Phone saying engaged/busy when I'm not
For some reason when people try to call me from time to time it says I'm engaged / busy, however I'm not using the phone at all. Next time they try to call me it goes straight through. I have full signal (EE), full battery, updated software, standard factory settings (I.e.not on flight mode or do not disturb etc), iPhone 5s.
any help would be great!
ps. Why does it say at the bottom of this enquiry form that my content was last saved at 5:41am when it's almost 2pm here? Is this a time difference things between countries / servers etc?
