this use to be an old virus that was going around it affeced tx msg as well by bombarding your phone with continuess msg contact your service provider and they can reset your voice mail for you they wont charge for this hope this is somr help if not you will have to change service provider but you can keep your same no but they should be able to sort this out over the phone so try calling them first

dear brother the solution for ur prob is
actually your sim card memory is full, that's why the sign of msg memory full flashing on your cell screen.
delete 1 or more than one msg from ur sim card memory.

No, sorry, you can't. The recording is digital and once it's gone it's gone.
