Thanks for your post and for reaching out to the Community Forums, Allanmcc75,
Apologies for the delayed response and sorry that you have not been able to receive calls on your mobile. Have you been able to get this sorted since your post? If not have you been able to try the SIM in another device?
We do also have online mobile help here: https://www.virginmedia.com/help/services-support/mobile
Cheers,
Corey C
