Unknown call. help?

Question

look i hate getting prank calls.

i keep getting them and i just wanna know if theres some easy way i can find out the number and call it back.

ive tried a bunch of "codes" but nothing works.

my phone just says the call can be completed.

note:my carrier is t-mobil.

help?

Answer 1

ya cant find out

they are pressing *67

so it comes up as private caller

Answer 2

this person who is calling u is using *67 to block their number.try  dialing *69 on your phone to trace that number.if it keeps happening after you trace go to your phone company and explain the situation.if that doesnt help and the calls get worse call the police or change your number
