Q: how can i have my massages from my old phone to new one?

Hi mahdiehmona,
 

Thanks for contributing to the Apple Support Communities.
 

If you want to move your messages (text messages and iMessages) to your new iPhone, you'll have to transfer all of the content from your old iPhone using an iCloud or iTunes backup. You can find detailed steps for this process at Transfer content from an iPhone, iPad, or iPod touch to a new device.
 

Cheers.
