I put one of my SIM cards into a new N97-mini. The memory on this SIM, according to my old Nokia 7600, is only "almost full" - room for another few SMS - current total 166. However my N97-mini is flashing that the SIM memory is full. When I look for SMS to delete there are none displayed apart from the welcome text.
Any ideas what's going on? The manual says find something to delete, but there isn't anything to delete.
