No 3G or H Signals

Hi Guys, Had my Desire a couple of days now, contract with TMobile, UK and so far not once have I ever been able to receive a full 3g or H connection. I have travelled a radius of five miles around my home, still no joy. Connects to wifi ok but can only receive g signal out and about,making data and internet painfully slow as to become unuseable. My phone is connected to mobile network in settings. I am seriously considering returning phone under 7 day policy if this persists. Any solutions would be much appreciated.
Other phones with other carriers in my area work ok and according to TMobile web coverage checker states I live in good reception area.
Cheers.

It's possible your sim is faulty happened to my mum when she got her diamond

Try a different handset when they get them instore, might be a device fault.

Check your coverage? Make sure phone settings are set to dual and not just GSM only. I get none at work or home whatsoever. But the coverage checker tells me this anyway.

Probably a stupid question but have you been on the T-Mobile website and put in your postcode to check the coverage in your area>?
Incase you haven't: http://www.t-mobile.co.uk/services/coverage/street-check/
Hope that helps...

and obviously make sure you have 3g on your account?
I'm with orange, and was told i only had a 2g sim card. it took 3 different customer service people until one agreed to send a new 3g one. Not a problem since.

I had a very similar issue.
For the first 2 days i had my handset, it picked up no 3G or H data ATALL. Like you travelled around in about 5/6 mile radius and got nothing. I called up and cancelled, no one told me why or how it could happen, so i proceeded to cancel.
The next morning, i picked the handset up as i was going out, and to my surprise there it was sitting on 3G. Now the night before, i played with just about every setting under Settings > Wireless & Networks > Mobile Networks, Network Mode/Network operators, always-on mobile connection, the lot. Took the sim out, rebooted the phone. messing with those options, or possibly turning them on or off for a specific amount of time may have affected my phone.
The same day i poped into a T-Mobile store where the woman told me hat it could have been down to the SIM not being fully activated, incase a postman stole it for whatever reason.. However, once i got back home i called T-Mobile up again, to cancel the cancelation, which was easy as pie. I told him what i was told in-store he looked up my account and said nothing should have changed as it should have been good to go from the 26th (i received it 29th). I had also noticed just before calling T-Mobile, that 150 from my mobile phone would not connect to T-Mobile, because of that the guy on the phone reset some stuff on ym account their end, told me to reboot my phone, and since then, i've had 3G/H flawlessly and 150 works without problem.
Maybe give them a call and they can help you. Or play with those settings like mad.

I should say ive had randon data drop outs and disconnections even in good signal areas not sure if its normal or my sim or phone

Hi Guys, Thanks for the input. Problem now solved, TMobile re sent connection settings down to my phone, now solid 3g or H around my area except indoors or close to my house. Now very happy, am now starting to love this phone.
Cheers

Vodafone Sure Signal

I have a Vodafone Sure Signal femtocell device, which connects to my broadband and provides a localised 3G signal in my house, as network reception here is poor.
I have 2 other phones connected to the SS just fine, but the One X is intermittently losing the connection and needs a reboot to re-connect. There have been some other posts on the Vodafone UK forums from folks with a One X, not many but enough to make me wonder if there's a more common problem.
Does anyone else here have a Sure Signal, and if so, are you having any problems with it?

I don't personally have it but my friend does and he is getting drops constantly he is not best pleased as he had yellow spot issue aswell aha i think he's going to thro the OX off the wall shortly. He has phoned regarding this and got nowhere

Thanks for the reply. VF have contacted me after I posted on their eforums, I've raised a ticket and they're investigating. I'll report back if anything improves.
VF UK are really pushing the One X, so if there is a problem, I imagine they'll want to get it fixed.

do the vodafone handsets have vodafone firmware? i have a factory unlocked non branded unit I'm using on vodafone with SS and hab=ve had zero problems!

Thanks for the reply. I got mine from dialaphone and it's pure stock WWE. It's working now, but still a little flakey. If it loses connection to the SS, I turn airplane mode off and on again and it works again (quicker than a reboot).
Most of the One X users with problems on the VF forum have their old number on a new sim card, which apparently can cause the Sure Signal to bug out a bit until the new sim is registered. Mine is a brand new number though. It's lasting a day or so before I have any issues.
The SS has always been a little on the flakey side, though, I need to reset it every so often - but that's been weeks or months apart rather than days.
I have one of the older models with 4 lights, not sure if that makes a difference.
Half wondering if it's the phone not the SS, but will see how it goes for the next few days.

I have had very poor suresignal performance...and have swapped out one phone already after speaking to HTC.
But have found that by turning off WIFI, it seems to be a lot happier, and the replacement phone acts just the same as the first (sim free from CPW)
But without WIFI, all data comes out of your data plan, and not from your broadband even thought the SS uses the broadband connection.

