I have switched over to ID mobile. When signing up it gave me the option to click keep number.

I downloaded the eSIM and looked in the settings to switch over from current provider to ID mobile but there is no number there or no data usage allowed. 

I've signed up to the app, however, when I've signed in, it asked me to update my id mobile. My understanding is I was never given a new mobile number and when I put in my current mobile number it doesn't allow me and then just logs me out. Please do assist
