sim 1 signal quality is normal but sim 2 signal quality very poor and no bar in many times but when i check same network with old mobile in the same area it was 3 bar although my asus zenfone mobile signal has no bar. sorry for my bad English
....
Sim 2 is only on 2G, is 2G still available in your area? You may also be hitting a 2G far away as the tower near you no longer supports 2G

i'm at home and when i see my dad old mobile with same network that i have at my room signal is very good (3bar) but my mobile has no bar why ?? my dad has old Samsung mobile (2g only like sim2 of my mobile) not android mobile like me
That I can't explain. You may have a problem with your sim 2 modem, hardware issue.
i also have a problem with my both sims.neither the 3g nor the 2g network is good i checked the sim in other phones and they are fine seems to be my Mobile's problem.i also sent my phone to repair and got some improvement in signal strength but still it seems a little problem with it.
please help me guys what to do now??

You mean Hardware issue of sim card or my phone ??
Yes, your either your sim card reader could be bad or your sim modem inside the phone
I will check another sim card

Anyone got 3G reception at all? My phone is 2G only all the time even though I live in a 3G area. It's set to GSM and whatever the other is auto so I would've thought it should change when it can?
do you have a 3g sim?
Yes as I've just taken it from my HD2
May/may not be relevant:
I have just taken out a contract with TMobile. Their Street Check tool (which allows you to view 2G/3G service in your area) said "Good" for 3G, however when I put my new sim in the Desire at home I was only getting a 2G connection. Was not happy.
Now, a few days later, I am getting 3-4 bars of 3G at home. I don't know what has changed, whether it was a network issue or a handset issue.
Sorry, I know that doesn't help you but I thought I'd share anyway!
After all that, just got 'H' in my flat so perhaps it was a SIM card issue?? Weird...happy though!!
Curious if anyone else had experienced this.
Over the weekend I could not connect to Verizon's 3g network. When I was in a 3g only area, I would have grayed out bars and no 3g icon. I was able to connect to the 1x network and make phone calls. When I was in a 4g area, I could connect to the LTE network and use data fine. I first re-flashed the 4.0.2 factory radios (I had the 4.0.3 leaked radios) to no avail. Then re-flashed the entire factory image and that didn't change anything either.
I brought the phone to my local Verizon store and they swapped out the SIM card. I was under the impression that the SIM card was only used to connect to the LTE network, so i didn't think it would have any effect. To my surprise, the phone was able to connect to the 3g network again.

According to a friend of mine, the SIM card actually holds the CDMA data in it now, so having a bad SIM card will actually mess up your CDMA.
Guess VZW is GSM now.
Yes, over the weekend my sim died as well. Same exact problem. It happened to a friend as well. For us, it happened Friday.

Verizon validates LTE subscribers via the SIM, like a GSM carrier. There is no ESN, as found in CDMA carriers. This is part of their eHRPD bridge from CDMA to LTE. It is also why people couldn't get 3G when the LTE network crapped out last month.
On the plus side, you can swap phones by inserting the SIM now. Welcome to 1995.
The kid at the Verizon tried to tell me that It probably happened from toggling the preferred network mode from LTE/CDMA to CDMA. I hope that the design isn't so poor that this would be the case.

My comment was pretty much tongue in cheek
I can't do a <yoda> and keep a straight face
I'm absolutely baffled that I'm the only one apparently suffering from this.
At first it was ok, now, no matter what ROM or base, the signal quality is terrible.
Where my HTC Sensation was getting full bars, or constant HSDPA (I rarely ever seen 3G), this One X is either getting 3G, G or E, which means no web pages will load or anything, very terrible.
It's making me consider "downgrading to upgrade", because the only time I can browse the net happily is either very close to Wi-Fi source, or where HSDPA is very strong, so I will just about get HSDPA then.
Other people must be suffering from this?????
The only plus with the One X is in my village I find it easier to get 1-2 bars and a bit of G.
Thanks.
Talk Mobile??? What's their coverage like?
Do you know what your Radio is? Try flashing a few different radio's to see if that helps?
Talk Mobile is on the Vodaphone network.
I've never attempted to flash a different radio, in fact I've never even seen a list of radios, as far as I knew they were included in the actual ROMs now.

Afaik some of the Devs have access to different radio's, Try asking Mike1986 from ARHD or Football to see if they can help you.
I'm sure that I've seen some threads about flashing different radios to fix signal problems before, I think to see Mike1986 posting about it when I used to frequent the HTC Sensation's Android Development threads.

It is probably a hardware fault with the phone. If your HTC Sensation is getting a good signal with the same SIM/network provider, and your HTC One X isn't, then I suspect a fault, perhaps internal antenna connection issues that have plagued Wi-Fi. Try gently squeezing the phone with your thumb over the home key and fingers underneath and see if reception improves.
There is also an internal cable that may not have been attached correctly in the phone to the antenna, either way it is back for a repair.
I can't see way a software would be to blame.

