Network Connection Issue - No 3g/4g

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.

Network error
Sent from my SGH-T989 using XDA App

Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

Can receive calls but not make them

I apologize in advance if this is a thread somewhere I couldn't find it.
I was recently using CM9 alpha3 on my E4GT, and last night suddenly I wasn't able to make calls. It says "we're sorry but we can't complete your call right now" or it just instantly hangs up. I thought it may have been an issue with the rom or modem, so I went back to Calkulin's GB EL29 ROM. Same issue, even after resetting PRL and profile multiple times with phone restarts. I can send and receive texts, and I can receive calls, but I can't make calls. Another thing to note is I use an Airrave in this house, I tried resetting that as well, and dialing *99 which is supposed to also refresh or reset it. None of these tactics have worked and I was wondering what else I could try. Thanks again in advance!

Maybe you might be hotlined from Sprint. Sounds silly but is you bill paid?
Sent from my SPH-D710 using xda premium

possibly Blacklisted
expanding on the previous post..
Did you get the phone direct from SPRINT. or via ebay or at a pub?
Bills paid?
are you the only registered owner of the handset?
people will sell you a phone, then after a little bit of time passes. they register the phone as LOST/STOLEN/DAMAGED the network Blacklists it and provides the fraudster with a shiny new handset.
you end up out of pocket without a working phone.
its an increasingly popular fraud technique I'm afraid.

Silly question but it needs to be asked, are you sure it wasn't something with the number you were calling? Did you try calling several number?

Airrave services are having issues. Power it off for a day.

The bill is current, I have called multiple numbers, both on the sprint network and others neither has worked. I have other family members in the household on the same plan using the airrave and they are able to make calls. I bought the phone directly from sprint brand new from the store with my 2 year contract.

Why don't you use sfhub's one-click EL29, get yourself back to simple stock rooted and see if it clears up the issue. It's always my fall back whenever something goes awry.

I did actually use that right before I flashed Calk's E4GT rom and I had no luck with it either Probably should've mentioned that.

Don't reflash Calkulin's ROM until you've been able to recover your voice calling services. Both CM9 and Calkulin's ROM are custom, so maybe that's where the problem is coming from. You need to get back as close to stock as possible then see if the problem persists.
Go back to EL29 (plain stock or stock-rooted), see if everything is working then you'll know if maybe it's something in the flashing process that is knocking out the voice calling.

I'm also having the exact same issue with my airave. If I unplug it I'm able to make calls without a problem. So as someone else posted I believe the airaves are having issues today. But I am on the stock FD26 ICS if anyone else is having the problem and thinks it has anything to do with the leak.

Yeah I unplugged the airave and I walked far outside to get a bar and was able to make a call. Didn't think it was the culprit because other family members can make calls with it, they have different phones though.
Thanks for the help guys

Having the same issue as well today. Tried powering down, chatted w sprint, still having issues. Don't think it has to do with build or rom as I have been on just about everything since I had mine.

Exact same issue here too. Started yesterday morning. Have not had a chance to test it out today. Sister's iPhone works fine with the airave. Seems only my phone is affected for some reason. Spirit said they would get back to me in 72 hours. Hope the issue is resolved soon. Using Grooveip to make calls in the meantime.

Four people in the house on my plan and no-one has mentioned any issues with the airave other than the spamming txt issue sometimes.

Update: mine just started working again. Last night I reset the box by pressing the reset button for 15 seconds, still having issues after it reset through this morning. Sometime in the last hour it has become fully functional again. Weird.

Not receiving calls

My wife and I are stock and we are having issues receiving calls. Is this a known issue with this phone?

If you are 100% stock, you may want to call tmo.
Have you done a hard reset? Does calling over wifi work?
Sent from my SGH-T989 using XDA

yeah we are 100% stock. It's hard to tell if we miss a call on or off of wifi unless they leave a voice message as some calls go straight to voicemail. I'll try a hard reset. My wife tried calling me six times and I didn't even get a missed call. Same thing when my mom called me.

Go to your local T-Mobile store and they should replace the phone or the sim card.
If the phone is the problem just hope you are under warranty, you should be.

what radio are you running?

It is interesting that in the last week there are at least three threads dealing with missed calls. Is there something going on in common? I have found that I was only missing certain calls from certain numbers. 100% reproducible. If I call my cell from my work phone AND the work # is stored in my contacts, then I do not get the call. It goes straight to voicemail. But if I remove the number, I get the call. Add the number back and I miss the call.

