USSD code issue - T-Mobile LG G2x

In the last few days my phone has been cutting in and out of 4g/2g. Areas where I normally get 4g, its shows 2g. A simple reboot fixes it. Also, I have not gone over my cap and I'm not even close... another thing I just noticed today. When I run the ussd codes to check minutes/balance/data/balance the phone app force closes and the signal breaks. A couple seconds later and service is back. This is a replacement phone that I received last week I didn't have these issues. Could this be a sim card error?

Sprint Coverage Issues

At the moment I am on my third nexus phone first two got returned due to battery and touch screen issues.
Now on this phone phone either gets low signal so all incoming calls go to voicemail or the phone goes into roaming. I tried working with Sprint all I get is runaround instead of fixing the issue with coverage.
Wanted to find out if anyone else had the same issue with service. Phone is running stock GB 2.3.7

I live in s.e. Texas I get crap signalsb but not that bad bit sure where you live but this phone has way better internet and phone signal than my heroc did. Can try some of the ## codes I think buried in these threads are a list of them even a code puts phone into test mode maybe that'll help IDK gl

It happens to me couple times too ... too bad my 30 days return expired.. Planning to go through warranty center now ... It's kind of annoying because it happens kind of randomly
I have this same issue. They swapped the sim card so I'm going to see if that fixes the problem.
Is it a phone or network problem? On my third phone

I just got my sim swapped, and it still happens.. It looks like phone because my phone has full signals while it happens. It usually happens after long charge

I believe it's a software issue. HTC issued a statement regarding the WiFi issue, that until you get the OTA fix, you need to turn WiFi off and on again to deal with the bug. I haven't had the issue with phone calls that you're having, but I have had the phone drop the mobile data connection completely, or sometimes get locked to EDGE. The Airplane off/on trick fixes it, so I suspect it's similar to the WiFi bug.
If you can put up with it for now, it'll surely be fixed with an update before too long.
Good. Just wondering because everything else on this.phone is good. Ty

Lost all
I had problems at first just losing data and then finally after much time spent trying things with Rogers I lost all connection. Unable to make calls, no data, no signal. Got new one sent and so far so good for 5 days now.
Never lost data on this one bit had the no calls yesterday. None today. Maybe it will be ok. Someone said it.may be fixed. Just don't want to have to return the phone again.

Is a fix on its way?
I had this happen to me two days ago. The status bar indicated that I had a good connection and I was able to send and receive emails and use the web browser, but I couldn't send/receive texts or phone calls. After a restart, I had two voicemails and a few text messages (from an irritated wife!). I had been trying to make calls and send texts when she was calling and sending texts, so I wasn't just missing notifications.
Any word on whether this I a software or hardware problem? I still have some time before my 30 days is up and I tempted to go back to an iPhone if there is no fix.
I hope HTC releases an OTA soon...
This sounds like a network problem to me. In high traffic areas where cellular towers are overloaded , ATT service literally stops working. My entire trip to NYC I had no working service in Manhattan for this reason, and every professional sporting event I've ever been too the same problem has occured.
The "bars" were always good, but no texts or calls could be placed or received.
This happened on my a777, solstice, HTC aria, and Infuse
Seems like a reasonable explanation, except it has never happened before and was fixed as soon as I restarted the phone.
This happens to me EVERY time I am in an area with no (or really poor) service for an extended period of time, one of my classes doesn't get service because of the location of the building.. I've already gotten a sim swap and had my device swapped, it still does the exact same thing, only way to reconnect is by restarting the phone or turning airplane mode on or off. Hopefully it's not a widespread hardware issue and just a software issue that HTC can fix. Only problem is that AT&T has a history of taking FOREVER to get out an update that a manufacturer releases.
Oh and this never happened on my Xperia X10, even in the same class where I lose service.

Verizon GS3 stuck on 3g

Second day owning this device and love it so far, but day two has been rough. I am stuck on 3g. All of a sudden today my lte switched and will not go back. Iv'e rebooted, toggled airplane mode and data. Even pulled the sim. I live in a strong 4g area so that is not the problem. My buddy has a nexus and his is fine. I also have had great reception in areas I have always had problems, so not a reception issue. I called verizon and was told it is a know issue that is normally solved with a reboot. She said an update was scheduled for early September to fix the issue. The point of this thread is to find out if anyone else has had this problem, or found a solution.
Edit: After countless toggling I got it back to 4g, but it won't connect to the network. So my thought is that the sim card is trashed. Going to get a new sim card first thing in the morning.

Unfortunately I am also finding myself stuck in 3g. I have pulled the battery, installed a new ROM. Still working on it, not thrilled. Prior to 4g disappearing, it showed 4g, however I was unable to connect over it. I hope this isn't a hardware issue.

Did this work?
Just FYI, I have the SCH-i535 and am noticing similar behavior. I had a Samsung Droid Charge before the SGS3, and it stayed locked to 4G LTE in the same exact areas of my home. If my Charge did happen to drop 4G, it would always come back. But not with my SCH-i535. Once 4G drops it stays on 3G until I reboot the phone. So far, this is my only complaint about this phone.
It is very random for me. Im certain its a **** sim card. Right now its fine, but at any time it may get stuck on 3g. Also while at work the first couple of days it would hold a decent 3g signal, now its primarily on 1x. Once i replace the sim card I am hopeful for it to be fine.

