Constant network issues

I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.

Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...

I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.

Go complain here in LG forum. This is software issue.

have full bars but cant download anything. just sits at waiting for data connection.

We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)

I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.

Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.

4G lit up but no internet?

So inside my apartment I can make calls, but no internet. There's definitely some static and the person on a land line on the other end said every now and then the call wasn't clear. Literally outside my apartment I get 25Mbps 4G LTE speeds. Weird. I guess my apartment is super insulated? LOL no, it's California the walls are paper thin. What gives?
My wife's iPhone on AT&T works fine inside apparently. My EVO on Sprint works really well.
I don't know if there's any special setting or number to dial to acquire different radio towers...I don't know. But here's the most troubling of all. Why does my 4G (and sometimes 4G LTE) icon light up when I don't have internet?
It tries to connect and all but it's spotty and just fails. I literally can't use internet inside my apartment unless it's on WiFi of course...Yet my wife's iPhone on AT&T can and so can my EVO on Sprint.
I will be testing all around my neighborhood and the San Francisco area...But I keep on Sprint for not having LTE...But if I can't even use the damn phone on AT&T consistently I guess slower speed is better than no speed.
Anyone else with this issue? I'm curious since it's a new phone, new radio, etc. Is it known to have issues indoors?

this sounds similar to some of the problems others are pointing out in all those threads complaining about wi-fi. various fixes being offered. also at least one person had said htc is aware of the problem and claiming there will be a fix by the end of may. you may want to check the other threads.

Mobile data on in settings??

Yes it's on. It's just really bad inside my apartment and even on my porch (bad as in doesn't work and I have to use WiFi)...I thought maybe some sort of dead zone but again my wife gets signal with her iPhone. I hope it is something that gets fixed. If I can get this amazing 4G in my apt as well as down the block, I'll be a very happy camper.
If I can't use my phone in my apt ill be uh well I might be going back to sprint

call att and see whats up. Something isnt right.
I was with sprint, good thing i left. I have used more data in 2-3 days than i did with sprint in a month. Lol

Yea I would call AT&T. I think your phone may have a bad 4G chip. I had to send a phone back for every 4G issue in the book.
I just wish AT&T LTE was 25+mbs were I live.

I'm on 4G now inside. I didn't move the phone at all. It was on WiFi and after turning it off on then off a few times the 4G picked up. I see it now as HSPA+ and sometimes it bounces to LTE. But it seems to be working...at least long enough to post this message which is an improvement...

Walked around ny apt. Into the room I had no signal in before for sure... Seems ok. Bars dropped to one but now back in bed I have 3.
Also tested GPS directions today for fun and every few blocks it would lose GPS signal.
Never had such issues on Sprint and I'm not in the boonies...I'm in silicon valley of all places lol.
I don't know...how can you test for bad 4G chip? How can you test signal strength and what do I tell AT&T and what can they do for me? Or will they just say I'm unfortunately in a bad area?
Sent from my HTC One X using XDA

just a comment. i have not had your problem, but i've been following these threads wondering if the problem will eventually turn up for me. i've placed the widgets for mobile and wifi on one of my screens so i can access these easily. turning on mobile while wifi is on does not appear to overrride wifi, but turning wifi on while mobile is on appears to override mobile, as the 3g/h signal for at&t disappears. i'm doing this from home, so i don't know if it works the same way upon leaving home, but maybe... i should also add that i'm on an int'l one x using at&t prepaid.

Played with it some more. Here's how it works. When on WiFi it uses WiFi like it should and doesn't use 4G/mobile network.
The icon for 4G is lit. However, I looked under settings this time more carefully. It says disconnected underneath. If I turn off WiFi it attempts to connect to mobile network but fails. Endless loop.
I turned off everything. Turned on airplane mode. Turned off airplane mode (black box notification pops up with "preparing SIM card" and goes away). The mobile network connects now.
Right now my signal icon seems to switch back and forth from no bars with an X to 2 with 4G and LTE lit. I can't post this message when there are zero bars, so the icon I guess is now accurate. I'm not moving, I don't know why reception would be bad or off/on....can any other electronics cause well known interference?
But at least I could connect. I'm not sure if it was luck or if turning on airplane mode made it easier to reset itself.
Sent from my HTC One X using XDA

I know my speekers at home seem to cause some interference, but the phone win's so then all you hear is a crap load of buzzing.
How I would test for this is to go to a AT&T store and do a "vs" on # bars/holding bars and the DBM rating under "about phone">"status".
If they are both the same then you may need to call AT&T about this. (I hope you don't have to call them 10 times like I did with the big red.)

