Hi everyone, I got my phone about 3 weeks ago and worked well (rooted it, then flashed it with a rooted Brazillian rom) till 2 days back, I forgot to register the IMEI with my service provider (using a company phone number) and got my incoming and outgoing calls blocked, but I was still able to use data connection. I didnt give it much importance since I work out country and the nearest office is 3 hours away.
I was able to call using another SIM card (personal phone number) and register the IMEI with my other provider. Couple of hours after that, my signal went dead, I then tried several SIM cards and still no luck. Messing around afterwork, I connected the external antenna to the phone, and I got signal back! I left it on all night on my desk. Next morning came back, disconnected and lost signal again.
My companies SIM card is working well on other phones. The only problem I have is that I need the external antenna connected to get signal.
Has this happen to onyone else? Ive searched several forums with no luck.
--------------------------------
I did some testing and went to the cell tower thats in our camp and got a good signal.
Seems that my internel antenna is messed up or something is not right with the radio.
I dont want to open it until I go back to the city. Anyone knows how to check with an app or something?

Found out what caused my problem and gave it a very simple solution. (http://forum.xda-developers.com/showthread.php?t=1273292)
The problem was that I plugged an external antenna that was a bit more thicker and ruined the internal contact that the internal antenna uses.
The solution was cutting a thin copper wire to 16.6cm long, plugging one end to the middle of the external antenna socket and folding the wire around the battery so it would touch it. Signal didnt go back to 100% but worked at about 90%.

Same problem here! I use a wire connect to external antenna too.
There is any solution for a internal antenna back to work again??
Its seems as a very bad design error

Hi,
I have had my HOX for 3 weeks now and since yesterday (so, not a new thing), I keep losing the signal in my appartment, in some places outside. Oddly enough, signal is OK (tho just 3-4 bars) in my office.
1. Could this be related to the WIFI antenna issue even tho it's not WIFI issue? In other words, is there a chance that by fixing the WIFI antenna issue, I can get solve this?
2. If not, what are my other options? The garanty is already voided so I cannot send it to HTC for repair (voided by an "unofficial repair center" after the screen got smashed by dropping it from like 1m... - it's very possible that the fall or their repair broke something else, but the repair was already 2 weeks ago)
Thanks for your help!
First thing I'd ask is are you rooted? Have you been playing with radios recently?
If not, the next thing I'd look at is trying to find someone else with a micro-sim, and asking to borrow it. If they still get a good signal on their network on your phone, it might be your sim card. I had a faulty one once which just started dropping network like you describe. It can happen.
If their sim card also shows poor reception, you might have an aerial issue caused by the unofficial repair centre opening the phone up. (Although from the feedback on the WiFi issue thread HTC have worrying repair standards too).
If you can't find another micro-sim, just try finding someone on the same network. This phone (when working) has excellent network reception (better than my previous Desire S) so if a side-by-side comparison shows a big difference in signal strength, again I'd think about getting the sim replaced.

If your replacement sim still has the same problem, then I'd consider opening the phone up as per the video guide in the WiFi Issue thread in the general section. Seems to be quite easy if you are careful. It is unlikely that the same aerial for the WiFi is also the 3G one, but I've looked at the tear down pictures, and can't read chinese! If i find out which one it is, I'll update this post. If not, just check all the connections.
Hi,
I have also been having this network drop issue but only near my office. The reason I think is that my office is between two towers and every now and then it tries to balance the traffic on the networks and hence keeps disconnecting devices from one to connect to the other one... However, I have cut out my normal sim into a micro sim and that was done by the guys at the shop from where I bought the device and they had said that if there are any issues, then please order a proper micro sim and use it....
I think that might also be the problem.....

All,
After checking that my SIM card wasn't in cause (used a friend's HTC One X to test my SIM card and test with his), I broke open the case and saw the problem.
The problem is the damn design of those antenna contact! I saw probably around 10 of those small metal piece that are supposed to be a bit "up" and somehow touch the contact area on the back cover.
I found that 2 of them (in two different pairs, they all seem to be in pair to create a closed circuit I suppose) were a little bit lower than their counterpart, so with a flat screwdriver, put them upright, closed the case and voila, I am enjoying network with full bars since yesterday.
If the issue comes back (and it probabl will, if they got bent the first time it probably means that the metal already was bent beyond its elastic deformation area), I'll probably end up buying a soldering iron a add some patch of silver to increase the height of the contact zones. That's .... just lame I am sure they had a good reason to do that, but seriously!?

Glad you got to the bottom of it. Yeah I think the design choice is forced from having the main body of the phone slide in at an angle into the outer case. If the two parts just clamped together like a more traditional phone build, then they perhaps could have used a different approach.
I'm putting off opening mine up (I have the dreaded WiFi drop issue) as my current case puts just enough pressure on the screen to act like a permanent squeeze, halting my problem.
Would be interested to know if the problem reoccurs like you said it might. Keep us posted.
Hi,
I am not sure but after my phone fell from 50cm table! my phone always shows "no service".
I changed my SIM card and flight on/off mode. It didn't work.
The other phones sees the signals but mine doesn't.
Yesterday I recognized that if I am very very near to the link of the service provider (say 100m) I have signal! and can connect.
I think my antenna has vey poor performance. Do you have any idea to fix it?
Thanks in advance.

