I am on my second International HTC one X and both devices would lose the carrier signal quit often... I would either go to airplane mode, or turn the network off and on and it would grab it again. Sometimes it would be good for the day and other times, I would have to do it a few times....
I wanted to think it was my carrier having issues (MTS in Winnipeg MB Canada)... however, this has never happened on my many other devices. Now I wake up today and turn on the mobile data, after awhile... it does not connect, under settings it says disconnected because service is unavailable. I tried reboots, restart, airplane mode, checking apn settings.... on my last reboot, it says No signal/emergency calls only.
So now I am fearing a hardware issue (but I find it odd it happens on both my one xs).
I love this device and aside from this potentially huge issue.... I have no complaints, so I will ask here and see if you guys have any solid input.. before I contact htc!
I also popped my sim in and out, as of right now...
Thx in advance.
**update: it almost seems like putting wifi on, knocks out my carrier signal.... after an hour of doing the above things, I turned off wifi, went to airplane mode and now my signal and data is there (it makes no sense) and it is quite a hassle
The weirder part is, it seems to only be in the morning.... once I am up and running, I do not seem to have many issues through out the day, but If I put wifi on long enough... It goes to no signal/eventually....
If I do not put on wifi, it either does not drop.... or I am not noticing.
I've just begun having network problems but I'm not sure it's related to your situation. I'm in Australia on the Optus network.
It happened suddenly yesterday. Service completely cuts out for extended periods. It will occasionally come back on for a short while (long enough to download all my sms) but will then cut out again. When the signal does briefly come back in, the signal strength is decent: it's an all-or-nothing proposition.
Did you manage to resolve your situation? Would be interested to know what resolved it for you.
I've had this phone since early April when it was released here and the is the first issue I've had with it. I haven't done anything new to my phone in the past week so I'm finding this strange. I'm running Leedroid 4.0.0 but I've had that installed for weeks without issue. I'm worried it could be a hardware issue.
I'm going to try reflashing it tonight to see if it's a software issue.

Got a strange issue here. My wife and I have had evos since release and 4g worked fine on both when we got them. We're in Boston and since Boston didn't have official 4g until last week, neither of us have used the 4g radio until we read that boston was flipped on last week. On both evos, we're finding that when we toggle 4g on, it takes the normal ~20 seconds to turn on and then it scans for a second or 2 before turning itself off. After turning off, it turns on again and repeats this on/off routine indefinitely. I am only able to stop the loop by pressing the "4g off" button while the radio is scanning for a few seconds. The radio then turns off and stays off. On my wife's phone, the scanning only happens for a split second so it's almost impossible to stop the loop. Her battery dies in ~4-5 hours because of this.
Both evos are stock 2.2 and both pretty different launcher/app setups. I've tried removing common apps between the phones with no luck. I'm at a loss for what might be causing this. I've searched and found this thread but there is no solution:

Next step is to call sprint but that is always a last resort. Any ideas?
that's pretty weird. From what i know this happens when you root and flash roms/kernels. Your mac address gets changed. I'm having the same issue atm, but my evo is rooted.
Either your mac address was changed for some reason, or your rsa keys are gone.

i read about people losing 4g due to rooting issues and keys getting lost. but from what i read, it seems these people are able to turn on their 4g radio without issue but it just scans forever even though they are located within range of a 4g tower. i'm seeing something different here. the 4g radio goes into an on/off loop and barely scans at all.
Not sure I'll be much of a help, but....
Make sure you are outside in a guaranteed coverage area. 4G signal doesn't have the penetration or range of 3G/EV or 1x Voice radios. Confirm that you have 4G signal in that area with someone else who has a 4G capable device.
Then, if that doesn't help, you can go for more extreme methods, such has completely reset one of them back to factory, redo your data profile and test again.
If that doesn't work, you'll probably be stuck with calling Sprint.
If it were me, I'd do the outside and confirm 4G first, then call sprint and see if they can refresh your profile or something before going to the extreme of hard resetting back to factory.
Just because the maps say you have 4G, doesn't mean you do right where you are. There's an app in the market that folks are using to find actual coverage, called Mapviewer by Sensorly. That may help you see where others have reported good signal.
GL!!!!!
thanks for the tips. when i was playing around with 4g back when i first got the evo, i found that i could turn the 4g radio on even when there was no 4g signal and it would just scan for a long time. is this still how it is supposed to work or did they implement some auto-off feature such that the radio turns itself off if it doesn't see a signals after a second or 2? because right now, the 2 evos in my house turn off immediately after turning on and then continue the on/off loop. so it doesn't seem like i can get the evos to behave properly even without 4g signal. i may try calling sprint to try the data reset.
I would give it some time to ramp up - I started in another thread how all of a sudden I'm getting 4G in NJ - and we're not supposed to have it yet at all. I can connect, but it just cycles through connected and diconnected (making it essentially unusable). I would imagine it will begin to normalize after a while.
edit - misread the op, sounds like you're having a different kind of issue. nm
Also, that is how the antenna works - it will keep scanning indefinately until either the battery is dead, or it connects.

