How to Send SMS to the USA

1. Search for a site that offers free SMS messaging to the United States. Three websites that you can use are KalPoint, SMSEverywhere, and 1888USA. Although you may need to register, these are all free to use as of 2010.
2. Register at KalPoint and click 'Search Provider and Country' to find out if you are able to send text messages to your receiver's provider. You will be able to send to most but not all service providers in the United States. Type a message into the the appropriate box and enter the recipient's phone number into the field and click 'Send.'
3. Go to SMSEverywhere and enter the country code (which is '1' for the United States) plus the area code and phone number of the recipient. Type your text message and enter the verification code at the bottom of the page once you are finished. If you are sending a text to the United States, then there is no need to register. This site will also allow you to send bulk text messages to a number of recipients.
4. Go to 1888USA and select the telephone company of the receiver of your message. You will be directed to a page where you are able to create a text message. Enter the area code and phone number in the recipient's field and enter the verification code at the bottom of the page to send your text message. You don't need to register.
