  1. Phone froze up last night, had to take battery out to get phone working. I hope this is not a recurring issue. Like the phone so far.

  2. It says my my rm-975 should support up to 128 SD – I put in a 32 and the phone won’t read it? Advise?

  3. Waaa wooo nice but not friendly user you have to study the system and the functions.
    I always loose my contacts every day I don’t know why.

  4. My grandson had the Nokia RM-975 and it just quit working. Is there anything we can do to fix this?
