Just got my 7100t this past Monday and noticed that it saves all IM replies/responses onto the SIM card. I know IM's are sent as SMS's but didn't know they were saved to the SIM card. I noticed this when I inserted my SIM card back into my old mobile (SE T610).

Is there a option I can change so that it doesn't save to the card?

Options > Settings > SMS

first option: Leave messages on SIM Card: No

I already have that option set to "No" but perhaps, by default, it was set to "Yes" and I just don't recall changing the option.

Thanks for your reply.
