How to find out who's sending you text messages?

If someone is sending you text messages and you don saknow who they are or recognize the number, how do I find out who they are?

Have you tried sending the person a message to ask who she/he is? You can also try asking your friends if they have that number saved in their contacts list. If this person is bothering you or is a threat to your safety, make a report to the authorities.
