Hey Newz93
Thanks for reply, i have to more than 200 sms dude & the sim card don't have that much capacity, I still thinking how there was no 3rd party application available for this common issue??
Does this same condition apply to other samsung phones like Monte & galaxy's etc.......
I have an idea for this...
1) back up the sms to pc...
2)Flash your phone...
3)Now connect your phone in pc studio mode( with sim card inside)
4)open the sms backup through pc studio
5)Copy an Important message
6)Open Sms sender in the pc suite . paste the message, type your number and send it...again u get ur messages back to your phone

.
Reverse engineering, if not possible from front come from back.

P.S: I hope u have message offer for ur simcard.
