My Android is locked.

Question

Someone else created an account for my Samsung Android without my knowledge. The person connected my mobile using "Find my phone" without me knowing it. What can I do to get control of my mobile again? He says that he has not done it. My android will not turn on and I get the message: no SIM card. Can't use my Android. Can somebody help me?

Answer 1

First, try to Factory Reset the phone. Turn if off then press Volume UP + Power until the recovery menu appears. Select Wipe data/Factory Reset and reboot it. Now the phone should be unlocked and working. Additionally, you might need to use a SIM card that is recognized by the phone because it's possible the phone is carrier locked which prevents you from using SIM cards from other operators.
