The jamming device suppresses the mobile phone by sending signals at the same frequency and high enough power to make the two signals collide and cancel each other.The mobile phone is deceived into thinking that it has no service because it can only receive one of the frequencies.Some jammers only block one of the frequencies used by the phone, which has the effect of blocking two frequencies.To interfere with your phone, you only need a device that broadcasts at the correct frequency.
