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

plz plz plz help !
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 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 ^^
Guys
I was wondering if anyone could help please? I have a HTC hero that was lost and has now been found, I have had the IMEI number taken off the blocked list however I cannot get any coverage to the Vodafone network. Everything else is working fine on the phone however when I check in my simcard app under Vodaphone plus it is saying MMI code cancelled and I have no idea why or what to do about it. I am hoping someone can either give me a nice little code that kicks it back to life or can point me in the right direction.
Many thanks!
Your sim card may have been de-activated due to you not using it in a while, not sure though, try using a different sim card on vodafone.
I need help guys! I sim unlocked one of my HD2's for my sister in law to use on AT&T but she keeps losing service..like completely, not just data...I've tried a few different apn settings but no luck. Maybe I am using the wrong ones. Any ideas?
She may have a SIM card issue, have you tried her SIM in another device to see if it still happens? Also make sure the contact points on each side of the device are making good connection to the back cover.
Could also look in Phone settings for network type & put it to GSM only if not already on it & then test ...
