Inconsistent data connection

HI folks, i'm not sure if this is a well known problem or not, but i thought i'd give it a try. Ok the basics of the problem are that i can be on my mobile browser or any app and you can see the upload and download indicator arrows in the taskbar working away just fine, then randomly, even if the signal strength stays the same, i will lose the download arrow, and the upload arrow will stay on. At this point I cannot access the internet at all and sometimes this does not start working again until i reboot, and sometimes not even then!! This has happened With my last 4 phones (all android) so it seems like either a problem with my sim card, with t-mobiles network, or with android itself. Is anyone else having this problem??
thanks.
4 phones have been G1, Nexus 1, Desire HD and LG Optimus 3D

I dont have such a problem (orange uk). I think that is a problem with your sim card or network provider

Really? Not a single person? Is anyone in the UK using a nexus on T-Mobile?? Lol

This used to happen all the time on my Vibrant here on Tmobile USA. 2.1 eclair was downright awful. CM 7.1 it was better but without Gingerbread drivers i was stuck with the last Froyo baseband. Even then i still frequently had this issue so i mostly used wifi at the house. Areas with stronger signal i rarely noticed this. But ironically i have yet to experience this with my galaxy nexus. Havent needed wifi at the house yet.

My problem seems to be different for the OP's. I lose the network connection totally; I get no data or no calls. Only a reboot can resolve it. I have noticed this with an AT&T SIM card and an H2O Wireless SIM card. IT seems to be the phone, as I don't have problems with the AT&T SIM card in other phones.

telstra Australia. the data is smooth and fast.

[Q] I have tried everything.. 3G is still messed up!

Guys this is my last attempt at trying to find the problem with my DHD before sending it to the repair shop—and by repair shop I don't mean an official HTC Reseller which is not available in my country!
Here's what I've been facing for the past month:
Without any warnings, my phone started making weird noises
(interferance sound, as if the signal is very poor) during every phone-call, and dropping the call 1 out of 3 times, when connected to the 3G network. ([Edit] Even when I get 4 bars of 3G reception)
If I set my phone to GSM only mode, the issue disappears.
Also during browsing (or any internet use) the signal keeps switching from 3G & H and by doing so the data connection is EXTREMELY slow(and sometimes non-working).
After trying multiple radios(with their ril's) and different ROMs.. and finally switching to a stock rom(and radio), as well as trying other sim-cards/different network, and still having the same issue over the 3G network; I'm starting to believe it is a hardware issue.
Before I send it to the repair shop (and risk getting back awkwardly put-back phone) I thought I'd try one last time here..
Any advise is greatly appreciated..

Looks like a hardware problem. Does everything work fine with wifi?

Nothing wrong with your DHD. It's your provider. The area wherevyou live is probably not well covered with 3G since you said you have no issues switching to GSM. If you don't have any WiFi issues then it's not a privlem with the phone or the ROM. It's bad 3G coverage regardless of the provider

Everything works perfectly--including WIFI--except 3G.
I really hope it isn't a hardware thing, but now I'm 90% sure it is!
I took the phone to the only official reseller of HTC phones in Lebanon.
They told me they'd rather not open the phone up since they've had bad experiences doing so before.
They said issues with the touchscreen usually surface after reassembly.
After googling it seems the gsm antenna is in the sim cover; septate from the 3G one (which i couldn't find any pictures of where it is in the phone)

1. Don't panic.
2. As I explained before, I'm 99% sure it has nothing to do with hardware. Do you know someone with the same or similar issue?

I've tried different locations :/
As i said before, also prior to all that, it was working fine..
I tried my Sim card on a different phone and it works just fine.
I tried a different SIM (same and different providers) the problem persisted.
Still, i really hope u're right!

Hi guys,
After weeks of waiting, i finally got my HTC One x today.
But there is a problem.
When i put my Sim Card in , I get around 2 Bars of signal, and then it goes away and the cross comes over the bars, then the phone says ' Preparing Sim ... ' , then the 2bars appear again, then they go away and the the phone says ' Preparing Sim ... ' , and on and on and on and on again!
I am extremely sad and dissapointed. was really looking forward to this phone.

even i am having the signal problem when compared to my other phones. Nexus sits on full signal and One X keeps moving between 1 bar and 5 bars when holding in hand..have checked the display phone in my local shop which is also behaving same....do all of you have this problem?

I had problems with a cut mini-sim. Got it replaced with a proper micro sim and all is fine.
M.

For the people who have cut there SIM card, make shure you are using the new generation SIM card. Cutting a old generation one can bring issues!

That's weird. My one x is getting signal where my sensation had none!
Sent from my HTC One X using xda premium

Woke up today, no signal and sim couldn't be found.
Was fine last night.
Either T-Mobile deactivated it because they have sent me a new micro sim, the phone is a dud or somehow the cut sim decided to break itself over night somehow.
If the new sim doesn't fix the problem, the phone is going back and ill just buy something crappy to tie me over till GS III.

It has good wifi reception, I'm getting signal in places where I'd have to wave my hands around in the air before. But the gsm signal is really annoying me
Sent from my HTC One X using XDA

none of you have my problem . My is faulty. no reception at all.

Mine jumps from H 3 bars to G (gsm), back and forth. Very sketchy signal.
Using a new micro sim I received today.

Hmm.. I'm using a cutted SIM and it didn't show any problem. Instead, I am getting signal at dead spots compared to my DHD in the past. Weird..
Sent from my HTC One X using XDA

Got a microSIM sent out by my provider. Works fine. I'm getting even better 3G reception than with my Desire S. Sounds like a faulty sim to me.

