Hi there
I have HTC Mozart phone from 1 year. The phone is unlocked, unbranded.
I use our mobile operator (mtel).
But get new sim card (same mobile operator). When put new card- phone notify that no sim card inserted or invalid. When back old one- say no services (it is normal because it is stop from operator). When put other card - phone notify the same- no sim card inserted or invalid.
Is it possible old card lock my phone some way?
Any idea wtf?
Thank u all and sorry for my english.

It is possible for the operator to lock your phone trough the zune updates.
That's what happened to me. So if you have updated it that way its most likely that it has happened to you too.
i am facing a very strange sim card issue.
i am using a demo sim card.. ( a demo sim card is a special sim card that is used to refill the prepaid account of a particular carrier... --this is with respect to india)
The issue is --- i used to refill the prepaid accounts of many people using my sim card.. this was running successfully on sammy's unrooted GingerBread firmware..
but recently i rooted my phone & upgraded to Bezke's Milestone 4 ICS ROM...
Since then i am not able to use that service.. (i.e. i am not able to refill any account)..
has anyone else faced similar issue.... or can any one suggest me a solution..
please help me..
Don't know about demo SIM cards..
But did the phone had a valid IMEI number before you rooted? Has it changed after rooting? If yes.. then search for lost IMEI thread...
If it hasn't and you don't find a solution, try flashing back a stock ROM.. and then see if the SIM card works..
I also guess you can still use the SIM on other cheap feature phone.. Don't see a sense using it in SGS2... Just for topping!!
I always get that grey icon of a sim card with exclamation mark & cannot make any calls. Restarting the phone doesn't work, neither does removing the sim card & putting it back. But imei works and the sim card works aswell . Tested it in an other phone.
Is there any possible way to solve this?
Maybe your Sim-card slot is unclean? Try to clean out it by compressed air or degrease. And also try to wipe chip on your SIM card.
done
Try downloading hck tool
Try usin a small paper sheet on the sim to push it down.. It helped a fren o mine!
Gentlemen, I have a pretty strange problem when it comes to the SIM card in your phone. After installing the ROM - Dirty Unicorns - SIM card I fell as if burned. I checked on various Roma to no avail. None at all read the SIM card in the phone. But after installing the software orginalnego Samsung Sim card work jakgdyby nothing had happened. But as soon as I do root your phone card disappears again. I'm sorry for the mistakes I use Google Translate to communicate with you
background: I bricked my redmi note 3 in the worst way so I had to use test point method to bring it back to live. So I disassembled and assembled it during that process. Both sim slots were working great before that.
Symptom: sim slot 1( the micro size) alone is working fine. When I put only one sim card in sim slot 2 ( the nano size which share space with micro sd card), it show sim card detected then no sim card then sim card detected then no sim card and repeat this forever. When I put two sim card in both of slot 1 and slot 2, neither on can pick up signal and sim 2 showed up and disappeared repeatedly again.
Really hope someone can point me to a direction to fix this. Thanks.

First go here and follow the steps.
And then flash non-hlos.bin from the ROM which is working for you. And, in this process, my IMEI got lost and I manually had to enter using the tool in the above specified thread.
Best of luck
