It can take up to 3 working days to transfer your existing UAE number over to us, but we will do our best to transfer it before then. We know this isn't ideal, which is why we issue with a temporary Virgin Mobile number in the meantime so you can still enjoy our services.Once the transfer is complete we will disconnect your temporary number, permanently change it to your transferred number and notify you of the change. As such, we didn't design any mechanism to customise the temporary Virgin Mobile number.