Tried turning off my speakers here...Still bad. I mean the speedtest won't even complete. I'm stuck on the upload, the download was .74Mbps... 185ms ping. The signal isn't consistent. It says LTE then it goes away. I'm just bouncing around between HSPA, LTE, and nothing at all. Despite the phone not moving...This thing just can't stop hunting for a network.
Under the battery use, clicking on the graph expands it and shows the "mobile network signal" and the bar is 90% or more all yellow and some gaps of nothing even. Some slivers of red.
EVERYTHING else about the phone is amazing...It's just behaving as if I was in the middle of no where or something, but I'm in a small city.
I now know why my friend is ditching AT&T for Sprint I guess...But I'm screwed there too, no LTE and ugly phone design. It's like the HTC One is just some giant tease. A mythical Unicorn. Magic dragon. I just keep chasing it, but I don't think I'm ever gonna catch it

sprint is going to have its version of the one x - the updated evo, i believe, due out this month.
but you should just take your phone back to at&t. others have done so and gotten replacements.

So does it act like this:https://www.youtube.com/watch?v=rDxJoGv3FLA&feature=channel&list=UL
If so, you likely have a bad phone.

so it's a thing? like i can just roll in and be like "i think this phone is broken..." and i'll get a new one? and it's common?
okie dokie. i'll go do it tomorrow.
my internet is kinda like that video. slow and connection is lost.
BUT i have seen it really fast on the speedtest.net app.
on a side note, i did a factory reset and since (just about an hour now) i have not yet seen the constant connect/disconnect issues that i did before.
so it's pretty slow inside my apartment but it's at least consistent. outside it was fast on the LTE. 15Mbps down on the speedtest.net app. again the connection did not drop.
so i can deal with a little slow inside... in the bathroom the densest part of my apartment it was down to 1 bar but still, the mobile network was connected and despite it taking foooooreever to download an app, the play store at least did not fail on the download.
so better, but not perfect.
trying the speed test right now, it failed. thing says 4g lte up top too...why it would fail when the thing says it has signal, i just don't know.
can a phone be broken in this manner? intermittently work? i would say then at that rate its the area. bad signal in the area. ...and if i went into the store and said i want a new phone, i feel as if though they would just say it's the area you're in and the phone is fine... but how is it bad signal when it says LTE on there? and when every other device (a phone on Sprint and my wife's iPad and iPhone on AT&T) work fine? i can't imagine it's a bad area or apt. insulation. but how can the phone be bad if it works "some" of the time?
anyway. i guess i'll go see if i can trade it in.

Mobile network turning on and disconnected with 3 bars 4G LTE
I experienced the same problem after using HTC One X for the first day. I was able to get almost 30 M download and 26 M upload in my house on May 6th but lost the connection to mobile network on May 7th at the same location. When I turn off Wi-Fi, phone tried to connect to mobile network but went into the loop of turning on,disconnect while mobile network button is on. I went through 3 AT&T tech service even got a new sim and did factory reset but the problem just won't go away. The last AT&T tech service told me it is a defected device which I really don't agree. I think it is more an issue with HTC One X working with AT&T 4G LTE. I hope HTC & AT&T can solve this problem soon.

Data dropping

My phone has dropped data randomly two times this morning. I could only get it back by doing a switch to airplane mode. Anyone else with this problem? Is this a phone issue that I need to get a new one?
Sent from my HTC One X

Mine has dropped several times. when coming to and from work. It seems to always happen when it connects to wifi. when i leave work and its wifi, i lose all signal entirely.

I don't use wifi though that's the thing. I called ATT and they said it may need a new simcard......which this was. So I swung by and got one and the lady at the store said that my phone may be going bad! LOL wow I love how they train their people.

YES. Most definitely, this is the same problem I'm experiencing. I had another thread posted about how the 4G icon was lit but there was no signal. The icon now seems to be a little more accurate...But still.
At home I switch on WiFi so I don't run up my data but if I look at the settings for mobile network the status underneath in gray text keeps showing that it connects and disconnects. Endlessly. The phone isn't moving. My wife has signal on her iPad and iPhone (I know those are 3G).
I have to turn on airplane mode and then off...Then mobile network on and it seems to help a little. However it's still super spotty.
This is pretty much only indoors but I don't know. I'm going to go around town and try it out. On their coverage map I'm in a big zone of LTE coverage. Outside I have seen 30Mbps on LTE using speedtest.net app. So I don't know. I thought it was very odd given the houses here in CA don't exactly have super thick insulation and every other cell phone (Sprint, my wife's on AT&T, etc.) seem to be AOK. It's just this new One X that just can't stay connected to the 4G.
Going under settings > about > network ...
I see my signal strength....some readings are...
-109 dBm 4 asu
-101 dBm 6 asu
-107 dBm 2 asu
I have no idea what values I should be seeing - what is considered good?
Mobile network type says HSPA. Service state says in service. Icon up top is 4G with one bar. If I turn off WiFi I could not load a web page or anything. That's what annoys me. I usually see like 2 bars and that's fine...But if I see the damn bars and the 4G icon....I sure as hell expect the data to work, even if a little slower.
It's just SUPER flaky. Again outside seems to help but to be honest I haven't sat and watched it. For all I know it could be connecting and disconnecting over and over outside as well but just have a stronger connection when it is actually "on."
I'm annoyed and speechless. I'm not in the boonies. I've never experienced anything like this before. I'm actually at my desk in front of a window. Uh...WTF?

