I have had several Motorola phones over the las year and a half, and have noticed that every single one of them only allows 20 text messages to be stored in the inbox. Yet I can store a million and one in the outbox. Is there something I can do to the phone to allow more storage space in my inbox? Or is this something I need to take up with my service provider? Right now I am using a Moto V555 through Cellular One, BTW.
