my iphone cannot activate using my apple id and password

You need the Apple ID and password that were used to originally set up the phone.

If you are the original owner, contact Apple. Apple can remove the ID  if provided the required paperwork. 

Request additional support for unlocking your device

Either take the device, the original purchase receipt with the serial number, and a photo ID to the nearest Apple Store (if it has reopened). Call the store before going to make sure they can help.
