I applied the update late Friday night and have not been able to get a 4G signal since. I'm normally in a strong 4G area and had not had any problems like this in the past except for the nationwide outage of course.
I've tried battery pulls, toggling LTE off and on and even did a factory reset. I then talked to tech support and they did a few things on their end that were unsuccessful. They then told me to get a new SIM card but once again, no luck.
Tech support is at a loss to explain what is going on and has escalated it to the higher level of support. It can take up to a week for them to get to a ticket so I guess I'm SOL until they take a look at it.
Anybody else having 4G problems since the update?
I haven't applied the update but have been stuck in 1X all day as well. I also pulled the battery, switched back and forth on Rev A, and toggled LTE. Nothing. Was going to revert back to a saved ROM next. My wife's phone happily receives 3G.
Did the update Friday night and 4G is as strong as ever.

My 4g is also working. What is weird is when I loaded a ROM I lost all signal. I loaded another Rom and nothing. I had to load radio file in hboot and I was back in business.
yea in such circumstances I had reflashed the radio and it works just fine, give it a shot
Received a replacement today, popped in the SIM card and am back to 4G. No idea what happened but the update is definitely to blame.
Yeah I got mess up too with the new update. Had to get a new simcard today and it work ok.
4G working just fine for me also

glad you got it worked out. I would have reflashed just the radio to try and fix it.
Having this issue as well since yesterday (7/11). Loaded Th3ory 5.0 with the newest radio to two different Tbolts (mine and a coworkers) and we're both experiencing the same issue. Flashed different versions of the radio, including the newest one again and had 4G come back for a short period of time before all service was gone again. Not sure if its an issue with Th3ory rom itself and since I cant post in that thread until I make a few more spam posts about nothing to get my post count up, I figured I'd post it here.
in Mid-town NYC where 4g has never been an issue before.
I should add that I wasn't rooted.
What happens if you're Rooted and running a custom ROM and you do a SIM Card pull? I really want to try this method, but i'm scared this will force my phone to download the new OTA update and that i'll either brick my phone or run into some serious issues.
I have had trouble for the last two days getting 4G, never had a problem before.

don't think anyone else is having problems. Might be network issues in your area. Just flashed gingertheory 5.0 yesterday with the new stock 2.0 radio from the update and no problems.
I am having the same issues 4g is gone and only stuck on 1x
Make sure you check your sim and battery cover.

You dont need to pull out the sim card, pulling the battery is good enough. All it does is update the PRL.

I'm in the same boat.... I used to get 3-4 bars of 4G service at my home, now after the update I barely get 1 bar of 3G service. I have to force the phone to lock onto 4G by choosing LTE only.

All,
I have had the One X for just over a week now. Three times, I have had to hard reset the phone because it stops receiving / making calls, and data stops.
I tried searching the forums but it seems like issues are all over the board and couldn't really find something that was exactly my issue. If there is one, I apologize for the duplicate post.
Regardless, when the phone is in this state, it appears like everything is working. It shows I have great signal, the little 4G icon is there, indicating that everything is working.
Anyone else have this problem or could I possibly just have a bad unit? AT&T already swapped out the SIM card thinking that might fix it, but no luck.

I think you should swap out the phone as bad before returning it if that's the only issue you're having. mine seems flawless in that regard. I haven't missed or dropped a single call.

I don't recall ever having that problem. Mine was pretty random too, in fact it got so bad yesterday that I missed several important calls.
If I would restart the phone, I would get all my missed text messages and the voicemail (google voice) would tell me I have messages waiting..
Very frustrating.

I thought that might be my problem too, but where I could stand in one place and have the problem, restart the phone, and then not have the problem -- that leads me to believe there was something wrong with the phone.

My X started out ok, but these last couple of days I have NO signal anywhere. Also SMS/MMS is barely working. (and when it does, people are getting multiples) And its dropping pretty much every single call.
I just called my corp store, they have plenty in stock. I'm going to go exchange it. Should I ask for a new SIM also?
And my screen is perfect, here's hoping I get another good one...

However, AT&T's LTE phones are notorious for connection problems on non-LTE market. These LTE phones use a new APN called pta. I just had the same problem while traveling through PA yesterday. Lost data connections many times and had to reboot the phone at the end of the day to regain data connection of any kind.
So, it is AT&T's service and also the phone firmware that can't properly handle the fact that it can't receive any LTE signal in certain areas.

return it and get another phone, besides the One X, it's all hype anyway. The HTC vivid is a much more solid phone.
I had almost the same issue. My device was on wifi and would at random times just stop pulling data. Or at time just not make calls. I tried trouble shooting it but I was basically told since I didn't have it long I should get it replaced. I replaced it and the new device is perfect. I have not once had that issue again.

Who said I'm going to reture it. OneX, regardless all its problems is still way better than any alternatives AT&T have. There is no such thing as problem free Android phones. I've being many of them. They all have problems one way or another. Vivid with its ancient S3 CPU and SD screen just plain sucked. My SGS2 can kick its butt.
For me the form factor of One X, LTE speed, S4 processor and HD screen are the main things I pick One X over any other phones available on AT&T. These software bugs will be corrected overtime.
I just came back from my store. They had plenty in stock but said when that runs out, they have no idea when they will see anymore.
I have a brand new 1X, and a new SIM card. Hopefully this one works.
I stopped by a vzw store to look at the gnex and my hox side by side. I've decided to keep the HOX. Screen on the gnex was way too bright and I ran quadrant side by side on both phones. The hox blew the gnex out of the water.

