Hello,
Is it possible to use a SmartPhone, like C550, without a Sim card ?
I need to run a prog for unlock it, but my SFR sim card blocked the use of it; it ask to me a unlock code.
Thank you for yours help.
Salutations,
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!!
My honor 7 was bricked two weeks ago, i tried several ways to fix it and finally unbricked it with dc phoenix tool. it flashed an emui 2.0 which was never available to honor 7, then flash to B388 stable version(emui 4.0.3) for honor7. The MEID and serial number got lost, so i recoveryed them using hcu client.
now the problem is when i insert a china unicom/mobile sim card which use gsm 2g network, wcdma as 3g network, lte as 4g network, it can detect my sim card and use 2g network. everything seems fine. when i reboot, the sim slot it used will be set as 4g sim card slot, the sim card can be detected, but unable to enable it. reinsert the card back, the sim card cant be detected. but when i use another sim card slot, which is not set as 4g sim card slot, the sim can be enabled with 2g network, everything works fine. when i reboot it, the problem is the same.
now when i insert a china telecom sim card which use cdma as 2g, cdma2000 as 3g, lte as 4g, the card can be detected and setting it to 4g card slot is fine, evening rebooting it, it will still using 4g network. insert cdma card and gsm card, and set cdma card as 4g, everything working fine, both card can be used. but set gsm card as 4g, the sim cards wont be detected.
so now i can only use cdma card, but i don't have one. is there a way to fix it so gsm card can be used? is this baseband problem?
the phone has 2 iemi ids, they seems fine, i verified them on the web, and they are in correct form. but im not 100% sure they are the ids when i bought the phone. maybe flashing the firmware will change iemi just like it changed my meid and serial number? im not sure since i never record iemi numbers.
ps english is not my first language, so if i did not describe something clearly, please tell me.

It's the modem issue . Try to reflash the original firmware
Probably try to flash update.app with is easier like installing an app from sdcard
I tried to flash the latest full stock rom from sd\dload\update.app, that does not help.
Whats the error message?
I know, not many traffic to this phone thread, so probably I won't get any solution, but I'll ask it anyway :
In note 8 I had an adapter to have 2nd sim card outside the phone. Inside the phone I had 1st sim card and microsd.. So I had working 2 sim, and microsd. After updating to android 9 I think , Samsung disabled this, but with a few hacks it was working in android 10 if you were rooted. I'm in android 11 in s10lite.. Is there a hack to enable this? If I go back to android 10, will it work if it doesn't work in 11?
If anyone knows, post.. Thanks,