Well I havent rooted the phone yet - as if this issue continues, i dont want to void the warranty as I can try for a replacement. I am not sure once I root - can I do something to make it look clean and not void warranty!
If there is any suggestions - I will definitely try it out

No 4G/3G

Ugh! So where do I begin.. First of all I am running the MOAR most updated version in the OP. Have been for a while. Haven't been able to update PRL/Profile in I don't how long. So I like to here and there to make sure all is well. Anyway today I started messing with it and I used some secret code I found in the MOAR thread for hands free activation. Well, that went south since I am unable to update PRL/Profile. Then I called Sprint and she got the hands free activation off. I was still unable to update PRL/Profile after that. I went ahead and downloaded the latest MOAR and wiped EVERYTHING!! Then flashed the MOAR. I am not sure exactly when the 4G/3G problems started to happen. I am thinking before I flashed the ROM again. But anyway in a nutshell I I can not still update PRL/Profile. Gives me internal error and now I have no 4G/3G. Sprint wanted me to call them on another phone and I assume to deactivate my phone and reactivate it or something idk. I remember one time my sister had this issue and I was in the phone 5 minutes and it was back. IDK why I am having such a issue.

I had the same issue on my first flasb. Forcing hands-free activation fixed it

EDIT: Make sure you're connected to wifi when you do it.

Right. That did fix it although after I still was unable to update PRL/Profile. But right now I am having an issue with no 3G/4G. Sprint said it could be a hardware issue with my antenna which I find hard to believe. I am downloading another ROM now and see if that works any better. Not sure what else to do. I don't have 50$ and I am not trying to pay for it. I find it hard to believe that my antenna is just not working. Although I was on the phone with her for 50 minutes and it seemed like we tried everything I just don't want to give up.

Odin back to full stock... Usually clears up lots of issues. You can reroot and flash moar again.

Is odin back to stock difficult? I would think it would be easy since to root is fairly simple. I am going to keep downloading this ROM. Then go back to stock and see if that works.
EDIT: So on my second call to Sprint today this guy said I need Sprint Zone and I need to activate my phone. Having our phones rooted I did not have this app. Thankfully I seen it posted so I put it in my DB and installed it and it installed but the app was no where to be found. I even flashed the app pack and installed it same issue. Then I called Sprint two more times just to come to the conclusion that my phone antenna could be defected. Which would cost me 50$. Anyway, I thought it was something else I could do. Sitting here downloading a ROM on my phone and on my laptop going to thread to thread. Hangout convo to hangout convo I see the status of the download. Well what do you know Sprint Zone is updating. So I updated it and it opened. Said my phone was not activated. So I activated it, phone restarted and I have 4G LTE and I went to the browser and it works. Finally caught a break. Thanks guys!! @edfunkycold @CNexus

wifi calling keeps failing

So, running Wicked V4 since it came out. Zero issues has been fine. Now, after having flashed CM, Wifi calling keeps breaking. I reflashed V4 last night, wifi calling working fine. Set everything up, still working fine. Wake up this morning, working fine. Get home from work, does not work at all.
It says I am not connected to a wifi network, but I am connected too my home network. Any ideas?

Shut everything off and then Wi-Fi on then after connected Wi-Fi calling on. Make sure Wi-Fi call is prefered

Tried that. Same issue. Says I am not connected to wifi. Just makes no sense.
Does CM screw stuff up on this phone requiring a full restore to fix or is there a way to do a complete restore with the dialer? I know when I had the GS3 for verizon CM would absolutely screw stuff up if you flashed it. You could fix it by typing a reset code into the dialer. Didn't see one though for the Note 3.

yes, last night wiped system/data/cache/dalvik cache. Flashed rom, set up. Restored apps via mybackup pro, setup wanam module. Woke up this morning to wifi calling still working fine no issues.
Got home from work and wifi calling doesn't work. I reinstalled everything that way, because the backup I restored magically had wifi calling broken after wiping everything from a flash of CM.

There is a bug in Wanam that overwrites system/csc/feature.xml - causing WIFI calling to break.
Download the update to Wanam (2.6.1?)
Then go to file manager system/csc/feature.xml and you should see a feature.xml.bak - replace feature.xml with feature.xml.bak, then apply your Wanam mods.

I had the "wifi" problem this morning. The error that I would get was something like my wifi signal was unstable and was switching over to data mode. My fix was simple. I power cycled my router and modem and BAM my note 3 connected immidiatelty to my network. I hope this helps anyone that is having this issue.
