After moving out from address A where we have a subscription for internet+mobile, I took a new subscription at address B for internet. I would like to now move my mobile number to the subcription at address B, WITHOUT canceling/moving the subscription for internet at address A. Only the mobile part should be removed from address A and attached to address B.
Can someone please tell me how to do this or where to request this? I only find information on full moves.
Thanks,
Nele