Just picked up lunch and watched the data while on the trip.
This phone is unusable. It's gotta go back. Well, I guess it's welcome back Sprint. Sooooo disappointed.
All I got was HSPA. The only time I get LTE and those fast 30Mbps down is at night time. AT&T is such a joke and their network is NOT ready for this phone.
I'm in Palo Alto, CA. It's not the middle of no where. This is embarrassing. Either that or somehow I have a defective phone or SIM card or something I have no clue here...It's really really bad and I'm obviously not the only one.
3 days and it's been horrible, the only reason why I didn't notice sooner is because I've been using the phone on WiFi most the time.

how fast is the HSPA you're getting?

1-3.56Mbps down and 0.04-1.03Mbps up.
Out on the street downtown.
Best I've ever had was at night on LTE 30Mbps down and like 17Mbps up.
All to the same test server. Trying servers several states away it varied, sometimes I'd even see 20Mbps down to a far away server.
Again this is all WHEN I'm actually connected to the data network.
The thing just can't hold a connection. Constantly dropped.
edit-- ok so right now same time of day, servers, etc. Sprint's 3G is a little slower, but at least I'm not getting dropped.
and on a side note, i got a REALLY helpful lvl1 tech support lady on the phone. much better experience than i thought. there was an issue in the area before. but basically i'm going to give it another shot. if no good tomorrow, swap for a new phone. they'll call me back friday and we'll see... crossing my fingers.

Any update on this? I've got a new One X and work night shifts twice a week. I've notived tonight that the data drops when the phone is idle and obviously nothing pushes.
There's got to be a way of turning this off. I can see why HTC would call it a feature, but there has to be a flag or a switch somewhere....

Pattern of 4G Disconnectivity (Not LTE)

Curious to see if anyone else has this same problem. I've looked around but can't find anyone that can replicate it.
Phone is running 4.0.4 with ATT's 2.20.502.7 710RD. Ever since I bought the phone, 4G connectivity has repeatedly been interrupted; all bars drop, service is gone, and it doesn't return for at least 30 seconds, if not a few minutes. I've been running the phone on a non-LTE sim card, so I assumed something in the network was causing a bug.
Behold, LTE. I got the LTE sim card, installed it, but still noticed the same pattern. If you look at the photo I've attached, it seems like the 4G connection gets disconnected every 15 minutes or so (red bars under "Mobile network signal"). It literally looks like there is a perfectly measured interval of time between the 4G disconnects. BUT, interesting thing you can see is that, during the time my HOX was connected to LTE, there wasn't a single hiccup. The entire green sector in the middle of the same line, "Mobile network signal," is from LTE. The left and right sides of the line, though, mark the 4G service area (my home), plagued with red marks of disappearing service.
AT&T says it has nothing to do with them; for once, I believe them. Does anyone have any advice or observations? The phone doesn't have insurance on it, so I may send it back to HTC and *hopefully* have them figure it out.
Cheers.

Won't reconnect to cecll network after dropped signal

Enjoying my new Nexus 5 and was previously using my HTC One that never had this issue. I have very poor T-mobile service in my neighborhood and I have a cell booster in my home. Problem is that since I switched to the N5 if I loose my cell signal for more than a minute or two it will not reconnect. I get the exclamation point in the notification shade saying it lost tmobile signal. 9 times out of 10 the only way to get signal again, even after driving into a better area, is to rescan all the networks again and select tmobile where it re-registers on the network. As of now I ahave to do this everytime I leave my home. Does anyone have a similar issue or a possible solution?

I have a similar issue, when my phone has low signal and disconnects from the network, it will reconnect and show i have signal strength, i can surf the internet, but cannot make calls or send texted messages, phone shows "cell network unavailable", if i reboot the phone or turn airplane mode on and off it reconnects properly.
