Network unlock problem - Desire Q&A, Help & Troubleshooting

Hi, yesterday I recieved a used HTC Desire that was supposed to be unlocked but when I turned it up and go through the info asking part it asked me for a sim network unlock pin which of course I didnt had so I asked the guy who selled it to me if he could send me the unlock code he got to unlock it and he sent it to me. But to my surprise when I restarted the phone and put the code succesfully, the phone had signal but the sim card on the status bar had an excalmation mark over it, also it doesnt show any carrier name and when I put find mobile networks it says error while searching for networks and nothing else.
Actually the phone has cyanogenMod 6.0.0 installed

[Q] Nowhere to enter unlock code

Hi,
I have bought a HTC Desire 2 days ago which is locked on 3 network (Sweden). I purchased an unlock code but i never got the sim lock screen to enter it. I tried entering all kinds of SIM cards and they all work except the phone will only connect to 3 network , so it's allways on Roaming.
How to enter the unlock code?
FYI: When i received the desire it came with android 2.2, i have rooted it and also installed cyanogen firmware.

but everytime i call out that lady speaks!
i have a SE xperia arc LT15I can anyone help me please?
You posted a link to the unlocking process of the bootloader which has nothing to do with a simlock...as i had some problems with a simlock message appering after installing FreeXperia on mit Xperia Pro i searched the Forums this is something lowlevel and you can't do anything about it aside from get an unlock code when you really have simlock...but since you can actually make a phone call and get a message from your provider i think you should contact them
Bootloader unlocking and SIM unlocking are two separate things.
If you phone was SIM/network unlocked, it is ONCE and PERMANENT. It will not relock.
Contact your carrier.
ok im not going to start other thread now im getting this error
"Your SIM card does not allow a connection to this network"
i tried other sim cards too. but i read here http://forum.xda-developers.com/showthread.php?t=1252019 at post #2
2. Write a Working TA backup from another phone (same model)
3. Restore Security Units.
Thats all, now your phone should boot well but is 90% possible that you dont get Signal so for fix that we need to unlocking.
If this last thing is needed you can refer to this thread:

[Q] [SOLVED] Sim lock or sim card problem ?

Hi !
I just started to play with a Wildfire S sim locked by Orange (Cid : ORANG202).
I unlocked it (but it's still S-ON) and flashed successfully several custom roms (Marvellous CM10, CyanogenMod 10.1, AceOne 2.2).
Then I installed a Free Mobile's sim card. The phone only asked me for the sim card code pin, it was accepted, it but I had no network at all. Note that this sim card works in another phone.
I thought it was a simlock problem, that's why I asked Orange for the unlock code, they gave it to me but ...
My problem now is that the phone NEVER asked me for a network unlock code. I have no network. Some roms display a red cross on the sim card icon on the top bar.
Does someone know what's going wrong ?
I finally got it working after flashing nearly stock rom. The phone finally asked me for a network unlock code !
Thank you for your help guys :silly:

No service/SIM card not being registered

Hello.
I'm from Portugal and bought an HTC 10 wich is locked to T-Mobile.
Already got unlock code for it but i insert a portuguese network sim card and i never get the message to place the unlock code.
I checked the IMEI at T-Mobile website and it shows : Your device is blocked and will not work on T-Mobile’s network.
Already unlocked the bootloader and rooted the phone, thought that would be enough to overcome the T-Mobile app ( wich is to unlock the phone for the network ).
Any tips or comments on how i can solve this issue and use the phone with another sim card?
Thanks in advance
