Sim card not recognized!!

Hi to everyone! I recently bought an unlocked Diamond from Germany. I have tried several sim cards on it and each on works but when i try my greek cosmote sim card it shows an icon sim with an x on it and sazs sim card is missing, that means it doesn't recognize a sim card is inserted. When i try this card into a TyTNII that i own there is no problem!! What can be my problem here? The phone is for sure NOT locked to any network!! Thanks for any answers!
it could either be a problem with the Radio not supporting the network (someone else may know more about the bands than i do) or a problem with the hardware, in which case, send it back to where u bought it (if possible).

Diamond wont receognise sim card

i have a problem with my diamond. It only reads my sim card, wont read any other sim card that is inserted. It was originally using XOR morna rom, done a new flash and still same problem. Re-flashed with a original HTC rom, but still same problem. I some how think its not a software problem as it has been flashed/hard-reset numerous times.
Any one know what problem can be or if anyone has same problem, with solution
thanks

Mmmm...
When you say it only reads 'your' SIM card, do you mean it's SIM locked. If you're on vodafone for instance, and you put another vodafone SIM in, does it recognise that? Or do you mean it won't allow any other SIM at all... even if the network's the same?
If it's the first option, your device is obviously SIM locked, if it's the second option, have you installed any security software like Ultimate Theft Alert, or similar, which will also block any other SIMs??
its not sim locked, it was an unbranded phone when i first got it. I am on three and have tried 3 different other three sim cards and also a vodaphone simcard, non of them work.
Its like there is no sim card at all. Im starting to thinbk its a hardware problem not software as i have flashed it few times now with different roms
any ideas, i need to get this working urgently
Mmmm...
Definitely sounds like a hardware issue to me. It's probably time to send it away
Hey Kerm when you put the sim cards does it ask you for for the pin??? or what you could do is see if you can try to clean the sim contact in your phone or run a eraser over the sim card contact and see if there is a difference
had a problem with an unreadable sim-card a few months ago as well; A new sim-card solved my problem... But since you are having trouble with 3 different cards, it might be a hardware problem in your case indeed.
doesnt ask for any pins, as soon as the phone starts up with another sim card inserted, it says no sim card. When it starts up with mu simcard inserted, phone function runs as normal, i can see reception bars etc
I had the same problem when i received my diamond. Tried several sim cards but none was recognized.
I received a new phone because it was a hardware failure.
Sounds like mu has a way of making a new kinda sim lock that only works with there phones ,I would digg a lil deeper and make sure its not a sim lock on your phone
what do you mean by MU, couldnt make it out. How can i find out about if its been sim locked

SIM CARD PROBLEM helP

hello my phone sim card problem I have htc toch daimon does not accept sim card but the problem continues, I unlock sim
My English less
What have you done?
Did you buy the device with this issue, or was it working OK? If it was OK when you bought it, what has happened since? Has it stopped working since you tried to SIM unlock your device?
if you mean, how can you SIM unlock your HTC Diamond then look at the folliwing link on the Diamond WIKI:
http://wiki.xda-developers.com/index.php?pagename=Diamond_SIMUnlock
some older sim cards are not compatible with htc devices
I would request the isp for a new sim card here they send them
free of charge as they would like to keep their customers

[Q] Phone does not recognize any sim

Hi, my phone suddenly stopped accepting any sim card. It shows that sim is not founded even if it is there. What could it be, software problem or I damaged sim reader when was inserting or taking out my sim?

Samsung note 9 sim suddenly stopped working

Hi guys, I have my Samsung galaxy note 9 (N960U) with me. Few days back sim card suddenly stopped working. I tried everything but nothing was working, even I reset my device but sim card is not working in this phone. Can anyone help me in this regard. Help will be appreciated.
Did you try putting your sim card in another phone? If it work's in another phone, the problem is your phone otherwise maybe you have to contact your sim's company to replace the sim card that's probably damaged.