I thought Verizon said that this was a known issue? I'm just curious as to why you would disagree. But if a new SIM does happen to fix the problem, please let us know.
Just a heads up! I have the same issue, but I can't get 4g back at all, which I thought stemmed from flashing CM9, but this thread is making me wonder now! I spent an hour on the phone with Verizon technical support and they said you will get a popup if the sim is the issue. They told me its the phone and they are sending me a new one. FYI you can try this code. *2767*3855# in the dialer to factory reset the phone ( can do the same in recovery ofcourse), but you HAVE to be running STOCK UNROOTED! Some people have had luck with this "resetting" the radio I guess. If this doesnt work, might as well call them and get a new phone coming. TRUST ME, I believe I did everything I could think of before calling them, except taking the phone apart and pulling a new radio out of my ass!! Lol
I'd just return the phone and get a new one if possible.
They did tell me it was known issue. Its just weird how random it is. I am hopeful it is either the sim card of a software issue. I hope it is not a hardware issue. I would rather not have my phone replaced as I just put a new screen protector on. Also to those getting a replacement, is it brand new or a certified like new device?

I did read in another forum that the replacement phones are coming out with a baseband update. I'm guessing that we will probably need to exchange our phones...or be patient for the OTA. Hopefully it won't be too much longer. Incidentally, I just did a factory reset and 4G now appears to be working. Time will tell...

I also flashed CM9, and I am fairly certain this was the cause of my problems. Nothing I did would make 4G work again.
Other 4G VZW devices seemed to work fine at the same time(I have an ipad3 for work, POS).
I didn't mess with it for a couple of hours while running errands, then all of the sudden it was working again. Been fine ever since as far as I can tell. It would be nice to know what exactly is causing this, but for now I'd caution against messing with cm9 .

Gs5 Activation Issue?

Hey guys,
I've had my gs5 since launch and initial Best Buy told me they were having issues getting the phones to activate and that it would take a bit... So I switched the default LTE/CDMA antenna to automatic mode and eventually it acquired data and LTE/3g works, however it keeps warning me about how activation isn't complete and when I let it go through the process it just ends up failing and retrying 5 times. I need to force close it to make it go away but If I restart it comes back.
TLDR: phone has data/service but still tells me to activate in notification tray.
Anyone else have this issue or know how to fix it? Much appreciated.

I've been having that issue as well. Do you live near a spark network area?
Where I live the LTE doesnt have csfb and I think that had part of the reason why it wouldnt fully activate. But I live near a spark network so i drove up into Ft. Worth and restarted my phone in LTE/cdma mode and went thru the activation process yet again. And this time it worked and hasn't come back since then.
I had a similar issue
I called sprint many times and went to multiple sprint stores
I finally got it activated though phone call
If the first rep can't activate it
Hang up and call again

Im having same issue here. Have you resolved your issue or just got used to it?
You're probably missing /carrier folder files. I'm not sure if Alpineman has them posted for the S5 in his HFA loop fix thread.

sm n915w8 dropping service issue

I recently upgraded into the note edge and I'm experiencing consistent service loss. Seems like anytime I use anything network related ( cell network ) after a very short period of time it drops signal and take 5 mins or so to reconnect.
It's running 4.4 android and there are no official updates available to me
I'm on the sasktel network. This is very frustrating as I really do love the device.
I don't believe it's a hardware issue I strongly believe it's software related.
I've googled and have found that the Sprint Edge was giving some people grief but I have seen few to no solutions (and the ones I've tried have done me no good)
Please help!
Ive got the sprint 915p and mine does the same thing. Very annoying. Inly way to stay connected 100% of the time is to stay on 3g which sux. It is a known issue from what i have seen. Some phones are said to work themselves out of it. Inwiped my sim card points down with alcohol and forced my phone to reprovision and do a hands free activation. Seems to have actually helped some.
Sent from my SM-N915P using XDA Free mobile app
I also experienced the same thing and I thought I am the only one. Mine is a Bell Note Edge and using it under Telus network. Since acquiring this one 2 weeks ago, it has been a constant pain. There are times when my network signal would drop from 5 bars to no service and lasts for about 2-5mins for every 10-15mins of each hour. I had replaced my old sim card and purchased a new one a few days after getting the Note Edge. There are times that restarting the phone would fix the issue for about a few mins then it would go back to no signal. There are times when my LTE would just hang for a good minute or so. No problems with wifi connection and data up/down is consistent.
I also believe that this is software related. I had the somewhat of a similar experience with my LG G2 but this was in regards to the Wifi d/c issue. I had to wait 2 months for a dev to look into the issue and when he did, i flashed the modded kernel and wifi was better after that. I also contacted Samsung Mobile and the customer rep mentioned that they are not aware of any issue, which meant he didnt know jack at all. Hopefully somebody figures this out. I had to revert to my Note II as my daily driver.
Ya i wish there was someone out there that knew what exactly the problem was and could fix it. Its annoying when someone on here says its a known issue and clearly there are people having problems and complaining about it then the service representative says they dont know anything about a known issue.

I had the same problem with sprint. Went there and found out that I had a bad phone. They ordered a replacement and swapped it out. No issues after that.

Ya im gunna do the same thing its just a matter of having time. They want to look at your phone and "replicate the problem" before they replace it. I have already sat there for an hour to tell me about certain towers being down. I guess it was working ok for them when they looked at it. Its not all the time for me. Its that every once and a while when i got time to kill and i dont have wifi that it decides to act up that pisses me off

I get that too. There are days and hours where my phone cell network signal works flawlessly. There are days when I could barely get a signal.
Ya its random with me too. After wiping all the pads on the sim with alcohol and doing a hands free activation ot seems to be doing a lot better though

On sprint, since i updated to LP, this hasnt been nearly as much of a problem. .. 1 dropped call in a week, in a busy theme park, in a tunnel....
