such a problem with my s2 in this place. But then again my s2 was rooted and this s4 isnt. So what can possibly be the problem?

Its a network issue.
Do u have LTE there ?
My data goes time to time and its a period between switching LTE to 4g and 4g to LTE (best guess) .
Sometimes msg send error also pops up.

[LTE] Grey data connectivity

Is it me or do I seem to always have an issue with data and my phone. There are many times when I go to pick it up to use and the data, either 3G or 4G, is greyed out.
I've noticed it even if I switch my phone to CDMA only.
Any suggestions on how to fix it other than the obvious reboot or airplane mode?
Unfortunately, this might just be reception issues in your area. I have no LTE problems where I live.
That's what I'm thinking. The phone may just not know what mode to chose cause I'm in between the two.
I have to bump this thread. I'm sick of this. I can hardly ever send MMS messages when I'm on WiFi.
I'm not in a 4G area, that I know. I was successful in updating my PRL which I thought fixed my issue, but didn't.
It's not like I have no signal, 1 bar, -90dBm in my house. Even switching the phone to 3G only doesn't fix this. Rebooting is my only option, as turning on airplane mode doesn't help.
Does anyone else have issues connecting to data? I'm tempted to root, just to flash a new(er) radio, but I don't feel like restoring my phone.
Have you tried updating to the new radio?

Whoops! That's what I get for opening up threads in multiple tabs. I replied to the wrong thread.
Haven't tried a new radio, still would have to root it.
As for the wifi sleep policy, it's set to always. I dunno...

Yeah, that was my bad. I had multiple tabs open with different threads and posted in the wrong one.
I live in a spotty 4g area so its constantly switching from 3g to 4g and before it locks onto one signal it always does the stupid grey bar deal and sometimes it won't lock on at all even though I'm in a strong (3g) area. Restarting the phone works sometimes. All I know is that it better be fixed soon or this phone will be going back.

Yup, this is the issue I have. I can have strong 3G signal (all bars grey) but it just won't connect. Airplane mode sometimes fixes it, but I usually have to reboot the damn thing.

Except the issue is... the data won't connect after I disable wifi lol. Hence why it won't even send with wifi on...

We have 4G here in town, but I live on the outer city limits. When I get closer to town I get 4G.
I know where I live sometimes I need to reboot my phone for it to change successfully from 3g to 4g... Another thing people suggest is toggling airplane mode on and off to make it pick up signal

I thought about taking it in and replacing it.... I don't have any reception issues, just this issue with the phone not wanting to get on data about 50% of the time.

You are having issues connecting to EVDO so your phone is in 1xRTT mode.
Try update profile.

It does that scanning of different channels either because of authentication failure or because it can't find an evdo signal. It is just scanning the different frequencies defined in the PRL.

Getting really slow data...

For some reason lately I've been getting only Edge in my area when normally I get extremely solid H+. I don't know if my phone is acting up (completely stock on 4.1.2) or if AT&T may be upgrading their network in my area, possibly adding LTE. Any ideas why?

Sometimes when I get this, I just airplane mode cycle. Sometimes im stuck on far away towers.

Sent from my SAMSUNG-SGH-I317 using xda premium
Let us know if it doesnt work. It happens. If youre getting it a lot. Thats not usual. Or if it happens in your house fron 4g down to edge. It could be an issue with your tower. Or location. Maybe the tower is overloaded and they kick you to another?
This has happened to me once on this phone. And it was on either stock rom or blackout. Cant remember
Sent from GN2 using XDA app
Well where I work I get full signal. Averaging 10 Mbps down on H+. But recently I've only been getting Edge. It could very well be what you said about too many users on one tower. I'll try tomorrow and let you know.

A few months ago when I had my Galaxy S3 I got this problem out of nowhere. I never found a solution even tho I tried going back to stock and several other "fixes". Ended up having to send the phone back and getting another one. Idk if the antenna went bad or what but even on Edge it was unresonble slow
Well I couldn't hold myself back the other night and I flashed Jedi X. Haha. Having no data issues now.