I never got to the bottom of my sure signal problems with this phone until I installed cyanogenmod.
However I recently installed sense 5 and my phone would again not connect to my sure signal. I have gone back to cyanogenmod and the problem still exisits.
Can someone who uses a sure signal please tell me which radio you are using by going to settings, about phone, baseband version
Many thanks

Loss of signal, no auto reconnect.

I am having an issue on my One X (unbranded and unlocked) with the signal vanishing and not reconnecting unless I force it. I was wondering 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 also saw a thread with the same issue on T-Mobile / Orange which is also dual carrier.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect.
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 the 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 or is it just networks which use multiple carriers.
My One X is stock and bootloader has not been unlocked.
Thoughts?

Are you still on the 126 SW?
As your unbranded then you should be able to get the 128 update.
With 126, my Three handset recieve level was about -88 to 91dbm.
With 128 its now at -75dbm in the same location.
Most, if not all of the roam to Orange has now been disabled, remaining where there is no Three signal at all.
Steve

No I have upgraded to 1.28, unfortunately I am still in an area where it does switch to Orange 2G signal.
It seems to hang on to 3G until I have virtually no signal, then goes to no signal and doesn't reconnect unless I force it. It seems to mostly happen when I put the phone away on my pocket so I dont notice I have no signal until I check my phone.
I lost signal today and to test the reconnect I left the screen on and I drove about 20 miles through large-ish towns and it didn't reconnect once, had to force it when I got home.
Not sure if this effects single carrier networks, O2 or Vodafone?

Have you had the same issue with any other handset?
Are you a new customer to Three and this is the first you have seen of this?
Reason I ask is when I was thinking of going to Three for my main phone, I tested with a handset I just used for tethering off the one plan.
I drove out of town to an area where I guessed there would be no Three coverage.
The signal hung on for ages but when it dropped I made a note of where it dropped. After a few moments the handset went over to Orange 2g. I then drove back home. I must of drove at least 5 miles past the point I noted earlier before the Orange signal itself dropped and had to force the handset to Three myself.
This sounds similar to your issue and was with a Desire S….but you say you didnt have this with previous handsets. All very strange
Steve

I've had a Desire HD and a Sensation both on Three and never had issue on either of these.
There must be something different about the way the One X handles the switch of signal, or maybe it's just faulty.
Might try some other SIM's from other networks, if that doesn't work I'll get a replacement.

I have this phone second day and I see this signal problem as well, I got iphone 4s in Three and HTC One X in Three as well and in same place Iphone show me 3G connection and 3 bars, HTC show only one bar and sometime nothing.

I'm on three and it never seems to switch to gsm just looses signal all together and takes ages to reconnect once I move location. this is a proper pain I've had the phone replaced three times changed sim still not got better I'm thinking its the radio version on this phone or some software related issue.

If you're phone is from Three you won't get the update until Three release it.
I did see on another thread that Three won't be releasing 1.28 as HTC are currently working on the next update. Don't know how true that is.
My phone is unbranded and unlocked to any network, which is why I got the update.
Think I'm going to get a replacement and see if that's any better, hope it's not a general issue with the one X having lower signal.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, this really improves signal but because it's 2G you are stuck on really slow data speeds.
If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.
I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

Is any chance change three rom on factory rom?

I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".
Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.
This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!
Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.
Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.
I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.
Thanks

I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I think you're best off to return it for a replacement, that's what i'm going to do. Hopefully that will fix my problem and not create any more!!

I have the same issue on my device. On my 2nd replacement and its still the same.
No problems with my iPhone 4S.
Hopefully a radio update will sort this out.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.
Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.

Limited Coverage on ATT

Guys,
I got my unlocked htc one X one month ago. [Tegra 3]. It was working fine for around 3-4 weeks with ATT, call reception and data both working fine.
Suddenly around april last week, i had no coverage at all. Works in some parts of the city and does not in other parts. So, cleared it out with ATT: tried differnet sim, routing to different cell tower and but no use. The phone doesnt pick up reception from the cell tower. Not a carrier issue[confirmed]
So, spoke to HTC, they said this phone is not intended to work in the United states, so we cant guarantee anything. Maximum they can try is factory reset and different sim cards. I tried factory reset and different roms[hoping if the radio upgrade might fix the problem] but no use.
Is anyone else facing a similar issue? ANY SOLUTIONS..
Works at the university, downtown, ATT Store, doesnt pick up service at other places, while other ATT devices work fine..
Any help is welcome
Thanks
mercury5

if your service works properly at all then its probably att. you can try 2 different phones with att sims to be sure. when i leave the county i live in and the data turns off, thats because im on straight talk.

It works fine in other parts of the city, not all but some. Also, when my phone has no reception, other att devices have good coverage. I have also tried different sim cards, none work on my particular phone, so unfortunately its not an ATT issue..
I tried putting my sim in other phones, they receive coverage..

anybody knows any solution to this problem? Any other unlocked HTC one X user from US facing any similar issue?