nah he's having the same exact issue as me.
Here is the order of what happens:
1. Turning on...
2. Scanning...
3. Authenticating with sprint.. (sometimes you see this, sometimes you dont)
4. Turning off
5. Go back to 1, and repeat
^^ From what he said, that is pretty much exactly what it sounds like. And that's the same problem I'm having with rooted phone.

that's pretty much it except i've never gotten to the authenticating part since this issue started. also, my phone scans for a few seconds before the 4g turns off. my wife's phone turns off almost instantly after the radio finishes turning on. this is the biggest issue because there is no way to interrupt the loop on her phone. even a reboot with battery pull doesn't stop it.
performed a hard reset on my wife's evo and that fixed it on her phone. mine will be tricker because of customizations. what a PITA.
called sprint and the tech support basically said the 2.2 update has caused lots of problems and they are waiting for "htc and android" to release fixes. so, of course, not sprint's fault at all. she told me just to use 3g and not 4g. pathetic.
did the hard reset on my evo and now the 4g radio won't turn on at all. it just sits on "turning on 4g..." for a few minutes before coming back with "unable to start 4g". i've tried 3 different types of hard resets (buttons, clear storage, and ##786#) and all with the same result. sprint is telling me my phone may be hosed but they won't give me a replacement because a fix is supposed to be released eventually. ugh...
Did anyone find a solution to this problem?
I was in Las Vegas on Friday, and 4G worked fine, but since then my 4G is doing what the OP said. I haven't changed anything in the Rom or Kernel.
Thanks!
A lot of times lately I'm losing my 3g Mobile Network, my signal strength will be a full 4 bars and I still get the issue. Usually if I reboot the phone it will come back. I'm starting to think it gets lost after it connects to WiFi and then when I disconnect WiFi. Anyone having this issue? If so, are there any tricks to getting this to stop?
My phone is completely stock 2.2, no root.
I'm not sure which of these events may have triggered my intermittent lack of 3G connectability but these are the only changes I've made since this started happening:
1) Upgraded to Froyo.
2) Performed the .dun trick to allow 3g Hotspot. (Although I never use it, I tested it a few times but this problem happens without the Hotspot turned on.)
Did you do a factory reset after the froyo update?
Sent from my Incredible using tapatalk.
Nope, I used the SD card method before I got the OTA. Have never done a factory reset.
I have this as well, be it im on a different carrier (Cricket) but it appears in all stock htc froyo builds.
My assumption is that is the radio being used. of how HTC's implementation of Froyo interacts with the radio.
I switched radio's and havent had it occur on me while in the OS yet, and it does occur sometimes on boot still, but if it loads on boot it seems to stay up and stable.
My trick is to turn airplane mode on for about 30 seconds (30 seconds after i see the airplane icon), then turn it off, i assume this reloads the radio, when the brings 3g back.
I can also read my nv settings with qpst and reflash them back to the phone with no changes, which causes the radio to reload as well, and 3g ALWAYS kicks back on.
Also updating the PRL (even if its the same PRL) seems to work as well (assuming this is due to the reboot, which reloaded the radio)
The radio i am using now is:
2.15.00.09.01 - Seems pretty stable, except the occasional one of at boot, which is fixed by airplane on/off.
From what i can gather this nothing to do with custom roms, as many offical Verizon customers on Official NON Rooted 100% completely stock phones have this as well.
Hopefully HTC/Verizon will fix this in a MR update.

I'm gonna try that next time it happens. Easier than rebooting, then it wont bother me too much.
I had that problem once, and never saw it again.
One problem that just happened for a second time today is I cannot send or recieve MMS. HTC had me reboot the phone and call VZW support, of course they yelled at me for not using a task killer -.-
The reset worked, but I'm going to get annoyed if this becomes a regular problem
I have same setup and same issue. As soon as I made the EPST changes for tethering and hotspot, I started having this issue where I'd lose my data connection completely after disconnecting from my wifi when I leave my house. A reboot of the phone fixes it but it's still kind of annoying. It happens I'd say about twice a week.
I have an interesting problem, I couldn't find this issue on anywhere else therefore I wanted to share with you;
Sometimes after 3-4 days usage (in this time period sometimes I use wireless, sometimes 3g or sometimes turn off the connection), my phone gets stuck on edge connection and never goes to 3g unless I restart it.
I tried switching air plane mode on/off and several other things. Only restart fixes this. This is not a new issue, it is happening almost for 6-7 months (on 2.1 and 2.2). It doesn't matter much to restart in a few days but I wonder anyone else has the same problem.
Am I the only one ? surprised
Hi,
Wondering if anyone is experiencing this issue.
Got the uk version of galaxy nexus, GT-I9250 ordered from an online store from the us. Only within the first 24 hours I experienced a time where I suddenly lost my 3g.. the signal bar shows no service. Only way to get back is to reboot phone.
After it happened few times and doing some testing, it turns out the radio just shuts down. Going to settings, about then status shows radio off. Going to the secret menu that gets accessed by typing a nmber also says radio is off. There is a button to turn radio on.. but it does nothing.
Tried factory reset, .didn't install any apps. Still issue occurred. Also noticed at random time before the total radio sshutdown, I do lose 3g few a minute then comes back.
See my screen captures showing issue attached.
The preferred network type when the radio works is shown as GSM/CDMA auto. During issue its unknown as shown in capture. Changing from unknown to gsm/cdma auto after failure does nothing.
Of course ttried to turm 3g on/off.... airplane mode on/off.. nothing works except a reboot.
I am on Kk1 radio. I didn't try kk6 as i didn't want to touch the phone in anyway to void warranty. my buddy has same phone but doesn't experience iissue. Same phone, same carrier, same city.
Any thoughts?
Maybe exchange it for a new one? My only advice