I'm forced to use HSPDA due to the LTE network being overloaded here in SoCal.
Funny thing is, with LTE on, I avg about 3down/10up....with HSPDA, I get roughly 6down/1up. Quite frankly, I care more about download than upload anyway so it's actually better for me

[Q] force 3g on GS3

I recently rooted my GS3 and i have been trying to figure out how to force 3g service on it any help? since i can only pick up 4g in certain areas im tired of the EDGE 2G.
Im pretty sure you cant, seeing as hspa+ is still technically 3G or WCDMA. So I think your stuck with Edge for now... Until T-Mobile does more service upgrades in your area... Don't worry, I get crappy service wherever I go, and I have the worst service here at home... Should have went with Sprint...

You could try, but AT&T uses the same thing "HSPA+" which is really 3G, but they still call it 4G, and that's what would show up on your status bar (it would still say 4G), so I don't know if that'll work... You can give it a try though. I'm actually going try it our right now, and see how it works. I'll keep you posted. :good:
Have that issue too and don't count on them upgrading anything anytime soon. Just wait till your contract is up and make that switch

I guess you can take the 4G plan off your phone and be throttled down to 3G speed... That's it.

HELP, no connection after flight from NC to TX

Hey all,
I could really use some advice. I live in North Carolina, my phone has worked just fine for over a year. Monday I went on a business trip to Dallas Texas and my phone won't connect to Voice or Data services at all. What can I do?
I tried turning airplane mode on and off, removing the battery, chatted with Sprint online, called the Support number. Sprint is NO help at all. They didn't outright tell me that my phone was broken, but practically did. I guess it just magically broke on the plane to Dallas??
Even in areas with good coverage, like my bars show good connection, I can't connect. I can hook to wifi just fine, but that is it. Sprint support told me that they can't even see where my phone has connected at all since I arrived in Texas.
Should I try flashing one of those PRLs from another thread? I'm not sure what to do. I assume that as is my phone will start working again when I get back to North Carolina though. I tried reflashing a "stock" rom and some of those "#" number calls, but none of them work since my phone isn't connected to any towers. Help!
Did u by chance try ##72786#? That's the hands free activation. Will turn ur phone off and should boot back up after a few seconds

That is what is so strange, I can dial that number, even from a stock rom, and my phone doesn't do anything, it just sits on "dialing" then makes the hang up noise after 15 or so seconds.
That's definitely weird! I'm from this area so I know it's not the water...lol. Have u taken to an actual sprint store?

Not yet, since I'm here on business I don't have much time to do that, but honestly I don't think they would be able to do much more than the support person over the phone did. I'd have to unroot it and all of that before bringing it in, the folks in the store would try those ## type calls, wipe my phone and reset it, then probably tell me my phone is broken and try to sell me another phone, especially since I am eligible for an upgrade.
I don't want to actually buy a new phone until I get back to NC since I still think my phone will start working once I am back there, which would be just as confusing.
This is the same phone I brought here to Texas last October and it worked fine, so I don't know what exactly the issue could be.

If you are still having this issue I would suggest you try an app called Network Signal Refresher. It basicly updates your prl and profile by connecting you to the nearest tower

Thanks, I gave this a try, but it doesn't look like it worked. Part of the issueI think even for PRL updates is that my phone won't connect to the towers. Like with a Stock Rom in the Sprint Zone you can get to that section where you can do a Profile update and all of that, it always fails with a connection error. I gave that error message to Sprint support but they couldn't do anything with it. I will keep trying it though now and then.

Is there a good updated guide for doing that? I did that on my EVO 4G, but never on the S3. I haven't looked yet but I will check into it this evening for sure.
They could be working on the towers in the area. When they did in my area, it showed I had bars but could not text or call. I would try flashing the 2 PRL, as it helped me get my phone working until they fixed it or in your case until you get Home. I can upload it if you need it.
