No data - T-Mobile LG G2x

Did anyone else power up and couldn't get data? What did you do? Wifi works and I can't get calls but no data at all.
I love the phone so far. Yes, I have LED bleeding but I don't think it's something that's going to bug me though.

I feel like such a dork. No wonder no one else had this problem.Couldn't figure out why I couldn't get data. Tmo told me that it was my sim card. It was from the days of stonehenge. Yep, it was my original card from 2000. Once I swapped it out all was good.

I think I'm still using my SIM from my monochrome Sidekick, without problems, but there's probably a cutoff at some point for these.

[Q] Network Dropping

I just want to check in and see if any other Inspire owners are having this issue:
I have noticed that my phone occasionally drops the network connection and doesn't get it back right away. There are two different flavors of this issue that I have experienced:
1) I was walking my dogs today and the phone suddenly dropped it's connection to AT&T completely. After a few seconds, it reconnected and everything was fine. I was in an area with good coverage and the status bar showed no connection at all.
2) When home, I leave the Wifi on. Earlier today, when I tried to make a call, it simply wouldn't dial out. Then I tried to open a web page and nothing (after turning wifi off). I had to switch airplane mode on and back off to reset the connection. I also received several text messages at once, all of which had been sent hours before (as indicated by the time stamp on the message). It's almost like the phone has an issue swapping back and forth between the carrier connection and the wifi.
Is anyone else experiencing anything like this?
As an update, I noticed that when the wifi is on, there's a check mark under the H+ symbol (rather than the up/down arrows) and when I switch off Wifi, it doesn't go away. During this time, I have no cellular data. Switching airplane mode off and on doesn't seem to work. Sometimes it recovers on its own. Other times, I have to turn the wifi off and on several times.
This is annoying. It seems to be having issues doing the hand-off between Wifi and cellular data. This is really the only issue I have with the phone. Hope they roll out a fix soon.
I had the same problem. I thought it was because I had to add my own APN. (I could not switch my plan around because it was a work SIM). This caused SMS messages to not go out and an overall bad network experience on the phone. I have since returned the phone because I need a reliable network connection and the ability to send/receive SMS messages at all times. Once a fix is found I will be back. I liked the phone alot otherwise.
Are you by any chance using the SIM from another phone? I had the exact same issue yesterday and data did not work for me until I called AT&T and had them update IMEI number from Captivate to Inspire. Hope that helps.

Nope. I made it a point to have them activate it in the AT&T store with a new sim because I had read about people having issues when they transfer their SIM. I also had and iPhone 4 previously, so transferring wasn't really an option. I'm definitely on the right data plan, too.
I left the wifi off all night and it did it to me again today. The check mark shows up under the H and it loses all data connectivity. I'm not sure what is causing this, but I'd love to know if there's some kind of workaround. I have messed with a few options (like the data always on option) and haven't had any luck.

I was using a SIM from another phone. It is the SIM card from my Work phone and I can not change the plan. It does have unlimited text and internet I just cant change it to a 4G plan. I had added the APN that is floating around here and that worked except I was having the same problem as the OP.

Like I said, my issue was very much like yours and OP's and adding cutom APN made no difference until I called AT&T and had them update IMEI on my account. Presto, all problems went away instantly. I understand that it's not an option for you, sorry
have you tried creating a new apn? try creating one using these settings.

Just did this. Thought it might have resolved it at first, but it didn't. Basically, when I put the phone down for a while, it's like the data connection goes to sleep and doesn't wake up. When I turn the screen on, there's no mobile data. Sometimes, the dual arrows are visible under the "H", but only the up arrow is lit. Other times, the check mark (meaning no data) shows up under th "H" and stays there. Switching Airplane mode off and on will reset the connection.
I hate to say it, but the phone may have to go back. I love everything else about the phone, but this bug is too major to wait for an update or fix. What good is smartphone that doesn't get data reliably?
are you running the stock rom? i haven't been using that rom much so it may behave differently than the custom roms.
i don't think its a common bug. i would see if you can get a replacement phone.

