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.

Had the same issue. Out was my sim card. I had been using my original card which wasn't compatible with the new technology. Once I put in the new card it was all good.

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] Unlocked Sensation wasnt too Sensational

Im fairly new to the phone game but i know a little bit. I traded my inspire to a Sensation, unlocked it myself. Everything worked finr except my Data i couldnt use the internet in any way. I called 611 (atts customer serv) and they said the connection was rejected. Luckily i was able to convince the guy i got it from to trade me back and give me the extra money i gave him for the trade. Was i just being a dumbass not knowing what to do or is this an issue. On the phone i went into the carrier and APN and it all seemed fine... Just curious because i would still like that phone but of course want my data connection Thanks
Also someone told me that unlocking/flashing phones will drop them down 2 data speeds (4G-2G/EDGE) Is this true?

Stop listening to ignorant people.
As for the problem you encountered, I believe you got the wrong Sensation. You need the Z710a for AT&T.

lianw is correct. Many of us are happily using the z710a on at&t.

Same guy as Smolt here for some reason it wouldnt let me log back in and after an hour of screwing with it and password retievals..... Well here i am... How do you tell the difference between the 2 Sensations? Did you have to call611 and give them the imei # to use data?
Ive got a post under my newly given moniker, if you find the time check it out. Any help is greatly appreciated and always thanked

So you traded the Sensation back to your original phone, so you no longer have a Sensation, and you still want to know why you were having problems?
People don't waste your time trying to figure out his issue, he doesn't have the phone anymore to try and fix it.

Because not only are people wasting their time on answering your question, but you are also cluttering the forum...who knows, you may never get a sensation again or have the issue if you get the correct sensation and this thread them becomes trash.

unless the sensation supports the at&t 4g or 3g bands, you're limited to edge. that's what happened to me when i was using the inspire on t-mobile.

I think only bell or Virgin(from Canada) Sensation have 850 frequency, it is working fine on Rogers with 3g or HSPA after unlock(which i think it should work on at&t as they are using the same band). I hope this could help u a bit. T-mobile sensation doesn't work on at&t because it doesn't support 850.

I'm using the bell sensation z710a and get ATT 3g speeds with no issues.

HTC Sensation lost gsm signal.

Hello all. I'm using sensation for about half a year. Everything was fine before a week ago. He's loosing signal, disconnecting from the gsm netwotk, and voice packets are loosing sometimes. Can somebody tell me what can I do to make it work as it was. The most interesting thing is, that I've done nothing with it... Not even updated it... Help somebody )
Sent from my HTC Sensation Z710e using XDA App

Maybe you could talk to your network provider? They may be having issues in your area, or perhaps you could try a new sim card and see if you still get the problem.

Can it be a hardware problem, cause there are 4 pair of contacts on the back cover, that are working as antenna. i've cleaned them the first time i had the phone, and didn't touch till today. it was a T-Mobile one, bought in US, i cracked it, and it worked fine. i think my gsm provider done nothing in my area, cause i have the same problem in other part of the city also. And how can changing sim can help me?
Thank you!

Signal strength bad?

Anyone else think a radio update will fix this seems odd now it's full bars but just a second ago it was no bars or is Anyone else noticing this

No bars again on and off wtf
Sent from my HTC VLE_U using XDA

I went into the About section of the settings and then Network and watch it constantly switch from HSPA to UMTS and something else, but the TMO 4G icon remained at all times even though the signal strength indicator went from 1-4 bars.
Something is definitely messed up with this phone!

Yes many others including myself has the same issues. As suggested in other threads call up HTC to file a complaint so that they can escalate it to the tech department and push them to release an update for the radio. I even went on twitter to stick it to the man lol.
Sent from the (problematic?) One S.

yes, Its a bug in the radio, not a fault with the handset.. I too have it as well as 100's more users.. There have recently been some OTA updates released with a new radio which fixes this issue... So hang tight it will get better

Some was saying that it didn't work for them and that the signal issue got worst after the OTA update. i'm really hoping that it's the radio. I went to the store to swap SIM to see if that would resolve it for me. so far.... still the same signal issue, unfortunately. I have two days left to return it and I'm really considering it, even if I have to eat the $50 fee..

Mine was doing that. But not no more. All I did was put it on WCDMA only haven't had that problem since
Sent from my HTC VLE_U using XDA

The above ^^ was suggested to me by HTC but didn't work.
I'm on my second One S with the same problem. HTC advised I exchange it. I did so and second one was the same. They then said they wanted the phone back in for investigation and repair. I'll now wait and see what they do with the phone, if anything. It's been sent back and the ball is in their court. I get really rubbish reception on the One S when there is a strong signal in my area. All that said the signal strength readout bounces about all over so something is amiss. I'll report back once I hear anything or I get the phone back.
I've not had the software update BTW.

I'm currently doing this and it seems to do a little better. I'm on my second handset and the issue is still there. TMobile employee with the One S are also having the same issue so. I'll wait to see if the software update fixes it. If not I will have to tell my phone insurance company to replace the one s with a comparable phone. Then I'll stick it to HTC lol. My last phone was a G2 and it was a solid phone that can still run with some of the big boys and reception was fantastic.

SIM problem on my One XL (LTE)

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.
