I have a cingular 8525 that at one point would lose signal periodically but after unlocking and superciding doesn't even find signal anymore... it doesn't say no gsm on startup and rarely connects(i think it connects since i was able to get a text message) i've tried flashing roms, radios but nothing seems to work.. all the pda functions work properly just not the signal... anybody have any ideas on what i can do to fix this problem? or what could be causing it?
Have u tried a new SIM card or another SIM card? Not sure but maybe it will help...
I tried my sim card then found it didn't work well so i went to att and they replaced my sim for a new one and still not much change..
what rom / radio rom is being used?
and i know its obvious but you do have "phone" turn't on in comm mgr? right?
I had similar problem to yours, all I had to do is turn off and on 3G.
it seems i found the cause of the problem.. it was one of the six connectors that touch the sim card.. one seemed to be all the way down and wasn't touching the sim.. i jus raised it up a bit and now seems to connect..

I have a Qtek 9100 running the latest ROM and radio, etc on the Cingular network. The other day I get no signal, and reboot do not fix the problem. I take the sim card, and put it in a different phone. The other phone gets a signal, but says I can make emergency calls only. After about an hour on the phone with a Cingular rep I agree to drive to the store and get a replacement card. The replacement card fixed the problem. 4 days later, I am back to the same problem. The cingular rep is now blaming the phone after they can't figure out whats wrong. He is telling me the phone is "Zapping" the sim card. I find this hard to believe, but has anyone had this problem before? Has anyone ever tried to do an RMA with Qtek? Any help would be great, as i'm ready to put this 9100 on ebay and be done with it, unless an RMA with Qtek is worth it.
Happened to me last week with my 9100 (still running the original ROM). Got a new SIM and it's been running fine since.
i've had my 9100 rom on my 8125 for acout 2 weeks now without any major problems. the only problem I have is that it switches back and forth from gprs to edge a lot, but it doesn't bother me.
have you tried to reflash back to the cingular rom? it couldn't hurt.
I actually am running the Cingular ROM. I already replaced the SIM card 4 days ago, and it worked for about 4 days until it broke again. It doesnt make much sense, because something has to be corrupting the SIM card. When I ran *#*#364#*#* GSM utility, it would give me no data at all. Obviously the SIM card is dead (But still reads contacts on the SIM), and reauthorizing it does nothing to restore it. I will get a replacement today and verify the SIM continues to work in a different handset before I put it back in the 9100. Also I plan to factory default, and upgrade to latest ROMS etc before I try it again just in case. If anyone has any other ideas, let me know. Thanks.

Aqueous, very much the same problem here. I got my Qtek9100 yesterday and I am connecting to Cingular. When I switch on the phone it takes forever to latch to network. The
Y.
Y..
Y... keeps happening for ever and ever. But once, it latches it stays on to it firmly. If I put the sim in my old phone Nokia3230, it just connects to cingular with a snap as soon as the phone is switched on. When I tap on the " Y " region it shows "searching...". I also tried doing a manual/automatic network detection in settings. During the time the "Y. Y.. Y..." keeps going, the manual detection of networks doesnt show a single network in the list. I dont know what could the problem be, since the sim just works perfect in old phone.
By the way, what does

hi im due to buy an o2 xda executive heres what the guy has put in the advert
( It has one significant fault which means the phone functions do not work, as it has difficulty in recognising when a SIM card is inserted. I have used it with O2 and Vodafone SIMs and it was sold to me as unlocked, but most of the time now it says a SIM is not inserted, even when it is.)
what i want to know is does anyone know if this is a common problem and is it easy sorted is it ususaly software or hardware related and is it worth buying if the price is right then geting fixed or is it a problem easily sorted something i could do myself
btw i need help quick if possible before it sells
thanks
Talking about phones in general.. this is usualy a hardware problem.
Perhaps you could find out how old the unit is and (if under a year) claim off the warrenty?
thanks
ahhh cool thanks for your reply
i was just thinking the guy emailed me and said he reset the device to wipe all his info off it and now its showing that it has a sim card in it but he has done this before and it goes back to how it was (showing no sim card )
my question is wouldnt this point more towards a software problem rather than a hardware problem
help update please
right i got the thing now it wont work with an o2 sim
so i popped a vodaphone on in and it worked for a while
then i took sim out looked at sim holder and sim contacts and all looks perfect so i put the vodafone sim back in and im back to the invalid or missing sim card error what next guys ?
when the device boots up i get these three things on the screen
r 1.04.02
g 42.37.p8
d 1.13.82 wwe
i suppose thats the 3 things you were teling me about ?
could someone point me in the direction to the files i need and the order i need to put them on ?
and mabey a quick readthough or point me in the direction of a post relating to this problem
i get similar things when my xda boots too. I am pretty sure everyone does. Does it display an error message with the O2 sim in? Providing the phone is unlocked to all networks, this shouldnt cause a problem.
TBH I cant see that it not reading the sim could be a software problem (someone please correct me if I'm wrong). Even though the contacts look clean, you could try cleaning them anyway. I use the rubber-end of a pencil, or an elastic band if I cant find one. But dont go rubbing the contacts away altogether.. lol
ah right sorry ignore the (suppose thats the 3 things you were teling me about ?) bit in the post that bit was for another forum the reason why i typed all the info on where the thing boots up is because someone told me the radio may be corrupt and to reinstall or install the newest one so thats why i typed all that info and i was wondering where to get the files from in what order to do them and was there a sticky and where is my bloody pencil with a rubber on it !
Just to confirm, you ARE using a 3G sim, right? I don't think it works with normal sims
3g ?
no im not using a 3g sim but the vodafone one i tried worked for a while and that was not 3g i have also cleaned the sim card contacts and the phones contacts to no avail
i have also just unlocked it using the HTC_Universal_Radio_for_SIMunlock_v0.00.00 file
still wont recognise my sim
someone mentioned elsewhere that the radio stack was possibly messed up and i wouldnt be able to use the wireless connection ? but i can so that rules that out ? so its possbily hardware related but all looks ok inside

