I have a problem. I was earlier using Nokia E51, it has a feature that I can store messages, contacts and any other thing on Memory card.

I don't find this feature on my BB Pearl 8120. My friends exchange sms with me a lot daily but I've to clear my SMS memory every hour, because I get this "SMS Memory Full" message frequently.

Is there any solution?

Thats because you cannot store those items on a memory card in a blackberry.

Yes, it would appear (to me at least) that its trying to save them to the SIM card, not the internal memory.
Options - SMS
Find "store on SIM card" (or similiar) and change to No.