Have you tried running logcat to see if there are any logs to suggest whats crashing your radio?
Mine done exactly the same as yours and I am with Orange UK who stated I have a faulty sim card and are sending one out in the post to me so hopefully if that resolves mine you can also ask for a replacement sim card as well.
P.S I found that speediest.net knocks wireless/radio off sometimes and also wireless on mine can totally freeze as well so hoping this will be fixed asap by google.
I have same issue - loosing signal completely just with no reason very often. Turn phone off/on - works fine. I have brand new sim card and phone from Handtec, Vodafone UK.
Ditto for me as well. Purchased from Expansys, second round. It will move between 3G and H then shut off. Happened once so far. I'm using a MicroSIM with an adapter, both worked fine and are new.
I'll be watching this very closely. Someone with a Google account can post this to bring it to their attention?
Happened a second time but came back on. Attached a screen shot.
It does happen where the signal is lost, then comes back. That could happen few times before it goes down and then never comes back up at all. I used a program called signal alert to tell me when. It happens. I found that during the day signal is fully lost a number of times but it comes backafter less than a minute. at some point its lost and doesn't come back and only reboot fixes.
Bmstrong, the capture u showed me shows you lost data, but it seems you still have voice. Look at the screen I posted, u can see no bars what so ever in my signal meter.
When the issue occurs, its random, so by the time I find out and i ran alogcat, I would have missed it. Alogcat only shows me few minutrs before. However, I kept looking at alogcat after the fact and there was nothing that i could see that explains this.
I did try another sim while the trouble is occurring and no use.
I have requested rma from where I bought it and just waiting for authorization. Will share my experience with it and the store after.
Thanks,
Bmstrong, go to settings and about, then status to see if it says radio off. If it doesn't then it either your really lost 3g..maybe coverage or a different issue. In my case radio says its off and never comes back.
sorry to post a little off topic. but how do you see the first screen in the OP's post?
I'm getting this issue too, does anyone have any more information or has resolved this?
When going into the phone info screen does pressing "turn on radio" work for anyone? I have to do a reboot before I get signal back.

Luxferro, type *#*#info#*#* in your dialer.
I have owned this phone only for three days now, coming from a DHD.
Today I installed the 1.28 update and since then my cellular signal has been all over the place. I normally get a solid 5bar HSDPA signal where I live and since the update I have had nothing but issues.
My Sim card seems to be rejected (I am baseing this around the fact that when the radio seems to cycle I get a message saying "preparing sim") but aso it seems to just lock up entirely. Earlier I thought I had a signal only to make a call and have it fail, I tried to cycle the power to the radio by putting the phone into airplane mode but this didnt work so had to do a hard reset which then allowed me to make a call, but the call froze after 5 minutes, again with a seemingly locked up radio.
Any one else got these issues, as my phone is effectively a small but expensive tablet at the moment!
I have that issue BEFORE the 1.28 update. The other day my wife rang me at work and whilst we were talking we were cut off but my phone still showed as connected with signal. I figured she maybe lost signal herself. I tried to ring her back both on her mobile and the land line and my phone would not ring out (as far as I was concerned) I tried to put Airplane mode on but it didn't work so I had to reset the phone.
I haven't had it since but the strange thing is even though the phone didn't give me any indication that it was ringing out my wife said that both her mobile and the land line rang.
It seems strange that I couldn't toggle the radio/airplane mode or hear anything but the phone did actually ring out. Maybe the issue effected the radio and speaker? That's something to test if yours does it again. Ring a phone nearby to see if that does actually ring?
Update from yesterday, I currently have a signal as I am typing this, if however I make a call it will connect and I can listen for a second then it drops with the signal dieing. Followed right away by coming back up.
A reboot seemed to fix it for the moment, but not sure how long for. Next step is a factory reset for me and see how I get on from then.
AFAIK, the radio isn't updated?
I have taken it back and swapped it for another one now. Just waiting for it to charge then I am going to do the FOTA update and then install everything. So far though so good and the three calls I have made/recieved worked perfectly.
Seems to have beena faulty handset *fingers crossed"
