How do I get iChat on my iphone

Hi Psirmmy,

Thanks for posting in Apple Support Communities! If you're referring to iMessage, which is is a secure messaging service that you can use to send and receive messages on your iPhone with other Apple device users, follow these steps to get started:

1. "Go to Settings  > Messages, then turn on iMessage.
2. To select the phone numbers and email addresses you want to use with iMessage, go to Settings > Messages > Send & Receive, then choose from the available options below 'You can receive iMessages to and reply from.'”

-Set up Messages on iPhone

Those steps will enable and activate iMessage on your device. Once activated, check out some tips on how to use the service here: Use Messages on your iPhone or iPad.

If you're referring to another service not offered through Apple directly, we suggest checking with the developer or support team for that service to see how to set it up.

Cheers!
