How to Send SMS on Wi

SMS Messenger Client
1. Establish a Wi-Fi connection if your device does not already have one. Connect to the wireless Internet signal in your home, Wi-Fi hotspot or other high-speed local network. Your online SMS messenger will use this connection instead of a standard telephone line to transfer the SMS note to your iPhone recipient.
2. Sign up for an SMS messaging account with an online provider if you would rather personalize your messaging or attach it to a permanent line. Try Google Voice or Skype if you do not have an SMS messaging provider in mind (see Resources). Google Voice provides free SMS for Wi-Fi users in the continental United States. Skype charges for SMS, but may still be worthwhile for a loyal user's Wi-Fi-enabled device. Download and install any necessary applications for handheld devices such as cell phones and smartphones if you do not intend to use the Wi-Fi SMS from a computer.
3. Enter the iPhone telephone number to which you want to send an SMS message. Open the SMS function on your messenger utility and enter the number on its dialpad or by using your keyboard or keypad.
4. Write your SMS note in the provided message field. Complete the note in the same fashion you would send an SMS message from your cell phone using its standard service.
5. Push “Send” to submit your SMS message to the iPhone.