Definitely stock rom. No rooting or anything. I didn't notice this on the first day I had the phone because it was on Wifi almost all the time. I turned wifi off to test it and the issue persists. I suppose I should try resetting the phone first, though I'm not looking forward to setting it back up again. After that, I'll take it into AT&T. I'd love to keep the phone. Can't believe no one else is having this issue.

yeah, resetting it up is a pain. sorry, and i hope you get it fixed.
Just to say it again. I had the exact same problem as the OP. Maybe we both had a flaky phone?
Okay, turns out there's an issue with the AT&T tower closest to my house. I found out from a rep at AT&T. I haven't left home much at all this weekend, so I had no standard for comparison. I just verified it by turning the wifi off on my iPad and using 3G data. It has the same issue.
Of course, I had already done a factory reset and gone to the AT&T device support center, but at least my phone is fine.
As a side note: I love that Android restores your apps now. I always thought WebOS was awesome for doing that and that was what frustrated me most about Android, with as often as I swap phones.
Wow... Wish this was my problem. I switched back to my Palm Pre+ and my data works fine.

G2x Data Issues (No 3G or 4G)

Hello i just picked up the G2X phone today and upon leaving the store the phone had begun to have data issues. Meaning it was not keeping its connection, which left me with no functionality to the internet.

No such issues or complaints on this. Were you on wifi in the store?
Sent from my LG-P999 using XDA Premium App
No, wifi wasn't enabled in the store. As a matter of fact, i actually tried to use the wifi when 4G begun having data issues and was unable to find any networks.
Mine has randomly disconnected from 4G as well, although the status bar still shows it connected. If I restart the phone it comes back on.
I think it may have something to do with toggling on wifi, but it has also happened after just sitting idle for an extended period, and wont come back on.

Well, I think LG should of did a lot more QC before they even though about dropping this phone on the shelves. There is also a lot of little stuff that this phone is just not doing that my optimus T did flawlessly.
I'd have to agree. I'd recommend having your sim card replaced to see if that helps.

Interesting ill tell you how i was able to get the phone. I was actually on flex pay the TM rep ported my number to a new line on our family line. Before that happened i was using a different number that wasnt attached to the sim card i am using now and 4G internet was working correctly on that sim card.But, Now that you have stated your issue. i think im going back to the tmobile store and see if they can get a new sim card for me.
So I'm not the only one with the network issue. seems like as soon as I disconnect from wifi I lose network connectivity. I still see my signal but can't access the internet at all. Totally locks up until I reboot. Which is proving to be a pain in the butt.
I'm going to t-mobile today to get a new sim card to see if that changes anything, mine is currently from Oct 28th 2008. The day the G1 was first released. Can't even read the numbers anymore. But to my knowledge the cards haven't changed. Guess I'll see if this fixes the issue.

That is the way it is designed. When you have WiFi on, it disables your Cellular data to save power. Hence why the 4G icon disappears.
When you disable WiFi, it has to reenable the Cellular Data. So it takes a sec.
Now if it NEVER comes back then there is a problem. But don't expect it to be instantaneous.

When I have wifi on, the 4g icon still comes on and off constantly. When wifi is off, 4g icon still blinks on then off constantly. Still don't have any data. New sim card didn't help either. I go through a battery in about 4 hours because its constantly connecting and disconnecting to the network.
LG sucks.
I'm pretty much convinced this is related to Wifi calling. Try disabling that (this will also help your battery life something serious - take a look at devices logs when wifi calling is enabled.)

When I upgraded my G1 to my G2x, they said they had to give me a new SIM card because the old one won't do 4G. According to the sales person I spoke with, you will need a new SIM card.
Can you keep your old number with a new sim card? My sim card is the same one from my first phone, nokia 3390
I'm having the same problem.. I used a new sim card and I still can't get any 3G or 4g for that matter.. Any ideas or is my phone defective??

i believe all the phones come with the setting already on GSM Only. YOU NEED TO CHANGE IT TO GSM-WCDMA AND YOU WILL GET YOUR 4G SERVICE TRUST ME IT WORKED FOR ME, SO GO INTO WIRELESS SETTINGS AND TAKE OFF THE GSM ONLY SETTING

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.
It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/
Sent from my LG-P999 using XDA App
Did you get yours at release? If so it may just be the first batch or something...
Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.
I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem
I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)
Sent from my LG-P999 using XDA App
P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.
So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

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 .

potential signal problem

Hey everyone, i'm a new coming from the OG razr and while i heard the radio on the s3 isn't as good as the razr i think my phone might have a problem. It seems to get stuck on 1x a lot and the only way to get back to 4g is to restart the phone. my phone is rooted but stock rom. Is this a common problem? Also under under APN LTE verizon internet is checked not EHRPD. Is this correct?