Strange behaviour you guys are having there. My signal strength on the same telco has been improving switching fr DHD to HOX. Some places with weak signal reception those day in DHD (with 1 or 2 bars) now I could get 3 bars.
Most of the users in my region do not faced such issue, we are seen the coverage is jumping fr H to 3G back and forth rapidly, which we believe is due to service upgrade (cos have been notice such behaviour even in DHD)

I have exactly the same issue with you.
Actually this is my 2nd OneX, the previous one has "yellowish display", but there was no signal reception problem.
After replacement, I found the new one has the same problem described by you. It changes between 3G<->H quite oftern, and I found that mobile radio goes off very often, but then it's showing me "preparing SIM..." and signal comes back again!! Since my SIM on the previous OneX has no issue (at least I used it for 4 days already without this problem), so I don't believe my SIM is the root cause (and mine was the official micro SIM from telecom).

Yes, I agree that for some location that normal phone doesn't have any reception signal, OneX does have signal. And it also changes from 3G<->H quite frequently.

I'm having this issue too. It seems when the phone is trying to talk on 3G instead of H, it doesn't work. So, everytime the signal switches to 3G, I lose data. I still haven't been able to run a successful Speedtest.NET test on the phone.
Anyone have any ideas?

Also gave my HTC One back to supplier. Signal issue became so bad that i had almost no signal.
I found that when i was in a building my signal disappeared. Hold your device upside down and you get better reception. Also made a benchmark test when I got the phone and it score 4700+
when the signal issue started i did a test again and it only scored +/- 3700. Must be hardware. I tried Hard resets and nothing....
Going to be a long wait as I'm in Namibia in Africa and phone was ordered in UK. But overall just an awesome phone !!!

signal loss/dropped internet access on T-mobile UK when switching to orange.

So I phoned tmob up to request that I be opted out of their orange 2g fallback when there is no 3g signal as it was causing my phone to totally disconnect while it switched over. Very annoying as it could take a good few seconds to log back on, causing streams to be interrupted etc. not to mention calls dropping. Anyway they told me its not possible to opt out anymore, but to call HTC to see if there is a setting to allow blocking of orange. HTC said type *#*#4636#*#* in the dialer to enter test mode and switch the phone to wcdma only instead of preffered, to prevent the phone from using oranges 2g network. I'm just wondering if this is any different to selecting that option via the regular personalize menu as this option is there also. I did what HTC recommends and I haven't had the phone disconnecting at all since I called 2 days ago, although now I seem to be using orange 3g and hspa networks along with Tmobile. Maybe this helps people that have the same problem or have tried the regular settings to avoid using 2g in the UK. Any comments or similar experiences please share, sorry if thread is in the wrong section btw!

Quite a useful diagnostic menu. Don't know if that code was previously known

There shouldn't be anything different from you selecting WCDMA only via the regular mobile networks screen and that test page.
Where I live has really bad 3G reception for both Orange and TMobile so I have it set to GSM only when at home.

Most Androids have that key combination to bring up that menu. *#*#4636#*#* = *#*#TEST#*#*

I have exactly the same issue with my Xiaomi Mi-One. Always dropping signal when switching, really F***ing annoying. I can't get t-mob in my house, so it reverts to orange then I look at the phoen sometimes and signals gone, also happens randomly out my area. Sometimes have to restart phone, sometimes it fixes itself. So annoying. 2G in my house seems fine, but as soon as I leave and switch to 3g it loses signal, takes as an age to reconnect as well.

I know this is a thread for T-Mobile / Orange but I am having this issue on Three as well, wonder whether it effects all networks or just networks that use more than one carrier. Three has its own 3G network but it uses Orange 2G signal.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect, just as you guys are experiencing on T-Mobile / Orange.
I have had several instances where my signal has an R next to it as if it is roaming, this would be when it is connected to Orange 2G network, I never had this problem on my Desire HD or Sensation.
Does anyone know of any issues on Vodafone or O2 regarding signal loss?

I had it at first too with my cut- simcard (with a special cutter). After that i thought that might have caused the problem, went to vodafone and they gave me a new real micro-simcard. After that I didn't have the problem anymore.
Might be a coincidence but maybe it helps

Thanks, I have already tried this with Three, still no better I'm afraid. Might try returning phone for a replacement and see if that helps. Not holding out much hope tho.

Simpler option:
Settings
Mobile Network
Network Operators - and select your original network. It won't roam then onto any other network.

Unfortunately as I'm on Three, they class both 3G and 2G as their network even tho they use Orange network for the 2G side of it. The phone doesn't see any difference in carrier whether is 3G or 2G. So in this case your suggestion won't work.
Thanks for idea though.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, as Three don't have a 2G signal this must be Orange?
Sent from my iPad using Tapatalk HD

*#*#4636#*#* is a nice trick and solves my problem, but as soon as i restart the phone it reverts back to WCDMA preferred? How can i make it to stay on GSM?

I don't think you can keep it on GSM only. Always switches back for me as well.

data connection dissapears after deep sleep/12 hours roughly

not sure why this is happening im using boot image 6.2 and android revolution 6.3.1 baseband radio 2.1204.127.19 and when I come back to my phone the data connection is gone, I have to reboot to get it back
what the heck is going on ?

Are you with three mobile? I had this issue on all roms but today I have fixed this by getting a home signal box so far I've had 5 bars signal constantly and no dropouts no missed calls i would advise getting one but its home only so problem will most likely happen when out and about
