I have recently moved to ID mobile from Vodafone. Since then, if I am scrolling on my phone and someone tries to ring me, it comes up with a missed call and the caller hears it go straight to answerphone. All of the fixes of lengthening ringing time are irrelevant as it rings fine when I’m not on it. 
 

I’ve missed some really important calls that I can’t call back like the hospital. The phone is in my hand! Full WiFi and signal. I now have to have my phone on the table if waiting for a call. This has never happened with Vodafone and started straight on switching. 
 

This also happens to my husband. When I ring him it often goes to voicemail too so I know to just ring back. We will have to switch as it’s a deal breaker, what happens with the contract though?
