SMS or text message is one of the golden egg that generates more and more revenue for most mobile or cellphone service carrier or network operator around the world. One of the reason for big money been made from text messaging service is that it’s actually not so cheap to send a SMS from your hand phone, especially when one is SMS-addict who can’t stop sending text messages.

Lesser known is that, most telecommunication companies do provide free email to text service or web SMS feature. Email to text service delivers the content of the mail message to the recipient’s cellphone as SMS text message, while WebSMS allows users to send SMS from a web form. Both email-to-text or email-to-sms service and Internet SMS service allows users or people without a mobile cell phone to send SMS to the recipients for free, such as trick used by iPhone users to send free text SMS.

However, the usefulness of e-mail-to-text service is not ended just for free SMS delivery. It’s also helpful for user who wants to receive SMS or text notification instead of email notification of alerting system without investing in standalone SMS or text messaging gateway. User can forward the email alert or reminder to phone carrier’s email address to receive message in phone directly instead of sending to normal email address mailbox.

Here’s a list of email addresses or web URL to use for various cellphone service network operator in order to deliver the message via test message or SMS to intended recipients for free. As it’s direct service provided by the cellular network telcos, the delivery of text messages is considered to be reliable, but not guaranteed though. Note that some service provider may require recipient (cellphone owner) to pay for each text message or SMS received, or require the subscribers to activate the email-to-text (SMS) service beforehand.

Note: from, msg, and total means number of characters to deliver in SMS text taken from the sender and content. Number means the phone number of the intended recipient. For USA (United States), the phone number consists of 10-digit numbers.
