Q: How do I fix my Iphone? My messages and calls works but my other apps doesnt work and im connected to the wifi.

Hi, Frances941.  

Thank you for visiting Apple Support Communities.  

It sounds like you are unable to use applications that require internet, although you are connected to a Wi-Fi network.  If this is the case, this sounds like you may be experience a self-assigned IP address and a simple power cycle of your wireless network may resolve this.  However, further troubleshooting may be needed and the article below will walk you through some steps for this issue.  

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network
