Can I text someone's iPhone with my ipad?

I want to text my girlfriend but I don't have a phone but she has an iPhone and I have an ipad. Will that work?

There's an app for that.

Use iMessage, it works through a data connection instead of over cellular.

Yes, setup your email id (apple id) in the imessages, so she will text your emal address but it arrives as text message to you when you send back and forth.

If you have wi-fi you can use imessage if you have each others email addresses.

IMessage is best bet.

Yeah, but only if you're connected to Wi-Fi on your iPad.

Just tap the messages app, then send your messages to the email address that your gurlfriend uses for her Apple ID.

Yes, just use iMessage on your iPad. Make sure your Girlfriend has her iMessage turned on her phone, otherwise it won't work. You can only use iMessage from iPads.
