Well heres the story suddenly my phne stopped using 3G,H networks and only works with GPRS or Edge. The phones logs into te 3G network and 2 seconds later it gets kicked out of the network leaving the phone logged out competely and then I can onlly manualy switch it to use 2G networks only to get the signal back. ANyway heres what i tried to fix the issue so far, I tried my sim card in the other phone and it works fine on both 2G and 3G networks, I inserted a sim card from different provider to my phone still no 3G network, I tried two different radios and finally I flashed my old winmo rom and well same issue.
Im prety much clueless atm what could cause the problem...it sems like a hardware issue so do these phones have separate gsm modules for 2G and 3G?
Ok found my answer

Looks like most of first batch of Kaisers suffered with this issue...oh well 3,5 half years of use is not bad anyway....3G is gone and apperently 2G module should follow soon...time to look for another phone.
Not a bad run for a 5 yr old phone. I have 2 of them, one for daily use and one for testing. They're definitely not expensive to buy or fix (11 bucks for a screen/touchscreen assembly off ebay).

Slide a thick piece of paper between your simcard's back and cover. did you get any change?

Thanks for the tip but it didn't work. Its definitely a hardware issue.Seems like my gsm module is slowly dying on me.
I have had similar issues, sometimes getting kicked off the network, or consistantly the phone would drop calls after about 30 sec or so (consistently i could talk for 30 sec or so and then the phone would drop the call) I also had issues with sometimes not detecting the sim. I disassembled and reassembled the phone and it would start working again. This last time it has been running well after this for a good 6 months or so. I love this phone as for me so far it has been really solid.

There is a device known as re-heater, often available at mobile phone repair centres. Get the TI chip, the smaller Qualcomm chip and the GSM/GPS chip (at the back side of mainboard) reheated. There is something bad with the reflow of solder in the PCB.
ever since updating to the new mango, I experienced battery drain on my hd7.finally I narrowed down to one single cause - sim card.
when I first got my windowsphone, I am using the the old sim card which is 2 years old which was what i got from Telco for my iPhone 3g. IPhone 3g is more than 2 years old.
What i did was i replace my sim card with my sister's Omnia 7 and her sim card is just a month old which she got with her phone.
After using her sim card, i put back my own sim card . And the battery drain disappeared. Asked one of my frens who work in telco service support and he told me apparently my hd7 "learnt" new values OTA from my sister's newer sim card
he claims that the phone downloads software for sim over the air to update optimized for newer hspa networks.
now the battery seems a bit better. And. Does not drain in sleep mode.
I suggest those with poor battery life to try this method.of course it will be better if u got a brand new sim card from your telco
your experience with the new HSPA network will be directly affected with these phones and the old 3G sims, . It only makes sense that when the new network was implimented that a new sim would be part of this puzzle. The sim is your only connection to the network, so I'm totally perplexed as to why this is even in question. The reason you are seeing such high battery drain rates is because the old sim is not connecting to the network properly.
In this case the iPhone 3g sim card does not seems to be optimized for newer network technologies.
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.

vodafone replace my old SIM card for a new one
and the reception problem has been solved
Because the micro chip of old sim cards and different and they work if cutted for micro sim but very bad
old Sim cards are not ready for micro sim phones
New micro sim cards have a smaller "chip" and the y have a better 3G reception
problem solved

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????
I got this rather strange problem/issue with my G5. The 2nd SIM Slot it seems is not that consistent when it comes to network signal. I started noticing this when I put it my Roaming SIM on the 2nd slot, and there are times that it will randomly lose/gain signal strength and the network will totally disconnect. Then I have to again manually configure the network settings. That's when I decided to swap the sims I'm using. The Roaming sim works flawlessly on the 1st slot, while the local sim on the 2nd slot does the same, but so far haven't disconnected from the network, or at least once I noticed it totally lost signal for a second before going back to normal.
Is this normal for the Moto G5? This is something I can't argue with the store from where I got it from since the SIM is accepted and read by the 2nd SIM Tray.
The Moto G5 with Motorola firmware is currently being mis-sold, it is not really dual-SIM as you expect, the second SIM is more an internal storage location - you can switch to it but not use both properly at the same time. When connected with 4g to the first SIM the second is set to the obsolete and not available in many areas 2g. I have found that disabling the first sim is not good enough to allow the second to use 4g, you also have to set the second sim as the primary data SIM. The Moto app suggests you can choose which SIM for data or individual calls, guess it might work if your second SIM network is 2g only?According to report from Australia Motorola are aware of the issue and are looking into it - no 2g signal at all in areas over there. Elsewhere you may have patchy 2g signal and see the old data connections E or H popping up. Apparently older Moto G4 etc can use 3g at same time in second slot, not sure if the G5 issue is fixable by firmware or is some crazy hardware design fault. Don't hold your breath waiting for updates - Android 7.0 with January security update is latest here - while phone still under warranty!
I have my Vodafone esim in my 6pro and the signal is fine on that no problems at all 4/5g pickup is good etc.
But my physical 02 work SIM (not on a 5g plan) - the signal sometimes disappears to the point it says no service and won't come back until I eventually reboot.
Any one else with this issue? Happens even in decent signal areas where I am used to using 02 a lot. And indeed post reboot the signal is good. Never has issues with the same combination of esim/physical SIM on my P5.
My Vodafone esim doesn't have this problem seemingly.
It could be a dodgy connection or the SIM was damaged on moving from one device to another? If it stops responding or crashes (SIM cards have a little CPU and operating system in them) then the phone will drop the mobile connection.
I think all you can do is try cleaning the contacts with something (Isopropyl is a good thing to use) and seeing if that improves things, otherwise try a new SIM.

I'll try getting a new SIM. It hasn't happened on my previous phone with same SIM. But as you say might have damaged SIM during swap.
It's weird it does work for a bit though. But seemingly if I lose signal it doesn't reconnect.
My voda esim behaves as you'd expect.
Someone I know on giff gaf (also 02 network) is having exactly the same issue. Wonder if it's a network thing....
Hope my phone's not knackard
