Increasing speed of the phone is able to do in a few ways, and the one
of them is move the data from the phone’s memory to mass memory. Some
users who use Nokia N series phone have a problem while doing this.
They can’t move the messages stored in the phone to the mass memory.
So, if you’re experience in this problem, what should you do?

There are a few ways you can do to move the messages stored in Nokia N
series phone to the mass memory and might it works also in other Nokia
phones. Firstly, choose the memory you want to use if you go into
message settings and find the option to change where messages are
kept. And then your Nokia phone will ask you if you want to transfer
the messages over. Here you can save the messages by using PC Suite
before delete the messages stored in phone memory.

Now, to save the text messages to the mass memory, you can go to
messaging => options => settings => others => and choose which memory
used for store the messages. But for your notice, if you would change
the memory back to the phone memory, you probably loose the moved
messages.

Another method used to store the messages is using Nokia PC Suite or
Nokia Communication Center. Just tick message you need to store and
then go to Menu => File => Export. Move messages by use this way only
able to do one by one.

The last method is using Lifeblog or Nokia Phones which both are Nokia
applications that also available to storing the messages. However the
best solution of the problem above is by regularly make backup of
messages in Lifeblog, Nokia Photos or NCC, but the memory for messages
should be stored in phone memory.
