thanks einsten
i did not know that this isnt error or a warrning
i am asking what that means , does my sim or network is hardlocked or locked or softlocked or idk because i have problem i dont have signal i.e network on my phone
I believe it means you do NOT have a simlock or network lock. Else the status would probably be "1" at atlease one of them.
About your signal, have you recently flashed another firmware or ROM? Your baseband might be damaged.
Or did it NOT work when you got it in the first place? In that case you need to take it to support (probably to the company where you bought it, else to a Sony Service Center).

But in settings -> About phone -> Status -> ICCID: Appears the ID from my SIM card, so, this phone read my sim, but doesn't connect to the network.
The phone has an Android 4.4.4 Os Version, and in some places on internet I've read that this version has a problems with, so, I wanted to make a downgrade from Android 4.4.4 to 4.1.x and read this thread: Downgrade Tutorial , but I can't do this because the phone has locked the bootloader (I think this is the problem to make the downgrade), also I tried to put a cyanogenmod firmware from recovery mode, but the installation was aborted in all time that I've tried. Already read this thread about bootloader unlock but my imei is not supported (9900xxxxx) Bootloader Unlock
Well, I also thinked that the IMEI has bad, but I've checked and the phone has a CLEAR IMEI, because in some videos in youtube some solutions consists in change the IMEI number to phone, but to make that the phone must be root, and when I try to install PwnMyMoto the installation was cancelled by Android, also whe I tried to install with adb.
So, please help me with any solution to my phone can make calls and recognize the network.
Thanks, and best regards.

Flash it to moar 7 rom. Everything you want is baked in the rom
what do you mean bro ?

any ideas ?
Moar 7 is a custom rom. Its. Very fast,stable and it does to Hotspot and a bunch of other stuff right out of the box.
Oops reread op you have a g900f.moar is a sprint rom g900p,i saw a flashable zip for hotspot in the forums. Maybe you can try that.
i am afraid to loose the sim unlock or the entire phone if i flash it
because i didn't find cases like mine in the forum