Yeah it's true, put simply. You can see if it's the sim. But like I said, if you try to get a replacement after your return period, then you'll just get a refurb. So be quick on the draw if the sim card doesn't fix it.

S3s are known to have a number of data issues. Call technical support and try their ideas. When you can rule everything else out, then you know it's your phone. Basically, if a new sim or a factory reset doesn't fix it, you need a new phone.

Alright, I sent them an email and will probably call them if it starts to get worse.

dont know how to use odin but the instructions seems easy enough. Just got off the phone with CS and they tell me its most likely the sim card and not the phone and to go to a store to replace it. Is it true that the sim card actually controls the signal?

I took my phone in the store yesterday and they told me flat out that I sim card won't do anything for your signal. I'm not discounting what you're saying, just telling you guys what they told me.
My signal is garbage at home AND at work. I use wifi at home to play with the phone but actual 3G signal is bad. I am lucky to get 2 bars but its generally 1 with speed tests of about 80kbps.
I don't have WIFI at work, and get no signal at all.
I still have a week to return the phone but I'd like to keep it if I can get a better signal.
I am still within my 14 day, maybe 5 days left

Are you new to VZW or have all of your phones had the same problem?
With the thought of you possibly leaving VZW, you would think the store would have tried a new sim card, if only to pacify you. Or they might have offered to switch out the device.

I have been with Verizon for years. My Droid X didn't have the best signal but it was much better than this.
One problem is, the store is located in a 4G area, it works great there but it doesn't where I live, nor where I work (which is a decent sized city)
It sounds like you have a bad phone. I'd be pushing for a new one before your worry-free period is up.
Okay, I reset my phone this morning and surprisingly, the signal is much better.
I went from 80-100kbps to about 500-600 kbps. Does that even make sense? The phone is only a week old
Now, perhaps I'm getting too hopeful here and the wind is blowing the right way today or something.
Yesterday I checked my signal with 'Open Signal' (I'd love to know of a good tower location app), and my signal was about 20-23%, right now its at 32-37%. I know that isn't a great jump but in the scheme of things, it is. I'm also at -97dBm, I think yesterday and the day before was over 100
I will note however that I'm still at 2 bars of 3G
I think its just chance , but I'll keep an eye on it.
Couple of weeks ago I also contacted VZW about bad signal/slow data speeds with my phone. They also told me a SIM would be the first fix to try. I had them send me one, for free 2nd day.
Before I swapped it out.. I rebooted my phone and put it in a certain spot and observed signal strength. In my house it ranges from -109 to -113. The data speeds, when the test would even finish, were abysmal. Ran 3 tests and in general they were about 500Kb/s down and anywhere from 0 to 300Kb/s Up. And that was on LTE!
Now without wiping my phone or anything I installed the new SIM and called VZW to activate as their website was bombing. Finally got the thing activated then put my phone back in the same exact spot to observe any changes. While signal strength did not get any better my data speeds increased a whole lot! In the same spot I was getting 5 Mb/s Down and 3 Mb/s Up on average.
Ive also noticed a decrease in LTE drops to 3G and 1X like I was getting before.
So while Ill say that it would seem to be impossible for a SIM to make your signal better, it just may help with your connection.
Thanks for that, I'm going to go up there in awhile and at least swap the card
Well this is my side of the story I had the Galaxy Nexus before sometimes in New York I am in spots where I dont have 4G what is weaird when I go into someones house which i've been many times I only get 3G and then when I go outside I get LTE anyways at the same spot I get 1-2 3G bars and my friend gets 3 bars on iPhone 4S but when doing speed test on both it seems about the same.
Also I am running CM10 and when I was on stock I could tell the signal was a little bit better , you guys think it would be worth a try to swap out sim card as well? how do I make them give me a swap for free?