Having the same issue
I have had my unlocked One X for a few weeks, perfect behaviour until yesterday. Now it seems to pick up a few towers around the place, but nothing at my home or work, which is pretty useless. Turning it on and off seems to make no difference, and I have been googling with no useful results. Did yours get fixed?
I live in Australia.

Nope, mine does not work in my current city. It works in other cities though.
Did not find any solution yet. Also, tried posting at MoDaCo but nothing yet..
Good luck

network no signal
Dear Friends,
I got my htc one X one month ago. [Tegra 3]. It was working fine for around 3-4 weeks with Megafon Rus, call reception and data both working fine.
Suddenly around last week, i had no coverage at all. Works in some parts of the city and does not in other parts. tried differnet sim, routing to different cell tower and but no use. The phone doesnt pick up reception from the cell tower. Not a carrier issue[confirmed]
So, spoke to HTC, they said this phone is not intended to work in the Russian Federation, so we cant guarantee anything. Maximum they can try is factory reset and different sim cards. I tried factory reset and different roms firmwares but no use. Current firmware is LeeDroid.
I bought from cellunlocker.com sim unlock code also no prompt.
Is anyone else facing a similar issue? ANY SOLUTIONS.. Pls.respond.
Any help is welcome
Thanks

I have similar issues. I did not find any solution yet.
I am starting to think that the carriers have something to do with this. It makes no sense that a phone working fine for a couple of weeks just has no coverage all of a sudden. I am of-course shooting in the dark.
Good luck finding a solution. Please let us know what happens

LTE Data Connectivity Intermittent Loss, with 2 Lumia 900's, help needed

I purchased a White Lumia 900 around April 20, updated the phone and have noticed since Day 1 that I was getting intermittent data loss when I was on the cellular connection (not WiFi).
To fix it, I would have to either wait a long (20-30 minutes) time for it to 'fix' itself (which it would only sometimes fix itself), or I would have to either power-cycle the phone or just toggle the Airplane Mode to reset the Cell Radio on/off.
I only noticed a few weeks ago that the data connection loss was happening only on LTE, not 3G/HSPA+.
I went ahead and switched SIM cards. Still the same issue. I then went to my local AT&T Service Center to get a new phone sent to me via the warranty service.
I just received the new Lumia 900 White, tested it out and the SAME thing is happening again! Random data connectivity loss on LTE. What the hell??
The data connectivity loss occurs about every 15 minutes.
Strangely enough, I traveled on business last week to the Chicago area, which also has LTE. I didn't experience the issue there at all.
I am located in the Northern VA area (Reston, VA) - could it be that there are issues with the LTE connection in this particular area?
Does anyone have any ideas on how to resolve this issue? I find it very heard to believe that I am having the SAME problem on two Lumia 900's. I don't think it can be faulty hardware happening to BOTH phones coincidentally.
Any help/guidance would be *greatly* appreciated. Thanks in advance.

I have an idea,
call AT&T and tell them the service in your area SUCKS.
Seriously, once you confirmed it worked fine in another town do you really think its the phone that is at fault? Especially after going through 2 phones and having the same issue?
Obviously you are either in a BUSY BUSY cell area with too many people connecting or your tower sucks.

Thanks for the reply. I called AT&T Support today and they said they would put in a case to look into the LTE service in this particular area. They said it may take up to 2 weeks but they should get back to me on its status.
How much do you want to bet they will either:
1) never get back to me with an update
2) come back with an update, saying "We couldn't find any issues with connectivity in that area"
At any rate, is there ANYONE else experiencing the same issue? My phone has dropped LTE connection about 20 times today in 5 hours.

I work about 8 miles from home and when I travel between the two locations LTE hands off from one to the next without any problem. I did travel down to Orlando a few weeks ago and appeared to have a connectivity issue while at dinner (3 bars of LTE but couldn't download), but I was on my way out the door an didn't bother to pursue it. When I got home LTE was working fine. So the troubled AT&T towers are probably still a good guess.

Me too
I have been having the same issues since day 1, I havent tried to replace or return my phone because I bought it from an ebay seller and I am living in Ecuador, so its kind of expensive just to try to send it back and possibly with no response or telling me that is a network issue of my country.
Each time I go to a place with a weak signal, the phone will go to "E", and the connection wil drop, after a few minutes return to "4G", but the connection won't return at all, the only way to restore the connection is by rebooting.
By the way, I have done like 10 hard resets, and even reloaded the firmware with nokia care suite, and nothing, the problem persists.
My wife is using a Lumia 710, and it works perfectly.
I am using an unlocked lumia 900 from rogers
---------- Post added at 03:15 AM ---------- Previous post was at 03:10 AM ----------
I think the update that was supposed to fix the problem, was made specifically for ATT and another specifically to Rogers, so if you are in other network with this phone you will still experience this issue
