I was texted by a number I don't recognize on New Years. What should I do?
I do not think you should do anything because if it was someone who is serious, he or she would have tried to contact you again. It may have been a wrong number. However, if it bothers you, get some assistance from your service provider.
ask who its is dont suspect anything suspicous right now
I'd leave it alone. If it were really important, you would've heard from them again.
It was probably just a wrong number so don't worry about it
