Hi I’d like to get rid of these anti theft messages coming from a phone whose IMEI was changed to one that belonged to a phone I lost a while back. But it doesn’t show on my profile

Hi,

we can’t block the messages for you, if you are sure you shouldn’t be getting those, your carrier shouldn’t have a problem blocking the number for you.

Alright thanks. I’ll check with them.
