Every time I make a call or receive a call some noise occurs like a screeching or whining sound. I am having troubles with this and please can this be resolved, if I need a new sim or I would like to cancel my contract as this has been going on from the moment I have joined id mobile. I have not had this issue before. 
 

I tried a family members SIM card so it’s not the phone, I’ve tried resetting and airplane mode etc. tried a full restart. 
 

not sure what else I can do?