Bought mine yesterday and this same issue happened to me today. Had full reception on 4G but could not send a text or place a call. Happened twice today, and I dont know if I want to return it ASAP or if its software related and may be fixed.
I had that problem 3 days after buying the phone. Data, calls, texts..tons of problems. Phone was unusable half the time. I went and exchanged it for another one. I am now at 6 days with the new phone. No problems. I hope it lasts.
Hi since I can't find a forum for the One XL I assume it's shared within this one.
I just got my One XL yesterday and it's been having what seems to be a SIM card problem. The phone will be normal sometimes but will lose all mobile connectivity suddenly. Is this a known problem? The connectivity comes back on its on but it could be after a few minutes or few hours. Apart from returning the phone, is there anything I can do? Note that WiFi works perfectly.
Yes sir that would be a common issue among the hox .

When you say "XL," so you mean an imported XL from Asia? Rogers? AT&T? The AT&T's the one having some radio issues. I don't think the Rogers' is. And if you imported yours there could be a number of reasons you're having connectivity issues.
@barryH_GEG: I live in Hong Kong and the One XL has the right bands for 4G and HSPA+.
@tyshemi: is there a software fix to this or is returning it the only option?

Gentlemen,
What the h.. is with this phone? I got it as well last Friday and I have exactly the same problem - it loses all mobile connectivity and only emergency calls can be done .. for which a SIM card won't be needed. It doesn't look like a software pronlem to me, it looks more like a hardware problem! I've seen this behavior immediately after I received the phone and I immediately went with the phone in a Vodafone shop. The guy did not look surprise at all. He took out the micro SIM for couple of times and after wards it worked OK. I went home and after couple oh hours it happened again!!!
@ HTC developers:
Gentlemen, are you joking with this device? What's going on in the testing team?
Indeed it is a LTE phone - and it is known already that there are lots of problems with the 4G software, but the SIM card not to be seen by the mobile? How could this be possible???
Please do something about this!
I will send back this device immediately!
Cheers
I myself have exchanged my HOX for this issue twice now. AT&T knows about this issue and refers to it as a manufacturing defect with the SIM card reader while not in a LTE area.

In Australia, we have this issue on our 32GB One XL. Apparently it's a particular version of micro SIM. One specific version has this issue, the other doest.
I've seen it happen a couple of times on mine since I got it. If it happens again, I'm going to put some very thing pieces of paper under the sim card to make it marginally thicker and press firmer against the contacts when it's inserted.

Hi guys,
Just to give you an update about my HTC ONE XL. Unfortunately, I have only bad news about it !
I went yesterday to Vodafone shop and they changed the micro SIM card. They gave me a different one - also a brand new one, and I have the same problem, the phone loses the connection with the SIM card. Since yesterday it happened already twice! I've seen some discussions here about the WiFi. Just to mention that in my case the Wifi can be used, only the network is gone and stays gone until I restart the phone.
HTC ONE X also loses the connection with the SIM?
My micro SIM card does not have a 4G subscription anyway..
Cheers
Try putting tape on the plastic side of the microSIM to see if maybe you can get a more solid connection?
My One XL would keep loosing reception and saying "no sim" even though it was clearly working. I deactivated my SIM pin and it seems to have stopped dropping out and saying "no sim" Give it a try.
I have One XL and I have no sim issues, it could be the piece that you use. As for the signal drop, it does happen to me sometime, and I think it tries to connect at LTE then goes back 3G. Try to force 3G only then try.
Setting on network menu could help too. Try *#*#4636#*#*

Been having the same issue and found it in the logs. Not sure if other people are seeing the same thing though. Post with info.
Hi guys,
I sent back the phone last week and yesterday I got a new one with a "newer" IMEI. Since yesterday, the phone did not lose the connection with the SIM card.
I was told that, indeed, some of the first HTC ONE XL modeles released on the market had the problem described by us on this forum/topic. The nature of the problem, hardware or software is not known to me so far but I believe it's a bit of both..
Cheers
This happened to me and updating radios to 1.88 or higher fixed it. did not work well with 1.85 radio. Radios dont come with custom roms. They have to be installed separately or with a ruu. There is a radio thread in development. You must be rooted. Ive only had 1 person tell me they still had problems after updating.. if it doesnt fix it, get another phone. Its a legit reason. Main reason for a phone is to make calls. kinda hard to do that with no mobile connection. :crying:
Edit: here is the radio thread. 1.88 or higher. 1.88 is my favorite. The telus seems to be great also. http://forum.xda-developers.com/showthread.php?t=1694012

i have question though.. the guys who have sim problem does your network drop from 3-4 bars to 0?.. in mine i have noticed that it actually drops to 1 and then only goes to 0 bars for 2 sec.. then catches up... but if i keep it to gsm only mode.. i get full bars all the time... what do you guys think is the problem.. network or the phone has bad way to switch between the network types?
and jsut in general the network fluctuates a lot on this phone.
I got a new one x 2 days ago and its been working fine. However, my battery died last night and the phone turned off.
After plugging in the phone, the phone restarted but it would not connect to the network. I went in the settings and it said the network was disconnected. I tried changing bands from lte to gsm... nothing worked.
I restarted the phone a few times, still No signals.
I then did a factory reset and the signals came back.
I am not sure what happened. is this a software issue?
PS: I should add that this is a Rogers One X that I unlocked. I disabled all of the rogers apps
anyone?

Yes a lot of mobile network issues as well as dropped calls and freaky wi if. Im sure they are looking in to it. I exchanged mine for same reason. Hopefully the promised soon update will fix it. Normally restarts fix it. Sometimes it takes multiple restarts. More than one thread concerning these mobile data issues in general. I'm on the new Asian 1.88 just for those issues. Fingers crossed its fixed. Let u now in a few days at most.
So its software issue and not hardware right?

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 .
