SMS support

Hi dears,

I lost my Import SMS in the Iphone, 4s, because of some problems had happened before. it made me to format my phone before trying to get backups. i wished, had a backup from all my SMS and after this, recover all them. I'm so sorry that cannot change my Iphone in this time but I'm loyal customer for Apple co. Really and Honestly, I Love this companies product and will change my phone to new products as soon as possible. however, I have a question. Is there any ways to get backup from My SMS in my Iphone or not. if it is, would you please help me how can i do this.

thank you.
