Yes you can,
My understanding is that you will have to do it in person with you and your mom present. You will be doing a transfer of liability - I believe you will lose rollover minutes. You also must pass the credit check.
One thing to keep in mind is that you may have to be 11 months into your contract to do this - at least that is the case were you splitting off your line into your account, this may be different but you may as well be prepared of the possibility.
