How To Fix Invalid IMEI / Change IMEI / Restore IMEI | Without ROOT Access

My mobile is hacked I think

My IMEI sb knows and also SIM(bcoz IMEI is known)

Sb controlling my network whenever he likes

Like I am working on internet than sb stops it and my phone shows 100+dBm for the SIM

Due to this I changed my sim on 2nd Oct but bcoz sb knows my IMEI so this number is also hacked and the same problem began occuring to it…

I'm facing it for 15–20days

Please help it is illegal in INDIA and I tried to many shops and even SIM card official stores but everybody said NO we don't know this…

Well that didn't work fer shit, because guess what's the first thing a carrier offering a locked phone does? Disable 3646633.