FYI mine worked fine with a normal O2 sim, bar the 3G stuff ofc
suggestion
try putting a piece of paper between the sim and the battery to push it down a bit. Its a longshot but I know of someone who had a similar problem and it was solved like that.
Hi
That's right try to use a piece of paper stick right behind the sim card to push aginst the sim card to force a good contact, but before doing so try to use a Q tip and small amount of rubbing Alcohol to clean the sim slot metal contacts because from time to time the metal contact might being oxidize and preventing it from a good contact with the sim card. If after trying all this still not work than you might want to try flash it with a new Rom.
any ideas what next please
hi
i have tried the paper behind the sim i have tried the cleaning of the contacts and i have upgraded the radio so as the title says any ideas what to try next as none of thme make my universal think theres a sim in it it just says missing or invalid sim ?
also at the moment my radio is 00000000 so its unlocked but if iwanted to upgrade it whats the best one to upgrade too ?
is it either UNI_radio_1[1].08.00 or is it best to upgrade to UNI_radio_1[1].09.00
and what do i do with the nbf file ? is there an upgrade program please
update

I have a g3 8125 with a modded sofware of wm6. All of sudden today I checked my phone and it is showing that it is searching for a signal and its been doign it for hours now. Does anyone know what might be wrong?
Even i have noticed it happening recently to my O2 mini S also.
Your sim card might be bad.
try to make manual search and see if it detects any othe network this way u will know if the sim or ur network problem or an internal hardware problem
I really need some help here... I bought an imate phone edition from Bahrain(in the Middle East), where it worked fine with the Batelco SIM(Bahrain's network operator)... even when I inserted my airtel(bangalore) sim into it it was reading the SIM(i.e. SIM contacts, SIM tool kit...etc.), so I can't make or receive phone calls, cant send or receive SMS, pretty much cant do the basic functions of a phone... There is an X on the network symbol...
I did a couple of flashes... tried WM 2005,6.1,6.5...etc... now after a hard reset my phone doesn't auto execute anything from Extended ROM and I dont get any Phone signal... All I get is a message that the phone is 'off'... And there is no option to turn it on...
Even it doesn't access SIM contacts, I tried a network wizard and specified AirTel India.. Still doesn't work... Anyone know what I need to do here??? I have a feeling that something important isn't loading from the Extended ROM on startup...
I've unlocked my phone as well(thinking that was the issue) using itsme's tool. Still no effect...
I'm currently using this SIM card on another phone till I can resolve this, so I am sure that the SIM is completely fine....
Any help will be GREATLY appreciated...
I woke up this morning and the signal was good and strong. Then at 10 am there was no signal on the phone. Tried to get a signal outside and no luck. I called T-mobile but they don't really know what is going on. I tried flashing another radio to see if it was the radio and still same problem. Hmmm what could be the problem I am in New York. Any one else experiencing a signal problem? Or if anyone had this problem before and fixed it. Any help is appreciated.
You aren't getting anything? No 3G, Edge or just regular?
Nothing no 3G no Edge nor phone works its stays on searching
hard reset doesn't work either?
Nope ^^ tried removing battery, hard reset, changing radios, and manually choosing carrier... I will try the sim card in another phone to see if its the phone
Call tech support back they told my brother they have had several of these calls but no one called them back after they told them to go change their sim card.
We tried the SIM card in another phone and same thing-no signal. So he went to T-mobile store and was issued a new SIM. Still no signal. In my brother's case it has to be an account problem so your best bet is to start there. Maybe try a SIM from another account, even one from ATT should work.
Got it working Thank you all for the advice. Apparently it was a sim card problem. I got a new sim card and I am up and running ^^