I'm using the micro SIM that was provided.
The signal reception bars are never really different, it's just the phones inability to hold a decent HSDPA connection, constantly flicking from 3G, G and E, so I'm loading a website on HSDPA, as soon as it flicks to 3G, loading stops because the connection is far too slow.
I do have the Wi-Fi issue, if the signal is not full on, so I'm a bit away from the router, the wireless is just cutting out all the time, was not like this with HTC Sensation.
I don't really know about getting it sent in for repair I won't have a phone then!
If you get 3G, then you get H, they are the same technology.
What you will find, however, is that the One X supports fast dormancy, so the data connection will sit on 3G until H is needed, then switch, then drop back to 3G when it's not.
you guys tried flashing different radios?
Is it fast dormancy causing the problems then? How can I disable it?
I can't flash different radios as it's very hard to find different radios for the One X
Apparently you have to to change the build.prop to disable it:
ro.ril.fast.dormancy.rule=0

The SIM card doesn't control reception, that is a myth. The SIM card is just like the chip in your credit card, it holds a number and some data to identify you to the mobile phone network.
The problems a self cut or old SIM my cause is that it doesn't connect very well to the phone, this means your phone thinks the SIM card has been removed and gives you "No Service" or Emergency only calls.
The only other time the SIM card may make you think it is affecting reception and giving you a lower signal is if you are roaming and it you don't have an up to date roaming list, usually though this is updated over the air anyway, a new SIM card may allow you to roam onto nearer cells so you see a better signal.
A bad SIM will not knock a couple of a bars off your reception, in the same way a bad credit card doesn't give you less credit limit.

try OpenSignalMaps from the market to see what's really going on (click on 'map' for example will show what cell you're connected to and signal strength etc)
I tried that OpenSignalMaps, I notice how my phone is connecting to some nearby towers, but I live near a place called Selby, and it's connecting to masts in Leeds????
Hi,
I have a GSN2 LTE 7105
i have noticed that the signal bars on the phone keep dropping to 1 bar now and again and it keeps randomly showing E 3g+ and H+. it keeps fluctuating between these.
What im trying to say is that its never stable and the signal bars keep going up n down more often than my iPhone.
Im on the o2 network
Has this got something to do with the way the phone is trying to connect to the 3g 3g+4g and Edge and GPRS signal?
There is no way to switch the 4g.
I have had about 6 notes and all of them suffered this issue.
Any ideas?
if you had 6 notes and all of them had this issue, so maybe it isnt fault of phone? i heard that if micro sim card was incorrectly scissored, it may give weaker signal. But i'm not 100% sure
Sounds like the issue is with your SIM or carrier.

I enjoy my new Nexus 7 LTE very much. But one thing bothers me. I have a LTE sim card in the tablet but I always see 4G symbol beside the signal bars instead of LTE. Actually I never seen LTE symbol since day one I put in the sim. Even at the same time my note 3 can have full bars of LTE signal, the tablet only shows 4G. The note 3 tested 100Mbps down on the speedtest.net but the Nexus 7 only has 50Mbps down when the 4G symbol is on. My carrier is Rogers in Canada. Can anyone tell me if this is normal or something is wrong with my tablet?
Mine always shows 4G only. If I use any other widget (like Zooper widget) that determines and shows connection type, it says LTE.
what's the top speed of your N7 on cell network?

Yes and no for me on AT&T.
I activated a SIM on AT&T on the Nexus 7 2013 4G/LTE and it shows LTE in US.
But, I used the AT&T SIM I activated on Nexus 7 2012 3G on my Nexus 7 2013 and it never shows LTE, only H (HSPA). The transfer speeds on LTE are greater than HSPA on the same Nexus 7 2013 4G/LTE..
Given the Nexus 7 2013 responds different on the same AT&T network at the same physical location just using 2 differently activated SIM gives me a clue there must be some difference in the network settings. I have not yet looked into the details exactly what happens different on the two AT&T SIM but this might help you.
I suspect the network configuration must be changed for LTE access, and it may have nothing to do with the Nexus 7 2013 4G/LTE hardware. It is possible there is some AT&T throttling based on activation but I have no idea how they could do this on a per-device basis (outside my network configuration).

You have to call AT&T to "register" your imei number corresponding to the sim card you are using. Once you do that you will gain lte access. Mine was hspa until I called them.

Just done a test and found something very interesting, just like to report back.
I picked a spot where has very good LTE signal.
First I tested the speed on my Note3 and N7 with its own SIMs. My note3 showed LTE symbol and speed around 80Mbps. The N7 shows 4G symbol and speed around 70Mbps which is in the ballpark with Note3.
Then I switched the SIMs. The note3 still showed LTE symbol with N7 SIM in it. N7 showed 4G with the Note3 SIM in it. The speed test was about same as the first test.
My conclusion is that there is something in N7 doesn't like the Rogers network so the tablet always shows 4G even it is actually connected on LTE network and functioning on LTE speed.

I found it is possible to swap SIM on the same network provider without the tablet noticing, and the results might not change because the SIM settings are unchanged. There should be a tablet reboot involved when swapping SIM, so the new SIM settings are actually applied. I suspect you might have done a valid test, or it may be possible the settings did not update between SIM changes.
What I do is swap out one SIM, insert a SIM from another provider and boot up to configure settings for a second provider or at least clear out the first provider (the SIM does not have to be active), and insert the second SIM from same provider as first and boot up. This has worked very well. It might be enough to simply reboot the device but I don't know if the SIM setting are read and configured every time the tablet boots.
Good luck.

Yes, that's what I did. I power down the devices to switch SIM and power up to test. I've done the testing twice to be certain. If you insert SIM to N7 on the fly, the device will ask you to power off and on to make the SIM work.