Same problem! It randomly lost service signal, and now I am missing signal everywhere except in a big city, but even there I mostly don't have signal. I have tested this with 3 other friends who have the same service provider and have 3 out of 4 bars - while I have 0.
I lose signal when the phone is in my pocket, when holding it below a table/desk (in school), when holding it wrong in my hands. It's a really annoying problem and I'll send my phone back today.
Try squeezing the phone a bit, maybe it slided around inside the case a bit and lost the connection to the antenna
Sounds strange but fixed my Wi-Fi temporally (at the end I bend up the antennas a bit...)

That only works with Wifi, but the wifi issue is already fixed on my phone.
Yeah so I dropped my phone down the stairs and it destroyed the screen. :crying: So I bought a replacement and everything works now again except I have no service. It says Network unkown, signal -113, unknown mobile network typer, and out of service service state.
HELP!!! lol
thanks
Have you taken it back apart and checked the antenna connection yet?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
yeah everything is hooked up, even took it BACK apart twice to make sure, the antenna goes up the right side to a board that looks like it connects to the removable piece at the top, it is plugged into the main board, even unplugged it and replugged it.
Does your phone show the correct imei? Defective sim card? Defective sim reader?
Yeah the IMEI is correct, the sim card works in my other phone. Any way to test the sim reader? It shows the correct phone number, and it will load my contacts.
I'm not sure how you can test the SIM reader. I was just listing a couple of things that may be causing the problem.
It is possible that your ribbon is not seated well. Have you checked that?
Which ribbon? I am pretty sure I plugged them all back in.
Shouting out for any help.
I've got a Samsung Galaxy note 2 N7105.
About 9 months ago I replaced the motherboard with a secondhand board from a broken phone and all was good.
Last month I decided to listen to some music using headphones and it was very crackly, but improved if I squeezed the phone case.
Quick check on google and apparently its a common problem , so dismantled the phone (again) and cleaned everything up. Put it all back together and hey presto ! .. Audio was working fine... BUT then I noticed that I had no mobile signal.
Without a sim installed I have 3 or 4 bars, although I have no idea what network its getting that from !... When I put the sim back in, the bars disappear and I get the not registered on network error message.
I've tried automatic network selection and manual but it makes no difference.
I've dismantled the phone and made sure all the sockets and wires are where they should be but still cant get a mobile signal with a sim in.
Wifi works fine.
Any thoughts (apart from throw it away !).
Thanks in advance.
You could try to replace the SIM/SD card reader.
I recently replaced the mainboard on a Note 2 GT7105 only to be confronted with SIM card problems on that mainboard. It would not register my SIM card.
I have paid around 10€ including shipping for a new SIM/SD card reader and have now a working phone. Replacement is straight forward, look it up on youtube!
For the audio...I have exactly the same problem, cracking/distortion when using the headset...speaker is normal. I have tried all the suggestions I could find on google and have come to the conclusion it is a bad contact in the connector between the mainboard and headphone jack. To be more precise, the problem is on the mainboard side on my note as I replaced the headphone jack module...I have given up since. Really disappointed as I had invested in a new frame chassis and almost new display. I will use this phone as my GPS, this phone has a GPS fix within 10sec in my house! Never seen such a powerful GPS in a phone...

Have you checked your imei ?
Also, check network anntena cable properly locked in.
I bought a supposedly new HTC 10 off ebay a few months ago, and just realized on a recent trip that location service is using only wi-fi & cell. Once I am out of signal range, I get no location data, and GPS not working.
The phone came S-OFF and running WWE software, which I have changed to US unlocked using RUU, currently running 2.51.617.32, baseband [email protected]_76.02_F.
From a previous contact with HTC, they told me the serial number is that of a Sprint phone. I am assuming that this is a refurb of some kind.
I have installed GPS Status and tools, and the app can see the satellites, but cannot get a fix. Hardware check says that the sensor is OK. I have cleared AGPS and that made no difference.
Changing data from 3G to LTE to Auto, or on & off (per a couple threads at xda) made no difference.
I am unsure what to do next. Phone works well otherwise. Would flashing a Sprint radio help? perhaps a different kernel?
Any advice appreciated. TIA.
I had this issue after a battery replacement. Essentially this thread worked for me. Once the HTC 10 was opened up and the rear casing removed, there's a v. small copper prong located next to the headphone socket and it needed a bit of careful prying so that it could make contact with the back plate of the phone once rehoused.
So it could be that your new phone off ebay is a refurb and has been previously opened?
I would try a Sprint ROM before opening it.

finally found someone with some 10 repair experience haha. I just noticed my GPS won't lock, assuming it's due to screen/battery repair. I have over 5yrs phone repair experience, so salty i am in this spot.... But I have been many times with HTC repairs, and eventually figure out hte querk. Any other insights? I opened it up yesterday and couldn't get a lock still even without back frame shell on. I then noticed the top pin above the headphone jack was depressed most likely due to prying when opening, i carefully bent up and it didn't break, now making connection with back cover frame but still no gps lock.... also try reconnection of the top daughter board flex where hard gps chip lives....
Update: Twas the pin at top, and flashing RUU that got me up and running GPS again! woohoo!
Thanks by the help!
The last week I change the battery and I lost the GPS signal. After reopen the phone, the GPS pin it was in bad position. After move the pin, the GPS it is working again!
