how to turn off stolen siren on my phone?

guys, need help urgently here… i forgot i’ve activated remove sim card siren on my phone. as i put my sim card back on to my device the phone keeps showing “this phone has been lost or stolen” text and sound. i went to avast website and remove the device from device list but still didn’t work, then i tried to get the license back but got replied that no listed device (because i’ve removed it). what should i do now to get my device back to function?

sorry if this is not well written as i’m not a native english speaking. hope you understand my issue here clearly. thanks beforehand

Hello,

you could have used the online interface to unlock the phone and/or change the avast! PIN. since the connection got broken, we’ll have to try other ways. I’ve sent you an email with details.

Just to check how it is working, I marked my mobile as LOST. The SIREN was ON. I gave the PIN to unlock. Then I marked my mobile as FOUND, also sent the command SIREN OFF. But whenever I switch on my mobile, the alarm sounds. I have sent the command SIREN OFF so many times thru online, still I have the problem. please help me.
